(Ref. Drawings in Appendix 11.1)
Subprojects locations:
- Province: Ha Nam
- District: Duy Tien
I l l - Commune (town): Hoa Mac
1.1.1. Brief Descrjition of Subprolect I
The proposed subproject aims at providinlg clean water suipply systems for some 3,600 inhabitants in
937 households in Hoa Mac 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 1 Om and be treated as per
Clean Water Standard of the Ministry of Health given the supply source capacity in Hoa Mac of some
I | 800mn3/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 * 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
equivalent to current level thank to savings from effective performance which will offset high capital
cost of a small-size facility.
-I The WB asks for participation of at least 60%/o 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
VND/month/household for piped water. The implementation of subproject in Hoa Mac is then
feasible.

/Xw.9;,^6.t,d,,./. i.§sos.etifw #)r 7t,0, 8t,a,i, S(doprojee(jI_-Suirfacewater:
Hoa Mac is associated to 4 rivers namely: Red, Nhue, Chau Giang river and Duy Tien channel.
+ Red River: lies some 4km east of Hoa Mac district town, with average flow of 3.200m31sec. Theriver is rather large, with availability ancl quality ensuring for domestic water supply. However, duringrainy and flood seasons, the concentration of suspended matters is relatively high, not favorable forraw water collection, conduction as well as treatment.
+ Nhue river: oiiginates from Lien Mac gate in Flanoi, stretching 74km long and merges into Dayriver in PlLi Ly. T he river also has a brancih connected to Chau Giang, flowing across Hoa Mac. Rivebed is some 35-40m wide.
+ Chau Giang river links with Red River via Chau Giang gate.
+ Duy Tien chaninel or called Hoa Mac river: is a small river, some 50m wide and 21m long, flowingacross Hoa Mac district towin. This river is connected with Nhue river at Cau Gie (Gie bridge), andanother branch linking to Chau Giang arid Nhue river at Phu Ly provincial town.
Consultants has carried out survey and sampling and analysis of Hoa Mac river water. Analysisresults reveal that Hoa Mac river water is seriously polluted due to its close association to Nhue river,which bears direct influences of urban, industr-ial wastewater from Hanoi, Ha Dong arid traditionalhandicraft villages along the river. Flow direction of Hoa Mac river depends on operation regime ofChau Giang gate, lying some 4 km away and linking to Red river. Hoa Mac river has turbidity of 25NTU, NH4 ' value is 1.1mg/l with reported organic pollutants froml urban and industrial areas. ThePhenol content reaches 0.0064mg/I. Aloni( the tow sides, numerous sanitation work of localresidents are reported.
I Table 1.1 below and Appendix I (Table 1 and 2) present the analysis results of groundwater and riverwater samples in Hoa Mac district town.
* - Rainwater is not entirely clean as flowing down from roofs and storing in unclean containers.Excluding first rainy days, later falling amount is however considered to be clean.
- As the results, in addition to rainwater used by households, the subproject has selectedgroun-idwater at depth 80m for centralized siupply because of good quality arid sufficient quantity.I Groundwater is generally not polluted, or at minor level and be treatable. Treatment processcomprises mainly of aeration, flocculation, rapid filtration to remove iron and Mangan; then

Each househiold then have access to two water resources.
At Frozen Factory in Dong Van district town, there are tWD treatment facilities with 04 number 25mdJeep, lOOmm dia drilled wells with design capacity of 20 m3/h each. Currently, the Factory only run3 1-2 wells. Treatment process includes aeration by spraying, rapid filtration and secondary pumping.
Drainage and sanitation status
Most population in Hoa Mac district lives along traffic road, thus a drainage network here is almostabsent. Rainwater, domestic wash wastewater gravity flows and drains to river, gardens and nearbyfields.
I Following sanitation works present in Hoa Mac district town:
I - 31% of population has toilets with septic tank,
- 16 % has latrines with composting,
- 1 3% has latrine of open pit type,
- 17% has flush toilet,
* - 20% has latrine, and
1 - 3% has no toilet.
