Housing Age Profile
What does a median build year of 1951 mean for water safety in Holabird? 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 Holabird 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 Holabird Homeowners
In Holabird, property values comfortably outpace what documented remediation typically costs — the equity share is proportionally low.
Remediation costs in Holabird are relatively low compared to home values. The $800–$1,500 estimated range is a small fraction of median property value. Home values are 54% above the South Dakota average.
Lead Exposure Risk for Children in Holabird
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 74% of the Holabird 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.
