The Quality of Surface Waters in Texas

Description: Abstract: The discharge-weighted average concentrations of dissolved solids, chloride, and sulfate for many of the principal streams in Texas are less than 500 mg/1 (milligrams per liter), 250 mg/1, and·250 mg/1, respectively. At 65 of 131 sites on streams that were sampled at least 10 times, the biochemical oxygen demand of at· least half the samples exceeded 3,0 mg/1. At 20 of the sites, the dissolved-oxygen content of at least !half the samples was less than 5.0_ mg/1. The higher concentrati… more

Land-Surface Subsidence in the Area of Burnett, Scott, and Crystal Bays Near Baytown, Texas

Withdrawals of water from industrial wells and declines in artesian pressures began about 1918. As much as 280 feet (85.3 meters) of artesian-head decline has occurred in the Evangeline aquifer, and as much as 320 feet (97.5 meters) of decline has occurred in the Alta Lorna Sand. Subsidence of the land surface began about 1920, and as much as 8.2 feet (2.5 meters) of su… more
