Cold Weather Perc Test
Cold Weather Perc Test
(OP)
I was wondering if anyone has any tips on performing a cold weather perc test. We recently hit near-0 degree temps about a week ago and it has been consistently under freezing since. MT state DEQ allows two different test procedures, one of which allows the test to be run without a pre-soak period. The test should take about 1 to 1 1/2 hours to complete maximum. I will shoot for a day when its over 32 degrees, however, I'm wondering about the potential for frozen ground seeing how I am conducting the test 24 inches below ground.
Any help or comments are appreciated.
Thanks
