Refuse Analyses indicate that <br />the material is highly sodic and moderately saline. Diffusion of sodium salts <br />into replaced cover soils could possibly occur, depending on characteristics <br />of the cover soil. It would be prudent to sample incremental cover soil <br />depths upon completion of test plot construction so that any upward movement <br />of sodium over time could be monitored. Parameters could be limited to <br />textural analysis, electrical conductivity and sodium adsorption ratio. <br />I will be interested to see how closely the enclosed analyses compare to the <br />sample splits which Tim Chervick submitted for analysis. <br />Please contact me if you have any questions, <br />Since ly~ <br />Dan T.
