Our primary responsibility is to provide clean, safe drinking water to our customers and we take that responsibility very seriously.
water quality experts have been closely following the national study of man-made substances called per- and polyfluoroalkyl substances (PFAS), often associated with fire-fighting foams and other commonly used household and daily use products. In fact, these man-made substances are so common across the United States that independent scientific research suggests almost everyone has had contact with PFAS at some point.
The Environmental Protection Agency's (EPA) Safe Drinking Water Standards are considered the world's gold standard for drinking water safety. While there is no current EPA requirement to treat PFAS substances, the EPA has issued a recommendation that concentrations of two individual PFAS contaminants in drinking water – PFOS and PFOA – not exceed 70 parts per trillion (ppt), combined. To put that into perspective, one part per trillion is the equivalent of a single drop of water in an Olympic-size swimming pool. The EPA has determined that its recommended level provides even the most sensitive populations with a margin of protection from a lifetime of exposure to PFOA and PFOS from drinking water.
We recently received results that, for the first time, indicated an extremely low presence (between 4 and 7 ppt) of PFAS at an entry point to the Clovis drinking water system for several wells.
There is no health concern but we took extra steps just to be on the safe side.

letter to our customers.
PFAS are a family of man-made substances used across a variety of industries since the 1940s. Within the family of PFAS substances, PFOA and PFOS have been the most extensively produced and studied. They don't break down so they can accumulate over time, and studies have shown that exposure to PFAS can be potentially harmful. You can find more information here.
PFAS are often associated with fire-fighting foam, commonly used household items and daily use products, such as stain- and water-repellent fabrics, nonstick products, polishes, waxes, paints and other cleaning products.
