In Mecklenburg County, groundwater is used for residential drinking water, irrigation and industrial purposes. Approximately 15% of the residents in Mecklenburg County use groundwater as their primary water supply.

Wells in Mecklenburg County can produce highly variable amounts of groundwater, although the average yield is 30 gallons per minute, and 48% of the wells have a yield of 15 gallons per minute or less. The recharge of the groundwater system is directly dependent on how much precipitation we get.

Groundwater is a reliable option, along with wise resource management, to meet our community's demand for water. Typically, groundwater requires little or no treatment to be used as a water supply. However, there are areas of Mecklenburg County that groundwater has been contaminated and should not be used for drinking water, irrigation or industrial processes.

There are more than 1,300 known soil or groundwater contamination sites in Mecklenburg County. Investigations of the water supply usage around these sites have identified 256 contaminated wells. New wells are not permitted within 1,000 feet of a contamination site unless there is no other source of water. In order to protect the water supply, additional well construction requirements and sampling are required for wells within 1,500 feet of a contamination site.
