Housing & Infrastructure in Walsh
With 78% 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
When more than half a city's housing predates the 1986 federal ban on lead solder, plumbing-era lead risk becomes a citywide concern rather than an exception. Walsh's median build year of 1977 places it squarely in that category.
Over half of homes in Walsh were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Walsh Homeowners
Middle of the range — Walsh homeowners face a remediation share that calls for real financial attention without reaching crisis territory.

Lead Exposure Risk for Children in Walsh
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.
Older stock in Walsh represents 78% of the inventory, and citywide monitoring runs at or above the federal action level — making an in-home read a standard household-level step.
