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.

In order to adequately assess the impact of power plant cooling water intake on an aquatic ecosystem, total ecosystem effects must be considered, rather than merely numbers of impinged or entrained organisms. (Author/RE)

A recent conference of the National Environmental Development Association focused on the concepts of environment, energy and economy and underscored the necessity for balancing the critical needs embodied in these issues. Topics discussed included: nuclear energy and wastes, water pollution control, federal regulations, environmental technology…

Legal regulations of thermal pollution caused by the introduction of waste heat into our water resources and the potential of this energy as a future resource are discussed. (CP)

Using 1000 MW coal-fired central power stations as an example, the impacts upon other media (land, air, water) are analyzed when controls are imposed on one medium. The development of a methodology for assessing the cross-media impact of specific control technologies or strategies is illustrated. (Author/BT)

Describes technologies used to conserve energy by using process wastes in the following situations: (1) incineration at a photographic company, (2) wet oxidation at a paper mill, and (3) sewage skimmings fuel at a municipal waste water plant. (MA)

Energy needs for environmental cleanup are assessed. Among the conclusions are: the quantities of energy required to achieve various environmental quality goals are small; energy needs for environmental protection can be offset by conservation measures and the conclusions in regard to primary energy closely correspond to those for electrical…
