SUBJECT: Percolation Test - Lot J3~ Block D~ Rolling Hills
Estates
Dear Mr. Formenfo:
A percolation fast was performed in fha excavation next
fo fha perforated concref~ distribution unit on 16 August 1962.
The soils tog percolation date and approximate loceflon of fha
fesf are shown on fha attached sheet,
The percolation rate was I inch per 3 mlnufeso
You will note fhaf fha percolation test does not ret|ecl
fha soils ~xposed in the sides or bottom o~ the excavafton~ but
rather a strafe which begins af ~pproxtmafelv 6 inches below
fha present bottom and extends ~f least another 4 feet in fha
spot fast drilled. The soils exposed in the trench sides and
bottom may be ¢×p¢cfed fo have a Io.~ rate of percolation. No
Indication of fha wafer fable wes noted fo the fatal depth
exposed.
~e recommend that you ask fha chief sanitarian tf if
would not suffice fo deepen fha excavation fo fha clean sand
and backfill with a clean granular soil within the limits of
present excavation.
Ground wafer conditions~ soils, and percolation rates
as reported Indicate fha conditions existent af the specific
time and Iocaflon fha test was performed. ~¢ cannot predlcf
the conditions ~hich may exist af any other flm¢ or af any
other location.
Very truly yours~
