Can We Have Our Water and Drink It, Too? Exploring the Water Quality-Quantity Nexus
Water quantity and quality have generally been considered as separate problems and have usually been treated as such in policy-making and environmental restoration efforts. Increasingly, however, research and experience is beginning to show a strong link between water quantity and quality.

What the map doesn’t show is topography. Pink granite can be very resistant, meaning it…

Geology with a Taste of Safari