1.2.3. Selection of Water Suppl\ Source
Survey results by design Consultants (BVI vp VIWASE) show that:
Groundwater:
I + Holocene aquifer presenting in Dong Van district town comprises of fine and medium sand,lalluvial clay with depth ranging from 1 0-40m, averaging 1 7m. Static water is subject to seasonal
| fluctuation fi-om 1.05-1 .4m. Some test drilling show that exploitation capacity may reach 25m31h.
* F'leistocene aquifer present at depth 45 - 50m. In Dong Van area, the depth of this aquifer is28.5m with relatively high conductivity. Static water table is recorded at 1.4-2.5m, subject to
seasonal fluctuation. Tested flow may reach 34.7litter/s, Concentration of NH4 ' is 6,25mg/I, Fe?-I | = 11,9mg/I, Cl- = 954mg/I. The deeper the layer, the higher the senility level. In the area ofFrozen Factory, capacity of exploitatino well is 20m3'h, iron content reaching 26 mg/I (table 1.1).
| The Holocene aquifer is 0 - 25m deep, averaging 8 - I5lm. Static water table is 2 - 3m.
1I
Surfacewater
Surfacewater source near Dong Van is Nhue river. Nlhue river serves as the drainage river for Hanoi,Ha Tay and Ha Nam region. Nhue river bear the influences by direct urban and industrial wastewaterfrom Hanoi, Ha Dong and traditional handicraft villages along the river. Therefore, Nhue river water is
seriously polluted..
Design Consultants has surveyed and taken water samples from Nhue river. Analysis results showthat water is dirty, with signal of organic pollution from urban and agricultural sector. The Phenolcontent reaches 0.008 mg/I. Analysis results by Center for Environmental Engineering of Town and
Industrial areas (CEETIA) show that in [)ong Van, BOD5 content in Nhue river is 10 - 25 mg/I, COD15- 40 mg/i.
Groundwater and Nhue river water in Dong Van is presented in Table 1.1 and Appendix I (and Table3,4,5)
- Rainwater is not entirely clean as flowing down from roofs and storing in unclean containers.Excluding first rainy days, later falling amount is however considered to be clean.
As the results, in addition to rainwater used by households, the subproject has selected Holocenegroundwater aquifer at depth 25m for centralized supply because of good quality and sufficient
quantity. Groundwater is generally not polluted, or at minor level arid be treatable. Treatment
process comprises mainly of aeration, flocculation, rapid filtration to remove iron and Mangan; then
sterilization (ref drawinig in Appendix 11.2)

- 45% has latrine of open pit type,
- 2% has flush toilet, and
* - 5% has no latrine.
1.3.3. Selection of water source
The results of survey by the designing consultants (BVI and VIWASE) show:
| " Groundwater source:
The Holocene aquifer in Vinh Tru area occurs at the depth of 0 - 35m, in a fine sand layer with an
I average thickness of 17m, a static water level of 2 - 3 ni below the surface. In general the water
sources is of low potential, commonly for extracting the groundwater from this aquifer, the
|households use small diameter UNICEF drilled wells with hanid pumps, which can extract up to 1 -
2m3/h. The results of analyzing the water samples from a 8 m deep drilled well at the district People's
Committee and some other UNICEF wells show that the iron, manganese and ammonium contents
are relatively high. The total iron content is up to 7.2 mg/l, Manganese 0.5 mg/l and the ammonium
content is 1.26 rng/l.
Besides the Holocene aquifer, in Vinh Tru area occurs also a Pleistocene aquifer with the depth of
45-70m below the surface, with the thickness of aquifer of 15 - 30m. Transmissibility coefficient is
I 700 - 900 m2/day. However, this aquifer has been salinated. The salinity increases with depth. At
60m deep drilled well, the content of Cl- = 939 mg/I. Static water level is 2 - 3 m, dynamic water level
changes from 5 - 15m depending on place.
