Bottled water is tested for two types of contaminants: aesthetic and health-related.
Aesthetic contaminants affect the taste, odor, or color of the water. Aesthetic contaminants include:
o Inorganic parameters such as iron or sulfate, and
o Physical characteristics such as pH.
Health-related contaminants may affect the health of consumers. Health-related contaminants include:
o Inorganic parameters such as arsenic or nitrate;
o Volatile organic chemicals like benzene;
o Chlorination byproducts;
o Radionuclides, and
o Coliform bacteria.
