Lead solder was federally prohibited in new plumbing in 1986. In Gadsden, the median build year of 1991 puts a majority of homes in the lower-risk category for that specific contamination pathway — though the pre-1986 share shown above still carries real exposure potential at the individual household level.

Lead Exposure Risk for Children in Gadsden

mg/L Avg Lead (Limit: 0.015)

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 20% of Gadsden 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.

What You Can Do in Gadsden
