Housing & Infrastructure in Simpson
With 60% 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 Simpson, where the median build year is 1988, 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 Simpson 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 Simpson Homeowners
In Simpson, documented water and safety issues can be addressed without making a meaningful dent in home equity — the financial proportionality here is favorable, and the commitment fits within standard property planning frameworks.
Remediation costs in Simpson are relatively low compared to home values. The $150–$600 estimated range is a small fraction of median property value. Home values are 12% below the Louisiana average.
Lead Exposure Risk for Children in Simpson
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 60% of local housing was built before solder rules changed — as is the case in Simpson — a faucet-level sample closes the gap that aggregate utility data cannot.
