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.

Iowa Senate Bill 2266, introduced on February 10, 2026, aims to enhance clean water monitoring by mandating that state agencies publish detailed, disaggregated data on water quality. This includes specific information on pollution contributions from nonpoint sources, such as agricultural runoff and urban stormwater. The bill is currently under review by the Senate Natural Resources and Environment Committee.

Supporters of SF2266 argue that the bill promotes transparency and accountability in environmental monitoring. By requiring detailed reporting on pollution sources, the legislation is seen as a step toward more effective water quality management and protection of public health.

Critics of the bill express concerns about the potential administrative burden on state agencies and the agricultural sector. They worry that the requirement to publish disaggregated data could lead to increased regulatory scrutiny and compliance costs, particularly for farmers and other stakeholders involved in nonpoint source activities.
