The surface water and groundwater supplies are treated before entering the distribution system. At the treatment plant, chemicals are added to facilitate removal of contaminants, which are removed in the settling basins before passing through mixed media filters to remove smaller particles. The water is then disinfected with chlorine and introduced to the Town distribution system. The water from Cornwell Well contains iron and manganese. The water is treated with potassium permanganate and sodium hypochlorite to oxidize the iron and manganese, which is subsequently removed through a greensand filter.
Chlorine is added for disinfection.
The water from Main Street Village Wells also contains iron and manganese. The water is treated with potassium permanganate and sodium hypochlorite, which is subsequently removed through a greensand filter. Chlorine is added for disinfection and flouride is added to promote strong teeth before the water is introduced to the distribution system. Under a new program being developed by VDH, a detailed source water assessment will be conducted within the next few years to find ways to better protect our water sources. The tables on the next few pages show the most recent results of our monitoring.
