Ground-water quality and levels, and surface-water, meteorological and other environmental data collected at two storm-water retention basins near DuPont, Washington, Water Years 1998-2000

Hydrologic, meteorological, and other environmental data were collected at two storm-water retention basins near DuPont, Washington, during water years 1998-2000. Soils of one of the basins were treated with a mixture of gypsum, grass seeds, and mulch. Data for ground-water quality and groundwater levels were collected from six wells that were installed in and near the basins. The water level of an intermittent pond in the gypsum-treated basin was monitored, as were incoming solar and net radiation, air temperature and water-vapor-pressure deficit, wind speed, precipitation, temperature of water in the pond, and energy flux into the floor of the basin. This report presents the data so they will be available for future investigations of hydrologic effects of highway stormwater retention systems.
