5. GROUNDWATER MODELING WITH SEAWAT To assess the impact of GCC and SLR on the groundwater resource under study, a variable density groundwater flow model with GMS SEAWAT package was built on the basis of well-log of 34 boreholes previously drilled inside and surrounding the modeled area. This model consists…
3. CLIMATE CHANGE AND SEAWATER LEVEL RISE TREND The daily monitoring data of Dong Ha and Cua Viet Stations shows indication of global climate warming in the study area: in the last 30 years the daily mean temperature increases 0.5oC, the daily highest temperature increases 0.4 oC, and sea level rises…
4. IN-SITU REMOVAL OF ARSENIC Arsenic contamination of groundwater poses serious health threats and mitigation of this contamination is of high importance in affected regions. The World Health Organisation has set 0.01 mg/L as limit value for arsenic in drinking water, which has also been taken up by Vietnamese drinking…
2.5 Limitations In-situ removal can be considered as alternative to conventional techniques without limitations in principle. However, the efficiency of in-situ removal may be affected by certain conditions, such as high content of easily oxidisable materials or iron sulphite in the matrix of the aquifer, oxidisable contents (especially methane) in…
3.2.3 Zone III The purpose of Zone III is to maintain the quantity and quality of groundwater in the mining area. Typically Zone III surrounds Zone I and II, except when the study area is karst developing area. In legal terms, the requirements for activities in Zone III are not as…
- Middle Pleistocene aquifer - on Hanoi aquifer system (qp) The distribution of qp aquifer is very wide and presented in most of the area. Qp aquifer water level is good and is the source for domestic and industrial water supply.The upper layer (qp2) lies inbetween qh aquifer and layer qp1.The primary sediment constituted for this layer is of sedimentary layers below the floor of Vinh…
