It was recommended following that assessment, that some remediation of soil be undertaken, to raise pH and lower sulphate levels. This was undertaken by Mr Sherriff and Dames & Moore were commissioned to execute a secondary phase of investigation and validation sampling to assess the state of the site following completion of the remedial programme. The works to date have been undertaken as part of the regulatov process for the proposed rezoning of the site from a Rural 1 Zone to a Landscape Living 2 Zone by the Shire of Upper Yarra. The purpose of the study was to provide Mr Sherriff with information regarding the environmental quality of the site to satisfy the Upper Yarra Shire council with regard to their requirements for rezoning of the properties for residential development. The scope of work for the investigation, remediation and validation of the site included the foll- e A review of the information provided by Mr Sherriff and information collected from the public record; e An inspection of the site to determine potential sources of contamination and the most appropriate soil sampling locations; e A phased site investigation including sampling and testing of soils for investigative and validation purposes; e Advising Mr Sherriff on the environmental quality of the site and the need for remedial works to allow for rezoning of the land, e A final phase of validation sampling on 16 April 1992. R6295.001 DAMES& MOORE4 of 44 Mr D Shemff - Environmentul Audit Report, Millgrove Page ii 29 May 1992 This report surmnarises the results of all of the investigations and testing carried out on the site, and contains the Auditor's Environmental Audit Report and the Certificate of Environmental Audit. The site is located approximately 76 km to the east of Melbourne and 2 lan west of Warburton. It is defined as Lot 1 on the Plan of Sub-Division No. 3553, Parish of Ywnga in the Shire of Upper Yarra on the Certificate of Title Vol. 8251, Fol. 668. The site is underlain by consolidated rock comprising siltstone and minor sandstone of the Humevale Siltstone Formation, and Rhyodaates of the Acheron Sub-Group, both of Devonian age. In the areas of lower topography adjacent to the Dee and Yarra Rivers, Quaternary age scree fan deposits and stream-deposited sediments comprising gravel, sand, silt and clay are present. The status of groundwater usage in the area is not known. However, the groundwater can be considered as having a beneficial environmental use. The property was purchased in 1959 by Mr Sherriff. During his ownership of the site, it has been used for agricultural purposes only and there is no evidence to suggest that the land has ever been used for industrial purposes by him or previous owners. Some use of pesticides was reported. A spotspraying method was used which was last conducted approximately 4 years ago. No other pesticides were used. Superphosphate was applied in previous years, but has not been used recently. 'Nocattle dip tanks are present on the property and according to Mr Sherriff, no dips have ever been used on the animals he has kept. Some disposal of wastes from the pig farming has taken place. Some small waste pits are present on the site. These were investigated for this report. This is the only evidence of any landfill on the site. More recently, waste effluent from the pigs has been spray-irrigated over the lower lying parts of the site to the south of the house and farm buildings, below the 145 m AHD contour. We understand that the pig sheds were washed down with water and that no chemical additives have ever been used for this purpose. A detailed inspection was carried out of all parts of buildings and of the surrounding land in order to idenw where any potential sources of contamination might exist on the site and to confirm the information supplied by Mr Sherriff. An aboveground tank remains on the site. However there have been no reported spills in the past. The area around the tank was inspected for indications of past spillage.
