Minneapolis

The City of Minneapolis released its 2017 Municipal Water Survey covering January 1 through December 31, 2017. This report aims to enhance public understanding of municipal water quality and raise awareness about protecting our vital water resources.

Understanding Your Water Source
Minneapolis municipal water comes from surface water drawn from the Mississippi River. The city strives to provide safe, reliable water that meets or exceeds federal and state quality requirements. Questions about Minneapolis water quality can be directed to 612-673-3000, where you can also learn about opportunities for public participation in decisions affecting water quality.

Water Safety Standards
The U.S. Environmental Protection Agency establishes safe municipal water standards that limit contaminant levels to ensure drinking safety. Similarly, the FDA regulates bottled water contaminant levels. Minneapolis routinely tests water for over 100 potential contaminants through collaboration with the Minnesota Department of Health.

Monitoring Results
The 2017 monitoring (January 1-December 31) detected no contaminants at levels violating federal standards. Some substances were detected in trace amounts below legal limits. The presence of contaminants doesn't necessarily indicate health risks. For information about contaminants and potential health effects, call the EPA's Safe Water Hotline (1-800-426-4791) or visit the Minnesota Department of Health's webpage.

Minnesota's Water Resources
Minnesota draws water from both groundwater (75%) and surface water (25%). Contamination can enter these sources from environmental factors and human activities. The five main contaminant categories include:

• Microbial contaminants (viruses, bacteria, parasites)
• Inorganic contaminants (salts, metals)
• Pesticides and herbicides
• Organic chemical contaminants
• Radioactive contaminants

Lead Awareness
Lead exposure can cause serious health problems, particularly for babies, children under six, and pregnant women. Lead rarely comes from water sources but can enter water through lead service lines and household plumbing. Minneapolis provides high-quality water but cannot control materials used in private plumbing systems.

Reducing Lead Exposure

1. Run water for 30-60 seconds before using it if unused for over six hours. With lead service lines, longer running may be necessary.
2. Use cold water for drinking, cooking, and baby formula preparation.
3. Consider water testing, especially for households with young children or pregnant women.
4. Install water treatment units if tests show elevated lead levels.

Water Conservation Tips

• Install low-flow plumbing fixtures to save gallons per use
• Fix leaks promptly – even slow drips waste 15-20 gallons daily
• Choose appliances with better "water factor" ratings
• Run washing machines and dishwashers only when full
• Water lawns efficiently using rainfall gauges and evening watering to reduce evaporation

Frequently Asked Questions

1. How often is Minneapolis municipal water tested?
   Minneapolis water undergoes continuous monitoring with comprehensive testing conducted daily, weekly, monthly, and annually depending on the specific parameters being measured.
2. What causes water hardness in Minneapolis?
   Water hardness results from naturally occurring calcium and magnesium minerals that dissolve in water as it passes through limestone and dolomite in the Mississippi River watershed.
3. How can I test my home's water quality?
   Residents can request water testing through the Minnesota Department of Health or purchase home testing kits from hardware stores. For lead testing, contact an accredited laboratory.
4. Does Minneapolis add fluoride to its water?
   Yes, Minneapolis adds fluoride to municipal water following state requirements to promote dental health. Levels are maintained within recommended ranges.
5. What should I do if my water appears discolored?
   Temporary discoloration often results from maintenance or hydrant flushing. Run cold water for 3-5 minutes. If problems persist, contact the water utility at 612-673-3000.
