Top Contaminants in Christiana Water
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Housing & Infrastructure in Christiana
With 69% 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
The character of Christiana's housing stock is one of deep historical layering - a median build year of 1978 signals a city built largely before the plumbing era changes of 1986 and 1970. Lead-soldered copper joints and, in the oldest properties, lead service lines are commonly present in this inventory. That context shapes what individual water testing may reveal, particularly in neighborhoods where the oldest housing is concentrated.
Over half of homes in Christiana were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Christiana Homeowners
Because estimated remediation claims a substantial fraction of typical Christiana property equity, the household financial perspective here requires serious advance planning - the cost-to-value ratio is in the elevated tier and warrants structured preparation.
At 2.5% of home value, remediation costs in Christiana represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $4,910–$10,120. Home values here are 37% above the Pennsylvania average.
Lead Exposure Risk for Children in Christiana
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.
Wherever 69% of housing comes from before the federal solder ban and citywide samples cross the regulatory action mark - as in Christiana - household kits and a certified filter via retailer networks are the household-level tools.
<strong>1 ZIP code</strong> (100% of the city) exceeds the EPA lead action level of 0.015 mg/L.

Historical NFIP Claim Context in Christiana
Historical NFIP data for Christiana contains 22 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $26,445. 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>$7,440</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.
