Abstract

The rapid industrialization in eastern China has made great contributions to the growth of the country’s economy while also degrading the environmental quality. Yet the government is reluctant to release the environmental information to the public, resulting in a barrier for concerned citizens to participate. This study focuses on the water quality of Yue-Guan Canal in Yueqing, Zhejiang, where private rural enterprises have mushroomed since the 1980s. The objective of this study is to 1) test the water quality of the canal based on pH, total dissolved solids (TDS), copper (Cu), ammonia nitrogen (NH3-N) and hexavalent chromium (Cr VI); 2) determine the relation between water quality and land use and land cover (LULC), and model the water quality of the whole canal based on LULC; and 3) make the information available to the public via an online geographic information system (GIS) platform. I chose six sampling sites along this 27 km canal, and collected samples on 3 workdays and 3 non-workdays in December 2012 and January 2013. I found an excess of NH3-N made the water samples of all sites fail to meet the national standards for Class V water. I created regression models for pH, TDS and Cu in relation to LULC, but all resulted in low R2 values, which may suggest point sources contribute more pollutants than non-point sources. I published the map and the data as a web application for the public.
