The influence of oil development on water quality of Agan River in West Siberia

摘要

Stream water chemistry based on long-term monitoring data from 2008 to 2011 were analyzed across Agan River (West Siberia, Russia). Spatial distribution of constituents indicated pollution mainly from non-point sources associated with oil development. Data revealed that the major spatial variations of the hydrochemistry are related to the salinity and oil pollution. Chloride and total petroleum hydrocarbons (TPH) exhibited wide concentration range according environmental impact level. The salinity of the river water increases substantially as it crosses areas affected by intensive oil development. For 5 percent of sampling events, TPH concentrations were above the recommended water quality standards. Assessment of the water quality can enhance understanding environmental hazard and effective management of water and biological resources.
