Divide Road Water Facility, Garfield County, Colorado
Dear Mr. Wilde:
We were requested to perform resistiv ity testing for the Divide Road Wate r Facility in Garfie ld
County, Colorado. We were requested to perform resistivity testing at the Generator Building ,
Storage Tanks and OAF Treatment Build ing sites . We conducted field resistivity testing for the
Generator Building and the Storage Tank area on June 28, 2013 and for the OAF Build ing on
July 17, 2013. Readings were obtained using a Nilsson 4 -Pin Soil Resistance Meter. At the
time of testing, the temperature was high 80's to low 90's with sunny conditions. Ground
conditions were dry for the Generator and Storage Tank sites and were very moist at the OAF
Building due to recent rainfall. The sites were barren of vegetation due to recent grading
activities . The tables below summarize our readings for each location.
