FORDYCE, Neb. (AP) — A 23-year-old South Dakota woman has been killed in a car collision with a semitrailer in northeast Nebraska.

Cedar County authorities say Stacey Myers, of Yankton, S.D., died early Sunday morning. The crash occurred around 4 a.m. west of Fordyce on U.S. Highway 81, about two miles south of Nebraska Highway 12.

The sheriff’s department says the truck driver wasn’t hurt.

The accident is being investigated.

FREMONT, Neb. (AP) — The American Water Works Association says Fremont has the best-tasting water in the country.

Local Fremont media says the city won the association’s annual Best of the Best Water Taste Test, besting the regional winners from across North America.

The city water comes from nine wells with an average depth of 90 feet in a well field about three miles southeast of the city, near the Platte River.

Officials say the city water treatment plant adds fluoride and a little chlorine and a substance to control manganese.

LINCOLN, Neb. (AP) — Adults taking a GED test in Lincoln, Hastings and Norfolk will soon have the option to answer all of the questions on computers.

Nebraska Department of Education administrators announced that they will offer the new, computer-based tests starting June 25. The remaining 28 Nebraska-based testing centers will allow computerized GED testing no later than January.

Nebraska adult education state director Vicki Bauer says the computerized system expands access to the GED tests and will help more adults find jobs. Bauer says the new system offers better security, more flexible scheduling for test-takers, and instant scores in four out of the five content areas.

The GED test still must be taken in-person at an official testing center. Computerized GED testing will cost $24 for each content area.

HONOLULU (AP) — Civil defense sirens that sounded across Oahu even though there was no emergency were inadvertently activated from Nebraska.

Hawaii Civil Defense spokeswoman Kelly Kunishige (COO’-nee-SHE’-gay) says eight sirens accidentally went off early Thursday because of an engineer doing upgrade work in Nebraska.

Illinois-based Federal Signal has been contracted to do modernization work for Hawaii’s more than 300 sirens across the islands. The state asked the contractor to do some checks, but after doing so, Hawaii’s siren protocols were not removed from the system, allowing some to be activated.

Kunishige says the project will allow sirens to be activated by satellite or cell phone in case radios are down.

The sirens are used during emergencies such as tsunamis.

Tsunami waves struck Hawaii in the aftermath of Japan’s earthquake last year.

LINCOLN, Neb. (AP) — Nebraska authorities say the state’s unemployment rate remained at 3.9 percent in May, still the state’s lowest rate since December 2008.

The May and April rate is slightly lower than the March rate of 4.0 percent. A year ago the Nebraska rate for May was 4.5 percent.

Nebraska’s rate remains the second-lowest in the nation, following only North Dakota’s 3.0 percent.

The national rate rose in May to 8.2 percent from 8.1 percent in April.

LINCOLN, Neb. (AP) — A man with a history of drunken-driving convictions has been given a state liquor license for a Lincoln business.

Local media reports that the Nebraska Liquor Control Commission granted the license on Thursday to Jeremy Schafer for his Top Shelf Beverage Services.

The commission says the license would be revoked if the business or its owners were to have any liquor violation or convictions in the next year.

The 38-year-old Schafer’s most recent DUI conviction was for third offense drunken driving in July 2009.

Schafer says he had abused alcohol to cope with a diagnosis of cancer he’d been given. He told the board he doesn’t drink anymore except to taste wine for his business.

His business partner also has two recent DUI convictions.
