See the record ↓Red Hook (T)'s drinking water received a grade of C+ (69.2 out of 100), indicating fair water quality. The city's 11 water systems serve approximately 611 residents using groundwater.
Lead levels were measured at 6.0 ppb (90th percentile), which is within EPA limits but above recommended levels. This system has not yet been tested for PFAS under the EPA UCMR 5 program. The system has 158 violations on record, including 1 health-based violation. 31 remain unresolved.
Red Hook (T) ranks #698 out of 810 cities in New York for water quality, placing it among the lowest-rated in the state. Red Hook (T) relies on groundwater, which is generally less vulnerable to surface contamination but can be affected by naturally occurring minerals like arsenic and nitrate, as well as agricultural and industrial runoff. While lead levels are within EPA limits, they are above the recommended 5 ppb threshold that health organizations consider ideal. A point-of-use filter adds an extra layer of protection. As a small community water system, Red Hook (T) may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities. The system has seen 6 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
02What's in Red Hook (T)'s water
Every contaminant flagged in Red Hook (T), on one shared scale: distance to its own legal limit. The red line is the limit — anything past it is out of compliance, and the closer a bar gets, the less headroom the system has.
Over Limit — EPA Action Level: 1.3 mg/L
Exceeds the EPA action level. Copper leaches from household plumbing — flush taps for 30 seconds before drinking, and consider a certified filter.Full contaminants report

04Where Red Hook (T)'s water comes from
Red Hook (T)'s drinking water is drawn from underground aquifers through wells.
Ground Water Under Influence
Underground aquifers reached by wells — naturally filtered, but can carry minerals like arsenic and nitrate.
Local treatment
Groundwater generally needs less treatment — typically disinfection and, where needed, mineral removal.
11 systems
11 water systems, operated under local government ownership.
611 people
Residents served across Red Hook (T)'s service area.
Groundwater is naturally filtered through rock and soil layers, generally requiring less treatment than surface water. However, it can contain naturally occurring contaminants like arsenic, radon, and minerals. Agricultural activity, septic systems, and industrial operations near well fields can introduce nitrates, pesticides, and volatile organic compounds. The system is operated by local government ownership and serves approximately 611 people through 11 water systems.

05Pressure on Red Hook (T)'s watershed
Outside forces that shape what reaches the treatment plant. None of these is a verdict on the tap by itself — but each adds pressure worth knowing about.
Drought
Dutchess County is in D1 (moderate drought) per the U.S. Drought Monitor (week of Jul 2026). Drought can raise disinfection-byproduct levels and taste/odor issues as utilities draw from lower reservoirs.

07What to do at home
Steps matched to what testing actually found in Red Hook (T)'s water — not generic advice.
Filter drinking & cooking water
NSF-certified water filter. Lead detected at 6.0 ppb
Compare tested filters →Flush taps & check your service line
Lead leaches from pipes as water sits. Run cold water 30 seconds before drinking (especially mornings), and ask the utility whether your address still has a lead service line.
