A bill for an act relating to clean water monitoring by requiring agencies to publish disaggregated data, including data associated with contributions by nonpoint sources.

SF 2266 requires Iowa's Department of Natural Resources and the Division of Soil Conservation and Water Quality to publish disaggregated water quality data online, specifically showing contributions from nonpoint sources like agricultural runoff to designated water bodies. This affects agricultural landowners and operators near water sources, as the bill removes confidentiality protections for data identifying their operations that contribute to water quality issues. The key mechanism mandates agencies to break down aggregated monitoring data into detailed reports by water classification, updating these publicly on a shared website. This change makes previously confidential data about farm-related water pollution contributions publicly accessible.
