What's in Danville's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Danville Infrastructure Age
With 78% 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 1964, as in Danville, 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 Danville were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in Danville
The equity-to-remediation ratio in Danville is moderate — worth planning for but within reach for most property owners.
Remediation costs are moderate relative to home values in Danville. The estimated $1,250–$2,900 range is manageable for most homeowners but still worth budgeting for. Home values are 13% above the Iowa average.
Danville: Lead Risk & Vulnerable Populations
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.
After the federal action removing lead-bearing solder from new plumbing took effect, building practice shifted — but 78% of the Danville inventory predates that line. With aggregate samples near or beyond 0.015 mg/L, an in-home check moves out of the optional column into the standard list.

What You Can Do in Danville
- 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 Haloacetic Acids (HAA5) can reduce the most common contaminant found in Danville's water.
- Check your home's plumbing. With 78% of homes built before 1986, lead solder is a real possibility.
