Ground Water Management

Design of a standard septic system.
Proper siting and installation of private wells and septic systems
ensures protection of public health and our water resources.

The Ground Water Management (GWM) Section is responsible for managing and protecting the ground water resources of Baltimore County. GWM handles issues related to drinking water wells, on-site sewage disposal (septic) systems, removal of residential underground storage tanks, and disposal of solid and hazardous wastes.

 

Well Water Testing

Prior to putting any new well into service, the well must be issued a Certificate of Potability (COP) by the Department of Environmental Protection and Sustainability (EPS) after verification that the water supply meets the mandated testing standards required by state regulations (i.e., the water must be analyzed for bacteria, nitrates, turbidity and sand). Once the COP has been issued, the responsibility of maintaining and testing private water supplies is up to the property owner. EPS staff is available to help troubleshoot any water quality concerns that you may have. A list of private laboratories who can assist you with water testing can be found in our list of Certified Water Testing Labs (PDF).
