A systematic investigation of tritium activity in precipitation, surface water, springs, and groundwater of the Roswell artesian groundwater basin in New Mexico has been supplemented by stable isotope determinations (oxygen-18 and deuterium). Two recharge contributions to the Principal Aquifer (the San Andres Formation) have been recognized. A fast recharge component, of relatively high tritium activity, consists of snowmelt and storm runoff and enters the groundwater system as leakage from surface drainages where these cross the karstic San Andres Formation. A slow recharge component is transmitted from the western mountains along the Glorieta-Yeso contact below the San Andres and leaks upward. -from Authors
