In covered lagoons, which are less efficient than fixed-film anaerobic digesters, the digestive bacteria float around, making only random contact with the manure particles. In fixed-film digesters, the bacterial growth occurs on the surfaces of the internal media that the waste must flow over, thereby assuring frequent contact. In this way, higher volumes of wastewater can be processed.
We're convinced it's not a human-induced condition but a natural condition brought on by wetlands and ground water. We'll recommend a re-classification of that stretch of the river so that it won't be encroached upon by human activity. It could not support a wastewater treatment plant, for example.
These communities have done an excellent job of removing pollutants from wastewater and complying with their permits to the degree they've been able to help expand local recreational opportunities. These communities, the operators of the facilities, and city leaders all have a right to be proud of their commitment and performance in carrying out this important responsibility.
One of the essential services a society requires is provision of fresh water and disposal of wastewater. Being involved in this industry, we are in a public health and environmental issues, so I consider myself an environmentalist and a conservationist, and that is a great satisfaction I get from doing this.
