What's in Overbrook's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Overbrook Infrastructure Age
With 46% 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.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Lead solder was allowed in new plumbing until the 1986 federal restrictions, which is why older homes in Overbrook deserve a closer look; the median build year is 1983.
Most homes in Overbrook were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Overbrook: 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.
