§ 288.254. Sampling and analysis.
(a) A person or municipality operating a residual waste landfill shall conduct sampling and analysis from each monitoring point for the following parameters at the following frequencies:
(1) Quarterly, for ammonia-nitrogen, bicarbonate, calcium, chloride, fluoride, chemical oxygen demand, nitrate-nitrogen, pH, specific conductance, sulfate, total alkalinity, total organic carbon, total dissolved solids, turbidity, iron, manganese, magnesium, potassium and sodium.
(2) 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.
(3) Annually, for total and dissolved concentrations of each of the following: arsenic, barium, cadmium, chromium, copper, lead, mercury, selenium, silver and zinc.
(4) Annually, 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, ethylbenzene, benzene and xylene.
(5) Other constituents contained in the waste that may leach into the environment, as determined under § 287.132 (relating to chemical analysis of waste). For facilities with leachate collection and treatment, the quarterly analysis shall be adjusted to reflect parameters detected from leachate analysis under § 288.456 or § 288.556 (relating to leachate analysis and sludge handling; and leachate analysis and sludge handling).
(b) The Department may modify the requirements of this section, based on the waste analysis conducted under § 287.132 for residual waste monofills for parameters and monitoring frequencies that are not necessary to determine the actual or potential effect of the facility on surface or groundwater. This subsection does not apply to subsection (a)(1).
(c) For facilities permitted before July 4, 1992, the parameters described in this section shall be sampled and analyzed beginning October 5, 1992.
