<br />~~ <br /> <br />5.2 Environmental Monitoring Schedule <br />Cotter proposes to conduct the background baseline testing, as well as <br />the one-time studies, listed below. <br />5.2.1 Vegetation <br />The purpose of this study is to determine the levels of radium and <br />uranium in several plant species which are common to the four locations selected. <br />Three sites have been selected relative to the waste pile: upstream; adjacent <br />thereto; and downstream. A fourth site will also be sampled at the Long Lake <br />headgate. (See Figures 1.1-1 and 1.1-2.) <br />Several species occur at each site. They have been tentatively identified <br />as Kentucky bluegrass, C~oldenpea Cliffrose, and Willow. Cheatgrass is also <br />prevalent at these sites. <br />• Sampling will be done semi-annually in the spring and fall. Of the <br />plants clipped at each site, one-half of the samples will be washed in a weak <br />nitric acid solution to remove dust. A11 samples will be analyzed f~~r Ra-226 <br />and V. <br />5.2.2 Soil <br />Soil samples will be collected at various depths in conjunction with the <br />vegetation sampling, and will be analyzed for Ra-226 and U. <br />5.2.3 Other Vegetation and Soil Sampling Considerations <br />The analyses outlined below may be conducted at a later date to provide <br />additional data, or as research dictates. <br />1. Vegetation -Sample plant parts independently. <br />- Various times of year <br />- Establish control sampling site outside of the <br />four sampling sites identified above. <br />- Literature search for selective accumulators <br />• (plant species) sampling methods, etc. <br />2. Soils pH, texture, conductivity. <br />5-2 <br />
