What's in Saint Marys's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Saint Marys Infrastructure Age
With 79% of homes built before 1986, lead solder in plumbing is a potential concern. Federal law banned lead solder in drinking-water plumbing in 1986, but many older homes retain original plumbing.

Housing Age Profile
Ask the water utility whether your address in Saint Marys has a lead service line; its inventory can answer what a median build year of 1968 cannot.
Over half of homes in Saint Marys were built before 1986, when federal law began restricting lead solder in drinking-water plumbing. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Saint Marys: Lead Risk & Vulnerable Populations
Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
If you have young children or are pregnant, consider testing your home's water - especially if your home was built before 1986.
