User’s manual for the National Water Information System of the U.S. Geological Survey: Water-Quality System
This user documentation is designed to be a reference for the quality of water (QW) programs within the National Water Information System (NWIS). If you are a new user, the “Introduction” and “Getting Started” sections may be the right place for you to start. If you are an experienced user, you may want to go straight to the details provided in the “Program” section (section 3). Code lists and som

Water-quality and ancillary data collected from the Arroyo Colorado near Rio Hondo, Texas, 2006
The Arroyo Colorado is in the lower Rio Grande Valley of southern Texas and extends from near Mission, Texas, eastward to the Laguna Madre estuarine and coastal marine system, which separates Padre Island from the Texas mainland. Streamflow in the Arroyo Colorado primarily is sustained by effluent from municipal wastewater-treatment plants along the stream banks. Since 1986, the tidal segment of t

Occurrence of selected volatile organic compounds and soluble pesticides in Texas public water-supply source waters, 1999-2001
During 1999–2001, the U.S. Geological Survey, in cooperation with the Texas Natural Resource Conservation Commission, collected samples of untreated water from 48 public water-supply reservoirs and 174 public water-supply wells. The samples were analyzed for volatile organic compounds (VOCs) and soluble pesticides; in addition, well samples were analyzed for nitrite plus nitrate and tritium. This

Volatile organic compound and pesticide data in public water-supply reservoirs and wells, Texas, 1999-2001
To provide data for the Texas Source-Water Assessment and Protection Program, the U.S. Geological Survey conducted a synoptic survey of 48 public water-supply reservoirs and 174 public water-supply wells during 1999–2001. The surface-water samples were analyzed for volatile organic compounds and soluble pesticides. The ground-water samples were analyzed for volatile organic compounds and soluble p
