The use greywater (GW) for irrigation and other non-potable uses has been proposed as a method to conserve water resources. These uses would result in the direct discharge of this water to the environment with minimal treatment. The presence of antibacterial compounds in greywater raises concerns regarding potential impacts of these materials on the environment and human health. Our research examined the possible modification of microbial communities within the soil due to the presence of a commonly used antibacterial agent, triclosan. Along with community structure, we also looked at any selection for antibiotic resistance in bacteria associated with constant exposure to triclosan.
