THAI BINH SUBPROJECT BACKGROUND INFORMATION Fig. 1: Subprojects Locations in Tlhai Binh Province I.1.Subproject 1: Water Supply Development for Dong Hung District Town (Ref. Drawings in Annex /L.1) Subprojects locations: I | - Province: Thai Binh - District: Dong Hung l | - Commune (town): Dong Hung . 1. 1. Brief Description of Subproiect 1: The proposed subproject aims at providing clean water supply systems for some 5,330 inhabitants in 1,523 households in Dong Hung district town. This subproject is expected to supply sufficient water for domestic, commercial and industrial purposes of local community in adherence to national planning guidelines. Piped water shall be supplied round the clock with minimum pressure of 1Om and be treated as per Clean Water Standard of the Ministry of Health given the supply source capacity in Hoa Mac of some 800m3/day. The Subproject also encourages installation of septic tanks with support from rotation funds with the aim to enhance sanitary condition and enhance awareness on community health. Capital cost is relatively high as the unit prices increase at district level because the facilities capacity is small and population density here is lower that that in urban areas. However, the operation cost is I equivalent to current level thank to savings from effective performance which will offset high capital cost of a small-size facility. The WB asks for participation of at least 60% of population to execute the subproject. In Hoa Mac district town, as much as 60% of local inhabitants is reportedly willing to pay 27,000 VNDlmonth/household for piped water. The implementation of subproject in Dong Hung is then feasible.

Selection of Supply Sources | Survey results by design Consultants (BVI and VIWASE) show that: I * Groundwater: Dong Hung district town in Thai Binh province is the coastal flat area, a part of the triangle of Red River Delta. Regarding geological setting, Thai Binh in general and Quynh Phu in particular are located in Quaternary of sediment system (Q), in the sunken area of Hanoi Geological survey background in the area is reported as follow: * From 1988-1992: the Geological Mission No.58-Union II for Hydrogeology investigated the groundwater in north of Thai Binh province (north of Tra Ly including Hung Ha, Quynh Phu, Dong Hung) l | From 1993-1996: Union II for Hydrogeology (Department of Hydrogeology) created hydrogeological rmap, scale 1: 50,000 for the whole area of Thai Binh province. | | According to geological and hydrogeological records, Thai Binh province including Quynh Coi district town is located in the Quaternary of sediment system having the origin of mixture between river and sea. From the ground to the consolidated (Neogen rock) there are different hydrogeological units as follow: * From ground to depth of 1 2m (thickness is unstable, possibly be smaller): is the aquifer in Holocen sediment, Thai Binh formation (( QIV3 TB ). This is the uppermost aquifer, lithologically comprising of sand powder and clay powder. The dug wells and a number of drilled wells normally take water from this aquifer. However, this aquifer is of poor productivity and unstable availability. a Confining layer- Hai Hung formation, upper QIV1-2hh2: is distributed at depth 12-30m, or deeper in places. The lithological compositions include mainly clay, sandy clay, non-water bearing powder clay. 3 | Page 9 ,41ts;wt0Er)nllItI/aI c-iJ.ft'.1lld"III f Ial, iu'0 ! ,l; A'l,bProj,qj * The intergranular aquifer in the Holocene sediments, secondary formation Hai Hung QIV1-2hhl: at depth of 22-55m, or 60m at places. It's lithologically composed of power sand, fine sand, thickness I ranges from 20-40m. Currently, the UNICEF drilled wells in the town mainly use this aquifer. However, this aquifer is incapable of supplying water with large volume. According to analysis results of samples taken from households' drilled wells at depth 58m (Table 1.2), the Fe content is I very high, 9.2mg/l. * The intergranular aquifer, Vinh Phu formation Q1112 VP2: is found at the depth of 52-70m with average thickness of 20m. It's lithologically composed of non-water bearing clay * The intergranular aquifer in the late Pleistocene sediments, Vinh Phu formation, under Ql112VP1: is distributed at depth 70-80m, thickness is not stable, changing from some meters to tens of meters. 