Pollution
This covers one of the three planetary crises: pollution
Aquasat: Advancing Remote Sensing of Inland Water Quality
Increasing accessibility to satellite-based water quality estimates so researchers can create better models and facilitate new data-driven approaches to monitoring and understanding critical water resources.
Beach Water Quality Monitoring
The Coastal Resources Division administers beach water quality monitoring, public notification and data reporting to the Environmental Protection Agency and other water quality agencies.

How we measure water quality
Across the state, Environment Protection Authority Victoria’s (EPA) authorised officers and environmental scientists collect water samples to detect pollution and monitor the health of Victoria’s waterways.
Introduction to Marine and Coastal Water Quality Management
This course aims to empower participants with a comprehensive understanding of water quality, with a focus on its importance in the Caribbean region.
Land Use and Land Cover Shape River Water Quality at a Continental Caribbean Land-Ocean Interface
This study shows that river water quality feeding a seasonally hypoxic tropical bay in Panama varies sharply with catchment land use and land cover, with pristine peat swamps producing naturally low-oxygen blackwater and more urbanized or deforested catchments showing elevated nutrients, highlighting how even moderate land-use changes can alter coastal ecosystem inputs.
Multivariate Statistical Analysis for Water Quality Assessment: A Review of Research Published between 2001 and 2020
This review analyzes two decades of water-quality research using multivariate statistical analysis, showing rapid growth—especially in developing countries—and identifying PCA, HCA, FA, and DA as the most widely applied techniques across studies of rivers, groundwater, and lakes.
National Centers for Environmental Information
NCEI provides access to an extensive archive of environmental data through several platforms. We deliver the climate, coastal, oceanographic, and geophysical data you need in a variety of formats.
Pollution in the Murchison Bay, Lake Victoria
Lake Victoria, Africa’s largest freshwater lake, is undergoing severe ecological decline driven by pollution and eutrophication that threaten its unique biodiversity and the well-being of surrounding communities, even though improved operation of existing treatment facilities could significantly reduce organic pollution on the Kenyan side.
Recent Advances in Remote Sensing and Artificial Intelligence for River Water Quality Forecasting: A Review
A review of emerging methods showing how real-time monitoring, remote sensing, and advanced machine learning models are transforming the accuracy and efficiency of inland river water-quality forecasting and management, especially LSTMs, GRUs, and hybrid approaches.
Regional Environmental Monitoring Platform
A map view showing geospatial context to provide an easy and shareable snapshot of environmental/spatial data for reporting or display.
Statistical Methods in Water Resources
This text began as a collection of class notes for a course on applied statistical methods for hydrologists taught at the U.S. Geological Survey (USGS) National Training Center. Course material was formalized and organized into a textbook, first published in 1992 by Elsevier as part of their Studies in Environmental Science series. In 2002, the work was made available online as a USGS report.
Statistical tools for water quality assessment and monitoring in river ecosystems – a scoping review and recommendations for data analysis
This review highlights the limitations of widely used OLS methods in water-quality research and provides practical guidance on modern statistical approaches, such as GLS, mixed-effects models, and Bayesian analyses, that better handle the temporal, spatial, and unbalanced nature of environmental datasets.
Surface water quality profiling using the water quality index, pollution index and statistical methods: A critical review
This systematic review synthesises decades of research on surface water quality profiling, outlining major pollution sources, widely used Water Quality and Pollution Index models, key parameters, and emerging needs for more technology-driven approaches to improve monitoring and assessment.
UNEP GEMS Water Data Portal
The Global Freshwater Quality Database GEMStat provides scientifically-sound data and information on the state and trend of global inland water quality. As operational part of the GEMS/Water Programme of the United Nations Environment Programme (UNEP), GEMStat is hosted by the GEMS/Water Data Centre (GWDC) within the International Centre for Water Resources and Global Change (ICWRGC) in Koblenz, Germany.
