What does it mean to have safe drinking water? What does water conservation really entail? According to the US Environmental Protection Agency, there are three main research challenges to consider when studying drinking water. Wisconsin's Water Library holds many resources on these topics.

The first challenge is to protect the source of water- either groundwater or surface water- especially as water is becoming a scarce resource in many locations. The second is to harness the flow of water- developing technologies that control runoff. The third is to treat and deliver safe water.
Scientists and researchers have been studying to meet these three challenges for nearly a century. For more information, visit "From Source to Tap" at the US EPA website.