1 he lithological coimipositionis mainly include mediuin-size sand and coarse sand. The static water level is near the ground. In Dong Hung, well No.10 in south bank of Nguyen Bridge was drilled to this aquifer with depth of 70m, discharge 0 = 11.5 I/s; transmisivity coefficient K=354m2/ng, the drawdown is 6.33m, influencing diameter 200m. | The intergranular aquifer-Hanoi formation Qll-llllhn2: This aquifer is located at the gravelly sand layer, Hanoi formation, distributed at the depth of 80-85m with unstable thickness. The lithological compositions mainly include clay, powder clay and non-water bearing sandy clay. * The intergranular aquifer in the early Pleistocene sediments, Hanoi formation QI1-llllhnl: this is the aquifer of north Vietnam in general and Thai Binh province in particular, distributed at the depth of 95-150m. The average thickness is 50-60m. rather stable. It's litho logically composed of coarse sand, gravels. The grain size increases according to the depth. It's possible to exploit water from this aquifer for centralized supply. However, water deeper aquifer show sign of salinity. Analysis I results of sample taken from 98m-deep drilled well near district town Health Clinic show that the Chlorine content =326mg/l. 2. Remark In Dong Hung district town, based on hydrogeological investigation results and field survey of some production wells, it should be preliminarily concluded that 2 aquifers are potentially selected, that are intergranular aquifer, Holocene sediments (Qa) Q,v 2hhl and late Pleistocene sediments (Qb) - Q1112VP1. However, Qa aquifer is suitable only to small-scale water supply of UNICEF drilled wells. Qb aquifer is distributed unevenly in depth and area, with unclear availability. In Quynh Coi district town, there is only one well drilled to Ob aquifer, depth =98m, capacity 15-20m3/h, operate 6h/day Surfacewater (Tien Hung river) In Quynh Coi district town presents only Tien Hung river (Chau Son My) flowing in Northwest-South Eastern direction, originating from Luoc river in the Northwest. According to records of Irrigation Department of Dong Hung province, the Yen Long river water flow is measured as follow: * Highest: +1.5m (flooding level) a Lowest: +0.5m X Maximum discharge (recorded in flood season): 40,000m3/h * Minimum discharge (recorded in dry season): 4,000 m3/h Page 10 Tien Hung river is a branch of big river, thus having significant discharge. According field investigation results, this water is served as major supply source for production and domestic purposes of the district town. Analysis results of river water samples taken 25th August 2003 show that water is of moderate quality and can be used for domestic purposes. Rainwater is not entirely clean as flowing down from house roofs and unclean containers. However, if initial rainwater is excluded, rainwater is clean 3. Selection of Water Sources Based on field survey results and existing data, following comments shall be made: l Groundwater: Within the district town, even though detail survey and potentiality assessment is absent, based on the hydro geological maps of Thai Binh province and data collected from field survey on the current groundwater status, it can be preliminarily concluded that the groundwater source in the district town can meet the requirement of a water supply system with capacity of 1 ,OOOmlday. Therefore, in order to have reliable basis on the water reserve, there should be supplemented hydrogeological survey at the proposed well field to define exactly the capable water aquifer to be exploited, the ability and availability of aquifer. This need investment and time for implementation Surface water Tien Hung is a branch of Luoc river with Nham Lang intake dam being head river and salinity preventive dam at the debauching point to East Sea, thus it can regulates water discharge during the year. The river has rather great flow, satisfying the need for irrigation and domestic supply for the town. River water is flowing, thus the cleaning capacity is high. At the same time, the river is next to district town, thus it's favorable for construction of WTP. Therefore, given the absence of groundwater feasibility data, the Project shall use Surface water of Tien Hung river for supply to the WTP Thus, in addition to rainwater used by households, the Project propose surfacewater from Tien Hung river for centralized supply. The treatment technology mainly comprises: Coagulation, settling, rapid filtration or filtration with floading materials, rapid filtration to remove suspended solids, then disinfection. However, when selecting surfacewater from Tien Hung river, there shall be measure to protect water source. Discharge of domestic wastewater by residents along river banks must be restricted, use of chemicals, organic fertilizer for fertilizing trees along river sides within protection zone must be banned. Wastewater generated by industries must be treated to desired level before being discharge to river. Soaking of jutes, sedges in the river must also be prohibited to maintain good river quality and protect the environment. Page 11 Subproject Ccreening Based on Exclusion Criteria l 1.2.

