What's in Pasadena's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Pasadena Infrastructure Age
With 58% 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
Lead solder was standard in copper plumbing until federally banned in 1986; lead pipes were common in service lines pre-1970. Pasadena's median build year of 1979 reflects a housing stock where these older materials are a pervasive feature — not a rare legacy — of the residential plumbing landscape.
Over half of homes in Pasadena 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 Pasadena
The equity-to-remediation ratio in Pasadena is moderate — worth planning for but within reach for most property owners.
Remediation costs are moderate relative to home values in Pasadena. The estimated $1,400–$2,938 range is manageable for most homeowners but still worth budgeting for. Home values are 28% below the Texas average.
Pasadena: 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.
After the federal action removing lead-bearing solder from new plumbing took effect, building practice shifted — but 58% of the Pasadena inventory predates that line. With aggregate samples near or beyond 0.015 mg/L, an in-home check moves out of the optional column into the standard list.

Pasadena: Flood History & Water Damage Risk
What does a high NFIP claim count mean for water quality in Pasadena? The 6810 documented claims reflect a flood history frequent enough that those infrastructure degradation pathways — treatment overload, well infiltration, backflow — have almost certainly been periodically activated. That record makes flood timing a relevant factor in local water quality assessment, particularly in the 100% of ZIP codes FEMA has designated as flood zones.
Pasadena has a significant flood history with 6,810 FEMA flood insurance claims on record, averaging $22,775 per claim. With 100% of ZIP codes in FEMA-designated flood zones, flood risk is a major concern for homeowners and water quality.
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. Flood damage can add significantly to the estimated <strong>$2,100</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
