Evaluation of groundwater environmental quality in a power plant construction site in Guangdong Province
Based on analysis of the hydro-geological conditions in the study area,groundwater environmental quality in the construction site of Guangdong power plant was evaluated using single-factor index method.Results showed that the over-all quality of groundwater environment was good,but there were some indexes such as nitrite,COD and mineral oil exceeding standard in local areas.The nitrite in groundwater that exceeded the quality standard mainly occurred in low-lying areas in some valleys,and these low-lying areas are mostly groundwater discharge areas and agricultural production regions.The ni-trite in groundwater in these low-lying areas was gradually enriched,with the combined effects of hydrogeological conditions and non-point source pollution from agriculture.This study can provide scientific basis for groundwater environmental impact assessment and water resources scientific management.
