This paper will explore how information played an important role in the history of the Hanford site. Looking closely at Environmental Protection Agency (EPA), Department of Energy (DOE), and other government agency publications and documents will bring more insight into the effects on the environment and how the government has handled the situation throughout its operations. This paper will also add non-governmental perspectives on the issues presenting news reports and evidence that call attention to the problems.

Neonicotinoid Pesticides

Abstract Among pesticides and foliar sprays involved in the treatment of seed, soil, and grass, also to crops, an important group is neonicotinoids. Neonicotinoid pesticides present similar properties with nicotine, but the mentioned compounds are less harmful for humans. Nevertheless, neonicotinoids are poisonous to insects and some invertebrates, which can act against insects’ central nervous system, leading to their death. Moreover, neonicotinoids can affect the reproduction, foraging, and flying ability of honeybee and other insects including pollinators. In the present study, some neonicotinoids, such as imidacloprid, acetamiprid, clothianidin, thiacloprid, and thiamethoxam together with their toxic effects, have been presented. The Environmental Protection Agency (EPA) classifies these neonicotinoids as II and III class toxicity agents. Due to accumulation of these pesticides into the pollen of treated plants, especially due to their toxic effects against pollinators, the consequences of the occurrence of these insecticides have been discussed. Analytical aspects and methods involved in the isolation and determination of this class of pesticides have been presented in this contribution.

Transfer Programs

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 City

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.
