What’s in it
AI summary Iowa agencies will start separating water quality data to show exactly how much pollution comes from runoff rather than specific pipes. This information will be published on a shared website for the public to see. These reports will no longer be kept secret, even if the data comes from land near farms or livestock operations.1
Read the official explanation
This bill requires the department of natural resources and the division of soil conservation and water quality within the department of agriculture and land stewardship to disaggregate data regarding surface water quality measurements resulting from monitoring, according to designated use segments established by the department. The disaggregated data must include water quality measurements delineating nonpoint source contributions to designated use segments.3). The department and division must publish and update water quality reports specifying the disaggregated data on an internet site administered cooperatively by the two agencies. The bill provides that the data is not subject to confidentiality requirements that otherwise could apply to landowners who operate a crop or livestock operation near a water source.
