Hydraulic fracturing, a process where a mixture of water, sand and chemicals are pumped underground under high pressure, could be polluting nearby surface water sources through five different ways, according to a Stony Brook University study.
The study found water could be contaminated by transportation spills, well casing leaks, leaks through fractured rock, drilling site surface discharge and wastewater disposal. The greatest contamination risks came from wastewater disposal.
“The used hydraulic fracturing fluid is transported to a wastewater treatment facility and discharged to streams,” according to the report. The researchers said those treatment facilities may not be equipped to handle the chemicals found in the used fracking wasterwater, leading to contaminated drinking water if it is released into nearby water sources, according to the report.
The report largely mirrors findings from ProPublica, which found that these are already leaking.
