What is needed is an alternative approach which permits development of valid cause and effect relationships. This strategy, one involving intensive surveys, is referred to here as mechanistic. The Willamette River, Oregon, USA, is used as a case study to illustrate quantitative, semi-quantitative and qualitative approaches to mechanistic assessment of river water quality using, respectively, dissolved oxygen depletion, erosion/deposition and potentially toxic trace elements as examples. 

The Willamette River Basin, Oregon serves as an excellent case study of river quality assessment for a number of reasons. First, the Willamette River has been cited internationally as a classic example of how water quality can be restored from a previously poor quality waterway (1-3). Second, excellent background data were available, particularly on hydrology. Third, at the time most of these studies were initiated, the Willamette River was the largest river in the U.S. for which all point-source discharges were receiving secondary wastewater treatment. 

The results of map generation cannot be expressed effectively with the format available here. However, the State of Oregon utilized the map and matrix techniques in their nonpoint source evaluation and as a basis for designing more intensive survey approaches to assessing the impact of human activity on river quality. In addition to reflecting deposition of sediments, the methods can be applied to transport of pesticides, nutrients and trace elements since many of these substances tend to adsorb to the organic and inorganic fractions of soil. 

Methods. As discussed in the previous chapter, a number of approaches have been used to assess the presence of potentially toxic trace elements in water. The approaches used in this assessment include comparative media evaluation, a human health and aquatic life guidelines assessment, a mass balance evaluation, probability plots, and toxicity bioassays. Concentrations of trace elements were determined by atomic absorption spectrometry according to standard methods (21,22) by the Oregon State Department of Environmental Quality and the U.S. Geological Survey.

This technology is currently commercially available. SR2 has permits to operate LTTD plants in 11 states Arizona, Arkansas, California, Georgia, Idaho, Nevada, New Mexico, Oregon, Texas, Utah, and Washington. Permits to treat chlorinated hydrocarbons have been issued by Arizona and the South Coast Air Quality Management District (SCAQMD) in California.

The Oregon installation uses a 25 tire per hour unit manufactured by Nippo in Japan and marketed in the U.S. by Tsurusaki Sealand. The unit has been in operation since 1987 with moderate success, but no U.S. company has yet decided to purchase another one. The draft configuration in the unit allows it to bum at 2,000 degrees Fahrenheit and produce 100 psig process steam. The unit has a Cleaver Brooks waste heat recovery boiler and a bag filter. Whole tires are automatically fed into the unit-both automobile tires and light truck tires. The State of Oregon Department of Environmental Quality has approved the operation of the unit.

Wines have been produced east of the Rocky Mountains since the sixteenth century. More wine was produced there than in California until 1880. The specific climatic conditions and the varieties used in this region are different from those of California, Washington, or Oregon. Not only are the varieties different but their ripening is, too. This has resulted in a type of wine production that is different from that used elsewhere. These production procedures are evaluated with special regard to the introduction of new varieties and to renewed interest in wine quality. 

The Oregon Department of Environmental Quality (ODEQ) has incorporated by reference the federal RCRA regulations for identification and listing of hazardous wastes (Oregon Administrative Rules 340-101-001). In addition to the federally listed acute hazardous wastes, ODEQ regulations include the following as state-specific listed hazardous wastes ... 

The Oregon Environmental Quality Commission issued a permit (ORQ 000 009 431) to the U.S. Army, as represented by the Umatilla Chemical Depot and the Washington Demilitarization Company, LLC, to operate a hazardous waste treatment and storage chemical demilitarization facility located in Umatilla County in Hermiston, Oregon, off Interstate Hwy-84 at exit 177.
