E. coli

in water is a sign of fecal contamination, meaning the water may contain harmful microorganisms from animal or human waste

Sodium Hypochlorite

a chemical compound known as household bleach, used as a disinfectant, sanitizing agent, and stain remover for various applications, including cleaning toilets, removing mold, and treating swimming pools

Chlorine 

Chlorine disinfects tap water by killing bacteria and viruses, making it safe to drink. However, it can cause an unpleasant taste and smell. Standard chlorine levels are considered safe, with minimal impact on home filtration systems.

Fluoride

Long-term excessive fluoride intake, especially from groundwater, can cause dental fluorosis, weakening and discoloring teeth. It may also lead to skeletal fluorosis, making bones brittle and joints stiff. Very high exposure can affect the thyroid or cause nausea and vomiting in severe cases.