However, these two aquifers are distributed unevenly in depth and area, with unclear availability. In Quynh Coi district town, there are some Page 17 r¼II2JI')tiiif idfII c/ls Jt ,Jig,g., I fo'or g7I,li 1J3i,:Il .hl'bprojeecl I production wells exploiting water from this aquifer, i.e well in District's Hospital with capacity 6-10m3/s anid operate 8 hours/day 3. Selection of Water Sources Based on field survey results and existing data, following comments shall be made: Groundwater: Within the district town, even though detail survey and potentiality assessment is absent, based on the hydrogeological maps of Thai Binh province and data collected from field survey on the current groundwater status, it can be preliminarily concluded that the groundwater source in the district town can meet the requirement of a water supply system with capacity of 1 ,OOOm3/day. The main water aquifer can be selected is Q1112VPi and Qi_iIi,hni. These are potential aquifers with good water quality. However, in order to have reliable basis on the water reserve, there should be supplemented hydrogeological survey at the proposed well field so that the information on water aquifer which are going to be exploited, the ability of supply as well as the water quality will be exact. Surface water Yen Long river is a branch of Luoc river. The damp gate Ben Hiep is at the head river, therefore, it can take the role of regulating the discharge of the river throughout the year. The river discharge is at moderate level and is now the water source for facilities and residents in the district town. However, the river is seriously contaminated due to industrial and domestic waste facilities and | residents along the two river's banks. Based on existing data and screening of above findings, the Project will select the groundwater as major supply source. Conceptual Design of Groundwater Exploitation Work On the ground of existing hydro geological condition and water demand of the Project, the production well shall be as follow: Table 1.7.

Brief Description of Subproject i The proposed subproject is to provide clean water supply systems for some 11.015 inhabitants in 2.623 households in Hung Ha district town. This subproject is expected to supply sufficient water for domestic, commercial and industrial purposes of local community in adherence to national planning guidelines. Piped water shall be supplied round the clock with minimum pressure of 10m and be treated as per Clean Water Standard of the Ministry of Health given the supply source capacity in Vinh Tru of some ,1700m3/day. The Subproject also encourages installation of septic tanks with support from rotation funds with the aim to enhance sanitary condition and enhance awareness on community health. I Other general components are similar to that in Dong Hung and Quynh Coi district towns. The WB asks for participation of at least 60% of population to execute the subproject. In Hung Ha district town, as much as 60% of local inhabitants is reportedly willing to pay 21,000 VND/month/household for piped water. The implementation of subproject in Hung Ha is then feasible.

Selection of Water Source The results of survey by the designing consultants (BVI and VIWASE) show: * Groundwater source: Hung Ha district town-Hung Ha district in Thai Binh province is the coastal flat area, a part of the triangle of Red River Delta. Regarding geological setting, Thai Binh in general and Quynh Phu in particular are located in Quaternary of sediment system (Q), in the sunken area of Hanoi Geological survey background in the area is reported as follow: * From 1988-1992: the Geological Mission No.58-Union II for Hydrogeology investigated the groundwater in north of Thai Binh province (north of North Tra Ly including Hung Ha, Quynh Phu, Dong Hung) * From 1993-1996: Union II for Hydrogeology (Department of Hydrogeology) created hydrogeological map, scale 1: 50,000 for the whole area of Thai Binh province. | According to geological and hydrogeological records, Thai Binh province including Quynh Coi district town is located in the Quaternary of sediment system having the origin of mixture between river and sea. From the ground to the consolidated (Neogen rock) there are different hydrogeological units as follow: * From ground to depth of 12m (thickness is unstable, possibly be smaller): is the aquifer in Holocen sediment, Thai Binh formation (( QIV3 TB ). This is the uppermost aquifer, lithologically comprising of sand powder and clay powder. The dug wells normally take water from this aquifer. However, this | aquifer is of poor productivity and unstable availability. * Confining layer- Hai Hung formation, upper QIV1-2hh2: is distributed at depth 12-30m, or deeper in I places. The lithological compositions include mainly clay, sandy clay, non-water bearing powder clay. I * The intergranular aquifer in the Holocene sediments, secondary formation Hai Hung QIV1-2hhl: at depth of 32-70m, or 75m at places. It's lithologically composed of power sand, fine sand, thickness ranges from 20-40m. Currently, the UNICEF drilled wells in the town mainly use this aquifer. Within Hung Ha district town, there are two water facilities in Dong Tu 2 and Minh Khai commune, capacity of each facility being 10m3/h, depth = 70m. On the other hand, in 1991, Hydrogeological Union No. II trial drilled 2 boreholes in the center in the town (near Police Station) with depth =85m. * Page 22 Test pump results said 32m3/h, which means that this aquifer is capable of supplying water for centralized purpose with high discharge.

The lithological compositions mainly include medium-size sand and coarse sand. The static water * level is near the ground. - Surface water source: Tien Hung river originates from Luoc river (a brach of Red River),-flows across Hung Ha district town, then debauches to East Sea. The river crosses noth of the district town and serve as boundary between Hung Ha district town and Thong Nhat commune. . Page 23 According to records of Hung Ha Irrigation Department, Tien Hung river crossing the district town is measured: * Highest: + 18m * Lowest: +0.15m * The highest discharge (records in flood season) may reaches 40,000m3/h * Lower discharge (records in dry season): 3.500m3/h Tien Hung river is a branch of big river, thus having great flow. According to field survey and investigation, this is the major supply source for production and domestic purpose of the town. Table 1.9.

