Basements that flooded after heavy rains deluged the Colorado Front Range in September 2013 had higher levels of airborne mold and other fungi months after the waters receded compared with basements that didn’t flood, according to a study by the University of Colorado Boulder.

Nine states report record low snowpacks. A report from the US Department of Agriculture states, “the largest snowpack deficits are in record territory for many basins,especially in the Cascades and Sierra Nevada where single – digit percent of normal conditions prevail. Very low snowpacks are reported in most of Washington, all of Oregon, Nevada, California, parts of Arizona, much of Idaho, parts of New Mexico, three basins in Wyoming, one basin in Montana, and most of Utah.” This region is undergoing the warmest winter temperatures since record keeping began in 1895.

Emergency hospital admissions rise following heavy rainfall after a new study found consumers’ drinking water can be contaminated by the release of untreated wastewater, increasing the risk for gastrointestinal illness.

"Combined" sewer systems collect both sewage and stormwater runoff on the way to treatment facilities. When heavy rainfall fills these systems beyond their capacity, untreated wastewater can back up into homes. 

To reduce the risk of home flooding during heavy precipitation, municipalities often discharge some of the untreated flow into nearby bodies of water. 

La cartera energética EE.UU. cambia con el tiempo. Los avances científicos y tecnológicos relacionados con el fracking hidráulico han aumentado drásticamente el suministro de petróleo de Estados Unidos y el gas; debido a esto, una economía basada en metano, en la que el gas natural ofrece la mayor cuota de consumo de energía primaria, es ahora un posible escenario para el desarrollo energético de Estados Unidos. En un informe publicado por el Instituto Americano de Geociencias (AGI), los componentes sociales, políticos, técnicos y ambientales de una economía de metano son identificados. El informe también menciona cómo la industria, el gobierno y el público podrían trabajar mejor juntos para promover los objetivos energéticos comunes.

Strange as it sounds, flood control can be part of the solution to managing California’s droughts. University of California scientists have shown that making more room for floodwaters can improve the state’s groundwater supplies and fisheries.

Removing some levees or rebuilding aging ones some distance away from riverbanks can appreciably replenish aquifers during wet years, providing some relief during droughts.
