Future Water Supply for Cape May County
Project Title: NJ200 Future Water Supply for Cape May County
Assess the potable and ecological water supply, and develop of a long term plan to reduce the negative and enhance the positive consequences of groundwater withdrawal for potable water supply and similarly reduce the negative and enhance the positive character of the ecological water supply.
Statement of Problem
Use of the potable and ecological water supply of Cape May County has exceeded the safe yield of the groundwater and surface water in an undesirable number of areas of peninsular Cape May. Depressed water levels and salt-water supply has significantly withdrawal, and anthropogenic contamination of the groundwater supply has significantly reduced the long-term viability of the supply. Reduced stream discharge and wet lands water levels caused by groundwater withdrawals, degraded fresh water quality caused by discharge from upland areas, degraded saltwater quality and interrupted flow caused by tide gates and dams has reduced the long-term viability of the ecological water supply.
Strategy and Approach
The recently completed USGS Water resources reports detail the hydrogeologic framework, past water use, and water quality conditions in the county and model the groundwater supply. In cooperation with the NJDEP, USF&W, National Marine Service, local governments and local stake holders assess the future potable and ecological water supply needs, refurbish existing simulations to evaluate well relocation and alternative withdrawal scenarios.
