Copper can cause liver and kidney damage. Its found in mine wastes, and erosion of natural deposits. Giardia lamblia can cause diarrhea, cramps and puking. Its found in human and animal wastes. Lead can cause delays in physical and mental development in babies and children. Its found in the rotted pipes and the erosion of natural deposits. Arsenic can cause s kin damage, problems with the circulatory system and it may increase your risk of getting cancer. Its found in the erosion of natural deposits, runoff from orchards and glass and electronics production wastes. Toluene can cause problems in the nervous system and cause kidney or liver problems. Its found in the waste from petroleum factories.

The process of how water is first flocculation. This step gets rids of dirt and other particles in the water. Aluminum and iron salts or synthetic organic polymers is added to the water, which forms tiny sticky particles called "floc" which attract the dirt particles. The next step is called sedimentation where the flocculated particles settle naturally out of the water. The step after this is called filtration where many water treatment facilities use filtration to remove all particles from the water. Those particles include clay, silt, natural organic matter, precipitates from other treatment processes in the facility, iron, and microorganisms. Filtration clarifies the water and enhances the effectiveness of disinfection. The fourth step is called disinfection. Disinfection of drinking water is considered to be one of the major health advances of the 20th century. Water is usually disinfected before it enters the water system to make sure that dangerous microbial contaminants are killed. Chlorine, chlorinates, or chlorine dioxides are the most often used because they are very effective, and small concentrations can be used in the water system.

You can tell weather you water safe to drink is to test your water once in a while to make sure there's no virus in it. Also if your water is cloudy or smells bad that's a major clue your water is probably unhealthy. Some tests you can do are Activated Carbon Filter (includes mixed media that remove heavy metals) Adsorbs organic contaminants that cause taste and odor problems.

Ion Exchange Unit Removes minerals, particularly calcium and magnesium that make water “hard” Some designs remove radium and barium Removes fluoride

Reverse Osmosis Unit Removes nitrates, sodium, other dissolved inorganics and organic compounds Removes foul tastes, smells or colors

Distillation Unit Removes nitrates, bacteria, sodium, hardness, dissolved solids, most organic compounds, heavy metals, and radionucleides Kills bacteria Does not remove some volatile organic contaminants, certain pesti- cides and volatile solvents Bacteria may recolonize on the cool- ing coils during inactive periods

Through a process called forward osmosis, a novel solution the company developed pulls water molecules across a membrane, leaving salt and impurities behind. When low temperature heat is applied, the bioengineered solution separates out like oil, allowing clean water to be siphoned off. This method of cleaning uses less than a quarter of the electricity needed for standard desalination.
