Top Contaminants in Lindenhurst Water
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Housing & Infrastructure in Lindenhurst
With 91% 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.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
The median home in Lindenhurst was built in 1952 — 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 Lindenhurst 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 Lindenhurst Homeowners
The cost-to-value ratio in Lindenhurst is in the moderate range — neither dismissible nor alarming, but above the threshold where remediation can be treated as incidental. Most homeowners here are weighing a real equity commitment, and the moderate classification reflects that accurately.
Remediation costs are moderate relative to home values in Lindenhurst. The estimated $5,240–$10,580 range is manageable for most homeowners but still worth budgeting for. Home values are 32% above the New York average.
Lead Exposure Risk for Children in Lindenhurst
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.
Wherever 91% of housing comes from before the federal solder ban and citywide samples cross the regulatory action mark — as in Lindenhurst — household kits and a certified filter via retailer networks are the household-level tools.
<strong>1 ZIP code</strong> (100% of the city) exceeds the EPA lead action level of 0.015 mg/L.

Flood & Climate Risk in Lindenhurst
Lindenhurst's flood profile — 4756 NFIP claims over the program's multi-decade period and 100% of ZIP codes within FEMA-designated flood zones — reflects a community where flooding has shaped the local risk landscape in sustained ways. That sustained exposure has specific consequences for water quality that don't apply to lower-exposure areas. Treatment facilities handling intake from flood-saturated watersheds face contaminant loads that can exceed normal filtration capacity. Private wells in FEMA-designated zones face surface infiltration risk during every significant event. Distribution systems in areas that flood repeatedly accumulate backflow stress over time. None of these represent constant threats to water quality, but they are activated by the kinds of events that the NFIP record shows have occurred here, repeatedly, over many years.
Lindenhurst has a significant flood history with 4,756 FEMA flood insurance claims on record, averaging $34,769 per claim. With 100% of ZIP codes in FEMA-designated flood zones, flood risk is a major concern for homeowners and water quality.
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>$7,860</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.
