ABSTRACT

Industrial wastes such as bunds, dusts, etc., make acid rain not only alter the quality of

fresh water, but also adversely affect the soil and ecological environment. Industrial

wastewater discharged into rivers affects the quality of river water and river basins. To

assess water quality use WQI (water quanlity index). After calculating WQI, it is based

on the classification of water quality, from which there is a suitable way of using water.

The process of calculating and using WQI in water quality assessment includes the

following steps:

Step 1: Collect and gather monitoring data from monitoring stations of continental

surface water (processed data);

Step 2: Calculate WQI values of parameters according to the formula;

Step 3: Calculate WQI;

Step 4: Compare WQI with the table of water quality assessment levels. Based on the

results of calculating the WQI the water is the more heavily contaminated and is in

need of treatment. Water at this location can only be used for navigation or irrigation

Facing this situation, Dong Nai province has carried out the project of relocating Bien

Hoa 1 Industrial Zone and transforming industrial zone into residential area and non￾agricultural land to prevent and overcoming the impact of Bien Hoa 1 Industrial Zone

on the Cai River basin environment and nearby residential areas.
