Housing & Infrastructure in Selby
With 87% 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 1951 places Selby'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 Selby 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 Selby Homeowners
At current valuations, Selby falls in the moderate remediation-share tier - a level where treating this as a budgeted line item rather than an ad-hoc expense is the practical approach.
Remediation costs are moderate relative to home values in Selby. The estimated $800–$1,500 range is manageable for most homeowners but still worth budgeting for. Home values are 32% below the South Dakota average.
Lead Exposure Risk for Children in Selby
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 87% of local housing was built before solder rules changed - as is the case in Selby - a faucet-level sample closes the gap that aggregate utility data cannot.
