ABSTRACT: Groundwater samples from 62 locations have been collected from Tirupur region viz. Avinashi, Tirupur and Palladam taluks of
Coimbatore District. The extensive agricultural industrial activities and urbanization resulted in the contamination of the
aquifer. To study the contamination of groundwater, water samples were collected in an area of 180km2 and analysed for major cations and anions. Most of the locations are contaminated by higher concentration of EC, TDS, K and
NO3. Major hydro chemical facies were identified using Piper trilinear diagram. Based on US salinity diagram, most of the samples
fall in the field of C3S1, indicating high salinity and low sodium water, which can be used for almost all types of soil with
little danger of exchangeable sodium. Majority of the samples are not suitable for domestic purposes and far from drinking
water standards. However, PI values indicates that groundwater is suitable for irrigation.
