TO: File - 2100 Webber Hills Road <br /> FROM: Stephen Weckman, On-Site Systems Manager <br /> DATE: July 9, 1993 <br /> SUBJECT: Septic System Inspection on June 7, 1993 <br /> A septic system inspection was scheduled for 2100 Webber Hills Road at the request of the <br /> realtors with regard to the sale of the home. Prior to the on site inspection, they were informed <br /> that the property lies within the shoreland district and is subject to the recently adopted <br /> Shoreland Regulations, which require soil borings to identify the separation from the sewage <br /> treatment device and the seasonally high water table as identified by mottling. <br /> I met both realtors on the site on the morning of June 7, 1993 for the septic inspection. As we <br /> walked across the site to the septic system, I explained the history of the septic system inspection <br /> program and the system classification history up until this inspection. The system has been <br /> classified as a substandard system in 1978. As it was apparently installed according to the codes <br /> enforced at the time of installation, it is not an illegal system such as a cesspool, and was not <br /> observed to be discharging effluent to the surface. <br /> Once the drainfield trenches had been identified, I took soil samples while I explained the <br /> DNR's new requirement of the 3' separation between the sewage treatment device and the <br /> seasonally high water table as defined by mottling. <br /> After examining each of the samples, they were passed on to the two realtors to examine and <br /> I pointed out examples of mottled soil. The first soil boring revealed prominent mottling at 4' <br /> and I explained what is considered prominent mottling. I then showed them my soil probe, <br /> which identified the first trench. The top of the trenches was found to be 2' below the surface <br /> and the trench bottom would then be at least 36" deep. I explained then that the system only <br /> had a 6" separation from the system to the water table and is clearly nonconforming, requiring <br /> replacement within one year. A second soil boring was then performed to confirm the result of <br /> the initial boring. This second soil boring revealed mottling at 30" with the trench depth at 36" <br /> still. This portion of the system would therefore be within the water table. <br /> As we were leaving the site, I asked if they had any questions. There were no questions and <br /> I left the site. <br /> ch <br />
