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. Water pollution affects plants and organisms living in these bodies of water. In almost all cases the effect is damaging not only to individual speciesand populations‚ but also to the natural biological communities. Introduction[edit]

Comprising over seventy percent of the Earth’s surface‚ water is undeniably the most valuable natural resource. Life on Earth would be non-existent without water because it is essential for everything on our planet to grow. The human body is composed of 50-80% water. Blood and muscles contain significant amounts‚ and approximately 95% of the brain is water. All body systems and organs need water to function properly‚ and will shut down without it. Most of the chemical reactions that take place in

Effluent levels‚ after treatment‚ can vary greatly so careful consideration needs to be given to its disposal for the fear that it may seep into our ground water or municipal water supplies. Fluoridation in the municipal water supplies is a controversial topic‚ specifically in

Due to lack of suitable alternative‚ waste water is discharged without any form of treatment into the ocean thereby polluting the water and harming the ecosystem.

sewers. Such systems are usually avoided since they complicate and thereby reduce the efficiency of sewage treatment plants owing to their seasonality. The variability in flow also leads to often larger than necessary‚ and subsequently more expensive‚ treatment facilities. In addition‚ heavy storms that contribute more flows than the treatment plant can handle may overwhelm the sewage treatment system‚ causing a spill or overflow. Modern sewer developments tend to be provided with separate storm drain

parasitic disease known as Giardiasis. Although it is a global disease‚ it is most common in developing countries where “nearly 33% of people [in these regions] have had [Giardiasis]” (Parasites - Giardia). These countries possess inadequate sewage treatment‚ water scarcity‚ and overpopulation‚ which all contribute to the expansion of Giardiasis. A majority of pathogenic microbes are linked to several species such as parasitic worms‚
