Study finds high sodium bicarbonate concentrations in water from coal-bed natural gas production harms aquatic life; water treatment can mitigate effects

Green Car Congress

Produced water from coal-bed natural gas (CBNG) production may contain sodium bicarbonate (NaHCO 3 ) at concentrations that can harm aquatic life, according to a new study by the US Geological Survey; Montana Fish, Wildlife and Parks; the Bureau of Land Management and the US Environmental Protection Agency. Salts such as sodium bicarbonate are found naturally in the water along the coal-bed natural gas seams.
