Officials in Ohio are urging residents not to sweep their leaves into the street for collection because they can wash into streams and kill fish. The Ohio Environmental Protection Agency said soluble nutrients such as phosphorus from dried leaves on streets and curb sides can wash into storm drains that discharge directly into nearby waterways and cause algae blooms that are fatal to fish. Property owners should consider raking leaves only to a grassy area along the road where runoff water...
Storm season is just around the corner. If left unchecked, the litter, leaves, and automobile fluids that have collected on the street surfaces of our communities will flow along with rainwater, untreated, into water bodies like the Los Angeles River and the ocean. The County of Los Angeles Department of Public Works (Public Works) urges residents to take a few minutes now to sweep up cigarette butts, leaves, lawn clippings, and trash from the street gutters near their homes. Green waste and...
By Paul Davidson HOLTWOOD, Pa. -- The Holtwood Hydroelectric Dam on the Susquehanna River here hasn't changed much since it cranked up in 1910. Outside, gulls perch on the crest of the dam wall above a picturesque waterfall as a lone boater skims across a serene lake. Inside the long, narrow powerhouse lined with neoclassic arches and peeling green-and-white walls, 10 hulking, steel-encased generators emit a shrill hum. From below comes a steady, subway-train-like rumble -- the...
For the first time, the world's freshwater aquifers will soon be charted on a map, the United Nations announced Wednesday in New York. The United Nations Educational, Scientific and Cultural Organization's map of the world's underground water resources will be submitted to the U.N. General Assembly last week. The UNESCO map will identify 273 aquifers shared by at least two countries, using data compiled since 2000 by its international hydrological program. It will include information about...
By Mark Tallentire A WATER company has defended its environmental record after a conservation group said it was being allowed to dump unregulated sewage in the region's rivers. Northumbrian Water hit back after the Marine Conservation Society (MCS) accused the Environment Agency of giving water companies a "licence to pollute" by allowing thousands of overflow pipes to dump into rivers and coastal waters. The MCS said about 3,500 combined sewer overflows (CSOs), which discharge waste water...
The last thing anyone wants shoved in his mailbox during these tight economic times is another utility bill from the government. So it was a given that an hourlong presentation to Roanoke City Council on how to pay to improve the city's storm sewer system would be met with the level of enthusiasm usually reserved for a root canal. But like decaying teeth, crumbling infrastructure can't be ignored forever. It can be postponed, true, but inevitably one has to face the dentist. Roanoke's...
U.S. scientists say whether another Great Plains 1930s-type "dust bowl" again develops depends on underground water storage depth. Recent modeling results show the depth of the water table, which results from lateral water flow at the surface and subsurface, determines the relative susceptibility of regions to changes in temperature and precipitation. "Groundwater is critical to understand the processes of recharge and drought in a changing climate," said Reed Maxwell, an atmospheric...
By Anonymous Ground was broken on August 22 at Coachella Valley Water District's (CVWD) newest full-scale groundwater recharge facility, which will replenish 40,000 acre-feet annually into the eastern Coachella Valley's aquifer. This amount of water is equal to what is used each year by about 85,000 residents and will alleviate the overdraft of groundwater supplies throughout the eastern valley. Representatives from all levels of government, other water agencies, agriculture and business...
By Juan-Carlos Rodriguez Journal Staff Writer Chava Trucking Co., which was on the receiving end of a nearly $1 million fine by the New Mexico Environment Department in April, has come up with a plan to start cleaning up its mess. The business, located at 6313 Broadway SE, was busted by NMED for what it says was improper management of hundreds of lead-acid batteries, thousands of gallons of used oil and other "unknown wastes" at the site. NMED says the business has had multiple...
By Rebecca Kimitch Efforts to rid San Gabriel Valley water of harmful chemicals and to increase supplies in the face of a statewide drought are likely to get a $10 million boost thanks to legislation signed by the governor. The money is part of an $842 million water package approved by Governor Arnold Schwarzenegger Tuesday. "This is an historic moment, the first time ever any bond money has been allocated to the San Gabriel Valley for groundwater cleanup," said Assemblyman Mike Eng,...
