Gas Drilling Complaints Map
The drilling complaints map reflects the results of Pennsylvania Department of Environmental Protection investigations at nearly 1,000 properties where water supply owners suspected oil and gas drilling activities polluted or diminished the flow of water to their wells between 2008 and fall 2012.
Yellow dots mark municipalities where DEP determined drilling-related activities affected water supplies. Pink dots mark places where DEP did not observe a change in water conditions or did not link it to drilling. Purple dots mark sites where DEP's determination was unfinished or unclear at the time regulators reported results to the water supply owner.
Enlarge the map and click on a dot to review all the determinations for the selected municipality including copies of the enforcement orders or letters sent to property owners (with identifying information removed).
The map was developed by The Times-Tribune and The FracTracker Alliance, a non-profit organization that collects, shares and visualizes data related to the oil and gas industry.
