Data on Environmental Earth Science Described by Researchers at Northwest University

  2012 AUG 24 (VerticalNews) -- By a News Reporter-Staff News Editor at Ecology, Environment & Conservation -- Investigators publish new report on Environmental Earth Science. According to news reporting originating in Lanzhou, People's Republic of China, by VerticalNews journalists, research stated, "The possible sources of water pollution and the evolution of water quality in the Malian River Basin of China's Longdong Loess Plateau were studied based on chemical analysis. Concentrations of major chemicals in the river were related to the distance downstream from the source of the river and the surface water in the upstream had good quality, while the river from Southern Huanxian County to Qingcheng County was seriously polluted."

  The news reporters obtained a quote from the research from Northwest University, "Groundwater quality was generally good in the phreatic aquifer beneath the loess plateau, with bicarbonate and calcium dominant, but salinity was high and petroleum pollution was present in many parts of the study area. Both surface water and groundwater quality have declined rapidly during the past 20 years, leading to much of the water unsafe to drink and unsuitable for use in irrigation. The substances released into the water included industrial wastes, domestic sewage, organic and inorganic fertilizers, and pesticides, as well as a range of other substances that are harmful to humans. However, petroleum contamination caused by the oil industry in the Longdong oilfield is the largest source of pollution that infiltrates surface water and groundwater, leading to deterioration of water quality."

  According to the news reporters, the researchers concluded: "It is recommended that oilfield management must be improved and the petroleum products and wastes must be disposed carefully to reduce the risk of further spills and pollution."
