A score of 68/100 indicates fair water quality in Prescott, WI. 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.
Common Questions
Tap water in Prescott, Wisconsin receives a grade of C (Fair) with a score of 68/100. 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 54021 is served by 2 water systems using groundwater sources, providing water to approximately 4,433 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 4.0 ppb in Prescott, Wisconsin. 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 — 6 PFAS compounds were detected in water serving Prescott, Wisconsin, 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.
