PACWA’s List of the Harmed Now Mapped by FracTracker

Jenny Lisak, co-director of the Pennsylvania Alliance for Clean Water and Air, maintains a list of people claiming to be harmed by hydraulic fracturing or related processes, called the List of the Harmed.  This version of the list, last updated on February 23, 2013, has 822 people thought to be negatively impacted by the industry, with symptoms ranging from headaches and rashes to death.


The List of the Harmed is maintained by the Pennsylvania Alliance for Clean Water and Air. For full access to map controls, click the “Fullscreen” icon at the top right corner of the map.

The FracTracker Alliance was not involved in the creation or maintenance of this list, but our intern Stephen Paddock did map the incidents to the best available level of accuracy, whether that was at the municipal, county, or state level. Please do not assume that the locations on the map are any more accurate than the level indicated in the “Accuracy” column.

Each entry on the List of the Harmed has at least one link to more information about the given incident.  To access those, click on any map icon to bring up the popup box.  Then scroll down to the “Link” section, and click on “More info”.  If there are multiple sources, they will appear under “Link_2” or “Link_3”.

In the picture above, the text “(1 of 11)” in the yellow oval tells us that there are eleven popup boxes stacked on top on one another.  To sort through the records, simply click the arrow button toward the right edge of the yellow oval.

    Take a look at William Huston’s combined map of symptoms with wells. Most pairings are not surprising. Where there is population and wells, there are symptomatic people. But any thoughts on the locations that are not paired as such. In other words, locations without wells but with health reports and then concentrated well regions without any health reports.

    This work is so valuable and appreciated. Putting a face and a name and now a location reference to the problems resulting from this industry is such an eye opener. Excellent job.
