Standard – Basic tests for which drinking water samples should be routinely tested. Tests included – total coliform bacteria, E. coli bacteria, pH, and total dissolved solids.

Aesthetics/Corrosivity – Includes tests from standard package plus those for water components that can contribute to bad taste, staining, scaling and corrosivity. Tests included – total coliform bacteria, E. coli bacteria, pH, total dissolved solids plus hardness, corrosivity index, copper, iron, and manganese.

Aesthetics/Corrosivity Plus Lead – Includes all tests from aesthetics/corrosivity package (above) plus first draw and running water tests for lead. Tests included – total coliform bacteria, E. coli bacteria, pH, total dissolved solids plus hardness, corrosivity index, copper, iron, and manganese and first draw and running water lead.

Agriculture/Septic – Includes tests from standard package plus nitrate-nitrogen, which may be elevated in water supplies located near intensively managed agricultural sites or in proximity to densely spaced or poorly operating septic systems. Tests included – total coliform bacteria, E. coli bacteria, pH, total dissolved solids plus nitrate-nitrogen.

Mining – Includes tests from standard package plus those of greatest importance for water supplies located near existing or future mining activity. Tests included – total coliform bacteria, E. coli bacteria, pH, total dissolved solids plus aluminum, iron, manganese and sulfate.

Gas/Oil – Includes tests from standard package plus those of greatest importance for water supplies located near existing or future gas and oil well-drilling activity. Tests included – total coliform bacteria, E. coli bacteria, pH, total dissolved solids plus barium and chloride.

Trace – Includes tests from standard package plus trace elements and metals that may be present in water supplies located near industrial waste or dump sites. Tests included – total coliform bacteria, E. coli bacteria, pH, total dissolved solids plus arsenic, barium, cadmium, chromium, copper, lead, nickel, mercury, and zinc.
