Water filter service in Ramapo, NY

What is in the water in Ramapo

Ramapo is served by Veolia Water New York, Rockland system .

Source water: A blend, and the ratio moves. About 70 per cent is groundwater from wells spread across Rockland County, and the remaining 30 per cent is surface water from the Lake DeForest and Letchworth reservoirs in the Hackensack River watershed. The Ramapo Valley Wellfield is one of the larger production sources. One utility serves roughly 300,000 people across Ramapo, Clarkstown, Orangetown, Stony Point and Haverstraw, excluding the villages of Nyack, South Nyack and Suffern, which run their own systems. Reported by Veolia Water New York for 2023.

Because the supply is a shifting mix of well water and reservoir water, what arrives at the tap is not constant through the year, and a filter sized against one sample can be under specified for another. The state source water assessment rates both the wells and Lake DeForest as susceptible to microbial and nitrate contamination, which is why the surface portion is filtered and disinfected before distribution. Ask which side of the blend serves your address before choosing between a sediment and carbon stack and something with a disinfection stage.

These figures describe the distribution system. Your own tap can differ, and for lead it very likely does.

We do not yet hold a sourced figure for every field on this page. Where something is missing it is left blank rather than estimated, because an unsourced number here would look like information.

Buildings and plumbing in Ramapo

The utility reports that lead is not present in water leaving its treatment plants and that none of its mains are lead, but lead was once standard for smaller diameter service lines, and it puts the share of customers served by a utility owned lead line or gooseneck at under 6 per cent. Ownership splits at the curb: the utility owns the line from the main to the curb stop and the property owner owns the run from the curb into the house. The state health department hosts the inventory summary for this system, revised in August 2024, and Rockland County publishes its own service line pages alongside it. A gooseneck is the short flexible connector at the main and is easy to miss, so a line recorded as copper can still have a lead fitting at one end.

PFAS in Ramapo

The Rockland system ran for a period under a state health department deferral on New York's PFOA and PFOS maximum contaminant levels, an arrangement under which the department held off enforcement while the utility met agreed treatment deadlines. That deferral ended for Rockland on 25 August 2023, so the system is now held to the 10 parts per trillion standards outright. The utility posts quarterly results for these compounds, which is a better basis for a treatment decision here than the annual report alone.

What this means in practice

• Chlorine and chloramine taste. Confirm with free and total chlorine test strip, plus the utility report for the disinfectant type.
• Lead in drinking water. Confirm with certified laboratory analysis of a first-draw tap sample.
• PFAS. Confirm with certified laboratory analysis using an epa-approved pfas method.

What these figures mean for filter choice

Lead is a plumbing question rather than a supply question in Ramapo, as it is everywhere. What that means practically is that a filter certified under NSF/ANSI 53 for lead at the tap you drink from sits downstream of the entire problem, whereas a whole-house filter at the point of entry sits upstream of nearly all of it and costs several times more.

Filters that apply here

• Lead reduction filters. Point-of-use filters certified for lead under NSF/ANSI 53.
• PFAS reduction systems. Reverse osmosis or a certified activated carbon system aimed at per- and polyfluoroalkyl substances.
• Under-sink carbon filters. A carbon block cartridge on the cold line under the sink.
• Reverse osmosis, tank. A membrane system under the sink that produces treated water to a dedicated tap and stores it in a small pressure tank.
• Whole-house filtration. A filter plumbed into the main line where water enters the building, so every tap, shower, and appliance downstream is fed treated water.

Installation in Ramapo

• Free water testing. Typically 45 to 60 minutes.
• Whole-house filter installation. Typically 3 to 5 hours.
• Under-sink reverse osmosis installation. Typically 2 to 4 hours.
• Repair, any brand. Typically 1 to 3 hours.
