Methane Concentrations in Well Water in New York State (report by USGS)

The USGS recently released a study on methane concentrations in well water in New York State. Methane is the main component of natural gas. The study finds that methane commonly occurs naturally in groundwater, sometimes at quite high levels and in areas where it might not be expected. Many of the wells with high levels of methane were far from any natural gas production. The study found that about 2% of the water wells they sampled had methane levels high enough to ignite and another 7% had levels high enough to be of concern. Methane concentrations in well water can be reduced or eliminated by placing a vent on the well to release the methane to the atmosphere before it enters the house.

The complete study is available for review at:
