Online portal now available for water quality assessment worldwide

The IIWQ World Water Quality Portal is now available online to “assist with global water quality assessment and capacity building for streams, lakes and rivers.”

This portal was developed by EOMAP GmbH & Co. KG to support the International Initiative on Water Quality (IIWQ) of UNESCO’s International Hydrological Programme. It was launched earlier this week at UNESCO headquarters.

“In view of scarce water quality information at the global and national levels, the portal will be a valuable tool to obtain water quality information, especially in remote areas and in developing country regions such as Africa, Asia, Latin America,” said Dr. Sarantuyaa Zandaryaa, program specialist in the Division of Water Sciences at UNESCO-IHP. “It is also a decision-support tool and will help countries identify the most pressing water quality problems such as pollution hotspots.”

The portal is based on EOMAP’s web service and provides users with near real-time data, campaign planning support, and access to remote and inaccessible areas, according to a press release. Such water quality parameters as turbidity, chlorophyll, and indicators for cyanobacteria blooms can be mapped via satellite globally with weekly or even daily sampling frequencies under cloud-free conditions.

Users can select specific locations to view, such as the Itaipu/Parana reservoir shown above (impounded by Itaipu Dam, which supplies water for a 14,000-MW hydroelectric plant). Or they can set a virtual station on a map of the world. Historical data is available back through 2016.

The data is available through the IIWQ World Water Quality Portal online. EOMAP says environmental managers, politicians and scientists can ingest the service directly through the UNESCO web mapping service into their geospatial information systems for analysis and assessment.
