Water Quality

What we’re doing to maintain the safety and quality of your drinking water

Gainesville’s drinking water comes from the Floridan aquifer. We test and treat it at the Murphree Water Treatment Plant.

Residential Lead and Copper 

GRU routinely monitors your drinking water in accordance with federal and state laws. We test for lead and copper in customers’ homes every three years. Our historical values for lead and copper are low and have met drinking water standards for 25 years. While these contaminants are not in our source water, they can enter tap water through old, corroding household plumbing materials.
