Distribution and mass of nitrate in the unconfined aquifer beneath the intensively cultivated area north of the Rio Grande, San Luis Valley, Colorado, 1997 through 2001

Stogner, Robert W., Sr.

Abstract:

Current (1997?2001) and historical (1948?49, 1968?69) nitrate-concentration and water-level data collected from wells completed in the unconfined aquifer in the intensively cultivated area north of the Rio Grande in south-central Colorado were used to determine the distribution and mass of nitrate and to determine short- and long-term trends in the concentration and mass of nitrate in the unconfined aquifer.
