Huge amount of fly ash is being generated from combustion of coal in 145 existing thermal power plants, which contributes to 70% of the total energy requirement of the country. Present production of fly ash is 184 million tons per annum, which is projected to exceed 440 million tons per annum by 2030. This gargantuan quantity of fly ash not only poses environmental problems but occupies large areas of land for its disposal, which needs urgent and appropriate measures for its safe disposal and gainful utilization on sustainable basis. The study carried out by Central Institute of Mining and Fuel Research, Dhanbad on the bulk utilization of fly ash in agriculture and forestry sectors under different agro-climatic conditions and soil types for last two decades, indicates that pond ash is superior to soil in respect of plant nutrients and other physico- chemical properties. Keeping this in view, field scale study has been carried out in pond ash amended wasteland of farmer at Bhusawal (Maharashtra) followed by its irrigation with percolating water of ash pond for cultivation of cotton crops. The enhanced yield and quality of crop, improved soil condition and its residual effect on successive crops for longer period shows its potential for reclamation of waste/degraded land.

Keeping view fly ash as a useful ameliorant that may improve the physical, chemical and biological properties of problematic soils and as a source of plant nutrients (macro and micro), field demonstration trials were carried out on 8.4 acre of unutilized and undulating low lying area at Kali Mela, Jamadoba, Dhanbad filled with Tata Steel's FBC ash (up to a depth of 4 m) to reclaim it using biological amendments such as top soil layer (4 cm), cow dung manure, coco peat, vermi-compost, bio-fertilizer and NPK fertilizers (suitable proportions), selection and plantation of adaptable plant species (forestry, fruit bearing and oil yielding) . The planted species were monitored in respect of growth and biometric parameters at different growth stages followed by physicochemical and biological characterization of ash filled low land. The obtained results evinced that among the physicochemical properties, textural composition, bulk density, water holding capacity, porosity, and major/secondary and micro-nutrient levels of ash filled low land significantly improved with the progressive growth of planted species apart from considerable improvement in growth/biometric parameters and physiological behavior of the planted species. The different biological parameters (ectomycorrhiza, N-fixing bacteria, P-solubilizing bacteria, and dehydrogenase activity) were found to have increased at successive stages of the plantation. The beneficial uses of fly ash in agro-forestry applications were popularized periodically among the local farmers/inhabitants. As such the low lying area could be sustainably reclaimed using fly ash in bulk scale through biological means, which can be further extended in the vicinity of other power plants in the country.

Scientifically, real world problems are complex and are not well defined. The main reasons of these problems are the uncertainties, interdependencies and situations of elements under consideration. Fuzzy logic may be appropriate to solve such complex problems and it provides an acceptable solution in an ambiguous environment. In other words, using fuzzy logic, a real and clear solution of a problem can be drawn from an ambiguous situation. This principle is called fuzzy logic. Fuzzy logic methodology executes in three steps, fuzzification, inference and defuzzification. It represents a problem in natural and linguistic terms rather than representing the problem by the relationships between crisp values. Fuzzy logic is often used in decision making systems as it can solve complex problems in an easy way. Fuzzy logic plays an important role in solving and analyzing natural and environmental problems. In this research paper the fuzzy logic, supervised and unsupervised fuzzy logic methods, used for drinking groundwater quality and availability assessment, have been reviewed in detail. Supervised fuzzy logic requires a prior knowledge about physical, chemical and biological information of drinking groundwater. Supervised fuzzy logic is a hybrid methodology, which may integrates capability and functionality of Artificial Neural Network. In this methodology working of system can be controlled by user and the result of system depends on internal functioning of Artificial Neural Network. This research paper ensures that how and why fuzzy logic is superior to traditional methods of drinking groundwater quality assessment.
