Drilling and fracking consume large quantities of fresh water, and they return that water in a highly polluted state. Recovered fracturing fluid, or flowback, contains not only the original additives (some of which are carcinogenic if consumed in raised quantities over time) but also salty subsurface brines as well as minerals brought up from the formation that may include toxic elements such as barium and radium. Despite myriad disposal regulations, the handling and transport of contaminated water, additives, and sludge are inevitably punctuated by mishaps and negligence. Occurrences such as leaking pipes, breached settling ponds, and even intentional and illegal discharge into rivers and streams periodically arouse the ire of residents, regulators, and Anti-endistri aktivis sou liberasyon an nan polyan nan vwa navigab .
Nan basen nan sid Etazini yo, kote lwil oliv ak gaz perçage yo te pratike sou yon gwo echèl pou prèske yon syèk, refè dlo fracking se regilyèman transpòte nan pwi jete ki egziste deja ak ponpe nan fòmasyon fon anba tè . nan nouvo zòn kote sa yo ki pa gen okenn / sa a. wastewater disposal. In most cases, treated wastewater is released into surface waters while still containing contaminants at tolerable levels set by local pollution standards. Environmental activists note that many standards do not even address some of the chemicals present in fracking water. As a result, the release of even treated wastewater that included fracking fluids may be endangering life in Ekosistèm akwatik . an pati an repons a règleman anviwònman an, pwodiktè gaz yo ap devlope divès metòd pou trete ak reutilize flowback soti nan operasyon fracking .
