Is CBNG produced water “salty”?
Some folks consistently refer to the water produced from coalbed natural gas production as “salty”. This is not an accurate characterization. In fact, the water produced from coalbed natural gas production is closer to the technical definition of freshwater than it is to saline water. Fresh water, as defined by the United States Geological Survey (USGS), is water that contains less than 1,000 milligrams per liter (mg/L) of Total Dissolved Solids (TDS). The water produced at Fidelity’s project near Decker, Montana, contains fewer than 1,500 mg/L of Total Dissolved Solids (TDS).
