Ambient Water Monitoring Strategy for Iowa: 2016-2021, November 30, 2016

The Iowa Department of Natural Resources (DNR) Ambient Water Monitoring Program provides consistent, unbiased information about the condition of Iowa’s water resources to support decisions affecting the development, management and protection of these resources. To strengthen its services, the program worked with a variety of stakeholders and other DNR programs to develop a five-year strategy for Iowa’s ambient water monitoring efforts. The strategy identifies opportunities to improve the program’s effectiveness in several categories: monitoring objectives, sampling design, data management, products and services, and program evaluation and coordination. Iowa DNR managers and technical staff will use the new strategy to guide decisions affecting the ambient monitoring program over the next five years. The strategy should also serve as a robust informational resource for stakeholders, policy makers, legislators and the public.

FY2015 Ambient Groundwater Quality Monitoring Summary, September 3, 2015

This report summarizes the results of groundwater monitoring that took place from October 2014 - April 2015. Raw, untreated groundwater was sampled from forty-five municipal wells generall characterized as vulnerable to contamination from surface activities. Samples were analyzed for basic water quality parameters, nutrients, atrazine and two of its breakdown products, chloroacetanilide herbicides and their ethanesulfonic and oxanalic acid degradates, and a suite of sixteen pharmaceutical compounds.

IDNR Ambient Groundwater Quality Monitoring: Summary for Fiscal Year 2016, August 31, 2016

This report summarizes the results of groundwater quality monitoring conducted at 68 public water supply wells in Iowa between October 2015 and March 2016. Raw groundwater samples were analyzed for basic water quality parameters, nutrients, atrazine and its degradates, and chloroacetanilide herbicides and their ethanesulfonic and oxanilic acid degradates. In addition, a subset of samples were analyzed for radionuclides including gross alpha and gross beta radioactivity, radium-226, and radium-228.
