HOW TO ASSESS GLOBAL WATER QUALITY?

• There are two approaches
• Establish monitoring laboratories and staff
  worldwide to operate a global programme this
  would be exorbitantly expensive and impossible at
  the present time.
• Create a network of participating countries that
  provide data to a central global database.

GEMS/Water Data Collection

• Voluntary from national WQ programmes but also
  universities and other organizations
  non-aggregated.
• Living database.
• Do not control type of data, analytical methods,
  frequency of analysis or submission to
  GEMS/Water.
• Have three classes of stations trend, impact and
  flux.
• Historically data has been very classical but
  moving to collect newer data including
  biological data.

Database Access Data Distribution
New online water quality database GEMStat
launched on March 22nd, World Water Day

• www.gemstat.org -- searchable
• Station(s) selection
• Time period
• Parameter(s) selection
• Statistical Analysis
• promote access to information worldwide
• promote interoperability and comparability of
  datasets
• as up-to-date and comprehensive as possible
