Housing & Infrastructure in Colome
With 75% 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.

Housing Age Profile
Two dates define the high-risk tiers of residential plumbing from a lead standpoint: 1970, before which lead pipes were commonly installed for service connections, and 1986, before which lead solder was standard in copper plumbing. A median build year of 1977 places Colome's housing distribution well within that older risk zone. The bar chart above breaks down how much of the stock falls into each era — and the pre-1986 share alone represents more than half the residential inventory, making plumbing-era risk a defining characteristic of the local water safety picture.
Over half of homes in Colome 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 Colome Homeowners
Within the Colome market, documented remediation claims a significant slice of typical equity — the financial weight here is material.
At 6.4% of home value, remediation costs in Colome represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $3,150–$7,400. Home values here are 53% below the South Dakota average.
Lead Exposure Risk for Children in Colome
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.
Wherever 75% of local housing was built before solder rules changed — as is the case in Colome — a faucet-level sample closes the gap that aggregate utility data cannot.

What You Can Do in Colome
- Test your water at home. City-level data shows averages — your tap may differ. Lead testing is especially recommended given the area's lead levels.
- Install a certified water filter. Filters rated for Lead can reduce the most common contaminant found in Colome's water.
- Check your home's plumbing. With 75% of homes built before 1986, lead solder is a real possibility.
- Review your water system's CCR. Your utility publishes an annual Consumer Confidence Report with detailed test results. Request it or find it online.
