-
(Great Plain Agricultural Council, 2003)Groundwater lies hidden beneath the soil, out of sight and largely out of mind. As a result, it’s poorly understood by most who depend on it for drinking water and other uses. Misconceptions about groundwater are common. ...
-
(Texas Water Resources Institute, 2013)Nitrogen in groundwater, more specifically nitrate, is common in certain areas and is often associated with agricultural production or urban areas underlain by coarse soils. While the presence of nitrates in groundwater ...
