Abstract

Eutrophication is a major water environmental problem in many countries. This study intends to introduce a basic methodology to assess water quality in natural water sources. Lake Sanaru in Japan and Lake Dianchi in China were used as case studies. We studied the pollution mechanisms in these two lakes by analyzing data from aqueous environmental samples and other related factors. Then, a simple and practical simulation model was proposed to express material balances around the two lakes of several constituents present in water. Material balance equations were used to calculate the internal productions of several constituents. Finally, purification methods and pollution loading for water quality targets were discussed.
