What's in Greenwood's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Greenwood Infrastructure Age
With 42% 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
Roughly balanced between older and newer construction, Greenwood shows a median build year of 1997 — a mid-range figure that places meaningful amounts of the residential inventory on both sides of the 1986 federal plumbing-solder ban.
Most homes in Greenwood were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Greenwood
Equity impact data for Greenwood lands in the favorable tier — remediation claims a small slice of what properties here are worth.
Remediation costs in Greenwood are relatively low compared to home values. The $950–$2,400 estimated range is a small fraction of median property value. Home values are 23% below the Delaware average.
Greenwood: 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.
42% — that captures the slice of Greenwood housing dating from before the federal ban on solder containing lead. It pairs with aggregate utility readings that either approach or cross 0.015 mg/L, the benchmark set under the EPA Lead and Copper Rule. Together, the two figures shift one-home reads into a standard household-level confirmation, particularly for families with kids. A certified lead-removal filter is available through retailer-verified channels if a kit returns results that warrant additional measures.

Greenwood: Flood History & Water Damage Risk
The NFIP claim record for Greenwood — 19 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.
Greenwood has a moderate flood history with 19 FEMA claims averaging $7,126 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>$1,500</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.
