U.S. EPA and many state agencies are investigating fracking in Marcellus Shale’s impact on environmental water quality. Public outcry has led to drafting legislation. Increased levels of bromide in drinking water systems correlate to higher levels of brominated disinfection byproducts. Trace metals (i.e., arsenic, selenium, lead), important constituents of flowback water, must be accurately determined for regulatory compliance, challenging due to high levels of dissolved salts which can cause physical and spectral interferences. Here, experts discuss monitoring and measuring anion concentrations in water from recycling impoundments, the typical constituents reported for Marcellus Shale fracking operations, flowback water preparation, and ICP-OES and ICP-MS metals analysis.
