What's in Davenport's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Davenport Infrastructure Age
With 77% 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.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Because the majority of Davenport's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1947 reflects a city where lead-era plumbing materials are common rather than exceptional.
Over half of homes in Davenport 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 Davenport
Looking at how documented remediation costs fit within Davenport property values, the equity share lands in the moderate tier - a finding that positions the household financial perspective between routine maintenance and a significant budget commitment, where most homeowners can successfully address documented issues by treating the expense as a planned financial priority rather than an unexpected one.
Remediation costs are moderate relative to home values in Davenport. The estimated $1,956–$4,000 range is manageable for most homeowners but still worth budgeting for. Home values are 4% below the Iowa average.
Davenport: 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.
When older housing represents 77% 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 Davenport address.

Davenport: NFIP Claim Records and Water-Quality Context
Historical NFIP data for Davenport contains 1,124 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $21,769. Among ZIP codes with claim records, 100% 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>$2,933</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.
