Exploratory well drilling on Long Island to study the effective management of Long Island’s groundwater resources
The drilling will better define the aquifer system, track saltwater encroachment, and inform a new groundwater-flow model for the Island. Knowledge of the...
A decade of drought in California has eased after the first month of 2017 thanks to heavy rains and snow, a fact that Landsat images are helping to confirm.
