They are PH value, temperature and <br />conductivity. According to this report, it is apparent that all <br />parameters are within the effluent limitations for discharge, except <br />for Magnesium (Mg), which is 370 mg/1. I do not know if this figure <br />is beyond the effluent limitation or not beca~!se it was not one <br />required by EPA. <br />I await your advice. <br />Sinc rely, i <br />- /< <br />L. K.
