On August 19-20, 1990 an additional alternate septic
system area was tested to the east of the former alternate
area. This is because of the grading traffic over the former
alternate area and the risk of compaction of those soils.
This new area was relatively undisturbed and had re
sults from the percolation testing and soil borings which
would be acceptable for a mound system should the need ever
arise. This area must be kept undisturbed. It would also
be wise to keep the present undisturbed area northeast of
the house as is for another potential site.
Additional information follows, if anything else is
needed, please notify us.
Sincerely,
PERCOR, INC.
