2025 Assessment
01 — Source & System Overview

Open Reservoir Water.
Chemically Treated. Not Filtered.

The municipal water supplied to 250 Bryant Ave., White Plains, NY 10605 is drawn from the Kensico Reservoir in Valhalla, NY, part of the NYC surface-water system. This is open-air surface reservoir water that is not conventionally filtered prior to distribution.

Treatment relies primarily on chemical disinfection, corrosion control additives, and monitoring — not the physical removal of contaminants. All findings discussed in this report are self-reported by the White Plains Water Department in its annual Water Quality Reports.

"Consumption safety relies on regulatory tolerance, not contaminant removal."

🏞

Kensico Reservoir

Open-air surface water. Exposed to runoff, animal waste, storm events, and seasonal variation.

⚗

Chemical Disinfection

Chlorine added. Orthophosphate (corrosion control) added. No physical filtration stage applied.

🔧

Distribution Network

Water ages in pipes. Disinfection byproducts form and increase. Metals leach from plumbing.

🚨

Your Tap

Arrives at 250 Bryant Ave. with all accumulated contaminants from source to pipe intact.

02 — Identified Contaminants

Structurally Unavoidable.
Even Within Regulatory Limits.

● Critical Risk
Disinfection Byproducts
TTHMs & HAA5 — Formed when chlorine meets organic matter in reservoir water
  • Long-term exposure linked to bladder cancer
  • Linked to adverse reproductive effects
  • Not removed by boiling
  • Present by design in all chlorinated systems
● Elevated Risk
Chlorine Residual
Intentionally maintained throughout distribution to suppress microbial growth
  • Respiratory and skin irritation
  • Reacts in-home to form additional byproducts
  • Degrades plumbing elastomers and filter media
● Critical Risk
Microbial Pathogens
Surface reservoirs inherently exposed to animal waste, runoff, and storm events
  • Protozoa, bacteria, and viral fragments
  • Disinfection reduces — does not eliminate — risk
  • Immunocompromised populations most vulnerable
● Elevated Risk
Turbidity & Particulates
Fine suspended solids and colloids that fluctuate seasonally and after storms
  • Shields microbes from disinfectants
  • Carries adsorbed metals and organic compounds
● Elevated Risk
Heavy Metals & Inorganics
Reported detections: aluminum, manganese, iron, nickel, zinc, barium, copper
  • Neurological and metabolic impacts with chronic exposure
  • Bioaccumulation potential varies by metal
  • Copper leaches from premise plumbing
● Monitor
Orthophosphate Additives
Added intentionally to coat pipes and reduce lead/copper leaching
  • Alters mineral balance in consumed water
  • Contributes to nutrient loading downstream
● Elevated Risk
Nutrients & Salts
Nitrate, sodium, and chloride — often seasonally elevated
  • Cardiovascular relevance for sodium-sensitive individuals
  • Infant risk with nitrate exposure
● Critical Risk
Radioactivity
Gross alpha, beta, and radium monitored and detected at low levels
  • Long-term cancer risk at cumulative exposure levels
  • No safe threshold for ionizing radiation consumption
● Monitor
PFAS & Fluoride
Synthetic fluorinated compounds now detected nationwide in surface waters
  • Persistent — do not break down in environment or body
  • Linked to hormone disruption and immune effects
  • Pass through current dispenser unfiltered
03 — Current Dispenser Assessment

Your Brio Dispenser.
Insufficient as Primary Treatment.

Installed Unit
Brio CLCTPOU620UVF2
Stage 1: Sediment
Stage 2: Carbon Block
UV Chamber
⚠ Critical Gap in Protection
UV does not remove chemicals — it only inactivates certain microbes. The Brio should not be relied upon as the primary treatment device. It should function only as a final dispensing and polishing stage downstream of proper filtration.
What It Can Reduce
✓
Sediment and particulate matter
Chlorine taste and odor
Some volatile organic compounds (VOCs)
Minor particulate load
What Passes Through Unfiltered
✗
Disinfection byproducts (TTHMs, HAA5)
PFAS compounds
Fluoride
Dissolved metals
Nitrates and salts
Radioactive ions
04 — Filtration Solution

From Risk-Reduced
to Genuinely Safe.

Without the following interventions, the water at 250 Bryant Ave. remains unsuitable for routine human consumption. These are not optional upgrades — they are minimum requirements for defensible drinking water safety.

▲ Bare Minimum — Non-Negotiable
3 Inline Filters
Before Your Dispenser
  • PFAS-Rated Adsorptive Media — Addresses synthetic fluorinated compounds now detected in surface waters nationwide. Must be rated and certified for PFAS reduction.
  • High-Capacity Carbon Block — Reduces TTHMs, HAA5, and chlorine load before water reaches the Brio dispenser.
  • Fine Sediment / Particulate Filter — Reduces turbidity-associated contaminant transport and protects downstream media from fouling.
★ Strongly Recommended — Above & Beyond
NSF/ANSI 58
Reverse Osmosis System
  • Broad removal of PFAS, fluoride, nitrates, dissolved metals, radioactive ions, and DBP precursors.
  • Post-RO Carbon Polishing — Restores taste and removes residual organics after the RO membrane.
  • Remineralization Option Available — Re-adds beneficial minerals stripped by RO for balanced drinking water.
  • Brio dispenser then serves as final polishing stage only — its intended role.

Final Assessment
"The science is clear. The disclosures are explicit.
Filtration is not optional if occupant health is the priority."

The municipal water supplied to 250 Bryant Ave. meets regulatory definitions of potable water. Regulatory compliance and drinking water safety are not the same standard. The gap between them is where your family's health lives.
