Housing & Infrastructure in Wakonda
With 88% 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
For residents trying to assess tap water risk in Wakonda, the median build year of 1900 is the starting context. It signals that a majority of homes were constructed before 1986 — the year federal rules prohibited lead solder in new plumbing — and that a significant share likely predates 1970, when lead pipes were still a common choice for residential service connections. Neither risk tier is rare in this housing inventory.
Over half of homes in Wakonda 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 Wakonda Homeowners
The Wakonda equity share sits above the low tier but short of the range where remediation becomes a heavy financial burden — the cost-to-value ratio is moderate, and deliberate planning is the key practical lever for most homeowners.
Remediation costs are moderate relative to home values in Wakonda. The estimated $950–$2,100 range is manageable for most homeowners but still worth budgeting for. Home values are 35% below the South Dakota average.
Lead Exposure Risk for Children in Wakonda
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.
If 88% of the Wakonda inventory comes from before the federal ban on lead-bearing solder — and if utility samples sit at or near 0.015 mg/L — the gap between citywide averages and one specific faucet becomes a practical concern rather than a theoretical one. That is why one-home reads exist as a separate measurement. A certified filter through retailer networks addresses confirmed exposure where it appears in a household.

What You Can Do in Wakonda
- Test your water at home. City-level data shows averages — your tap may differ. NSF-certified test kits cost $20-40 and give results in days.
- Install a certified water filter. Filters rated for Contaminant 0700 can reduce the most common contaminant found in Wakonda's water.
- Check your home's plumbing. With 88% of homes built before 1986, lead solder is a real possibility.
