RE: Groundwater Monitoring
Wyndmoor
Dear Mr. Groves:
Construction Materials Engineering & Consulting, PC (CMEC) has conducted the ground water
monitoring of two (2) hand auger locations within the proposed sand filter area on June 13, 2014. The
location of the test pits are shown below. The sand filter shown was moved based on results of the
ground water testing provided on June 17, 2014.

Hand Auger 41 was located near a drainage feature. The Hand Auger is on the bank of the drainage
feature. The existing ground elevation is 639.7. The bottom of the test pit is approximated at 8 feet.
CMEC returned 3 days after the initial hand augers. At this time, water was measured 43 inches below
existing ground. The' approximate elevation of the water was 636.12.
Hand Auger #2 was located between trees labeled 342 and 370. The existing ground elevation is
638.3. The bottom of the test pit is approximated at 7 feet. CMEC returned 3 days after the initial hand
augers. At this time, water was measured 75 inches below existing ground. The approximate elevation
of the water was 632.05.
The elevations provided are based on relative grades by Phoenix Land Surveying. CMEC believes the
water elevation in the boring holes represent the watertable forthis area. There is an existing drainage
feature which could impact future groundwater elevations. Therefore, the sand filter was adjusted away
and slightly up gradient as shown in the above image.
If you should have any questions, please call me at your convenience 704-361-8104.
Sincerely,
