Due to the surface mining at Makrana, the flora, hydrological relations and soil biological systems are drastically disturbed. In Makrana the main cause of environmental pollution is marble mining dust particulates and stone crusher dust. Analysis of the samples showed that the soil of Makrana is saline sodic because of high pH value and excess sodium presence. The agricultural field near these marble mines and stone crushers areas show poor growth and yield of crops and vegetable crops was noticed.

The quality of ground water across the Bareilly city has been determined by analyzing different physico-chemical parameters. Alkalinity and hardness of groundwater is beyond the WHO limits. Water quality index of different sites is also calculated.

Industries without a concern for the environment deteriorate the land, water and air in an area. When the industrial activity is located in the coastal zone the harm it causes to the varied components of the environment becomes irreparable.

Effluent samples were collected from a tannery in Ambur, near North Arcot Dist, Tamil Nadu, India. The physico-chemical parameters of the effluent viz, colour, odour, pH, Electrical conductivity, TSS, TDS, BOD, COD, total hardness, calcium hardness, magnesium hardness, chloride, sulphate and total chromium were determined. The results revealed that almost all the parameters of Tannery Effluent were found to be high and exceeding the CPCB limits.

One of the industries that cause pollution of considerable magnitude in Tiruchirapalli district is tannery. Sembattu, the study area known for its location of the airport in the district is a fast developing urban site. Number of tanneries located in the area whose effluents often left untreated affect the land and water of the surrounding regions. 

The importance of environment in our daily life is well known. It adversely affects not only human lives but also to the coming generation. The present paper mainly deals with the methodology of cost benefit analysis which is dependent on the types of project.

The wastewater generated from textile industries of Bhilwara city is studied for its characterization. Wastewater of textile industry was found to contain a high degree of pollutants with high TDS and suspended solids. The wastewater is highly colored and viscous due to dyestuff and suspended solids respectively.

The present paper deals with the drinking water quality analysis of some bore-wells of Ward No. 17 of Chikhli town. The various parameters studied are colour, taste, odour, pH, turbidity, total dissolved solids, total suspended solids, total hardness, calcium hardness, magnesium hardness, copper, iron, chlorides, sulphates, nitrates and fluorides.
