Nitrates in Water Linked to Cancer, Iowans at Risk, 5:32

Iowans are at an increased risk of health effects from nitrate exposure. Researchers from the Environmental Working Group and Duke University say as many as 12,000 cancer cases each year nationwide may be linked to nitrates in drinking water. In Iowa, fertilizer and manure runoff are primary contributors to nitrate pollution.

The current federal limit on nitrates in drinking water is 10 parts per million. But recent studies suggest the risk of certain cancers and birth defects increases even at lower levels.

The report said 80% of the nitrate-related cancers were colorectal, with ovarian, thyroid, kidney and bladder cancer accounting for the rest. Treatment costs up to $1.5 billion a year.

The Hard Rock Hotel and Casino is now ready to prepare for betting on college and professional sports.  Today the Iowa Racing and Gaming Commission approved projects requested by the Hard Rock and Grand Falls Casino in Larchwood.

Work will begin Monday on the Hard Rock project that will convert 400 square feet of existing casino space into a sportsbook. 

A groundbreaking ceremony will be held Wednesday to kick off construction of the Siouxland Expo Center, according to the Sioux City Journal.

The ceremony begins at noon. The 100,000-square-foot-venue, which will be built on a parcel of land bounded by Interstate 29 and the Floyd River channel, celebrates the heritage of the city's former stockyards and the continuing success of its ag-based economy. Local leaders have been working for more than a decade to bring an ag-focused expo center to Woodbury County.
