The water supply in Denver, as highlighted by the Environmental Working Groups Tap Water Database, raises concerns due to elevated levels of ten cancer-causing chemicals, such as Arsenic, Chloroform, Dichloroacetic acid, Radium, and others. The presence of these substances underscores potential health risks associated with drinking tap water. It is crucial for residents to be aware of these findings and consider alternative water sources or invest in water filtration systems to ensure the safety and well-being of their households.
