What is the main purpose of the Ground Water Rule (GWR)?

The main purpose of the Ground Water Rule (GWR) is to protect against waterborne microorganisms. This regulation, established by the Environmental Protection Agency (EPA), focuses on safeguarding public health by ensuring that groundwater systems are effectively monitored and treated to manage risks from pathogens. The GWR recognizes that groundwater can be vulnerable to contamination from various sources, including inadequately designed or maintained wells and a lack of proper disinfection practices. By setting standards for monitoring and best management practices, the GWR aims to prevent diseases that can be transmitted through contaminated drinking water, thereby ensuring the safety of the water supply for communities relying on groundwater sources.

While reducing chemical usage, ensuring efficient water distribution, and increasing access to well water all relate to water management, they do not capture the primary focus of the GWR, which is specifically aimed at controlling microbial risks in groundwater systems.
