Neither of these reagents <br />is anticipated for treatment of the water at this time. This information is being provided <br />in the event that the water chemistry changes. <br />4.4 Environmental & Operator Safety <br />Materials Safety Data Sheets (MSDS) for each of the two designed reagents and those <br />additional reagents that could be added can be found in Appendix B.
