[Adopted 12-17-1985, effective 12-22-1985 (Section 9.00 of Part VIII of the 1991 Codification as updated through 6-1-1996)]
The filling of marginal lands in close proximity to groundwater in order to provide for sufficient area to make it suitable for the installation of a sewage disposal system is not considered an acceptable practice and such lands are considered as not suitable from a sanitary point of view for human habitation and for the protection of groundwater and watercourses. Watercourses are defined in Regulation 15.01, of 310 CMR 15.00, the State Environmental Code, Title 5, Minimum Requirements for the Subsurface Disposal of Sanitary Sewage.
Subsurface sewage disposal systems shall be located in an area where there is at least a four-foot depth of naturally occurring pervious soil below the entire area of the leaching facility and the designated leaching reserve area. This four-foot depth of naturally occurring pervious soil must be above maximum groundwater elevation.
The maximum groundwater elevation shall be determined by utilizing the formula contained in the United States Department of Interior Geological Survey publication, "Estimating Highest Groundwater Levels for Construction and Land Use Planning - a Cape Cod, Massachusetts, Example," dated September 1983, or by observing the height of the groundwater table when it is at its maximum level or elevation. Maximum groundwater determinations shall be made during the wettest season of the year, normally March or April. Allowances shall be made for high water level if the Board of Health permits the determination to be made outside the wettest season.
