Out of Sight, Out of Mind: The Hidden Reality of Groundwater as a Drinking Water Source (Webinar)
Thirty percent of our planet’s fresh water is stored below the Earth’s surface as groundwater, and approximately 145 million Americans get their tap water from these groundwater sources. However, groundwater quality is sometimes overlooked because the water isn’t visible to us all the time like our rivers and lakes are. The Earth can often naturally filter and clean water as it infiltrates through soil and rock, but there are some contaminants that still make it through, and not every groundwater source is created equal when it comes to water quality.

Your kit will include a bottle containing 25 nitrate test strips which you can use to test your water source(s) throughout the year. You’ll also receive postcards explaining how to use your nitrate test strips and how to share your Nitrate Watch results on the Clean Water Hub.
Your kit will include four test strips so you can test your waterway throughout the season. You’ll also receive a chart to help you interpret your results and a postcard with instructions for completing a Salt Watch test and reporting your findings.
