We have indicated the OUL number for each of these <br />samples on the enclosed table. <br />The fluorescein dye wncentration is based upon a standard routinely used at the <br />OUL. It is a mixture of 75% dye and 25% diluent, and the concentration is based upon <br />the as-sold weight of the dye. <br />The fluorescence intensity of the tracer dye can decrease at low pH values such as <br />may be encountered in coal mine azeas. Your water samples aze routinely analyzed <br />undiluted, and then mixed with an equal volume of the OUL eluant to ensure that the pH <br />will always be in excess of pH 7, and analyzed again. <br />(cont'd) <br />Water and Land Use Investigations in Soluble Rock Terrains <br />
