Public-record summary
Record-only indicator — incomplete or old records can produce a high score. A score of 100 is not a safety finding. Coverage: 3/3 mapped systems have a dated lead result; 0/3 have copper results; 2/3 have UCMR monitoring. Tap water quality in Saunderstown, Rhode Island (02874) receives an record-only indicator of B (Moderate-low record-based concern) with a score of 76 out of 100, based on analysis of EPA compliance data, contaminant testing, and violation history. This is 6 points below the Rhode Island state average of 82. The area is served by 3 water systems providing water to approximately 27,732 people, using groundwater sources. Notably, 2 PFAS compounds exceed the EPA final MCL value used for comparison — a significant concern given the persistent nature of these chemicals. Over the past 5 years, water systems here have accumulated 73 violations, including 4 health-based violations.
Grade B summarizes the records available to this model, not household safety. Missing, bounded or old measurements can produce a high score, including 100. Review coverage, dates and the current utility report before interpreting this indicator.
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
The record-only indicator is B (76/100). It cannot determine whether your tap water is safe. Missing, bounded or old measurements can produce a high score. Check the coverage and sampling dates below and your utility's current notices.
ZIP code 02874 is served by 3 water systems using groundwater sources, providing water to approximately 27,732 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.
The largest reported lead value or bound is 3.2 ppb, for the sampling period ending 12/31/2024. This is a system-level 90th-percentile record, not a measurement at your tap. Compare the sampling date and original utility report before interpreting it.
Yes — 6 PFAS compounds were detected in records associated with water serving Saunderstown, Rhode Island, 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 Saunderstown, Rhode Island have received 73 violations in the last 5 years, including 4 health-based violations. 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.
This public-record indicator cannot select household treatment. Confirm your supplier, current utility report and tap-testing results first; match any treatment to a certified contaminant-reduction claim and follow its maintenance instructions.
