FA (FA) is a major output of Thermal Power Plants (TPP) formed when coal is burnt it produces Fly Ash (FA) trapped in Electrostatic Precipitator termed as EPA and left over at bottom of power plants. As per Government of India, this Fly ash can be directly used as better option for landfill material during any construction of Overbridges and Underpass in and around Maharashtra State. During our study, we do find apart of its major use as Land filler option it create havoc in environment. Study comprises two distinct methods Direct Observation and Line Transect Methods. To accomplish objective overall six villages were selected in and around site of construction. Our result suggest chemical contents of FA are extremely hazardous for local villagers it contains mercury,antimony , silica, aluminum oxide , ferric oxide and other oxides material acting as passive contributing factor in physical environment causing all three major types of pollution viz. air pollution ,water pollution , and soil pollution resultant consequences of human health problems .residing nearby construction highway areas .For sustainable power production there are recommended package and practices as measure to be adapted by Government of India .
