(1) Quarterly, for ammonia-nitrogen, bicarbonate, calcium, chloride, fluoride, chemical oxygen demand, nitrate-nitrogen, pH, specific conductance, sulfate, total alkalinity, total organic carbon, total phenolics, total dissolved solids, iron, magnesium, manganese, potassium and sodium.

(2) Quarterly, for the following volatile organic compounds: tetrachloroethene, trichloroethene, 1,1,1-trichloroethane, 1,2-dibromoethane, 1,1-dichloroethene, 1,2-dichloroethene (cis and trans isomers), vinyl chloride, 1,1-dichloroethane, 1,2-dichloroethane, methylene chloride, toluene, ethyl benzene, benzene and xylene.

(3) Quarterly, for groundwater elevations in monitoring wells recorded as a distance from the elevation at the well head referenced to mean sea level based on United States Geological Survey datum.

(4) Annually, for total and dissolved concentrations of the following: arsenic, barium, cadmium, chromium, copper, lead, mercury, selenium, silver and zinc.

(5) Annually, for the following volatile organic compounds: 1,1,1,2-tetrachloroethane, 1,1,2,2-tetrachloroethane, 1,1,2-trichloroethane, 1,2,3-trichloropropane, 1,2-dichlorobenzene, 1,3-dichlorobenzene, 1,4-dichlorobenzene, 2-dichloropropane, 3-chloro-1-propene, 4-methyl-2-pentanone, bromomethane, carbon tetrachloride, chlorobenzene, chlorodibromomethane, chloroethane, chloromethane, cis-1,3-dichloropropene, trans-1,3-dichloropropene, dichlorodifluoromethane, methyl ethyl ketone, tribromomethane and trichlorofluoromethane.

(6) Annually, for ten volatile organic compounds not otherwise identified in this section, based on those compounds showing the greatest apparent concentration from the peaks of a mass spectra of each sample. These ten compounds shall be identified but their concentration does not require measurement.
