In this report ”The Environmental Quality Monitoring in Taoyuan County (2014)”, we choose several key parameters, the noise level, river water, dam water and ground water qualities, to monitor in Taoyuan County. We tried to obtain the trends in the monitored parameters and analyze the variations. The results contained an overview of indicative environmental quality and provided useful reference for future pollution control policies.
We measured environmental noise levels and traffic noise levels each in 12 different monitoring stations. The values were monitored consecutively for 48 hours twice per season. All noise levels were within safe limits according to the noise level regulation.
There are 32 regular monitoring wells and 3 military reserve wells in Taoyuan County. We got the water tested for ground water quality once per dry season and wet season. All analytical results were within safe limits according to type Ⅱ groundwater pollution standards, except the tetrachloroethene concentration too high in Gueishan industrial park and Pingzhen industrial park, the trichloroethylene concentration too high in Zhongli industrial park and the lead concentration too high in Yun An industrial park.
We set up 19 river monitoring stations to monitor the river water quality once per season. The analytical results showed slight or moderate pollution in most river water bodies. The criteria that exceeded the Class C terrestrial surface water quality standards were coliform bacteria, suspended solids, biological oxygen demand(BOD), ammonia nitrogen, dissolved oxygen, copper, manganese.
The water in Shihmen reservoir was sampled for dam water quality once per season. The analytical results met the Class B and C terrestrial surface water quality standards, except that the values of BOD, ammonia nitrogen and coliform bacteria were too high according to the Class A terrestrial surface water quality standards.
