Cecil, sleep well at night knowing that you are not throwing away good money by using a 110v system.

Charlie, you said that you are near Houston, Kelly Duffie is a national herbicidal co. rep in H town and may be interested in setting up something with microbes for experimentation and monitoring the cleanup process with aeration and his specific bacteria strains. I would also , as would many others, be intrigued with the results.
Maybe Kelly will weigh in, or you can send him an e-mail.
