Abstract: The technological advancements in a day-to-day life and increased industrialization have affected the quality of air and water available for use. The major impact of industries on the environment is the emission of gaseous, liquid and particulate materials into the newlineatmosphere which lead to air and water pollution. The polluted streams comprise of newlinecriteria pollutants and hazardous pollutants (as characterized by EPA). The criteria newlinepollutants include sulfur dioxide (SO2), nitrogen dioxide (NO2), carbon monoxide (CO), newlineozone (O3), suspended particulate matter (SPM), lead (Pb); while the hazardous air newlinepollutants include Volatile Organic Compounds (VOCs), ammonia (NH3), hydrogen newlinesulfide (H2S), etc. VOCs are the major pollutants released by the industries which newlinecontaminate the atmospheric air and the fresh water resources. VOCs are found to have newlineadverse effects on human health even at very low concentrations. Certain VOCs such as newlinetoluene, methyl ethyl ketone (MEK), methyl iso butyl ketone (MIBK), isoprene, newlinetrichloroethylene, benzene and chloroform are carcinogenic in nature and other VOCs newlinesuch as isopropyl alcohol (IPA), methyl acetate (MA), ethyl acetate (EA), butyl acetate (BA) also have serious health related affects on living beings. The petroleum hydrocarbons (benzene, toluene, etc.) are ground water pollutants which commonly result in leakage due to the or from storage tanks and spills. Thus, there is a need to control these emissions as they can cause serious damage to both humans and the environment. The present work deals with the biodegradation and biofiltration studies for the removal of VOCs from water and air. The potential of microorganisms in consuming the VOCs as carbon source makes biodegradation an attractive option for the removal of pollutants from the waste water streams. Biofiltration is one of the bio-based techniques to prevent the air and water pollution. This process is cost effective and is efficient for the removal of VOCs over other physical and chemical methods. This study is focused on the