Surface water source:
At the Vinh Tru town there is only Chau Giang river. This is the main water source which may be
used to supply water for Vinh Tru town.
The quality of groundwater and water of Chau Giang river in Vinh Tru is described in Table 1.1 and
appendix 1 (Tables 6, 7, 8).

111. ENVIRONMENTAL IMPACT AND MITIGATION MEASURE
111.1 Environmental Impact During Site Clearance Stage
1. Land acquisition
* Regarding Hoa Mac DT.
The proposed WTP, covering an area of 1,404.2m2, is located in a medicine shops, near Chau
Giang river banks, in Hoa Mac DT. Part of the WTP is residential land with existing households, the
rest is bare land. Land acquisition for the project, therefore, will create certain impacts on the daily
routines of households residing within the project area. However, if there are appropriate
compensation policy, this impacts will becomes minor ones.
Production Well Gl, G2 and trial wells, lying at interval of 200-250m, are along National Road 38, on
the land of the DT's Secondary School, Provincial Military Station and stadium. The total occupying
area of each well is small (200m2). After construction, some 1 2m2 shall be used for pumping station,
and the rest can be used for planting trees, installing fences, making protection belts, or even return
to the local authority. Thus, impact of land acquisition is negligible also.
The water distribution network is placed along roads/streets, usually oni or very near the sidewalks to
minimize site clearance. No land acquisition is, therefore, needed.
* Regarding Dong Van DT
The proposed WTP site is in adjacent to power plant, near river sides, provincial road 38 in Dong
Van DT. The entire WTP's area, which cover 1404.2m2, is agricultural land (rice), there shall be
certain impact on the households whose land is occupied by the project. However, if a proper
compensation plan is designed and applied, this impacts will become minor.
Well Gl, G2 and trial drilled well are along Provincial Road 60A and channel banks in paddy field of
Duy Minh comimlune. The interval among wells is 200-250m. The total area of well is small (300 M2)
After construction, some 12m2 shall be used for pumping station, and the rest can be used for
planting trees, installing fences, making protection belts, or even return to the local authority. Thus,
impact of land acquisition is negligible also.
The water distribution network is placed along roads/streets, usually on or very near the sidewalks to
minimize site clearance.
* Regarding Vinh Tru DT
The WTP and intake work are located in a land area adjacent to river sides, which is now used for
growing maize with area of 1404.2m2. Land acquisition anticipatedly exert influences on a number of
households. However, given the smiall acquisition area, these impacts are also minor.
l I~~~~~~~~~~~~~~~~I
fI�"7��rt)t���temu� i ir frt 76n fAr,tk Astibpro.reh
I__The water distribution network is placed along roads/streets, usually on or very near the sidewalks to
minimize site clearance. The impact is therefore, minor and temporary
In short: Since the land acquired for construction of the project components (WTP, Network, wells
and surfacewater intakes) is small, the impacts on the environimeilt is minor.
2. Destruction of Vegetation Cover.
The land used for subproject constr-uctioni comprises miainly 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.

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 miniimize impacts on the soil environment, air emissionl and noise during construction
time, the following mitigation options shall be applied:
U - Mitiqation of PM
Restriction of generated particle matters during construction time: minimizing PM generation by
sprinkling, step-by-step construction, installation of temporary fences around the construction area,
well construction management and supervisioni.
- Control and Mitiqation of Exhaust Gases
| * Do not use old machines (not registered and permitted 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.
| I| - Control and Mitiqation of Noise
3 | " 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 requiremnents, there must be permission of local authority.
* Do not use old machines and equ-ipimient, as the generated noise shall likely be higher than
allowable level. The noise insult shall be maintaineld regularly.
iI
* 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.
| - Labor Safetv
All woikeers on the conistr uctionl site shall be trained on safety regulations and labor rules.
