Housing Age Profile

Homes on the same street in Baltic can differ: one may keep original pre-1986 plumbing while another has been replumbed, so the 1994 median is only a starting point.

Most homes in Baltic were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

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.

How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure.

Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.
