Some newer delegates and visitors to the CCANSW website may not be familiar with Body Dent's thesis "THE HYDROGEOLOGICAL CONTEXT OF CEMETERY OPERATIONS AND PLANNING IN AUSTRALIA".
The purpose of this research has been to evaluate the potential contamination impact of cemeteries on groundwater. A comprehensive study of the groundwaters in the unsaturated and saturated zones of nine Australian cemeteries has been made, with most sampling between October 1996 and August 1998. Periodic sampling from 83 wells or ponds yielded 305 complete samples which were tested for at least 38 inorganic and 5 bacterial analytes. Other, partially complete samples were used for metals and bacterial analyses. The soils of all sites were tested for a range of analytes that might reflect or affect the presence of human decomposition products.
I have linked the document to an article in the CCANSW F.A.Q. section.
