THE RESULT OF THE NON-COMPLIANCE ASPECTS FOR THE AIR AND WATER, IN THE OIL EXTRACTION OF SUPLACU DE BARCĂU AND THE MEASURES REQUIRED FOR THEIR PROTECTION
Journal Title: Natural Resources and Sustainable Development - Year 2019, Vol 9, Issue 1
Abstract
Pollution of air, water and soil in the Barcău basin is due to anthropogenic activities carried out in production units that aim to exploit oil and gas fields and crude oil processing. Following studies on gas emissions to the atmosphere, as a result of the oil extraction activity on the S.C. PETROM S.A. Suplacu de Barcău, nonconformities were found in accordance with the Environmental Legislation, due to high concentrations of carbon monoxide – CO. The value of 7.5 mg/m3 in the oil extraction fields exceeds the maximum admissible concentration of 6 mg/m3. The main cause of pollution of surface water is the discharge of industrial waste waters. The physico-chemical characteristics of the industrial waste waters indicates exceedances of the permissible legal limits, observed at the entrance to the treatment plant for both years of observations (2010 and 2011) at: CBO5 1177 - 1484 mg/l; Phenols 3.2-3.4 mg/l; The filtration residue 1968 – 1988 mg/l; The dry residue (MTS 105 ˚C) 611- 914 mg/l; The fixed residue (MTS 600 ˚C) 101 – 116 mg/l; The volatile residue (MTS volatile) 81 – 89 mg/l. Due to the dilution recorded after the wastewater discharges treated in the Barcau River, the values of the main monitored physicochemical indicators fall within the permissible limits, being below the maximum values of STAS 4706-88, Category III rivers, except the oil products indicator, which is more than 5 times the admissible value. The main technical and organizational measures necessary to prevent the pollution of the Barcău River are: the increasing the efficiency of the treatment plant, identifying the sources of accidental pollution, stopping discharges and removing them.