Several production wells are also found in Hung Ha district town taking water from this two aquifers: Dcong Tu 2 and well near Police Station, with capacity recorded at 6-lOm3/h and working duration 8h/day. Otn the other hand, based on the hydrogeological maps of Thai Binh province and data collected from field survey on the current groundwater status, it can be preliminarily concluded that the groundwater source in the district town can meet the requiremenit of a water supply system with capacity of 1 ,700m3/day. The main water aquifers can be selected are Q1i12VPi and Or, irilhni. These are potential aquifers with good water quality. However, in order to have reliable basis on the water reserve, there should be supplemented hydrogeological survey at the propsed well field to confirm on the information on water aquifer to be exploited, the ability of supply as well as the water quality. | Suifacewater (Tien Hung river waterj Tien Hung is a branch of Luoc river with Nham Lang intake dam being headriver and salinity preventive dam at the debauching point to East Sea, thus it can regulates water discharge during the year. The river has rather great flow, satisfying the need for irrigation and domestic supply for the town. However, the river is currently contaminated by waste discharged by enterprises, agencies and residents living along river's banks. 3 Selection of Water Source. Based on existing data and screening of above findings, the Project will select the Groundwater as 3 major supply source.

ENVIRONMENTAL IMPACT AND MITIGATION MEASURE /111.1 Environmental Impact During Site Clearance Stage During this phase, the most significant impact is land acquisition and destruction of vegetation cover for construction of WTP, drilled wells, intakes and the Network. However, as the construction area is small and lies mostly in agricultural and bare land, thus the environmental impacts is very minor. 1. Land acquisition * Reqardinq Dongq Hunq DT: The WTP is located in the agricultural land of Nguyen Hung commune (rice field), with the area being not large (1 ,746m2), thus the impacts on land acquisition is riot a significant one. The distribution Network is installed mostly along the traffic road of the project site. Right after construction time, the site will be restored to the initial condition. Therefore, influences associated to land acquisition for this component is also assessed as minor. * Regarding Quvnh Coi DT Since the proposed WTP for Quynh Coi DT is sited in area of 1404.2m2, in the bare land of the I Agricultural School, the impact during site clearance and compensation is very low. Collection and supply network is designed running along local foot paths, which shall be restored for use * after construction phase, thus the impacts are evaluated as temporary and rminor. Well GI, G2 and G3 is along Road No.217, within the land of bodies such as Preservation Agency, Food Company and DT's Bus Station. This land belongs to Provincial Water Supply Company and Local Authority, land acquisition shall be taken into proper consideration. * Regarding Hung Ha DT The land acquired for construction of the project is also agricultural land and bare land, thus land compensation and acquisition shall be easy and favorable. In addition, the land area is small (1,698.4m2), the impacts anticipated during land acquisition is negligible. Wells Gl, G2 , G3 and G4 is along National Road No.39, rice fields, public land and bare land of the DT, the impacts is also very minor. Collection and Supply pipelines for runs along public footpaths and National Road No.39, which shall be restored to the initial condition, thus the impacts shall be minor accordingly. In short. Since the land acquired for construction of the project components (WTP, Network, wells and surfacewater intakes) is small, the impacts on the environment is minor. * Page 27 Il 2. Destruction of Vegetation Cover. The land used for subproject construction comprises mainly public commons, bare land and partly agricultural land. During construction phase, the impacts on the vegetations cover in and outside the proposed WTP, wellfields, and raw water conducting pipelines. The area of destructed vegetation, however, relatively small, comprises mainly of wild weeds, dry crop and rices, the impacts are unavoidable and accordingly minor. 111.2 Environmental Impact during Construction of WTP and Network 111.2.1 Impacts on the Soil Environment, PM and Noise durng Construction Time. During construction of WTP, collecting wells, and distribution network, the impact on soil, PM and noise is minor as the work volume is small, wells are far away from each other (separate). The contractors will apply technical measures to minimize impacts on the environment. In order to minimize impacts on the soil environment, air emission and noise during construction time, the following mitigation options shall be applied: - Mitigation of PM Restriction of generated particle matters during construction time: minimizing dust generation by sprinkling, step-by-step construction, installation of temporary fences around the