Analysis of Water Quality around Large Anthropogenic Emissions Sources in Eastern Thailand

By Arpa Wangkiat, Department of Civil and Environmental Engineering, Rangsit University, November 2006


The study evaluated variations in elemental compositions of water quality affected by large anthropogenic emission sources in Eastern Thailand: Map Ta Phut Industrial Estates which have housed over 90 industrial facilities including oil refineries, petrochemical and chemical facilities and hazardous waste landfills and treatment facilities.  For this purpose, eighty water samples were collected from water-well of twenty five surrounding communities in Map Ta Phut district, Rayong province during November, 2005 and February, 2006. The environmental parameters including temperature and pH were investigated during field measurement.  Twelve elements: Arsenic (As), Calcium (Ca), Cadmium (Cd), Cobalt (Co), Chromium (Cr), Copper (Cu), Iron (Fe) Magnesium(Mg), Manganese (Mn), Nickel (Ni), Lead (Pb) and Zinc (Zn) were analyzed by ICP-OES.  Results of an exploratory investigation of water wells indicated substantial contamination with all elements.  This reveled that a total sample were contaminated with heavy metal, by at least one metal was exceed Thailand’s standard of consume and drinking water in rural area.  The results of analyze provide valuable quantitative information regarding current levels of contamination, potential risk to public health, and will allow more accurate assessments of continuing monitoring and remediation efforts.
