Abstract

In the present study the impact of pesticide pollution due to the discharge of pesticide waste water from the agricultural field in the Sirumalai agro lands was studied. In order to evaluate the physical and chemical parameters of water, the pond water samples, and the ground water samplesall the sides were collected and analyzed for various water quality parameters and soil parameters. The pond water is the main source of water for the bore wells located in and around the agricultural land. During the rainy season the pond water percolates into wells and bore wells. Now water is completely polluted due to percolation of pesticide waste waters which are potentially harmful, accumulation of various pesticides chemical residues in water reaches the ground water source. Bio – accumulation and bio-concentration of the pesticide waste water causes high degree of pollution. The bore wells in and around the northern side of the pond polluted with very high TDS and it is beyond redemption due to the higher limits of TDS, hardness, phosphate, ammonia and nitrate. All the water samples taken in and around the agriland are notchemically portable. The presence study reveals that the physico-chemical analysis of pond water in the pond as well as ground waters are above the permissible limit. The dissolved oxygen is analyzed and found to be deteriorated. It is due to utilization of dissolved oxygen in the water byorganic matter and by the pesticides. The investigator observed that the solar evaporation tank made of black body tank, function more effectively during summer with very high evaporationrate. The investigator found that during the normal operation period, the colour of the effluent varies and becomes clear after treatment with alum, which favours the penetration of solar energy easily and hence the efficiency of the evaporation tank increases than the normal cement slab. The advantage of utilizing the black body natural kadappa tanks for evaporation is very strong and it can absorb very high degree of solar radiation which is converted into thermal energy. The investigator observed that the solar evaporation tank made of black body tank function more effectively during summer with very high evaporation rate. The solar evaporation tank is blessed in principle of black body surface which can absorb solar radiation more effectively than ordinary cement slab.
