treats wastewater collected from the District of Columbia sewer system and from the Maryland and Virginia suburbs. The treatment has two phases‚ in the first phase begins as debris and grit which is removed and trucked to a landfill where the sewage then flows into primary sedimentation tanks that separate the solids from liquids. The second phase is where oxygen is bubbled into treatment tanks so microbes can break down organic matter. Then the microbes convert ammonia into harmless nitrogen gas. Residual

Water pollution is the contamination of water bodies (e.g. lakes‚ rivers‚ oceans‚ aquifers and groundwater). Water pollution occurs when pollutantsare directly or indirectly discharged into water bodies without adequate treatment to remove harmful compounds.
