Texas has the dubious distinction of leading the nation in polluted waterways. A new report draws upon self disclosed data by industrial facilities provided to the EPA. The study counted 17 ...
Hinkley groundwater contamination. From 1952 to 1966, Pacific Gas and Electric Company (PG&E) dumped about 370 million gallons (1,400 million litres) of chromium -tainted wastewater into unlined wastewater spreading ponds around the town of Hinkley, California, located in the Mojave Desert about 120 miles north-northeast of Los Angeles.

The anoxygenic phototrophic iron oxidation was the first anaerobic metabolism to be described within the iron anaerobic oxidation metabolism. The photoferrotrophic bacteria use Fe 2+ as electron donor and the energy from light to assimilate CO 2 into biomass through the Calvin Benson-Bassam cycle (or rTCA cycle) in a neutrophilic environment (pH 5.5-7.2), producing Fe 3+ oxides as a waste ...
Rust is an iron oxide, a usually reddish-brown oxide formed by the reaction of iron and oxygen in the catalytic presence of water or air moisture.Rust consists of hydrous iron(III) oxides (Fe 2 O 3 ·nH 2 O) and iron(III) oxide-hydroxide (FeO(OH), Fe(OH) 3), and is typically associated with the corrosion of refined iron.
Water pollution was identified as a growing problem in the US by scientists, government officials and the public in the 19th century. Many cities and towns piped their untreated domestic sewage into nearby waterways. Wastewater discharged by factories, mines and other businesses increased as the economy expanded.
A hack that caused a small Texas town’s water system to overflow in January has been linked to a shadowy Russian hacktivist group, the latest case of a U.S. public utility becoming a target of foreign cyberattacks. The attack was one of three on small towns in the rural Texas Panhandle.
Much agricultural pollution is exacerbated by surface runoff, leading to a number of down stream impacts, including nutrient pollution that causes eutrophication. In addition to causing water erosion and pollution, surface runoff in urban areas is a primary cause of urban flooding , which can result in property damage, damp and mold in ...
During the 1990s, the Texas Legislature moved to make natural-resource protection more efficient by consolidating programs. In 1991, it combined the Texas Water Commission and the Texas Air Control Board to create the first version of the TCEQ, known as the Texas Natural Resource Conservation Commission until fall 1993.
