Today we visited the Parker Tract site and excavated three test holes with a backhoe.
The site inspection was performed by Vincent Lewis (NCDENR), Linda Lewis
(NCDENR), James A. Parker (owner), Michael R. Kersting (architect) and Charles
Cazier (engineer). See enclosed plan for location.
Test Hole No. 1: Found to have a shallow water table. The proposed bottom system
to be at natural grade.
Test Hole No. 2: Found to have a shallow water table. Did not suggest this area for
inlfiltration.
Test Hole No. 3: Light gray sand with a SHGWT at 4.5' (elevation 37.0). Bottom
of trench to be at elevation 39.0.

Dear NIr. Parka:

As requested, S&NM personnel have recently conducted two double -ring irdltrometer tests of the
shu5cial soils at the subject site st the approximate locations shown in Figure 1. Specifically, our
representatives performed the following work items on October, 21 2004.
1. Advanced one haled-augered boring near each intfiItrometer test location in
order to visually classify the in -place soils. A Munsell Soil Color Chart was
used to define the but and chroma of the recovered soil samples.
2. Conducted two double -ring inblttometer tests at depths rat>Iging•fivm 4 inches
to 5 ind%es below the existing ground surface. The root rust and organialaden
soils were rernovcd in order to perform our tests on the in -place sands. This
testing was conductcd in general accordance with American Society for Testing
and Materials (ASTM) procedure D-3385 entitled, "infiltration Rate of Soils in
Ficld Using Double -Ring Infilt vantter".
Based on our field classifications of the excavated soils at the bzW-augemd boring locations, the in -
place soils consist of slightly sihy sands. These soils extended to the maximum completed boring
depth of 48 inches below the existing ground surface. Water was encountered in the boreholes near
the double -ring mfilh=neter test locations at depths ranging from 21 to 44 inches below the existing
ground surface. The site water level will flwtuate with climatic and seasonal conditions, however,
and may be higher or lower at other times of the year. The U.S. Depardnent of Agriculture Soil
CoAservation Service publication entitled, 'Soil Survey of New Hanover County, North Carolina",
indicates that the seasonal high vmw table occurs within 12 inches of the ground surface at this site.

The average infiltration rate at tut Iocedon 1 was approxiamely 5 inches per hour. At test location
2, the average infiltration rare was approximately 15 inches per hour. A surnaury of ft field test
results is presented in Tables 1 and 2.
