How to Troubleshoot Mound Systems

It has been estimated that mound systems should perform hydraulically for 25 to 35-plus years. However, some systems do not perform as they should for that long. Soil treatment system problems are often traced to improper design and construction practices, but improper operation and maintenance of the system also contribute to problems with systems. In a 2004 study in Wisconsin, Blasing and Converse investigated mound toe seepage. Their results indicated that 80.8 percent of the samples had fecal coliform levels of less than 200 col/100 mL, which is the standard for swimmable and fishable waters. This data raises the question of
