  • How vulnerable is our groundwater?

    When water travels through soil and bedrock to the water table, it carries minerals, nutrients or chemicals from the surface with it. Environmental research is increasingly concerned with preferential flow, or the movement of water through pores and cracks at a faster rate and bypassing most of the surrounding material, either soil or fractured rock. A special section on preferential flow ...

  • Pesticide pollution slow to reach groundwater

    Underground water aquifers are a significant source of drinking water. In a recent study, French researchers found that pesticides applied to crops can take many years to sink down through the ground and reach groundwater. This means that they may still be entering aquifers, even after agricultural application has stopped. Groundwater is found underground in absorbent layers of rock. ...
