Ground water, a hidden resource whose volume is over 50 times that of the nation's surface water, was once thought to remain forever pure. People had little reason not to believe that the soil would naturally purify water returning to an aquifer. It was not until the late 1970s when the Love Canal and Times Beach incidences redirected public opinion and touched off a nationwide concern for the protection of ground water. In August 1984, the Environmental Protection Agency (EPA) issued a Ground Water Protection Strategy to "provide a common reference for responsible institutions as they work toward the shared goal of preserving, for current and future generations, clean ground water for drinking and other uses, while protecting the public health of citizens who may be exposed to the effects of past contamination."1 More specifically, "EPA will increase efforts to protect ground water from pesticide and nitrate contamination." In response, the EPA's Office of Pesticide Protection reviewed existing information on the extent and causes of pesticide contamination, its potential health hazards, existing statutory authorities, and programs available to aid state policy makers. An increased interest in solving problems associated with pesticides in ground water has resulted in the EPA's current development of a national strategy on Agricultural Chemicals in Ground Water. This strategy will outline the EPA's general course of action in addressing the problem of pesticides in ground water during the next 5 to 10 yr. The purpose of this report is to provide EPA with suggestions to be considered in the formulation of the strategy.

In spite of the economic benefits of insecticides to farmers and consumers, growing concern about the potential health and environmental hazards of some insecticides has resulted in the investigation of many insecticides by the Environmental Protection Agency (Boraiko). The use of several insecticides has already been banned. Others are under review and their use may be banned or restricted in the future.The Environmental Protection Agency must evaluate, monitor, and regulate a wide range of chemical compounds. To do so requires the collection and analysis of information on the environmental, health, and economic impacts of the use of many diverse chemicals. Though regulatory action by the Environmental Protection Agency may reduce health and environmental risks, such action can also alter the profitability and performance of a farming operation.

Technology transfer is an important activity within the ll.S. Environmental Protection Agency. Specific technology transfer programs such as the activities of the Center for Environmental Research Information, the Innovative and Alternative Technology Program, as well as the Small Community Outreach Program are used to encourage the utilization of cost-effective municipal pollution control technology. Case studies of three technologies including a plant operations diagnostic/remediation methodology, alternative sewer technologies and ultraviolet disinfection are presented. These case studies are presented retrospectively in the context of a generalized concept of how technology flows from science to utilization which was developed in a study by Allen (1977). Additional insights from this study are presented on the information gathering characteristics of engineers and scientists which may be useful in designing technology transfer programs. The recognition of the need for a technology or a deficiency in current practice are important stimuli other than technology transfer for accelerating the utilization of new technology.

The Hornsby Bend Hyacinth Facility, the first such system built under the U. S. Environmental Protection Agency “Construction Grants Program”, represents the culmination of over a decade of experience at the City of Austin with hyacinth treatment. The facility consists of three culture basins 265 m in length with an area of 1.6 ha. To permit year-round hyacinth culture, basins are covered with a 2.06 ha unitary greenhouse structure. Fenced exclusion areas at intervals along sides of basins serve as natural aerators and enhance fish production. The system, operated in an aerobic mode, was designed to daily treat about three million liters of sludge lagoon supernatant. Exclusion of large vertebrate predators and stocking of basins with selected animal species will provide a unique ecosystem. Basins were planted with hyacinth in late October, 1985 and discharge commenced on February 3, 1986. Functional characteristics and ecological considerations of the facility are discussed and operational performance data are presented. Maintenance harvesting of hyacinth and disposition of plant material are described. Application of greenhoused hyacinth treatment systems are addressed.
