Served as expert witness in a case involving the failure of a leach field of a septic tank system at a very large single-family home shortly after the leach field was constructed. While channeling the overflowing sewage away from the residence, the home owner contracted Giardia Lamblia and was banned by health officials from working for six weeks at his normal job, which involved food preparation. Investigations revealed that the Contractor had not followed the requirements of the County Health Department and had constructed less leach line than was offered in his proposal.
