• rising trends since 1984 through 1989. The conductivity in both' <br />wells seems to be declining overall from 1990 through 1993. <br />The conductivity of water in well J1 (Figure B-36) was steady <br />to 1985, followed by a rising and declining trend. After a steady <br />period in 1990, conductivity values rose in 1991 and became fairly <br />steady in 1992 and 1993. Conductivity in the COY alluvial well <br />(Figure B-35) gradually increased from 1985 to 1990. Conductivity <br />values hit a high of 2650 µmhos/cm in 1990 and then declined in <br />1991 through 1993. <br />Water collected from the 3rd White Sandstone well 81-03a <br />yielded the conductivities plotted on Figure B-37. Conductivities <br />in well 81-03a had been steadily increasing since 1987 but were <br />• fairly stable since 1989 and may be starting a declining trend. <br />Values of conductivity collected to date for well GLUX-1 are <br />presented on Figure B-38 and have been fairly stable. The 1992- <br />1993 data may be indicating the start of a declining trend, <br />Conductivity data for well GMP-1 have been collected for the past <br />three years and are presented in Figure B-39. The first value in <br />late 1990 was high, but the values observed for 1991 and 1992 are <br />lower and have remained fairly stable. <br />3.2 TDS <br />TDS is the measurement of the total dissolved minerals in <br />water. It typically correlates well with constituents which make <br />up the majority of the dissolved solids and therefore, is a good <br />. indicator of trends for these constituents. Conductivity is <br />3-7 <br />
