How Old Is Rock Springs's Housing Stock?
With 71% 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
Because the majority of Rock Springs's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1961 reflects a city where lead-era plumbing materials are common rather than exceptional.
Over half of homes in Rock Springs were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Rock Springs: Remediation Cost in Perspective
The equity impact of remediation in Rock Springs sits at a moderate level — real enough to plan for, within reach for most.

Protecting Children from Lead in Rock Springs
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.
Even where utility-side monitoring meets Lead and Copper Rule requirements, the 71% pre-rule share in Rock Springs keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.

Climate-Related Water Risk for Rock Springs
