Over half of homes in Concord 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 Concord Homeowners
At current valuations, Concord sits in the low remediation-share tier — the equity impact of fixing documented issues is proportionally minor.

Lead Exposure Risk for Children in Concord
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.
When older housing represents 89% of the local inventory or aggregate readings approach the federal action level, an in-home check becomes the standard way to translate citywide averages into the specific reality of an individual Concord address.
