July 24, 2026
This Jupyter notebook connects to the Water Quality Portal (WQP) to query the EPA and USGS Water Quality Exchange (WQX) database. It automates the extraction of water chemistry and ecological indicators—such as dissolved oxygen, salinity, pH, nitrates, heavy metals, and bacterial levels—for local monitoring sites.
Intended Audience & Use Case: Tailored for biology, chemistry, and environmental science educators and curriculum designers. The notebook simplifies the retrieval of complex federal water testing histories, allowing teachers to construct lessons comparing water health indicators across different regions or agricultural and urban watersheds.
