Jon Austermuhl, I would prefer to discuss this very important issue with you in a private e-mail discussion. I think that the standard US Public Health Service Method for performing soil percolation tests is so fallacious that it will yield incorrect results despite following the instructions exactly. The result is no more accurate if you do pay for an engineer’s trip to your island to perform the test. Send me an e-mail message to the following address:

I have developed an alternative percolation test method that is approved in Colorado, but I do not know if the test method will be approved in Alaska. It may be that you are not concerned with obtaining a permit for your system, but instead wish to know the correct percolation rate of the soil on your site for leach field sizing purposes. JWA
