The study looked at how dyeing effluents from industries in Karur District affect the quality of groundwater. These effluents contain harmful pollutants like heavy metals and chemicals that can make water unfit for drinking and agriculture. The researchers found that untreated dyeing effluents are polluting the groundwater in Chellandipalayam, making it hard and high in total dissolved solids (TDS). They also discovered that using a reverse osmosis (RO) plant to treat the effluents can improve water quality. The study suggests using RO technology as a solution to clean up polluted groundwater in the area.
