ABSTRACT
But if site and soil conditions are not good, the difference between chickens and experts may become quite obvious after a while. For instance, I have just visited a large sewage disposal site for a residential development in another county. Black septage is oozing out of the soil at the lower portions of a concave 10-acre basin, and is forming a mosquito-laden swamp. The septic system was designed by a major engineering company, which tested the upper 2 feet of a thin (8-foot) soil mantle over impermeable bedrock, and concluded that the site was quite suitable for leachlines.