111.2.2 Impacts on inundation, hyc1geo gcpal regimes
I During constiuctioni of conducting and distribution Network, there shall be inevitable impacts on the
existing wastewater drains along roads, pal-ticularly 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 Congestion and lHarrn to Infrastructure.
The supply pipelines for Thai Binh DT has comparatively srnall diameter of 100-150mm, specifically:
l | For Hoa Mac DT: 280m/20,558m
For Dong Van DT: 950m/17,990m
l For Hung Ha DT: 2,050m/20,964m
Supply water pipelines for Ha Nam DT mostly have small diameter (<80mm). Most pipelines are
buried on sidewalks at depth 0.5-0.7m. Excavated earth materials are refilled immediately on the
spot, and no transportation of surplus earth materials is needed. By doing so, no significant impacts
on the environmental are 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 important traffic road (Hoa Mac DT National Road 38: intersection of Road 38 with
I Dong Hoa STr: Dong Van DT: Nguyen Huu Tuyen Str., internal roads of new urban area; Vinh Tru
DT: provincial and communal roads). These influences are inevitable. Construction time shall be in
3 off-peak hours. In sensitive locations, construction 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.
I Surplus waste materials must be collected and disposed off properly. Materials for construction shall
be mobilized to the site just in prior to construction time. Sign boards shall be installed or flag men
provided to instruct traffic.
Construction sometimes necessitates destruction of pavemenit, sidewalks as well as other structures
| where the pipelines cross. In the event of this, proper methods will be proposed in the design to
minimize these impacts. After construction time, the contractors shall coordinate with relevant units
l2U)
to consolidate and restored the distutbed pavements, sidewalks to their initial conditions. Appropliatemeasuir es shall also be taken to reduce the impacts on drainage sewers disturbed by the constructedpipelines. If foundl necessary, temporary drains shall be constructed to ensure normal drainage forthe region.
111.3 Inmpacts during Operation Phase
111.3.1 I creased infiltraflon of rDoIlutuails ilob aciuifers (it) Quyvr)h oi, Hung Ha DT)
Groulndwater (in Hoa Mac and Donq Van DT)
Water extraction from Qb aquifer (Hoa Mac DT) and Qa aquifer( Dong Van DT) may createdepression cones in aquifers. This will facilitate movement of water from upper aquifers as well assurface courses from channels, ponds, lakes, paddy fields into deeper aquifers through hydrogeological windows. Infiltrating water from upper aquiler and surface courses contain solublepollutants, which can alternate the initial composition.
Most of the wells-area is formerly rice field and dry crop land, thus the infiltrating surface water willlikely take a certain amount of chemical fertilizers, agricultural chemicals, thereby polluting thegroundwater aquifers.
During extraction process, flow of underground courses increases substantially. When flowing acrossarea containing such acids as humic and fulvic, iron in water will react with these acids, creatinghumic acid, sulphur or silica colloids, etc. This will reduce pH value in groundwater, create difficultiesfor treatment of iron later on, and unpleasant smell and odor.
| Extraction also creates depression cones as mentioned above and raise the concentration ofpollutants. Movement of water form other part also increase dissolution of pollutants and lead to theincrease of some substances as As.
Suirface water (Vinh Ttu D T)
Sources of potential surface water pollution during operation phase comprises:
| Domestic and production wastewater of local people residing along Tien Hung river sides, whichis within the protection zones of wellfields of Dong Hurig 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 stimulatepaddy growth. Additionally, 0.5 kglsaolyear of pesticides are used. During fertilizing andpesticide spraying process, residuals shall follow 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)arid mostly absorbed by trees, the residuals amount is very negligibly small.

*Impact on the Ai;- Noise and Vibration
During operation stage, the environmental pollutant sources are mainly form: Treatment of raw
supply water by using alum and other chemicals, noise and vibration from secondary pumping
station, air blower, etc. The noise level is moderate, affecting only direct well operators.
