What's in Milliken's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Milliken Infrastructure Age
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Whether your home in Milliken was built before or after 1986 matters more than the citywide median of 2006, because the 1986 federal lead restrictions cover plumbing installed after that point.
Most homes in Milliken were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

How Remediation Costs Compare in Milliken
Of the three cost-context tiers - low, moderate and elevated - Milliken is in the low one.
Estimated remediation costs in Milliken can be compared with local home values. The $450–$1,400 estimated range can be set against the median property value; actual costs vary by home. Home values are 11% below the Colorado average.
Milliken: Lead Risk & Vulnerable Populations
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.
Pre-1986 construction accounts for about 13% of Milliken homes; older plumbing in any of them can still add lead at the tap.
Sources: EPA Lead and Copper Rule, U.S. Census Bureau ACS, CDC childhood lead poisoning prevention guidelines.
Milliken: NFIP Claim Records and Water-Quality Context
Historical NFIP data for Milliken contains 9 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $50,553. 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 $800 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.

What You Can Do in Milliken
- Test your water at home. City-level data shows averages - your tap may differ. Check the certification, price and turnaround time of any water test kit or lab service.
- Install a certified water filter. For Chlorite, listed in the water-quality records for Milliken: if it is a rule or reporting requirement rather than a contaminant, ask your utility what the record involved; for bacteria, follow any boil-water notice from your utility; for a specific chemical contaminant, check whether a filter is certified to reduce it. Not every contaminant has a consumer filter certification.
- Check your home's plumbing. Homes built before 1986 may have lead solder in pipes. A licensed plumber can assess your risk.
- Review your water system's CCR. If you use a community water system, request its annual Consumer Confidence Report for system-level test results or find it online.
