SAFETY CONSIDERATIONS <br /> Can I swim?Can my dogs swim?What if my dog drinks lake water? <br /> The short answer is yes,you and your dogs can swim. Health risks from alum are VERY low. <br /> • Alum sinks quickly to the bottom. Coming in direct contact with the alum is very low. <br /> • There are no restrictions on swimming or using water to water plants/lawn <br /> • No permit is needed from Minnesota Department of Natural Resources or the Minnesota Pollution Control <br /> Agency to apply alum <br /> Other Considerations: <br /> • Alum is used often in our drinking water treatment plant process.St. Cloud,St. Paul, and various other cities <br /> across Minnesota use this in the process of clean drinking water <br /> • Alum is the primary ingredient in the OTC antacid Maalox <br /> • Aluminum is found in many foods <br /> Are there any long-term health concerns for humans? <br /> The American Alzheimer's Association says there's no link between aluminum sulfate and memory loss(a common <br /> myth).Sources: https://www.aLz.org/alzheimers-dementia/what-is-alzheimers/myths and <br /> https://www.atzdiscovery.org/cognitive-vitality/blog/is-there-a-link-between-aluminum-and-alzheimers <br /> Does it hurt fish and aquatic life? <br /> When used appropriately,there is a VERY low risk to fish. Aluminum toxicity is a concern for fish when too much alum is <br /> applied too fast. RCWD will make sure this is not an issue and alum is applied correctly. Minnesota Pollution <br /> Control Agency guidelines for alum application require that the pH remain within the 6.0-9.0 range. <br /> COMMUNITY INVOLVEMENT <br /> How can I support this project and other water quality work? <br /> Attend all public meetings regarding this project.
