A recent study published in Environmental Science and Technology found “elevated levels of numerous metals and chemical compounds” from 550 groundwater samples collected from private and public supply water wells in Texas. The wells draw their water from aquifers throughout the 5,000 square miles Barnett shale formation of Texas. While the University of Texas Arlington (UTA) study did not directly attribute the contamination from hydraulic fracturing activities taking place in the area, the authors did conclude, “It is more likely that it (fracturing) has had an effect on water quality.[i]

A recent report published in the San Francisco Chronicle, has found that for the past 30 years California state regulators have allowed oil companies to dispose of billions of gallons wastewater into clean groundwater resources. While early tests of drinking wells don’t show any contamination, the Environmental Protection Agency is “threatening to seize control of regulating the waste-injection wells”[i] that the oil companies use to dispose of “produced water” into the aquifers.

Hydraulic Fracking - Is Drinking Water at Risk?
In the December 2014 issue of Water Online a white paper written by an associate professor and a graduate student from the University of Saskatchewan asks the following question about hyrdraulic fracturing or fracking, “Is drinking water at risk?”
There has been significant debate about the environmental impact of fracking, from erosion to earthquakes. The authors of the white paper describe fracking as a “double-edged sword.” On one side, the process permits the extraction of oil and natural gas reserves from low permeable organic shale formations and tight sand beds. On the other side, fracking carries environmental risks, including “groundwater and surface water contamination, land destruction, air pollution, geologic disruption, greenhouse emissions, and radiation.”
The US EPA hosted a technical workshop on analytical chemical methods for hydraulic fracturing on February 25th in Research Triangle Park, NC. The goal of these workshops is to gather together stakeholders, technical experts, and EPA representatives to get updates on the progress of the EPA’s testing with regards to hydraulic fracturing. It also serves as a forum to discuss best testing practices and methodologies for this area. Teledyne Tekmar was privileged to participate as a speaker and participant in the round table panel discussions that coincided with the workshop.

Part of developing new and relevant applications is staying on top of current events, which can mean reading through a lot of news articles. The one topic we run into most often, especially recently here in Ohio, is hydraulic fracturing. Recently, the governor of Ohio announced increased fees for dumping wastewaters associated with hydraulic fracturing from out of state sources. All implications are that these drilling activities will have a national as well as global impact, as evident by this map of the shale gas plays in North America.
Last week, Tekmar presented a poster at the National Environmental Monitoring Conference (NEMC 2012) on dissolved gas analysis in drinking water. Along with the poster sessions, there were also meetings and sessions on a variety of environmental topics. All of the talks were well attended, especially the session devoted to issues surrounding hydraulic fracturing. One issue that was discussed extensively, and that we continue to see, is light hydrocarbon testing and methane migration.
