Does Long Island have well water?
Public Long Island Water vs. Private Wells
Aquifers – that’s where our Long Island water comes from. Whether a public water supply company provides your water or you have your own private well on your property, our only source of Long Island drinking water comes directly out of our aquifer system located beneath us.
How many aquifers does Long Island have?
Three
3. The Three Major Long Island Aquifers: Nassau and Suffolk counties obtain their drinking water from three major aquifers underlying Long Island which constitute a sole source aquifer. The aquifers are, from the shallowest to the deepest, the Upper Glacial, the Magothy and the Lloyd aquifers.
How deep is the groundwater table beneath Long Island?
Depending on where you are located on long Island the depth to groundwater is different. The total depth of the Long Island Aquifer System is shallowest on the north shore (approximately 600 feet) and deepest along the south shore (approximately 2000 feet).
Does New York have groundwater?
Groundwater Resources of New York
Although bedrock formations are a significant source of groundwater supply, the most productive aquifers in New York are generally located in unconsolidated sediments (e.g., sand and/or gravel deposits).Bedrock aquifers are also an important source of groundwater.
Why is Long Island water so bad?
The most common contaminant of Long Island groundwater is a group of chemicals known as VOCs (volatile organic compounds). These are generally considered carcinogenic and/or toxic chemicals.These chemicals are known for their role as solvents for other industrial chemicals.
Is it safe to drink Long Island tap water?
Is our water safe to drink? Absolutely! The water we deliver to our customers must meet very strict standards established by New York State, and New York State’s water quality standards are among the strictest in the United States.
Where does water come from on Long Island?
Groundwater Aquifers
Long Island’s Only Source of Drinking Water: Groundwater Aquifers. The water that flows from every single spigot in Nassau and Suffolk County comes from groundwater aquifers and nowhere else. These aquifers are ours to protect. Nothing is more important than clean water to drink.
Which County on Long Island pulls water from the Lloyd aquifer?
Suffolk County
Pumping from the Lloyd aquifer in Suffolk County is limited to a few wells on the barrier islands on the south shore and is not considered to be significant.
What Moraine is known as the backbone of Long Island?
Ronkonkoma moraine
The more southerly moraine, known as the Ronkonkoma moraine, forms the “backbone” of Long Island; it runs primarily through the very center of Long Island, roughly coinciding with the length of the Long Island Expressway. The land to the south of this moraine to the South Shore is the outwash plain of the last glacier.
Why does the fresh groundwater rest above the salty ground water under Long Island?
Precipitation enters the groundwater system by infiltration through the porous soil at Long Island’s surface. Due to the porous soil Long Island has an immature stream development, thus a relatively high percentage of wet precipitation reaches the groundwater.
What is underneath Long Island?
The bedrock slopes down to the south and east beneath the rest of Long Island and therefore does not form any significant landforms here. Resting on the bedrock and extending under nearly all of Long Island is a massive wedge of Cretaceous sediments (sands, clays and gravels).
How do I check my groundwater level?
Groundwater level measurement is mostly performed by a submersible pressure transmitter. These hydrostatic level transmitters are small in diameter and directly suspended by their cable into the well, borehole, deep bore well or monitoring well.
How much groundwater is there compared to surface water?
Ninety-eight percent of Earth’s available fresh water is groundwater. It is about 60 times as plentiful as the fresh water found in lakes and streams. Water in the ground travels through pores in soil and rock, and in fractures and weathered areas of bedrock.
What’s in NYC water?
NYC’s water is treated with chlorine, fluoride, orthophosphate, sodium hydroxide, and ultraviolet light which make it safe to drink.
Where does Queens NY get its water?
Queens gets its drinking water from 19 reservoirs and three controlled lakes spread across a nearly 2,000-square- mile watershed. The watershed is not located in New York City, but rather upstate, in portions of the Hudson Valley and Catskill Mountains that are as far as 125 miles north of the City.
Is Long Island polluted?
Case Study: Long Island Sound
The Long Island Sound estuary annually suffers from low dissolved oxygen conditions because of nutrient pollution – from sewage treatment plants, septic systems, atmospheric deposition, fertilizer and animal waste – from New York City, Long Island and Connecticut.
Can you drink Nassau County water?
Bottled water in New York State must meet the same water quality requirements of the New York State Sanitary Code that apply to tap water. Please be sure that the label has been certified by the New York State Health Department for sale. The certification identification is on the label as “NYSHDCERT #000”.
Can you swim in the Long Island Sound?

Lined with sandbars, Ocean Beach is a great place to swim and relax.Hammonasset beach has more than two miles of beach ripe for swimming.
How dirty is Long Island water?
According to a New York Public Interest Research Group analysis of EPA data, Long Island has the most contaminted drinking water in the state. NYPIRG’s Environmental Policy Director Liz Moran says Long Island’s drinking water contains high levels of harmful contaminants like 1,4-dioxane, PFOS and PFOA.
Is there lead in Long Island water?
A recent study by the New York League of Conservation Voters found that schools on Long Island had more lead in their water than other schools across the state, but the levels are considered safe. Federal guidelines allow a maximum of 15 parts per billion.
