1. Beaches plagued by bacterial and nutrient pollution
Long Island Sound beaches are experiencing elevated fecal bacteria levels—especially after storms—in places like Suffolk West, where wet-weather failures rose from 8.7% (2020–22) to 12.1% (2022–24)
Windmill Beach in Sag Harbor consistently ranks among the worst hotspots for bacterial contamination.
Public advisories have been common; beaches across Nassau and Suffolk counties have closed due to E. coli and other pathogens.
2. Behind-the-scenes contamination: groundwater and "forever chemicals"
Long Island’s sole-source aquifer has been tainted by decades of industrial pollution—including VOCs, PFAS (“forever chemicals”), TCE, PCE, and 1,4‑dioxane.
Nassau County wells have recorded some of the highest national detections of 1,4‑dioxane, with places like Hicksville logging levels 30–100× above safe thresholds.
PFAS contamination affects countless water districts, prompting lawsuits and controversy—solutions may be delayed if EPA standards roll back.
3. Microplastics and nutrient runoff
Researchers have found microplastic hotspots in local waters, raising concerns about chemical and particulate pollution.
Nitrogen runoff from septic systems, fertilizers, and wastewater has created algal blooms and hypoxic zones—threatening ecosystems and tourism.
🛠️ Solutions by Custom Fabricated Filters
Custom Fabricated Filters (CFF) is a Long Island–based, family-owned company founded by master plumbers Joseph and Noel, offering best-in-class stainless steel filtration systems designed and installed per home .
What sets them apart:
Tailored testing first – CFF provides lab-verified water test kits to pinpoint local contaminants (PFAS, VOCs, bacteria, microplastics), then designs a custom filtration solution.
Stainless steel durability – Unlike disposable plastic filters, CFF systems are built for longevity, reliability, and performance in Long Island's tough water conditions.
Whole-home installations done right – Their trained team ensures seamless fitting and even collaborates with homeowners’ preferred plumbers across Long Island and the NYC metro areas.
Combatting local threats – CFF systems mitigate contaminants like PFAS, 1,4‑dioxane, microplastics, bacteria, and more—helping families and businesses gain peace of mind one tap at a time
Real Impact: One Home at a Time
Suffolk County suburban home: After lab results showed PFAS above federal limits, CFF installed a whole-house system tailored to remove PFAS and microplastics—residents reported noticeably cleaner drinking and shower water within days.
Sag Harbor beach rental: With bacterial advisories frequenting nearby beaches, the owner commissioned a CFF UV‑enhanced filter. Now, guests enjoy safer showers and filtered drinking water year-round.
Suffolk County farmhouse on well water: Faced with VOC and nitrates from old agricultural runoff, CFF installed a stainless-steel multi-stage filter system—ensuring safe, crystal-clear water directly from the tap.
Why This Matters—Especially in Long Island 🌊
With beach contamination rising, preventing in-home exposure is critical—even when shores are closed.
The aquifer is fragile: once contaminants spread underground, remediation is two to three decades and billions of dollars away .
State and county efforts help—but residential filtration fills the gap, equipping homeowners to take water safety into their own hands.
✅ Final Take
Long Island's water crisis—from bacterial beach closures to “forever chemicals” and microplastics—demands action. Custom Fabricated Filters addresses these issues one home at a time with cutting-edge, stainless-steel systems tailored to local threats via thorough testing and professional installation. With CFF in your corner, your tap water becomes a fortress—safe, pure, and reliable.
