Abstract: Physico-chemical properties of 25 water and 19 soil samples (includes one overburden) from coalmines in Wardha river valley located at Wani (Dist. Yavatmal, Maharashtra, India) were studied to assess the impact of mining activities on the surroundings. Out of 25 water samples, 7 samples contained slightly higher concentrations of measured contaminants and fall into the category of marginally safe sources for human consumption as per the standard BIS classification. However, some sources are found to be approaching the maximum permissible limits. Soil samples indicate adverse influence of mining activities on the soil quality. Overburden sample showed high acidic pH and exceptionally high TDS, chloride, nitrate, nitrite, sulphate, magnesium, iron, nickel, copper, manganese and zinc, which contribute extensively to the contamination of surface waters.