construction area, well construction management and supervision. - Control and Mitigation of Exhaust Gases * Do not use old machines (not registered and permiKted by the Vietnamese Registry Agency) as the exhaust gases shall exceed the permissible level. I Strictly observe standards and maintenance schedules (or use of alternative fuel) to reduce air pollutants. - Control and Mitigation of Noise * Restrict vehicles' speed within construction area to 5 - 10 km/h, * Machines and equipment generating exceeding noise and vibration shall be allowed in day time only. Operation from 10 pm to 6 am shall be prohibited, In the event that night working is needed to ensure schedules or technical requirements, there must be permission of local authority. * Do not use old machines and equipment as the generated noise shall likely be higher than allowable level. The noise insult shall be maintained regularly. * install noise insulation devices in areas of high noise level (asphalt batching plant, concrete batching station, roller, bulldozer, etc); and * equip workers with noise insulting tools. Page 28 l - Labor Safety | All workers on the construction site shall be trainied oni safety regulations and labor rules. 111. 2.2 Impacts on inundation, hydrogeological regimes During construction of conducting and distribution Network, there shall be inevitable impacts on the existing wastewater drains along roads, particularly the ones in DTs' centers. These influences are, however, minor as the construction time is short and step-by-step construction methods are applied. Besides, in case the distribution cut across the existing drains, temporary sewers shall be constructed to prevent any possible impacts on water drainage. 111.2.3 Nuisance to Local People, Traffic Congestioni and Harm to Infrastructure. The supply pipelines for Thai Binh DT has comparatively small diameter of 100-150mm, specifically: I For Dong Hung DT: 790m/13,493m For Quynh Coi DT: 1980m/1 2250m For Hung Ha DT: 820m/1 5870m Supply water pipelines for Thai Binh DT mostly have small diameter (<80mm). Most pipelines are buried on sidewalks at depth 0.5-0.7in. Excavated eaith miiaterials is filled immediately on the spot, and no I tiansportationi of surplus earth materials is needed. By doing so, rio significant impacts on the environmental is anticipated. Installation of pipelines in crowded roads/streets in DTs' center shall likely create nuisance and impacts on businesses and daily routines of local population, traffic movement, particularly in the area crossing I important traffic road (Provincial road No.217 in Quynh Coi DT and National No.39 in Hung Ha DT). These influences are inevitable. Construction time shall be in off-peak hours. In sensitive locations, constructioni shall be executed at night time. Constructed site shall be recovered right after completion. In area where construction need longer time, temporary roads shall be paved, using wooden plates or steel sheet to facilitate circulation of pedestrians. Surplus waste materials must be collected and disposed off properly. Materials for construction shall be mobilized to the site just in prior to construction tirne. Sign boards shall be installed or flag men provided to instruct traffic. Construction sometimes necessitate destruction of pavement, sidewalks as well as other structures where the pipelines cross. In the event of this, proper methods will be proposed in the design to nminimize this impacts. After construction time, the contractors shall coordinate with relevant units to consolidate and restored the disturbed pavemnents, sidewalks to their initial conditions. Appropriate nmeasures shall also be taken to reduce the impacts on drainage sewers disturbed by the constructed pipelines. If found necessary, temporary drains shall be constructed to ensure normal drainage for the region. * Page 29 111.3 Impacts during Operation Phase 111. 3. 1 Increased infiltration of oollutants into aquifers (in QuVnl? Coi, Hung Ha D T) Water extraction fr-om Q1112VP1 and Qii-iilhn, w in case of Quynh Coi and Qjij2VP1 and Qiv1 - 2hhl in case of Hung Ha may create depression cones in aquifers. This will facilitate movement of water from upper aquifers as well as suiface courses from channels, ponds, lakes, paddy fields into deeper aquifers through hydro geological windows. Infiltrating water from upper aquifer and surface courses contain soluble pollutants, which can alternate the initial composition. Most of the wells area is formerly rice field and dry crop land, thus the infiltrating surface water will likely take a certain amount of chemical fertilizers, agricultural chemicals, thereby polluting the groundwater aquifers. During extraction process, flow of underground courses increases substantially. When flowing across area containing such acids as humic and fulvic, iron in water will react with these acids, creating humic acid, sulphur or silica colloids, etc. This will reduce pH value in groundwater, create difficulties for treatment of iron later on, and unpleasant smell and odor. Extraction also create depression cones as mentioned