Groundwater in Selangor has been widely used for industrial and agriculture sectors as well as for drinking water suppliers and domestic uses in certain areas. The extensive use of groundwater was to accommodate the high demand for fresh water. Despite acting as the main substitution for fresh water, they are unexceptionable to be exploited. Extracting groundwater from a dug well usually comes with the negative impact of uncontrolled basis, untreated and unmonitored. Such behaviors further threatened the availability of fresh groundwater. Looking at the data available from 2015 – 2019, Department of Environment (DOE) have monitored the groundwater status based on it physico-chemical parameters around Petaling and Sepang districts.  Data on the groundwater index display most stations are preferable to treat prior to consumption. Development throughout the years makes a significant change when several wells have transited from good status to unsuitable for drinking. Some of the pollutants in the groundwater was either accumulated or diluted. NO₃ and Pb for example accumulated from 2015 to 2019 as the land use particularly were practice industrial and agricultural activities. Anthropogenic activities such as municipal effluents discharged, agricultural runoff containing a considerable amount of chemical fertilizer, and atmospheric deposition are all responsible for these contamination in the groundwater. Meanwhile, Cr and Zn concentration have improved due to dilution process.
