Throughout South Glastonbury and across its water systems, EPA compliance data for CT shows above-average performance - violations are minimal, none of the tracked systems have recorded repeated MCL exceedances in recent cycles, and the safety picture has held steady across multiple reporting periods.

Data: EPA SDWIS

PFAS MCL Screen	UCMR 5 testing against the covered federal MCLs
Radon Risk	EPA radon zone classification
Annual AQI	EPA AirData county-year median with at least 90 observed days

Housing Age Profile

What does a median build year of 1987 mean for water safety in South Glastonbury? 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.

Pre-1970 (Lead Pipes Risk)

Pre-1970 (29%) 1970–1986 (29%) Post-1986 (42%)

Over half of homes in South Glastonbury 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 South Glastonbury Homeowners

Setting South Glastonbury remediation figures against its property market, the resulting ratio sits comfortably in the low tier - a classification that reflects the kind of household financial position where most homeowners can identify documented issues, schedule the work, and absorb the cost without it registering as a significant budget disruption.

Median Home Value

$528,600

Est. Remediation

$1,600

Remediation as % of home value 0.3%

Remediation costs in South Glastonbury are relatively low compared to home values. The $800–$2,600 estimated range is a small fraction of median property value. Home values are 29% above the Connecticut average.

Lead Exposure Risk for Children in South Glastonbury

58%

Homes Built Before 1986

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.

Practically, the structural drivers in South Glastonbury - 58% pre-rule stock and citywide monitoring at or beyond the regulatory benchmark - make an in-home draw the practical way to translate aggregate averages into the specific conditions at one address.

Avg Reported Sum With Payment Data

100%

A/V Share of Claim-Record ZIPs

Historical NFIP data for South Glastonbury contains 13 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $4,811. Among ZIP codes with claim records, 100% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.

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. The <strong>$1,600</strong> remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.

Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.
