AKRON, Ohio (AP) - Millions of gallons of drilling waste have been injected underground in Ohio, leading some to worry about possible ties to earthquakes.

The drilling practice known as hydraulic fracturing uses chemically-laced water to free oil and gas from underground shale formations. Ohio has 181 wells to inject waste fluid underground.

The Akron Beacon Journal reports that nearly 50 percent of the drilling waste comes from Pennsylvania, which last year banned shipment of the liquid to state water treatment plants.

Experts suspect that the drilling fluid can trigger earthquakes along geological fault lines by allowing rocks to flow more easily past one another.

COLUMBUS, Ohio (AP) - A toxic algae treatment in Ohio's largest inland lake over the summer was successful, the state's Environmental Protection Agency director says.

The agency has released a report that says the 3.3 million gallons of the chemical alum dropped into Grand Lake St. Marys was more successful than anticipated, killing 56 percent of phosphorous in the treated area.

Phosphorous feeds the blue-green toxic algae, which produces a nerve toxin that can sicken humans and kill pets and animals.

Ohio EPA Director Scott Nally calls the results "absolutely exciting," saying the lake was able to stay open all summer because of the treatment.

EMPORIA, Kan. (AP) - Tyson Fresh Meats Inc. is recalling about 131,300 pounds of ground beef that might be contaminated with E. coli.

The U.S. Department of Agriculture announced Wednesday that it became aware of the problem when Ohio health authorities reported that a family in Butler County had become ill with E. coli. Ground beef in the family's home tested positive for the bacteria.

The products being recalled include Kroger-brand ground beef; Butcher's Brand beef and generic label beef, which were all produced Aug. 23.

Poor Will’s Almanack for the Third Week of Early Fall.

Wind comes in ahead of the first October cold, pulling off foliage from box elders and sycamores, red Virginia creepers, and elms, blowing hickory leaves into the rivers. Early in the morning, Orion lies in the middle of the southern sky. The locust trees and cottonwoods, the grape vines and the milkweed leaves are gold. Black walnut trees are bare.

Japanese beetles are almost gone now. Chiggers have disappeared from the garden. Taking their place, cucumber beetles hide in the roses. The mornings bring occasional robins passing through, and once in a while a cardinal will call.

PARKERSBURG, W.Va. (AP) - A science panel studying the possible health effects of a chemical known as C8 plans to release its findings by July 2012.

Media outlets report that the three-member C8 Science Panel discussed its studies of the chemical, also called perfluorooctanoic acid, during a public meeting Monday evening in Parkersburg.

Panel member David Savitz told the crowd of about 50 that the scientists recognize the financial and emotional stakes and public health consequences.

The panel was named in 2005 as part of a lawsuit filed by Mid-Ohio Valley residents against DuPont that claimed C8 contaminated water supplies in Ohio and West Virginia. DuPont uses C8 at its Washington Works plant near Parkersburg.
