A process and instrumentation diagram (P&ID), also known as a plumbing and instrumentation diagram, is a schematic of symbols that represents a complex system, such as a water treatment system. The symbols represent equipment such as filters, softeners, ultraviolet lights, storage tanks, valves, sensors and instruments. Typically, each piece of equipment and instrument on the P&ID carries a unique label.

Onset HOBO U24 data loggers are used to collect baseline specific conductance measurements to understand pre-gas conditions

Hydraulic fracturing holds promise for addressing both energy and employment challenges in the U.S. Experts estimate that the Marcellus Shale in New York and Pennsylvania alone could satisfy as much as 14 years of U.S. natural gas consumption and create nearly a quarter-million jobs.

However, hydraulic fracturing, commonly known as “fracking,” also brings risk of environmental contamination from salty flowback water containing potentially toxic and carcinogenic chemicals.
