Housing & Infrastructure in Marshall
With 65% 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
Federal plumbing rules changed in two stages - lead pipes were phased out before 1970, and lead solder was banned in 1986 - but in Marshall, where the median build year is 1974, most of the housing was already in place before those rules took effect. The materials installed under older standards remain embedded in a substantial portion of the residential inventory today.
Over half of homes in Marshall 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 Marshall Homeowners
Is remediation financially manageable for Marshall homeowners? At a moderate equity share, generally yes - with deliberate budgeting ahead of time.
Remediation costs are moderate relative to home values in Marshall. The estimated $300–$1,500 range is manageable for most homeowners but still worth budgeting for. Home values are 65% below the Oklahoma average.
Lead Exposure Risk for Children in Marshall
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 65% of local housing was built before solder rules changed - as is the case in Marshall - a faucet-level sample closes the gap that aggregate utility data cannot.
