Drought conditions increased throughout the United States. DSCI (drought severity and coverage index) increased from 24 to 31, which was the largest DSCI across the country since mid-March. Overall, the percent area of D0 (abnormally dry), D1 (moderate drought), and D2 (severe drought) expanded across the U.S. The area of abnormal dryness and drought increases were most notable in the Ohio Valley, Midwest, and Texas. In addition, D3 (extreme drought) conditions developed in a...

Overall, oceanic and atmospheric conditions were consistent with a weakening El Niño. In the July 2019 Climate Prediction Center update, it was predicted that a transition from El Niño to ENSO (El Niño/Southern Oscillation)-neutral is expected to occur in the next month or two. ENSO-neutral conditions are most likely to remain through the fall and winter in the Northern Hemisphere. To read more, click here .

In high-rate activated sludge (HRAS) systems, extracellular adsorption and intracellular storage have been referred to as the dominant mechanisms for capturing organic carbon from wastewater.

However, the quantification of storage products under short sludge retention time (SRT) of HRAS systems has rarely been studied until now. Since the measurement of storage products is complex and dependent on several variables, alternative solutions for substrate removal through storage are required to understand the high-rate...

According to the United Nations Brundtland Commission Report of 1987, “Sustainable development is…development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”

Its lack of specificity can make...
