Top Contaminants in Cedar Glen Water
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Housing & Infrastructure in Cedar Glen
With 69% 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.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Plumbing risk in older housing is tied to the period before 1986, when lead pipes and lead solder were still permitted in new plumbing. Cedar Glen's median build year is 1978, and properties from before that year might still contain lead-bearing joints or pipes. Much of that risk sits inside individual properties, which city-level water quality averages don't capture.
Over half of homes in Cedar Glen 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 Cedar Glen Homeowners
Here the gap between local home values and the estimated repair bill is wide, so the percentage shown below for Cedar Glen stays at or under the 1% mark.

Lead Exposure Risk for Children in Cedar Glen
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.
Families in Cedar Glen have two area figures that point toward testing. ZIP-level 90th-percentile lead results from water systems average higher than 0.015 mg/L, and 69% of homes are older than 1986. Neither one measures a specific home, which a tap test does.
1 ZIP code (100% of the city's ZIP records) is served by a water system whose 90th-percentile lead result exceeds the EPA action level of 0.015 mg/L.

Historical NFIP Claim Context in Cedar Glen
Historical NFIP data for Cedar Glen contains 5 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $13,253. 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 $4,740 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 Cedar Glen
- Test your water at home. City-level data shows averages - your tap may differ. Consider testing your home's tap water for lead, since household plumbing can affect its level.
- Install a certified water filter. For Nitrate, listed in the water-quality records for Cedar Glen: 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. With 69% of homes built before 1986, lead solder is a real possibility.
