What are the possible or probable environmental consequences of applying municipal wastewater to wetlands. Here, 31 papers address this question from various perspectives. Coverage includes: state-of-the art engineering for applying wastewater to wetlands; environmental values and perspectives; ecosystem dynamics - particularly hydrology-nutrient interactions; human and wildlife environmental health problems that could result from wastewater applications; case histories of the long term effects on wetlands that received wastewater or simulated wastewater for several years; and wetland management potential.
