Environmental Science and Technology, 1975
Plants found in marshlands and wetlands in many parts of the world may play an increasing part in a very new, yet very old approach to treatment of water and wastewater--the application of biological methods. Biological water pollution control methods being utilized around the world are examined. (BT)

Schmidt, Richard K. – Environmental Science and Technology, 1976
Most waste treatment techniques conceived to meet the 1977 standards can be separated into three distinct phases: primary, secondary and tertiary treatment. An examination of the four heaviest industrial water users, pulp and paper, steel, plating, and food processing, demonstrates these treatments use proven technology to meet specific…

Gerba, Charles P.; And Others – Environmental Science and Technology, 1975
Increasing population and industrialization places heavy demands on water resources making recycling of wastewaters for domestic consumption inevitable. Eliminating human pathogenic viruses is a major problem of reclaiming wastewater. Present water treatment methods may not be sufficient to remove viruses. (MR)

Dahm, Douglas B.; And Others – Environmental Science and Technology, 1974
Spill control methods have been developed to control, treat and monitor spills of hazardous materials during their manufacture, transport, and storage. Spills on both land and water, and methods of treatment and control in these environments were studied. A discussion of detection and monitoring equipment and protective clothing concludes this…
