Nitrogenous fertilizer industry generates high concentration of ammonia, urea, air emission (SOx, NOx, and COx SPM), ETP, sludge and spent catalysts wastes. These industrial hazardous waste of the NFL in Vijaipur are considered highly toxic in therefore disposal of such wastes needs proper attention so as to reduce possible environmental hazards. Industrial growth has resulted in generation of huge volume of hazardous wastes in the country. Hazardous waste management (HWM) is a very important issues and is assuming significance globally. Scientific disposal of hazardous wastes has become a major environmental issue in India. Hazardous waste (management & handling) rules, 1989 have been framed by Central Government and amended in 2000 and 2003 to deal with he hazardous waste related environmental problem that may rise in the near future. This paper gives details about the waste characteristics and management of NFL HW.

Water is most essential to life next to air only. Surface water and Sub-surface water both are very important for water supply for irrigation, industries and drinking purpose. Safe drinking water is primary needs of every person. Most of person mainly depends upon ground water sources. Some of these have problems such as excess hardness, Sodium, Potassium, Calcium, Nitrate etc. The natural quality of surface water and Sub-surface water tends to be degraded by human activities and geo environmental changes. Physico-chemical analysis of rivers and bore well and hand pumps has been collected in pre-monsoon (Aug-08) and Post-monsoon (Dec-08). Different parameter of water has been analyzed and assessed the suitability of drinking water in public hygiene scenario. Some parameters are with in the range as prescribed by ISI and WHO while other are beyond the limits.

A study was carried out on the impact of Chemical Fertilizer Industrial waste on the quality of soil in the vicinity. The Fertilizer Industry located at Jijaipur District Guna (M.P.) India, produce liquid ammonia and urea. All the solid waste generated are disposed off at dumpsites (Surrounding Fertilizer Plant). Teh effluent sludge and Soil sample were analysized for physio-chemical parameters viz pH values, Phosphrous, Sodium, Chromium, bulkdensity, porosity, water-holding capacity, electric conductivity, organic matter and Cation exchange capacity of soil using standard methods. The results revealed that the dumpsite sludge sample recorded very high concentration of Potassium and Calcium. The effluent samples from the outside showed lower value of Potassium and Calcium. The Soil environment around the dumpsite was the most affected the highest mean value of potash and phosphorous respectively.

The paper deals with analytical data of different type of parameters such as Ca2+, Na2+, K+, Turbidity and Temperature of pH, Hardness of surface H2O of sehore town. Eight different surface water samples were collected during August 2008. Results were discussed with respect to possible impact on Human Health.
