"I did spear with Ms. Stevens before and she questioned the method <br /> and rationale behind the adjustments." "All I can say is that I verified the adjustments <br /> with the Cape Cod Commission." "Ms. Stevens engineer adjusted it at I V and <br /> according to the Cape Cod C onunission 3.1' is not accurate it should be adjusted up to <br /> 3. ' which would make this property unbuildable because you don't have the ' of <br /> naturally occurring permeable soil between the bottom of the leaching facility and <br /> groundwater." "At few years back the a j anent abutting property had a sudden failed <br /> system due to high groundwater." "There was what appeared to be an impermeable layer <br /> about 3' or 4' down and the system was below that and blew out through the peat layer <br /> and onto the ground surface," "This is an extremely difficult area, as fax as septic systems <br /> go in meeting Title v and our local regulations."

"The biggest problem with mounding a system is that <br /> typically, you still have the underlying problems which is the clay layer." "You really <br /> haven't alleviated the problem you just moved it up so you just have ' of soil underneath <br /> xt.151 "Even if you were to dig it out and fill it in with clean material your still 1n this big <br /> field of clay."
