Housing & Infrastructure in De Smet
With 71% 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
When a city's housing median build year is 1963, as in De Smet, the implication for water quality research is straightforward: municipal-level data captures what leaves the treatment plant, but household plumbing from before 1986 determines what actually arrives at the tap. In cities where older housing predominates, that gap between system-level and household-level data is widest.
Over half of homes in De Smet 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 De Smet Homeowners
How does remediation fit within the broader financial picture for De Smet homeowners? The equity share is moderate - large enough that treating it as a real planning consideration makes sense, and manageable enough that most homeowners have a clear path to addressing documented water and safety issues when they approach the commitment with deliberate advance budgeting rather than as an unplanned expense.
Remediation costs are moderate relative to home values in De Smet. The estimated $1,600–$3,300 range is manageable for most homeowners but still worth budgeting for. Home values are 1% below the South Dakota average.
Lead Exposure Risk for Children in De Smet
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 71% 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 De Smet address.

Historical NFIP Claim Context in De Smet
Historical NFIP data for De Smet contains 7 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $14,280. Among ZIP codes with claim records, 0% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.
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>$2,400</strong> remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.
Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.