* Imipact on Water Envirotinmelnt
Wastewater from aeration constitutes a source of environmental pollution. This wastewater contain
Ihigh 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 Fe203 and MnO2 residues. Others sediments likes
CaCO3 is negligible.
These sediments shall be dried up, packed and transported to prescribed disposal sites of the DT.
111.3.3 Assessment of Setiementi
As above mentioned, subprojects in Quynh Coi and Hung Ha DT use groundwater for supply.
Normally, there are two options during groLindwater extraction as follow:
Option One: (Scenario 1)
Groundwater is very abundant
Extraction with capacity exceeding allowable levels.
Land subsidence
| ~~~~~Option 2 (Scenario: 2)* Groundwater is not abundant
I~~~~~~~~~~~~~~~~Extrction in various location and exceeding tolerable limit
Interferences creating subsidence.

|~~~~~~~~~~~~~~~~~fwhoieii lose.vowrid foi 76) (Oi,1 Attbpl | |r rh|
Regarding 2 subprojects in Hoa Mac and Dong Van, capacity is reported as:
- Hoa Mac: 800 m3/day
- Dong Van: 1,100 m3/day.
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
I_13.4 Mitigation Measures durina Oneration Phase
Extraction Wells (Hoa Mac and Dong Van DT)
* 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 (Hoa Mac arid Dong Van D7)
Drawdown of water in drilled wells in Thai Binh province can be attributed to the following reasons:
| Exliatisfo of recharge sources
l A number of wells are close to each other
l The extraction volume exceeds the capacity.
* During extracton tme, capacity of extracting wells is reduced due to sedimentaton of residues in water,
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.
| Cleaning up of wells, in case the wells are sealed by materials with grain size bigger than the
Inets or holes on screen pipes, the screen pipes can be cleaned.
| Chernical 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. 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.
I'
Besides raw water, other parameters shall also be monitored such as air, noise, vibration, domesticwastewater, waste sludge and water flow.
V_2 Monitoriand rpoing_of Treated Water Qua_t
Treated water quality shall be monitored regularly at reservoir before flowing secondary pumpingstation to the Network. Water samples will be regularly taken and brought to the laboratory of ThaiBinh PWC for analysis. The main analytical indicators to be determined everyday will include: pH,SS, NO2, NH,1, NO3. Cd, Pb, Cu, Zn, Mn, Fe, Phenol, Coliforn will be analyzed periodically everymonth. Additional samples will be collected in the day if the customers have complains about thewater qtuality.
The quality of raw water and finished waler must be in compliance with the national standard onclean water TCVN 5942-1995 and standard Nol329/2002/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 microciirimatic parameters shall be measured atchemical house every three months
Monitoring of waste sludge shall be executed every 6 month.
V.2.4 Monitoring of Drawdown
For subproject using groundwater s supply sources (Hoa Mac and Dong Van DT), the water table shall besubject to changes during exploitabon process. Therefore it will be necessary to set up a water levelgauge system to monitor alternation of water table and adjust production capacity to ensure water qualityanid capacity durinlg exploitabon process. In this regards, stabc and dynamic water levels will bemonitored monthly at producton wells. Wells are cleaned up once a year.
For subproject using surface water as supply source (Chau Giang river water), a level gauge systemshall be provided next to intaking facilibes to monitor the changes in water level and bmely notfy IrrigafionAgency for proper adjushnent of flow. The water flow may be monitored by visual method everyday at theintake and recorded in the record book by WTP's staffs
V.2.5 Institutional ResrDonsibilitv for Water Monitoring
The agency responsible for monitoring of the quality of raw water and treated water is the WTP incooperation with Ha Nam PWC to monitor the water quality daily and monthly.

d. 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 (conmpr-essed 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
techniical parameters ensuring safety. The aveiage dose of consumiiption 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/1m13. The total amount of chlorine consumed in 1 month will be 1,393 kg.
During the operation process the whole system will be subjected to regular inspection and
monitoring; 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.
f. Safety and Accidents
