Okun, Daniel A. – Environmental Science and Technology, 1975
Reorganization of authorities resulting in sound direction, greater flexibility, and more attention to cost effectiveness has helped the British achieve a high quality of water service. The history and development of British water management are reviewed and more cooperation between federal and state agencies is encouraged. (BT)

Environmental Science and Technology, 1974
Participants in the D-19 symposium on aquatic sampling and measurement for water pollution assessment were informed that determining the extent of waste water stream pollution is not a cut and dry procedure. Topics discussed include field sampling, representative sampling from storm sewers, suggested sampler features and application of improved…

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)

Environmental Science and Technology, 1975
The Second National Conference on Complete WateReuse stressed better planning, management, and use of water. The sessions covered: water reuse and its problems; water's interface with air and land, and modification of these interactions by the imposition of energy; and heavy metals in the environment and methods for their removal.

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)