above and raise the concentration of pollutants. Movement of water form other part also increase dissolution of pollutants and lead to the increase of some substances as As. Surface water (Dong Hung) Sources of potential surface water pollution during operation phase comprises: Domestic and production wastewater of local people residing along Tien Hung river sides, which is within the protection zones of wellfields of Dong Hung DT. Water contains residues of agricultural chemicals and fertilizers from in-field channels. Normally, local people apply some 20kg of fertilizer and 100kg of alkali/sao (360m2)/year to stimulate paddy growth. Additionally, 0.5 kg/sao/year of pesticides are used. During fertilizing and pesticide spraying process, residuals shall follows water courses and end up in Tien Hung river, affecting water quality. However, * this impact is minor as the amount of pesticides and fertilizer used is not much (25,000 kg of alkali and 5,000 kg of fertilizer) and for along time (2 crops/year) and mostly absorbed by trees, the residuals amount is very negligibly small. 111.3.2 Operation of the WTP * Impact on the Air, Noise and Vibration During operation stage, the environmental pollutant sources are mainly form: * Treatment of raw supply water by using alum and other chemicals. ! I Page 30 * Noise and vibration from secondary pumping station, air blower, etc. The noise level is moderate, affecting only direct well operators. * Impact on Water Environment Wastewater from aeration constitutes a source of environmental pollution. This wastewater contain high concentration of suspended solid, making water in and outside the WTP muddy. The wash-up water | shall be treated before discharging into the environment. * Solid Waste Solid waste generated during operation of the WTPs comprises: * Small volume of domestic waste (few staffs in WTP), * Solid sediments from settling tanks and filters, | Sediments in filtration process includes mainly Fe2O3 and MnO2 residues. Others sediments likes CaCO3 is negligible. I This sediments shall be dried up, packed and transported to prescribed disposal sites of the DT. 111.3.3 Assessment of seftlement As mentioned aboved, subprojects in Quynh Coi and Hung Ha DT use groundwater for supply. Normally, there are two options during groundwater extraction as follow: Option One: (Scenario 1) O Groundwater is very abundant | Extraction with capacity exceeding allowable levels. Land subsidence Option 2 (Scenario: 2) 3 Groundwater is not abundant Jr Extrction in various location and exceeding tolerable limit Interferences creating subsidence. Regarding 2 subprojects in Quynh Coi and Hung Ha , capacity is reported as: - Quynh Coi DT: 1,000 m3/day - Hung Ha DT: 1,700 m3/day. | Page 31 &,tlm7;1'o,,,dt11 c/ijLeJititrid few ghi7hB,tihl JIthpbprjeed U Extraction volume in these two district towns according to preliminary survey results is lower the design capacity. Thus no risk of land subsidence is anticipated 111.3.4 Mitigation Measures during Overation Phase Extracion Wells (Quynh Coi and Hung Ha) * Keep periodical maintenance schedule, cleaning-up pump. When abnormal changes are reported in | wells, pumps, extraction pumping shall be stopped for careful examination. * Check the raw water quality regularly. When changes on water's chemical compositions, particularly pollutant tracers are reported, the reasons should be quickly found and mitigation taken. If there is no treatment method, or treatment is too expensive, the wells shall be closed and sealed. b. Measures for Reducing of Depression Cones (Quynh Coi and Hung Ha) | Drawdown of water in drilled wells in Thai Binh province can be attributed to the following reasons: * Exhauston of recharge sources * A number of wells are close to each other | * The extraction volume exceeds the capacity. * During extraction tme, capacity of extractng wells is reduced due to sedimentaton of residues in water, I which seals up the screen pipes and reduce cohesion of stone near screen pipes. The factors leading to the reduction of water capacity of drilled wells likes regional rapid economic development, weather changes, etc is not within scope of this project. The only following measures are proposed to enhance capacity of drilled wells during extraction time. * Calculation and well selection of wells location, which ensure sufficient water for long-time supply. I * CLeaning up of wells, in case the wells are sealed by materials with grain size bigger than the nets or holes on screen pipes, the screen pipes can be cleaned. * Chemical treatment of screen pipes: According to survey results, materials sealing the screen pipes and cohesive soil and rock near the screen pipes are attributed to iron hydroxide and Magnesium. I During this process, Chlohydric acid with concentration from 18-35.2% shall be used to change Iron hydroxide, CaCO3 from insoluble into soluble compound. * Propaganda and awareness raising on the responsibility of water sources protection, making them well aware of the need to save water, reduce extraction capacity to ensure stable supply sources. l * Page 32 /AIL2ird')IiIIltIIltI dlJJJiieiiiit III f)l /' lItIJS / 'Iil lt c4Ip'jkdR c. Reductfon of the Water Contaminaton Mitigation of the risk of ground water contamination is not mere matter of subprojects, but of various provincial agencies and bodies. The following issues shall be paid with due attention: | * Construction of safe protection zone for surface and groundwater. I Develop solid waste management and urban sanitation plans of subproject, usage of fertilizer, I construction of flush toilets. | * Promote improvement of knowledge and propaganda via mass media to make every inhabitant aware of and responsible for protection of groundwater in Thai Binh province in general and in subproject in particular from contamination and exhaustion in order to protect public health and sustainable exploitation of this precious resources I c. Chemical Safety The chemicals used during the water treatment process will be mainly alum, lime and chlorine., of which chlorine will be used in the pure liquefied form (compressed in the pressurized container) is of highest environment risk, while the other chemicals such as alum or lime will have inconsiderable environment risk. The liquefied chlorine will be compressed in pressurized containers design with technical parameters ensuring safety. The average dose of consumption will be 1 g/m3, and when necessary (when occurs epidemic diseases, or when cleaning the pipeline) the dose of consumption will be 2 g/m3. The total amount of chlorine consumed in 1 month will be 1,393 kg. During the operationi process the whole system will be subjected to regular inspection arid monitoring; I An automatic alarming system will be installed to warn when the chlorine amount exceeds the permissible limit; a ventilation system, and a toxic gas collecting system will be installed to collect the | gas before discharging to the environment. e. Sanitation The water plant already has the regulations on the places of discharging solid waste, on the periodical cleaning around the water plant and has contracted with the URENCO for transporting the wastes to the places of disposal. Therefore the sanitary conditions of the water plant area will have no impacts on the water source. * The wastewater will be collected and treated through the septic tank system before being released to the environment.. * There are regulations to forbid strictly the use of fertilizers, chemicals or grazing domestic animals in | the protection zone. * The water plant is enclosed by walls and guarded round the clock to ensure security for the machinery, equipment and water source. * Page 33 rtgg,jertuinIet,fu/ c4iJ?Jiltf itl for *'7Ihai BArth. Jtubprojszet f. Safety and Accidents | * The using manuals of the equipment and machinery used during the operation stage must always be with the equipment and machinery, The technical parameters must be checked regularly. | * Notice board must be provided at the places of danger. • Good signal light, fire alarm and communication system must be established. The technical I pipelines such as chlorine, alum, lime etc. pipes must be painted in color according to the regulations. * There must be adequate safety and rescue equipment such as oxygen respirator, water tanks, fire extinguishers, etc., must be prepared. * There must be personal safety equipment such safety cloth, rubber boots, hand lamps, and safety belt. * A separating fence must be established to isolate the dangerous areas such as the power station, chlorinie store, etc. g. Impacts and mitigation measures during the stage of operation of the transmission system The pipeline used will be spherical cast iron pipe of ISO 2351 - 1991 K9, with inner anti-erosion layer according to ISO 4179 - 1985 and outer anti-erosion layer according to ISO 8179 Part - 1995. The working pressure of the pipeline will be 6 bars, therefore the possibility of pollution from the wastewater collection system into the transmission line will not be likely. In order to limit the impacts on the | transmission line and the valves, notice boards in the area passed by the pipeline shall be provided, regularly maintain and check periodically the pipeline, develop rescue measures when the pipeline breaking accidence occurs due to the external or internal factors (Summary of mitigation measures is introduced in table 111.1) IV. ENVIRONMENTAL MANAGEMENT PLAN According to the Vietnamese Law on environmental protection and WB's requirements, during the stage I of project construction and operation, a Environmental Management Plan (EMP) shall be carried by relevant bodies. It is important to monitor main environmental parameter to enable changes to environmental condition to be detected and actions to be taken before significant impacts arise The purpose of the EMP is to provide guidance on how to ensure the environmentally sound project. In order to obtain the required effectiveness, the EMP includes environmental mitigation program, environmental mitigation compliance program, reporting requirements, institutional arrangements for EMP implementation and emergency measures. * | Page 34 Table 111.1.

