Housing & Infrastructure in Ellington
With 72% 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
What does a median build year of 1976 mean for water safety in Ellington? It means the majority of the city's residential plumbing was installed before 1986, when lead solder was federally banned, and a large share may predate 1970, when lead pipes were commonly used — making plumbing age a central variable in household-level lead risk across much of the city.
Over half of homes in Ellington were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Ellington Homeowners
Within the Ellington market, documented remediation claims a significant slice of typical equity — the financial weight here is material.

Lead Exposure Risk for Children in Ellington
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.
Before the federal solder ban, lead solder was a routine plumbing material, and 72% of the Ellington inventory was built in that earlier era — a share large enough to move household-level reads onto the standard list.

Flood & Climate Risk in Ellington
FEMA data shows 100% of Ellington's ZIP codes mapped into designated flood zones, paired with an NFIP record of 83 claims. That footprint places local flood exposure in the range where it warrants attention without rising to high-severity planning territory.
Ellington has a moderate flood history with 83 FEMA claims averaging $27,441 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>$2,500</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.
