How Old Is Oelrichs's Housing Stock?
With 58% 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.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Oelrichs's housing stock is predominantly older, with a median build year of 1971 that reflects decades of construction before federal plumbing standards were tightened. The 1986 ban on lead solder and the pre-1970 era of lead service lines are both relevant benchmarks here — a significant share of the residential inventory predates one or both of those cutoffs, creating an elevated baseline for plumbing-related lead risk that aggregate water quality data may not fully reflect at the household level.
Over half of homes in Oelrichs were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Oelrichs: Remediation Cost in Perspective
Low proportionality — that's the Oelrichs picture when remediation costs are placed against typical home equity.
Remediation costs in Oelrichs are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 34% below the South Dakota average.
Protecting Children from Lead in Oelrichs
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.
58% of Oelrichs housing dates to the pre-rule era, alongside aggregate readings hovering at the federal action mark — household-level confirmation through a draw-test kit fits the local picture.
