This program illustrates the physical, biological, and chemical treatment processes required to decontaminate industrial and residential wastewater and describes ways in which discharge is being put to work. Two wastewater treatment facilities are toured—one a traditional bricks-and-mortar operation and the other a constructed wetland system. Also, Steve Woods, of the Bayou Marcus Water Reclamation Facility; Thomas Byrom, of the Galveston Bay Estuary Program; and many others praise innovations such as high-tech disinfection and using treated wastewater to recharge aquifers while at the same time voicing concerns over funding difficulties and violations of the law.
