What You Should Know About Denmark Water

  • Homes built before 1986: 50% - older plumbing may contain lead solder.
  • Estimated remediation: $500 per household.
  • Health risk index (ZipCheckup composite of CDC data): 14.44.

Overview

We track home safety data for 1 ZIP code in Denmark, Iowa, where no community water system is mapped to its ZIP codes in our data (about 709 residents). The EPA snapshots used for this build directly map water systems to 0 of 1 ZIP codes.

No EPA violation count is attached to the tracked ZIP codes of Denmark in our data (no water system is mapped, or the mapping is held back for review), so violation records are not shown here; the local utility may still have EPA records (search EPA ECHO by system name).

Lead & Copper

  • Lead data: not yet available for Denmark
  • Lead action-level status: not available

Radon Risk

1 of 1 ZIP records with known zones is in EPA Radon Zone 1.

The EPA recommends testing all homes regardless of radon zone. County radon zones cannot replace an in-home radon test.

Likely Pipe Material

With 50% of homes built before 1986, lead solder in plumbing is a potential concern. Federal law banned lead solder in drinking-water plumbing in 1986, but many older homes retain original plumbing.

Housing Age Profile

Ask the water utility whether your address in Denmark has a lead service line; its inventory can answer what a median build year of 1984 cannot.

Over half of homes in Denmark were built before 1986, when federal law began restricting lead solder in drinking-water plumbing. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Denmark Homeowners

How large is the remediation estimate next to home prices in Denmark? Small in relative terms: it amounts to 1% of the median value or less, although the dollar figure below is still an estimate and actual costs vary by property and contractor.

Median Home Value
$194,600
Est. Remediation
$500
Remediation as % of home value 0.3%

Estimated remediation costs in Denmark can be compared with local home values. The $300–$800 estimated range can be set against the median property value; actual costs vary by home. Home values are 18% above the Iowa average.

Lead Exposure Risk for Children in Denmark

50%
Homes Built Before 1986

Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.

If you have young children or are pregnant, consider testing your home's water - especially if your home was built before 1986.
