Education and Outreach - World Water Monitoring Day

The water quality requirements administered by the Commission were originally in the Tri-State Compact. The Commission’s water quality regulations were adopted in 1971with revisions in 1977 and further amendments in 1984, 1986 and 1997. Water quality regulations, as amended through October 1997, include general and specific requirements and apply to all waters within the Interstate Environmental District.

There are two classes of waters within the Interstate Environmental District: Class A and Class B. Class B is further divided into two subclasses, B-1and B-2. It is the underlying principle of these regulations that each class and subclass is to be suitable for its best intended uses and that all waters are to be protected, maintained, and improved to the end that they will afford as satisfactory conditions as possible for the maintenance and restoration of the natural ecosystems. All waters should be aesthetic assets and should, at a minimum, be available for those recreational uses which do not bring the human body into direct contact with the water.

WWMD 2009 
  Founded by the America’s Clean Water Foundation in 2002 with a national focus, World Water Monitoring Day is an international education and outreach program that builds public awareness and involvement in protecting water resources by engaging citizens to conduct basic monitoring of their local water bodies. The first National Water Monitoring Day in the United States was a great success. On July 28, 2006, the Water Environment Federation announced its adoption of World Water Monitoring Day (WWMD).

To continue to promote water quality awareness around the globe, sampling activities take place annually on September 18th to commemorate the anniversary of the enactment of the federal Clean Water Act; however, the monitoring window was extended for the first time in 2009 from March 22 (World Water Day) until December 31. IEC has participated in this monitoring effort since its inception.

 The IEC joins thousands of volunteers to sample water quality and report their results. It is estimated that nearly 10,000 sites in 48 states and 80 nations are part of the sampling network. While comprehensive monitoring goes on throughout the year, IEC conducts in situ testing of water quality at nine sites in the upper East River and western Long Island Sound, covering a distance of about 29 nautical miles. These are the same sites monitored by IEC since 2002. The ambient water quality stations represent a subset of the LISS sampling network. In addition to recordings of meteorological and tidal conditions, parameters measured include dissolved oxygen, salinity, temperature, and water clarity. All IEC data has been submitted to the World Water Monitoring Day website,, for inclusion into an international data bank. 



While World Water Monitoring Day might be associated with fresh water, it is important to consider the importance and impacts of fresh water quality to marine habitats.  In order to emphasize this point, WWMD has partnered with the 2008 International Year of the Reef.  To achieve increased awareness about the value and importance of coral reefs, people world-wide should explore means for protecting these endangered aquatic ecosystems
