SAFE WATER investigation (from http://www.sciencetakeout.com)
An infant is admitted to the hospital with serious symptoms. The infant’s family recently moved to a house with a private well, not a public water supply. You will test the water from their well for three potential contaminants that could be causing the baby's symptoms—coliform bacteria, nitrates, and arsenic—and determine whether the concentration of each contaminant is safe or unsafe. And then... The family moves to a house with a public water supply and must consider whether to use tap water or bottled water. Which choice would you make now? Will you recommend a different choice after testing samples of the town tap water and bottled water? |
