ABSTRACT

West Lake is currently facing serious water pollution due to a rapid urbanization and

population growth, but the levels of pollution are not the same at different points across the

lake. This research aims to asses the quality of surface water of West Lake, identify causes of

the issues and to propose appropriate solutions to protect and recover West Lake‟s water

quality. The research was conducted by applying the following principal methods: literature

review, field surveys, sampling and laboratory analysis and desk analysis. The findings

demonstrate that the water quality is relatively good at the middle of the lake (Point P2, Table

5.6) whereas the water quality is worsen when getting near the lakeside since it is

contaminated by the sewage from the city (Point S2, Table 5.6). It is proved by the data of

Table 5.6 that the quality of water at point P2 satisfied almost least requirements (except

Phostphate) while the quality of water at point S2 did not qualified several requirements

(Those are BOD5, COD, Phostphat, Ammoniac, Coliform). To protect the lake, this research

proposes to build new wastewater treatment plants and new drainage systems around the lake,

and then inhibit any business activities that are currently running on the lake. These solutions

are expected to be applied not only to West Lake but also applicable to other water bodies

within mega cities in Vietnam.
