Microorganisms
Green Water Technologies says that microorganisms is a blanket term for all types of parasites, bacteria, and viruses. Although the entire earth is covered in microorganisms, some, often those deriving from animal waste or human sewage, can cause extreme gastrointestinal disturbances.
Nitrate
Nitrate is a chemical found in animal waste, fertilizers, and sewage. It can enter a private well from miles away through underground water movement. An oversaturation of nitrates can cause a condition known as “blue baby syndrome.” Green Water Technologies says that, while rare, this can be fatal to infants younger than six months.
Heavy metals
Heavy metals, while sometimes deriving from natural mineral deposits, are most often the result of nearby mining or petroleum operations, public waste disposal, and plumbing and service lines. Green Water Technologies explains that taking in heavy metals in high levels can cause anemia, intestinal damage, acute toxicity, and even cancer.
Fluoride
Green Water Technologies notes that most municipal water sources add fluoride to help prevent tooth decay. But, in excess, it can actually cause pitting of the teeth, dental fluorosis, and even skeletal fluorosis, which can result in tender joints and bones.
