Housing & Infrastructure in Delta
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
Housing age matters for water quality because lead solder was widely used in plumbing until the 1986 federal ban. Delta's median build year of 1993 suggests a majority of homes were constructed under the newer standard — a meaningful factor when assessing household-level lead risk from tap water.
Most homes in Delta were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Lead Exposure Risk for Children in Delta
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.
Confirming what flows from a specific faucet still requires a one-home draw, even where Delta averages stay clean and the pre-rule housing share holds at 28%.

Flood & Climate Risk in Delta
The NFIP claim record for Delta — 7 filed incidents — reflects genuine, recurring flood exposure rather than an isolated event or two. When a community accumulates flood claims at this volume and carries 100% of its ZIP codes inside FEMA-designated zones, flood history starts to factor into water quality planning in ways it doesn't for lower-exposure areas. Flooding introduces specific contamination pathways — runoff overwhelming treatment facility intake, surface water infiltrating private wells, and pressure disruptions in distribution systems allowing backflow — all of which become more relevant as flood frequency increases.
Delta has a moderate flood history with 7 FEMA claims averaging $14,700 per payout. 100% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
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>$1,200</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.
