LOVELAND, CO, Sept. 1, 2006 -- In a letter dated July 26, the U.S. Environmental Protection Agency's Engineering and Analytical Support Branch recommended Hach LDO Method 10360 (Luminescence Dissolved Oxygen) for the measurement of DO and the determination of biochemical oxygen demand (BOD) in wastewater, under the National Pollution Discharge Elimination System Program (NPDES).

The Hach LDO method is a breakthrough in the measurement of dissolved oxygen. For many facilities around the world, Hach LDO has become the standard for measuring dissolved oxygen by eliminating the numerous reliability and maintenance concerns inherent in older DO measurement technologies. The LDO® probe has no membranes to clean or replace, no electrolyte solution to replenish, and reduces calibration frequency.

In response to growing customer dissatisfaction with traditional membrane DO technologies, Hach Company was the first to bring its patented LDO technology to market. The Hach LDO technology, first introduced more than three years ago, has been delighting thousands of customers around the globe.

On Jan. 3, the EPA approved ASTM Standard D888-05, which includes the LDO method. The EPA's most recent letter reinforces its recommendation of the Hach LDO method. As a result of the letters issued from the EPA in January and July, many states and EPA regions are authorizing use of the Hach LDO method for BOD analysis and DO effluent monitoring.

The Hach Company (www.hach.com) is based in Loveland, CO, and is a subsidiary of Danaher Corp. The company is a global leader in the development, manufacture, marketing, and support of laboratory, online, and on-site water quality analysis solutions.
