Editing Wastewater nutrient overflow load (section)

== Observational Status ==
Current monitoring of wastewater nutrient overflow loads relies on effluent monitoring programs, water-quality sampling, and reporting mechanisms that vary by jurisdiction and infrastructure. Data availability and quality can be uneven, with some regions having detailed records and others limited by resource constraints. Ongoing efforts by agencies such as the U.S. Geological Survey and the [https://en.wikipedia.org/wiki/United_States_Environmental_Protection_Agency Environmental Protection Agency] aim to improve data collection and estimation methods. Future SIGNAL releases may incorporate enhanced datasets, improved spatial and temporal resolution, and integration with related environmental signals to better characterize nutrient overflow impacts.
