Status of Water Levels and Selected Water-Quality Conditions in the Sparta-Memphis Aquifer in Arkansas, Spring-Summer 2003

During the spring of 2003, water levels were measured in
341 wells in the Sparta-Memphis aquifer in Arkansas. Waterquality
samples were collected for temperature and specificconductance
measurements during the spring-summer of 2003
from 70 wells in Arkansas in the Sparta-Memphis aquifer. Maps
of areal distribution of potentiometric surface, change in waterlevel
measurements from 1999 to 2003, and specific-conductance
data reveal spatial trends across the study area. The highest
water-level altitude measured in Arkansas was 328 feet
above National Geodetic Vertical Datum of 1929 (NGVD of
1929) in Craighead County; the lowest water-level altitude was
199 feet below NGVD of 1929 in Union County.
