How Old Is Hammond's Housing Stock?
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
A post-1986 majority in Hammond's housing inventory — median build year 2004 — generally signals lower aggregate plumbing-era lead risk.
Most homes in Hammond were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Protecting Children from Lead in Hammond
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Although citywide aggregate readings pass cleanly and just 16% of Hammond housing comes from the pre-rule era, the difference between what utilities sample and what arrives at one specific faucet remains a structural feature of how monitoring works. Households with kids in the home can find a certified lead-removal filter and a draw-test kit through retailer-verified channels. That step is independent of system-level data.
