Monitored Natural Attenuation (MNA)
Scientific research does not stand still. New types of bacteria are being discovered every year, such as those involved in the degradation of benzalkonium chlorides (BAC, a cleaning and disinfecting agent) and in 2017 a species that anaerobically degrades benzene. Many contaminants can be degraded by bacteria, also in soil …
