Water Testing For Over 40 Public Water Suppliers Is Under Review By Iowa Department Of Natural Resources

The Iowa Department of Natural Resources is reviewing water testing done for nitrates in 43 public water supplies after discovering some results which didn’t look right. D-N-R environmental specialist, Kathy Lee, says the problem happened with samples tested by Mangold Environmental Testing in Storm Lake.

Lee says they asked Mangold to stop doing samples and have been working with them to try and determine what went wrong.

Lee says the water supplies are periodically tested to be sure the nitrate levels meet acceptable federal standards.

Lee says Mangold has been cooperating with them as they try to figure out the issue. She says the D-N-R does require notification within 15 days when new equipment is placed into service at testing facilities and Mangold didn’t let them know for a couple of months. Lee doesn’t know yet if the company will face a penalty for the late reporting.

The D-N-R and Mangold each sent letters to the operators of the water supplies to notify them of the issue. Local entities impacted include: Breda Water Supply; Dow City Water Works; Early Municipal Water Supply; Grand Junction Municipal Water Department; Lake View Water Supply; Schaller Water Supply; and the West Central Rural Water Association. A listing of the remaining entities can be found below.
