Inorganic Water Tests

Fast Turnaround, Accurate Results

Test	Description
Chloride	Major anion in water (salty taste). High concentration may harm metallic pipes, structures, and growing plants.
Chlorine	Used to destroy disease-producing microorganisms. Improves water quality with regards to ammonia, iron, manganese, sulfide, and organic substances. Too high of concentrations affect taste and odor.
Fluoride	Both naturally occurring and added at controlled amounts. WI State Standard for Drinking Water: 4 mg/L.
Nitrate	Excessive amounts in drinking water can lead to methemoglobinemia in infants. WI State Standard for Drinking Water: 10 µg/L prevents methemoglobinemia from occurring.
Nitrite	Intermediate oxidation state of nitrogen and reduces to nitrate. WI State Standard for Drinking Water: 1 mg/L.
Sulfate	Widely distributed in nature. In the presence of organic material, certain bacteria will become active.
Total Phosphorus	Essential in organism growth.
Silica	Coarsely crystalline (quartz, rock crystal, amethyst) and micro-crystalline (flint, chert, jasper) can form scale deposits in boilers.
