Note: The U.S. Geological Survey (USGS) reports these data, which were collected by various groups for World Water Monitoring Day 2007 in Virginia. The Water Environment Federation (WEF), in coordinating World Water Monitoring Day, receives the data from those who collected it. After processing the data, WEF provides the data to the USGS for posting on this web page. When such water-quality data are collected, reported, and processed, errors can be introduced such that reported values do not represent the quality of the water at the time the water was collected. Because the data reported for World Water Monitoring Day 2006 in Virginia are not collected by the USGS, the data have not been verified or evaluated by USGS quality assurance procedures. Thus, individual users are responsible for determining if any reported values might be incorrect. A brief discussion provides general guidelines to assist users who might not be fully knowledgeable of water quality in this determination.
