Volatile organic constituents have been shown to be present in ,fracturing fluid flowback, wastes at levels that exceed drinking water standards. For example, testing of ,flowback, samples from Texas have revealed concentrations of 1,2-Dichloroethane at 1,580 ppb, which is more than 316 times EPA’s Maximum Contaminant Level for 1,2-Dichloroethane in drinking water .
