Water Quality Summary
Tap water quality in Petersburg, Tennessee (37144) receives an overall grade of B (Moderate-low record-based concern) with a score of 83 out of 100, based on analysis of EPA compliance data, contaminant testing, and violation history. This is 7 points below the Tennessee state average of 90. The area is served by 6 water systems providing water to approximately 24,569 people, using surface water sources. Notably, 2 PFAS compounds exceed the EPA final MCL value used for comparison — a significant concern given the persistent nature of these chemicals. The area has 74 violations over the past 5 years, though none were classified as health-based.
A score of 83/100 means Petersburg, TN performs well in the US Water Score model, with only minor system-level concerns. Residents should still review their utility's Consumer Confidence Report for official compliance information and household-specific context.
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.
Common Questions
Based on public water-system records, Petersburg, Tennessee receives an internal US Water Score grade of B (Moderate-low record-based concern) with a score of 83/100. This indicates relatively few system-level concerns in our model, but it is not an EPA safety rating and does not guarantee tap conditions inside individual homes.
ZIP code 37144 is served by 6 water systems using surface water sources, providing water to approximately 24,569 people. Surface water systems are more susceptible to contamination from agricultural runoff, industrial discharge, and weather events, but typically undergo more extensive treatment including filtration and disinfection.
Lead levels in Petersburg, Tennessee are 1.0 ppb, which is at or below the health guideline of 1 ppb. This is a positive result, though periodic testing is still recommended.
Yes — 7 PFAS compounds were detected in records associated with water serving Petersburg, Tennessee, and 2 results exceeded the numerical EPA MCL value used for comparison. UCMR5 occurrence results alone are not a regulatory compliance determination. PFAS rules and compliance timelines are evolving; verify current information with the utility and EPA.
Water systems serving Petersburg, Tennessee have received 74 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.
