Water Quality Summary
Tap water quality in Canandaigua, New York (14424) 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 42 points below the New York state average of 75. Compared to the national average (75), this area scores significantly lower. The area is served by 8 water systems providing water to approximately 40,725 people, using surface water sources. Testing has found elevated levels of Lead, Copper that warrant attention. PFAS testing detected 1 compound, all currently below EPA limits. Over the past 5 years, water systems here have accumulated 69 violations, including 39 health-based violations.
A score of 33/100 indicates serious water quality failures in Canandaigua, NY. 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.
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.
