Tap water quality in Riverton, Wyoming (82501) receives an overall grade of F (Failing) with a score of 33 out of 100, based on analysis of EPA compliance data, contaminant testing, and violation history. This is 40 points below the Wyoming state average of 74. Compared to the national average (75), this area scores significantly lower. The area is served by 5 water systems providing water to approximately 10,983 people, using surface water and groundwater sources. Testing has found elevated levels of Lead that warrant attention. Notably, 2 PFAS compounds exceed EPA limits — a significant concern given the persistent nature of these chemicals. Over the past 5 years, water systems here have accumulated 20 violations, including 7 health-based violations.
A score of 33/100 indicates serious water quality failures in Riverton, WY. The water system has significant violations, contaminant exceedances, or enforcement actions. Residents should strongly consider using a certified water filtration system for drinking and cooking water, requesting their utility's latest test results, and potentially having their water independently tested.
Health Information
Lead is a toxic metal that can leach from aging pipes and plumbing fixtures.
Even low levels of lead exposure can cause developmental delays in children, kidney damage, and cardiovascular effects in adults. The EPA action level is 15 ppb, but health experts recommend no safe level of lead in drinking water.
Lead enters water primarily through corrosion of lead service lines, lead solder, and brass fixtures — especially in homes built before 1986.
If lead is detected above 1 ppb, consider using a certified lead-removal filter (NSF/ANSI 53) for drinking and cooking water. Run cold water for 30 seconds before use if water has been sitting in pipes.
