Rain water samples were collected from five locations from Jindal Chowk, Red Square Market, Grain Market, Milgate and Gangwa of Hisar for physico-chemical properties of rain water, during the months of June, July and August 2013. The first four locations were industrial and market layouts while the last one was a rural, non-industrialized community on the outskirt of Hisar. The result of the rainwater samples indicated the average values of colour (6.6, 6.0, 6.2, 6.0 and 5.0 Hazen units); turbidity (0.18, 0.162, 0.161, 0.163 and 0.16 NTU); chloride (14,12.6, 13.3, 12.6 and 10.6 mg/l); total hardness (23.0, 21.3, 22.0, 15.1 and 14.3 mg/l) at Jindal Chowk, Red Square Market, Grain Market, Milgate and Gangwa respectively. The pH values of the rain water from the four industrial locations indicated slightly acidic i.e. pH<6.6 in the month of June 2013. In this study a correlation was established between the industrial sites and rainwater that water became acidic due the gases emitted by industries.
