MISSOURI DOCUMENTATION 
Last Edit date: December 9, 2005

      The Missouri Department of Natural Resources (DNR) is the source for most of the water use data collected for Missouri for the 2000 compilation.  Typically the DNR sends questionnaires to major users  those facilities with the capability to pump or divert at least 100,000 gallons per day. For the public supply category, the Division of Environmental Quality (DEQ) provides information gathered as part of the Public Drinking Water Program and the Water Pollution Control Program. The data from these two programs was also the source of industrial water use values.  The Missouri Agricultural Statistical Service (MASS) and a Missouri University Agricultural Extension Irrigation Specialist helped in the estimation of irrigation water use.
      
      Total alluvial aquifer withdrawals in Missouri for 2000 were 176 Mgal/d. The majority of the withdrawals were for public supply (106 Mgal/d) followed by irrigation (59 Mgal/d) and finally industrial (11.1 Mgal/d).  Alluvial aquifer withdrawals accounted for only 10 percent of total withdrawals from all aquifers in Missouri. Over 77 percent of total aquifer withdrawals occur in a south-east part of the state known as the boot heel where a principal aquifer, the Mississippi River Valley alluvial aquifer, is a major source of ground water. 
      
      In Missouri, a line delineating the southern extent of Quaternary continental glaciation divides the state roughly along the Missouri River. Although coarse-grained glacial deposits exist in the glaciated part of the state, for 2000 water use was not assigned to the glacial sand and gravel aquifer unit. All withdrawals from unconsolidated fluvial sediments were assigned to either the Mississippi River Valley alluvial aquifer or alluvial aquifers.  No ground-water withdrawals were assigned to the Other aquifer category for the 2000 compilation.   
      
      Fifty-five out of 115 counties in Missouri had ground water withdrawals from wells screened in alluvial deposits. In general, the 55 counties are located in the northern half of the state. Withdrawals from the 39 counties that are coincident with the area of Quaternary glaciation are not dissected into stream valley withdrawals, and are reported as a whole in the table (122 Mgal/d).
      
      Ground water withdrawals for the 2000 compilation were assigned to a specific aquifer unit based on county data. Sixteen counties with potential stream-valley aquifer withdrawals are located along or south of the line of continental glaciation. These counties are Boone, Callaway, Cole, Cooper, Franklin, Gasconade, Henry, Jackson, Jefferson, Johnson, Moniteau, Osage, Perry, Pettis, St. Genevieve, and St. Clair. The Missouri water use specialist (Rich Huizinga, written communication, April 1, 2005) has been able to identify stream-valley aquifer withdrawals from these counties based on the knowledge gained from site-specific studies.
      
      Thirty-one percent of the total withdrawals from alluvial aquifers (54.4 Mgal/d) occur in stream-valley aquifer units.   These units include: Near St. Louis Upper Mississippi stream-valley aquifer, Missouri stream-valley aquifer, Osage stream-valley aquifer, and the South Grand stream-valley aquifer.  The greatest withdrawals are from the Missouri SVA (50.1 Mgal/d) followed by the Near St. Louis Upper Missouri (3.53 Mgal/d); with minor withdrawals occurring from the South Grand and the Osage SVAs (both 0.40 Mgal/d). The counties with the minor withdrawals, Henry and St. Clair, are not shown as having stream-valley aquifer deposits in the Ground Water Atlas of the United States. Although they do provide some water, small stream-valley aquifer deposits are not shown in the Ground Water Atlas.