The environmental monitoring reports and environmental mitigation compliance monitoring reports should be made during each supervision time (every three month) This three reports shall be submitted directly to PMU after control. The last overall report shall also be made for submission to the PMU based on the results of all the controls conducted during the entire construction phase. V.2 Environmental Monitoring and Reporting during Operation Phase V.2. 1 Monitoring and Reporting on Raw Water Quality The monitoring of water quality will be according to the existing program of Thai Binh Water supply company. The water quality indicators have been set forth in the master plan of Thai Binh Water supply company. Monitoring of raw water quality shall be implemented weekly and quarterly. In case when incident are reported, raw water will be monitored daily. Samples are collected immediately at the water intake points (surface water) and wells (groundwater)., , After being collected may be brought to the laboratory of Water Supply Company for analysis. Analytical indicators includes: * Surface water (Dong Hung DT): TSS, turbidity, content of chlorine, agricultural chemicals residuals, N02, N03, NH4, Coliform. * Ground water (Quynh Coi and Hung Ha DT): pH, NH4, Cl-, N02, N03, SS, Cd, Cu, Zn, Mn, Pb, Fe, Phenol, Coliform. The results of everyday analysis will be recorded in the record book of the WTP and every month the enterprise will have responsibility to prepare a report on the results of analyzing raw water samples and send the periodical reports to the Thai Binh PWC for supervision. In addition to raw water supply monitoring, during operation stage other parameters such as air is monitored. V.2.2 Monitoring and Reporting of Treated Water Quality. Treated water quality shall be monitored regularly at reservoir before flowing secondary pumping station to the Network. Water samples will be regularly taken and brought to the laboratory of Thai Binh PWC for analysis. The main analytical indicators to be determined everyday will include: pH, SS, NO2, NH4, N03, Cd, Pb, Cu, Zn, Mn, Fe, Phenol Fecal, pH, electric conductivity, salinity, alkalinity, hardness, KMNO4, iron, Coliform, NO2, NO3, will be analyzed periodically every month. The residual chlorine amount will be measured immediately in the field. In average 5 samples will be collected everyday. Additional samples will be collected in the day if the customers have complain about the water quality.. Page 40 4mtw);,rartmetthi c/lijejtAstridB ./oi, gl J$;,l ()'ith Auprooiee I The quality of raw water and finished water must be in compliance with the national standard on clean water TCVN 5942-1995 and standard Nol 329/2002/BYT. In average everyday 1 sample of raw water and one treated water sample will be analyzed V.2.3 Monitoring of Noise, Air and Waste Sludge The noise shall be monitored at pumping station, and microclimatic parameters shall be measured at chemical house every thiee months Monitoring of waste sludge shall be executed every 6 month, V. 2.4 Monitoring of Drawdown For subproject using groundwater s supply sources (Quynh Coi and Hung Ha DT), the water table shall be subject to changes during exploitafion process. Therefore it will be necessary to set up a water level gauge system to monitor alternaton of water table and adjust producton capacity to ensure water quality and capacity duriing exploitaton process. In this regards, static and dynamic water levels will be monitored monthly at producton wells. Wells are cleaned up once a year. For subproject using surface water as supply source (Tien Hung river water in Dong Hung DT), a level gauge i i system shall be provided next to intaking facilifies to monitor the changes in water level and tmely notfy Irrigation Agency for proper adjustment of flow. The water flow may be monitored by visual method everyday at the intake and recorded in the record book by WTP's staffs V.2.5 Institutional Responsibility for Water Monitoring The agency responsible for monitoring of the quality of raw water and treated water is the WVP in cooperation with Thai Binh PWC to monitor the water quality daily and monthly. Agency supervising the compliance with the environmenital regulations: U - The Prophilactive health Center and the Thai Binh DONRE are 2 agencies supervising the compliance with the environmental regulations of the Thai Binh PWC, directly WTP water supply enterprise, V.2.6 Urgent Rescue Measures * |*a Plans for daily water storage will be prepared (reserve tank system) in the case of emergency or in the case of polilution of the water source * Measures for preventing accidents, for chemical safety, especially with the disinfecting chemicals, must be always imparted to the workers responsible for the operation of the water plant. * Provide sufficient information signals, alarming in case of accident occurred. The emergency respond system shall always be checked and ready for use. Page 41 I 1 VI. TRAINING PROGRAM In order to ensure effective implementation of set out EMP, training and awareness raising shall be organized for technical staffs and workers of the WTP, specifically two training courses as follow: * One training course for Monitoring Supervisors during construction and operation phase. This course is targeted towards technical training on environmental supervision. Participant shall be some 15-20, training time is one week. Training cost is estimated at 40-50 million VND. * One course for workers during construction and operation phase. The course shall cover such as contents as capacity building on implementation of mitigation measures and labor safety. Training time is estimatedly 2-3 days, participants are 100-115, and estimated cost 20-25 million VND. * Trainers shall be Consultant Environmental Specialist. VII. CONCLUSION | The water supply sub-project of Thai Binh province is implemented in 3 locations: Dong Hung, Quynh Coi and Hung Ha district towns. * Quynh Coi and Hung Ha district towns use groundwater source, whereas Dong Hung use water of Tien Hung river. I * The environmental importance of the water supply sub-project is that whether the management of quality and reserve of water source, quality and quantity of treated water meets the requirements of environimental standards. * The EMP must be prepared appropriately and feasibly. For this purpose, the stipulations in sections V and VI above must be complied.
