Chicago Water Quality Tests
Each test will be done with the 4 samples collected on Monday.
- Ammonia Nitrate - nitrates in conjunction with phosphates stimulate the growth of algae
- pH - solutions in pH range of 4-9 are not considered hazardous
- Chlorine -disinfecting agent
- Chromium - enters a water supply through discharges of industrial wastes - potential carcinogen
- Copper - essential element to the human body; large does are harmful, causing liver damage
- Cyanide - extremely toxic - found in water containing waste from metal finishing
- Iron - high levels indicate water contaminated by acid mine wastes
- Phosphorous - stimulates the growth of algae
- Silica - some scientists prefer not to see this in water
- Sulfide - rotten egg ordor in high concentrations
Students noticed that water closer to the city center smelled better and has less toxic chemicals in it.
