Physico Chemical Analysis of Groundwater near Municipal Solid Waste Dump Site and Non Dump Site-A Comparative study around Mayiladuthurai, India
Ground Water samples were collected from five bore wells located near the open dump site around 500 meters from Municipal Solid Waste (MSW) of Mayiladuthurai, Tamilnadu State, India and five samples from five to ten kilometers away from Municipal Solid Waste (non-dump site) of Mayiladuthurai. The samples were collected and sent to the laboratory within six hours for analysis. The physico chemical parameters like Total Solid (TS), Total Dissolved State (TDS), pH, Electrical Conductivity (EC), Biological Oxygen Demand (BOD), and Hardness were studied. During the study, it was determined that TDS ranges from 644 mg/l to 127 mg/l and dump sites come under 371 mg/l to 921 mg/l. Therefore the soil parameters in study area have influenced leachate migration.
The North Xinjiang Water Supply Project is a large and long distance water supply project,of which the construction organization design is quite complicated.Within the construction design,the key technical points are the constructions of a tunnel in weak rock,three kinds of inverted siphons and a large channel in desert,and the plannings of both borrow area and the balance of the earth-rock excavation and fill as well as the construction water supply,etc.In conjunction with the construction of the project,the problems given above are briefly discussed herein.
