Private water well owners are responsible for their own water quality. Even in the absence of shale-gas drilling, well owners are strongly encouraged to evaluate their water on a regular basis in order to ensure that basic water quality standards are being met. This bulletin offers guidance for landowners and private water well users who seek information on the need, frequency, and thoroughness of testing in the context of shale-gas activity in their area.
Have you ever heard of stable isotopes? Some researchers utilize stable isotope analysis to assess the source of certain groundwater contaminants, such as methane. When used in combination with other tests, such analyses can be helpful in distinguishing between contaminants that may be present in water naturally, and contaminants that may have been introduced through human activity. WRI has developed a document that helps to explain the role of stable isotopes in monitoring groundwater quality.
