Hr. Dan~el A. Page F ire to a fixed object which permits direct readings of water levels. A witness post, as used at SW-2, 3, and 5, is a metal post with a reference point from which water level measurements are made with a tape measure from the reference point to the water level. Both types of surface water measurement gauges have a reference point which has been surveyed to a common datum (National Geodetic Vertical Datum). Water Quality -- Ground and Surface Water 11. pages 14 and 15. As described in Item 5 above, it was our understanding that a review'of preliminary initial data was not required in the Evaluation Report. The analytical data to which you refer (April 1985 inorganic parameters) are being compiled and evaluated. Preliminary interpretations from this data and subsequent water quality data will be discussed when the package of preliminary interpretative information is shared with the MPCA in October. Waste Characterization 12. ~ages 16-20. An understanding of the wastes disposed at the Anoka Sanitary Landfill is being expanded as more information is gathered. It is understood that significant findings of the waste characterization search may have an impact on the on-going water quality monitoring program. Significant determinations of this search will be shared with the MPCA as they become available. 12A. Anoka County records are available (Attachment 2) which imply that hazardous waste was deposited at the Anoka Sanitary Landfill. To the best recollection of the Site ~nager, Don Otter, the County records are inaccurate because of recording irregularities by WMMI gate personnel, which was the source of the County data. It is believed that sewage sludge from the City of Anoka was inadvertantly categorized as hazardous waste because there was no other place on the reporting form for this type of material. The recollection of the Site Manager indicates that the volume of reported hazardous material on the form and the volume of sewage sludge are strikingly similar. Based on this recollection, the reported hazardous material is believed to have been non-hazardous sewage sludge. The data was provided to Anoka County monthly as a provision of the Anoka County permit requirement. 12B. In lg81, WMMI Corporate Environmental Counsel requested that information about previous landfill activities concerning potential hazardous waste disposal be documented. The information was provided by Don Otter, the Site Manager, during the early operation of the landfill by WMMI. The instruction from Corporate management was to report all potential hazardous waste disposal. The instruction was "when in doubt, report it." The Site Manager submitted information about potential hazardous waste disposal to Corporate Environmental Counsel, who then filed the information as required by RCRA. Telephone calls and a documents search are being conducted to gather additional information.
