temperature at AMW-5R is not observed when the data are limited to the period of May 2000 to • <br />August 2012, indicating that values have stabilized in the past twelve years. <br />The third quarter 2012 concentration of TDS at AMW-5R (850 mg/L) is within the range of <br />concentrations observed at that well since March 1994 (213 to 880 mg/L), but is above the <br />National Secondary Drinking Water Standard of 500 mg/L. However, the increasing trend for <br />TDS at AMW-5R is not observed when the data are limited to the period of July 2001 to August <br />2012, indicating that concentrations for this constituent have stabilized in the past eleven years. <br />The third quarter 2012 field turbidity value at AMW-5R (522 NTUs) is consistent with the range <br />of values observed at that well since May 1995 (<0.01 to >1000 NTUs. The increasing trend for <br />field turbidity at AMW-5R is not observed when the data are limited to the period of November <br />2005 to August 2012, indicating that values have stabilized in the past seven years.
