Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Housing & Infrastructure in Broomfield
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
If your home in Broomfield predates 1986, testing the tap is the direct way to learn about lead; the median build year of 1999 cannot answer that for you.
Most homes in Broomfield were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Broomfield Homeowners
Here the gap between local home values and the estimated repair bill is wide, so the percentage shown below for Broomfield stays at or under the 1% mark.
Estimated remediation costs in Broomfield can be compared with local home values. The $300–$1,167 estimated range can be set against the median property value; actual costs vary by home. Home values are 26% above the Colorado average.
Lead Exposure Risk for Children in Broomfield
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.
Averaged across Broomfield ZIP codes, the 90th-percentile lead results reported by water systems come to less than 10 parts per billion. That is an area summary rather than a reading from any home, and EPA's health goal for lead in drinking water is zero; about 29% of local housing predates 1986.

Historical NFIP Claim Context in Broomfield
Historical NFIP data for Broomfield contains 32 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $16,004. Among ZIP codes with claim records, 33% 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 $567 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 Broomfield
- 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 Surface Water Treatment Rule, listed in the water-quality records for Broomfield: 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.
