How Old Is Elkton's Housing Stock?
With 67% 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
Reading the housing age data for Elkton — median build year 1979 — the overriding implication is that the plumbing materials inside a typical home here reflect pre-1986 construction standards. In practical terms, that means lead-soldered copper joints are common across much of the housing stock. Where those materials are present, water can leach lead as it moves through joints — a pathway that corrosion control treatment under federal rules is designed to reduce, though it cannot eliminate lead risk where the plumbing materials themselves contain lead.
Over half of homes in Elkton were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Elkton: Remediation Cost in Perspective
Within the Elkton market, estimated remediation claims a small portion of typical property equity — the financial burden is proportionally low.
Remediation costs in Elkton are relatively low compared to home values. The $800–$1,500 estimated range is a small fraction of median property value. Home values are 17% above the South Dakota average.
Protecting Children from Lead in Elkton
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.
Pulling a tap sample fills the gap that utility data cannot close, particularly here where 67% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Elkton.
