Overall performance tests: color, turbidity, odor and taste, visible to the naked eye, PH, total Hardness, aluminum, iron, manganese, copper, zinc, volatile phenols, sulfate, chloride, total dissolved solids, oxygen consumption, arsenic, cadmium, chromium (hexavalent), cyanide, fluoride, lead, mercury, nitrate nitrogen, selenium, carbon tetrachloride, trichloromethane, total bacterial count, total coliforms, fecal coliforms, residual chlorine and so on
Spiked test: arsenic, cadmium, chromium (hexavalent), fluoride, lead, nitrate nitrogen, Trichloromethane, carbon tetrachloride, etc.
