Water Quality Summary
Tap water quality in Saint Marys, West Virginia (26170) receives an overall grade of C (Fair) with a score of 57 out of 100, based on analysis of EPA compliance data, contaminant testing, and violation history. This is 10 points below the West Virginia state average of 67. Compared to the national average (75), this area scores significantly lower. The area is served by 3 water systems providing water to approximately 12,951 people, using groundwater sources. Testing has found elevated levels of Lead, Copper that warrant attention. Notably, 2 PFAS compounds exceed EPA limits — a significant concern given the persistent nature of these chemicals. The area has 22 violations over the past 5 years, though none were classified as health-based.
A score of 57/100 indicates fair water quality in Saint Marys, WV. While the water meets minimum federal standards, there are noteworthy concerns — either elevated contaminant levels approaching regulatory limits, a moderate violation history, or both. Residents may want to review specific contaminant data and consider targeted filtration, especially for sensitive groups like children and pregnant women.
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.
Copper can leach into water from copper plumbing, especially in newer homes or when water is acidic.
Short-term exposure above 1,300 ppb can cause gastrointestinal distress. Long-term exposure may cause liver or kidney damage. People with Wilson's disease are especially vulnerable.
Copper pipes, fittings, and faucets are the most common source. Corrosive (low-pH) water accelerates copper leaching.
If copper levels are elevated, flush pipes by running water for 15–30 seconds before use. Reverse osmosis and distillation systems effectively remove copper.
Common Questions
Tap water in Saint Marys, West Virginia receives a grade of C (Fair) with a score of 57/100. While it generally meets minimum federal standards, there are some areas of concern including violation history or elevated contaminant levels. Sensitive populations (children, pregnant women, elderly) may want to consider additional filtration.
ZIP code 26170 is served by 3 water systems using groundwater sources, providing water to approximately 12,951 people. Groundwater is naturally filtered through rock and soil, often requiring less treatment. However, it can be vulnerable to contamination from underground sources like naturally occurring arsenic, nitrates from agriculture, or PFAS from industrial sites.
Lead was detected at 2.9 ppb in Saint Marys, West Virginia. While this is below the EPA action level of 15 ppb, it exceeds the health guideline of 1 ppb recommended by health organizations. Consider a certified lead filter, especially if you have young children.
Yes — 3 PFAS compounds were detected in water serving Saint Marys, West Virginia, and 2 exceed EPA maximum contaminant levels. PFAS are persistent chemicals linked to cancer, immune system effects, and developmental issues. A reverse osmosis or activated carbon filter certified for PFAS removal is recommended.
Water systems serving Saint Marys, West Virginia have received 22 violations in the last 5 years. Violations can range from paperwork issues (monitoring & reporting) to serious health-based violations where contaminant levels exceeded safe limits. Review the violation details above for specifics.
Based on detected contaminants (lead, PFAS, copper), residents in Saint Marys, West Virginia should consider: Reverse osmosis (RO) system — most effective for PFAS, lead, and other contaminants. Always look for filters with NSF/ANSI certification for the specific contaminants you want to remove.
