How Old Is Douglass's Housing Stock?
With 48% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.

Housing Age Profile
Douglass's residential inventory spans multiple construction eras, with the median build year of 1983 landing in a zone where pre- and post-1986 homes are both well represented. That split matters because homes built before 1986 may contain lead-soldered copper joints — a plumbing practice banned that year — while those built before 1970 face the additional possibility of lead pipes in the service line. Whether a specific household sits on the older or newer end of this distribution is the primary variable shaping its individual exposure risk.
Most homes in Douglass were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Protecting Children from Lead in Douglass
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.
Households with kids in the home — for whom CDC guidance places particular weight on minimizing exposure — face a specific local picture in Douglass. 48% of homes here come from the pre-rule era, and aggregate utility samples either approach or cross 0.015 mg/L. A baseline draw-test kit and certified lead-removal filtration are available via retailer networks for households confirming conditions at a specific tap.
