Requirements #l5 (Determine safe distances from water supplies), #l6 (Methods of sampling at aquifer interface), and #l9 (Effect of wastewater injection on groundwater quality) are to be covered in discussions with other cognizant Research Committees. At this time there is no one Committee with central responsibility in the groundwater area. A parallel look at this issue with regard to landspreading of sludge is recommended as a new initiative, described earlier, in Municipal Sludge Management. Requirement #l7 (Design criteria, cost of evapotranspiration systems) may be addressed by on-going research projects but additional discussions are needed with the Regional Office (Region I) to ascertain the applicability of the efforts. AQUACULTURE PROGRAM The l972 Act (PL 92-500) and the l977 amendments clearly give impetus to the development and use of aquaculture treatment of municipal wastewater. Agency Research Requirements, Priorities, and Future Directions Wastewater aquaculture is a viable research area having large potential for application to environmental problems. In order to develop processes for wastewater treatment or reuse, however, it will be necessary to evaluate a variety of criteria such as loading, pretreatment requirements, stocking and harvesting rates, product processing and utilizations, acceptability of species, climatic factors, and economy of operation. Wastewater aquaculture is very broad in scope, involving a variety of organisms, both freshwater and marine environments, organized treatment processes, and wastewater recycling by inputs into natural aquatic habitats.
