What's in Port Aransas's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Port Aransas Infrastructure Age
With 43% 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
Reading the housing data for Port Aransas, with a median build year of 1981, 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 Port Aransas were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Port Aransas
Placing remediation in the context of Port Aransas's property market, the equity share is low — most homeowners here are weighing a financial commitment that fits comfortably within routine property planning, far from the threshold where remediation becomes a material equity decision rather than a standard upkeep consideration.
Remediation costs in Port Aransas are relatively low compared to home values. The $1,800–$4,800 estimated range is a small fraction of median property value. Home values are 127% above the Texas average.
Port Aransas: 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.
Wherever 43% of local housing was built before solder rules changed — as is the case in Port Aransas — a faucet-level sample closes the gap that aggregate utility data cannot.

Port Aransas: Flood History & Water Damage Risk
Over the multi-decade span covered by the National Flood Insurance Program, Port Aransas has accumulated 3487 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.
Port Aransas has a significant flood history with 3,487 FEMA flood insurance claims on record, averaging $41,480 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>$2,900</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.
