Abstract
Water is one of the most indispensable resources and is the exilier of life. Water pollution is a very serious problem in our country. The water quality index (WQI) and heavy metal pollution index (HPI) is an important parameter for determining the groundwater quality for the users. The study for the same has been carried on the ground water by collecting ground water samples from industrial area Kashipur, India. In order to develop WQI the samples were analyse to physico-chemical parameters i.e., pH, conductivity, total alkalinity, total hardness, calcium, magnesium, chloride, nitrate, sulfate, total dissolved solids, dissolve oxygen, BOD. To calculate the HPI, some heavy metals like arsenic, chromium, cadmium, lead, copper and zinc were determined using AAS. Geographical information system and global positioning system (GPS) had been used to map the studied area. The WQI index for the study area had been calculated and the values ranged between 71.50 to 170. Only one sample comes under the poor water quality category (50-70) and the three sample of ground water comes under the category of very poor quality (75-100). Whereas, the six samples of potable water were unsuitable for the drinking purpose (>100). As per the calculation the heavy metals pollution index for the various samples range between the 59.7 to 119.6. Only one sample comes under the poor water quality category (5070) with the WQI 59.7 and the five sample of ground water comes under the category of very poor quality (75-100). Whereas, the four samples of ground water were unsuitable for the drinking purpose (>100). The high computed value shows that the ground water is contaminated with industrial effluent. The study area is surrounded by pulp and paper mill. The result reveal that samples are not suitable for the drinking purpose and need proper treatment before consumption and needs proper measures for further contamination.
