How Old Is Hill City's Housing Stock?
With 49% 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
Pre-1986 construction carries elevated plumbing-era lead risk because lead solder was widely used before that federal ban. In Hill City, the median build year of 1983 indicates a housing stock where that older fraction represents a significant share of the residential inventory.
Most homes in Hill City were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Hill City: Remediation Cost in Perspective
Given current Hill City valuations, the remediation-to-property-value ratio is low - most homeowners are looking at a proportionally modest share that fits within routine financial planning.
Remediation costs in Hill City are relatively low compared to home values. The $1,200–$3,300 estimated range is a small fraction of median property value. Home values are 85% above the South Dakota average.
Protecting Children from Lead in Hill City
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.
When older housing represents 49% of the local inventory or aggregate readings approach the federal action level, an in-home check becomes the standard way to translate citywide averages into the specific reality of an individual Hill City address.

How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. The <strong>$2,200</strong> remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.
