Housing Age Profile
What does a median build year of 1900 mean for water safety in Pierpont? It means the majority of the city's residential plumbing was installed before 1986, when lead solder was federally banned, and a large share may predate 1970, when lead pipes were commonly used - making plumbing age a central variable in household-level lead risk across much of the city.
Over half of homes in Pierpont were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Pierpont: Remediation Cost in Perspective
Although the Pierpont remediation share is moderate, it remains reachable for most homeowners who plan for the expense in advance.
Remediation costs are moderate relative to home values in Pierpont. The estimated $800–$1,500 range is manageable for most homeowners but still worth budgeting for. Home values are 41% below the South Dakota average.
Protecting Children from Lead in Pierpont
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.
If 90% of the Pierpont inventory comes from before the federal ban on lead-bearing solder - and if utility samples sit at or near 0.015 mg/L - the gap between citywide averages and one specific faucet becomes a practical concern rather than a theoretical one. That is why one-home reads exist as a separate measurement. A certified filter through retailer networks addresses confirmed exposure where it appears in a household.
