Objective To analyze the basic situation of water quality of Heilongtan reservoir in Renshou County in recent 10 years and provide a scientific basis for ensuring drinking water hygiene safety of nearly 2 million people in Renshou County and Dongpo District. Methods According to the flowing direction of reservoir water body, it is divided into four sections, each section is divided into upper, middle and lower three layers, and each water sample is collected during dry season and wet season. Results In addition to the cross-section of the water chroma, the other sections of the seized items have reached the second-level water source water standards; 2003-2006, the highest passing rate of water samples, 2007-2012 water sample pass rate difference was not statistically Learning significance; four cross-section, the inlet section of the lowest pass rate.
