Groundwater
Groundwater is a vital resource for Mecklenburg County.  The 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. As we actively search for impacts to the groundwater system we will identify new contamination sites. Contamination is localized, not impacting the entire aquifer. Knowing where the groundwater is impacted is essential to protect current and future use of groundwater as a water supply source.

Well yields in Mecklenburg County are highly variable, although the average yield is 30 gallons per minute, 47% of the wells have a yield of 15 gallons per minute or less. The recharge of the groundwater system is directly dependent on precipitation. The current usage of groundwater from the unconfined bedrock rock aquifer continues to be sustainable.

There are more than 1,400 known soil or groundwater contamination sites in Mecklenburg County. Investigations of the water supply usage around these sites have identified 262 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.

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.

The trends shown in the State of the Environment Report are not all based on tests of statistical significance. Data analysis, anecdotal evidence, and best professional judgment have been compiled to represent these trends. The State of the Environment Report takes a snapshot of important environmental indicators in an effort to educate the public while highlighting challenges, successes and the general direction of change for each indicator. For additional information on these indicators and the determination of trends, please follow the links and feel free to contact the appropriate resources.
