Sizing Up Our Seismic Activity

Think 1 Comment 270

At least 27 mild earthquakes have struck near Azle since Nov. 1, according to the U.S. Geological Survey. We’ll talk this hour about the effects the quakes have had on the community and whether they are related to the booming local oil and gas business. We’ll be joined by SMU seismologist Brian Stump, who is studying the recent seismic activity in North Texas, and Pulitzer Prize-winning reporter Lisa Song of Inside Climate News.

    Thank you for covering the threats posed by the fracking activity. One more activity that presents two more threats to Texans is the 24/7 mining and processing of sand used for fracking. The threats are the silica (sand) introduced into the air and the huge volumes of water used to process the sand. A new sand mine and plant was just approved by the TCEQ in the northwest corner of Cooke county. Some of the largest sources of pollution were ignored by the TCEQ. These were the blowing silica from the mine and the silica in the water used to process the sand. The employees of the plant will not be wearing any filtering devices which will expose them to fine silica, a known carcinogen.

    The plant application confirms that 5 million gallons of water will be used daily to process the sand. As that water is, say, 50% recycled it accumulates more fine (dangerous) silica and most of the new water, say, 2.5 million gallons of water will come from the Trinity and other aquifers–EVERY DAY! A huge amount of additional water will come from the close to 30 water wells to spray over the mine area to try to keep the silica from blowing.

    The TCEQ and the Oil companies work closely to open the plants, but they ignore these threats. Ms. Song is to be applauded to for her research into the threats of fracking. She should add the threat of the sand mining and processing operations.
