Detroit Tap Water: Safety, Quality, and Concerns
Detroit tap water generally meets or exceeds all federal and state safety standards. However, historic issues and infrastructure concerns have led to lingering questions about its quality and safety. The city has made significant investments in its water system, but transparency and public trust remain crucial.
Is Detroit Tap Water Safe to Drink?
According to the Detroit Water and Sewerage Department (DWSD), Detroit’s tap water is safe to drink. DWSD regularly tests the water supply to ensure it complies with the Safe Drinking Water Act (SDWA) standards set by the Environmental Protection Agency (EPA). These tests cover a wide range of contaminants, including lead, bacteria, and other harmful substances.
What About Lead Concerns?
Lead contamination has been a major concern in Detroit due to the presence of lead service lines connecting homes to the water mains. While the DWSD adds orthophosphate to the water to create a protective coating inside pipes and prevent lead from leaching, some older homes may still experience elevated lead levels. The city has been actively working to replace lead service lines and encourages residents to flush their water before drinking, especially after periods of non-use. More information about lead in drinking water can be found on Wikipedia’s article on Lead contamination in drinking water in the United States.
How is Detroit Tap Water Treated?
Detroit tap water undergoes a multi-stage treatment process at the city’s water treatment plants. This process typically includes:
- Coagulation and Flocculation: Chemicals are added to the water to clump together impurities.
- Sedimentation: The clumps settle to the bottom, allowing for removal.
- Filtration: Water passes through filters to remove remaining particles.
- Disinfection: Chlorine or other disinfectants are used to kill bacteria and viruses.
- Fluoridation: Fluoride is added to help prevent tooth decay.
- pH Adjustment: Adjustments are made to maintain optimal water chemistry.
Where Does Detroit’s Water Come From?
Detroit’s primary water source is the Detroit River, which is part of the Great Lakes system. The DWSD also has the ability to draw water from Lake Huron during peak demand or emergencies.
FAQs about Detroit Tap Water
Is Detroit tap water hard or soft?
Detroit tap water is considered moderately hard. The hardness can vary slightly depending on the time of year.
Does Detroit tap water have a funny taste or smell?
Occasionally, residents may notice a chlorine taste or smell, which is a result of the disinfection process. This is generally harmless and dissipates quickly.
How can I test my tap water for lead?
The DWSD offers free lead testing kits to residents. You can request a kit through their website or by calling their customer service line.
What should I do if I’m concerned about the quality of my tap water?
Contact the DWSD immediately. They can provide information about recent test results, investigate potential problems, and offer advice on how to address concerns.
Is bottled water better than Detroit tap water?
While bottled water is a convenient option, Detroit tap water consistently meets all federal and state safety standards. Drinking tap water can also be more environmentally friendly and cost-effective.
Summary
Detroit tap water is generally safe and meets regulatory standards, thanks to significant investments in infrastructure and treatment processes. While past issues with lead and ongoing concerns about transparency necessitate vigilance, the DWSD actively monitors water quality and works to address any potential problems. Residents are encouraged to stay informed, request lead testing kits if concerned, and contact the DWSD with any questions or issues.
