Housing Age Profile
What does a median build year of 1998 mean for water safety in Sparks? It means the housing stock straddles two key plumbing thresholds: the 1986 federal ban on lead solder in copper plumbing, and the pre-1970 era when lead pipes were commonly installed for service lines. A meaningful share of homes predates one or both of those cutoffs, creating varied risk levels across the city's housing inventory.
Most homes in Sparks were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Lead Exposure Risk for Children in Sparks
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 Sparks. 46% 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.
