Natural gas is quickly developing globally as an alternative to petroleum-based energy sources. The process of extracting gas from shale rock formations—called hydraulic fracturing or fracking—is also developing rapidly. Current extraction methods require large quantities of water from natural sources, and the various steps of the process may pose threats to human and environmental health if not controlled and monitored effectively.
YSI instruments, such as the EXO multiparameter water quality sonde, or ProDSS, can be deployed to easily and efficiently collect data on any combination of parameters, either down-well, in a flow cell, or in surface water including nearby streams, rivers, or lakes. Sensors can be installed down-well to take spot sample measurements or used continuously for long-term unattended monitoring with options for telemetry enabled data transmission.
