Housing Age Profile

Most homes in Melba were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Melba Homeowners
When remediation costs are measured against Melba home values, the resulting ratio is in the low tier — addressing documented water and safety issues here claims only a minor fraction of typical equity, and most homeowners are in a position where the financial commitment is straightforward rather than a material burden on their household budget.
Remediation costs in Melba are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 25% above the Idaho average.
Lead Exposure Risk for Children in Melba
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.
Wherever 39% of local housing was built before solder rules changed — as is the case in Melba — a faucet-level sample closes the gap that aggregate utility data cannot.
