What’s In Our Water: The Science of Water Quality and Testing

March 12 @ 10:00 AM - 11:00 AM PST


Liquid water is so essential to life as we know it that when we look for life beyond our planet we always look for water. What is it about water that all life on Earth needs it?

What is ‘pure’ water? Is water without anything in it safe to drink? What is the difference between distilled, filtered, and purified water?

What substances may be found naturally in water? What is the difference between contaminants and pollutants and what are their sources?


The Hydrologic Cycle


From where do we get the water we use? What kinds of tests are conducted to measure the quality of that water? How often should these tests be conducted? What is the science behind different kinds of water quality tests?

How is the quality of water determined? What are the health limits for different organisms of having different natural and introduced substances in the water in which they live or drink? Who determines these limits?

What are the human health effects of having certain substances in the water we use for recreation or consumption?

Come join us to have these questions answered and hopefully answer others you may have about the life-sustaining substance we call water.
