Key Contaminants Detected in Hanna

How Old Is Hanna's Housing Stock?
With 45% 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
When a home in Hanna was built matters for lead because federal rules adopted in 1986 limited how much lead new plumbing could contain; the local median build year is 1999. A median sits in the middle of a range, so some homes are older and some newer, and past repairs may have changed the pipes in either group. A plumber can identify the materials inside a home, and a lab test measures what reaches the tap.
Most homes in Hanna were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Protecting Children from Lead in Hanna
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.
