Assess impact ability of waste-water of Vinh Loc industrial zone to running water quality

Abstract

At Vinh Loc industrial zone, people exploit well-water for domestic purpose. Pleistocene and upper Pliocene aquifers have been exploited primarily because of their qualities. The authors carried out a survey of surface water and ground water quality at the industrial zone to clarify the effect of waste- water to running water. Well-water samples were collected at both two aquifers and arranged toward underground flow. In addition, some of waste-water samples were also collected. The results showed that well-water quality is good, however, ammonia, iron, coliform, suspended solid were found in waste- water and exceeded the standard. The authors accessed influenced ability of waste-water to ground water by studying hydrological geology features of this area. Some of well-water samples had iron, ammonia content that exceeded the standard. It may be due to waste-water from the industrial zone. The surface water received the waste-water and geological features were the favorable conditions for polluted substances that can be flow to aquifers for time.
