Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Crosby 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
Reading the housing data for Crosby, with a median build year of 1996, reveals a community where neither old nor new construction dominates. That balanced profile means lead-solder-era plumbing is present throughout a meaningful portion of the residential inventory — with risk concentrated in properties built before 1986 and most acute in those that predate 1970.
Most homes in Crosby were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Crosby
In Crosby, documented water and safety issues can be addressed without making a meaningful dent in home equity — the financial proportionality here is favorable, and the commitment fits within standard property planning frameworks.
Remediation costs in Crosby are relatively low compared to home values. The $1,500–$3,300 estimated range is a small fraction of median property value. Home values are 7% above the Texas average.
Crosby: 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.
Although utility-side compliance with federal Lead and Copper requirements remains the system reference, that compliance does not extend down into interior plumbing. With 39% of Crosby stock built before the solder ban and aggregate readings at or beyond the action mark, a household-level sample becomes the practical way to close that information gap.

Crosby: Flood History & Water Damage Risk
Over the multi-decade span covered by the National Flood Insurance Program, Crosby has accumulated 1155 flood claims — a total that reflects a community where significant flooding is a recurring, documented feature of the local environment. That history has direct relevance to water quality. Each major flood event activates contamination pathways that are absent or dormant during dry conditions: treatment plants handling floodwater-saturated intake face sharply elevated contaminant loads; private wells in low-lying FEMA-designated zones — which cover 100% of local ZIP codes — can be infiltrated by surface runoff carrying bacteria, sediment, and chemical residue; distribution systems under pressure during flooding can experience backflow that draws untreated water into the supply.
Crosby has a significant flood history with 1,155 FEMA flood insurance claims on record, averaging $43,914 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>$2,300</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.
