Recycling Treated Wastewater For Industrial Water Use in Minnesota MCES Project 070186 / LCMR 05-07d 5/1/07 Water Reuse Stakeholder Meeting April 24, 2007 Discussion Summary Technical Supply Issues/Public Perception 1. Technical issues are site specific and variable. 2. Example provided of the SMSC plant a. 2 trains with different treatment to meet different end quality requirements b. Aquifer recharge is an ongoing discussion 3. All points noted in the Implementation Considerations table need to be considered. Public Education – not addressed earlier 4. The topic of public awareness is critical to address in the implementation of water reuse practices in Minnesota. 5. The Minnesota public needs to be aware that reuse is for the good of the environment and that health concerns are addressed. 6. Reuse is an opportunity to be of benefit to the environment. 7. Public involvement process must begin early – up-front in the planning process need to involve community. 8. Issue for some – is this going into the tap water? 9. Consider TCAAP and Riley Tar – contaminated supplies are being treated and used by the communities. Community was educated on the treatment process and accepting of technology to use the supply. Cost was covered by federal funds for site cleanup and remediation. 10. Similar public perception issue seen with biosolids. Some communities are not allowing biosolids applications on their fields. 11. California regulations are based on significant studies. These can serve as sources to show the public the extent of scientific research that has been done in the development of regulations and related risk assessments. 12. Reuse can be part of our environmental ethic. 13. In other similar efforts to promote an environmental issue or treatment technology – it took one person or agency to take the lead. A similar model could work for water Page 7 of 8

Also, implementation could target one industry sector and gain acceptance from that type industry and type of water uses. 14. The Office of Environmental Assistance and their mission appear to align with the conservation basis of water reuse. Can they become involved? Page 8 of 8
