Study: Toxic Fracking Waste is Leaking into California Groundwater

Study: Toxic Fracking Waste is Leaking into California Groundwater

November 30, 2021

California is facing “massive” groundwater contamination due to the practice of dumping wastewater into "percolation pits," being the last state in the US that allows dumping into these unlined ponds.  The amount of water being disposed of this way is increasing rapidly: in 2019, there was nearly 3 billion barrels of produced water generated by the oil/gas sector, or roughly 18 barrels per barrel of oil produced, having more than doubled from the 8bbls per barrel of oil registered 20 years ago.  There are 1,850 produced water ponds in California’s Tulare Basin alone, and to date regulators and corporates have generally concluded that the cost of the clean-up of legacy contamination is excessive - even while the dumping of 16bbls/year into the percolation ponds continues.  These percolation ponds and “spray-fields” allow toxins to either seep into underground aquifers or flow into rivers and aqueducts when it rains.  In one case, the carcinogen benzene was found at 45x the safety limit for drinking water.

Federal Government Releases Seismicity Report Studying Possible Federal Regulations
January 2023
The attached comprehensive report (dated 1/13//23) on human-induced earthquakes from injection wells was prepared for the US Congress. Given the continued rise in the number and severity of these earthquakes, as well as their ability to cross state lines, the US Congress is considering more oversight: a.) amending the UIC program "to require consideration of induced seismicity"; b.) if the “federal government should have a role in regulating underground fluid injection activities"; and, c.) various other possible funding/regulatory options. EcoVAP is helping the oil/gas sector (and others) stay ahead of this increasing state - and possibly now federal - scrutiny by reducing the volume of produced water by over 90% using practically no energy or other operating cost: https://www.ecovap.com/case-studies/oil-gas-operation.
Tailings Pond Volumes Increasing with Lower Grade Ores
January 2023
The world’s 29,000-35,000 active, inactive and abandoned tailings storage facilities (“TSFs”) contain approximately 534 billion cubic meters (~14 trillion gallons) of wastewater. With recent catastrophic failures, there is increasing regulatory scrutiny of TSF safety, but these efforts are challenged by ever-increasing amounts of TSF wastewater due to mining successively lower grades of ore (see article below) and also due to increased weather volatility. Hence, the number of TSF failures is expected to continue to increase. EcoVAP’s proven technology for evaporating this wastewater, thus reducing or practically eliminating the volume of wastewater at any TSF, can help reduce the operational cost and environmental risk of tailings wastewater disposal.
EcoVAP Solution for Coal Power Compliance with Coal Ash Rule
November 2022
In November 2023, the environmental law group Earthjustice released a 212-page report on the difficulties of coal fired thermoelectric plants in complying with the Coal Ash Rule. The new report (an update from the initial 2019 report), estimates that "91% of coal plants are causing unsafe levels of groundwater contamination”, but also highlights many coal-fired power generators that have already or are planning to remedy these problems. With the ability to dewater tailings ponds, EcoVAP has proven its ability to provide a low cost, environmentally friendly means of dramatically remedying this challenge, with one client achieving an 85% reduction in land footprint and a 40% decrease in handling costs (see https://www.ecovap.com/case-studies/thermoelectric-power-plant).
