What's in Kingston's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Kingston Infrastructure Age
With 62% 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
The median home in Kingston was built in 1987 — a figure that places most of the city's residential stock in the era when lead solder was still standard in copper plumbing. Homes built before 1986 may have lead-soldered joints; those built before 1970 face the additional possibility of lead pipes in the service line itself.
Over half of homes in Kingston were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in Kingston
Given current Kingston valuations, the remediation-to-property-value ratio is low — most homeowners are looking at a proportionally modest share that fits within routine financial planning.
Remediation costs in Kingston are relatively low compared to home values. The $950–$3,200 estimated range is a small fraction of median property value. Home values are 21% above the New Hampshire average.
Kingston: 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.
Reading the local data together produces a single household-level picture for Kingston. The 62% pre-rule housing share — that is, the share of buildings constructed before federal rules removed lead solder from new plumbing — combines with citywide utility readings beyond the regulatory action level. The two indicators run in parallel here. An in-home draw produces the household-specific information that aggregate data cannot, and a certified filter via retailer networks is the standard intervention where confirmed results warrant it.
<strong>1 ZIP code</strong> (100% of the city) exceeds the EPA lead action level of 0.015 mg/L.

Kingston: Flood History & Water Damage Risk
Across the NFIP's long tracking period, Kingston shows 8 claims and 100% of ZIP codes within FEMA-designated flood zones — figures that place it in moderate flood exposure territory. At this level, the water-quality implications of flooding — contaminated wells, stressed treatment intake, distribution backflow — move from theoretical edge cases to genuine periodic risks, particularly during higher-severity events.
Kingston has a moderate flood history with 8 FEMA claims averaging $11,849 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>$1,900</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.
