' Each spring monitoring station is scheduled for dischazge and water quality measurements three
(seasonal sampling window) times a yeaz. Field meazurements included flow, pH, conduttiviry,
temperature, dissolved oxygen, and turbidity. laborarory analyses included pH, specific conductance,
to[ dissolved solids, total suspended solids, iron (total) and manganese (total). the springs
azsociated with the Jumbo Mountain tract (7-26B and CR-12) wer a sampled monthly. In addition to
these parameters measured for other springs, laboratory analysis included measurements of alkalinity
(az CaCO~ btrarbotlate (az CaCO~, calnum (dissolved), carbonate (az CaCO~, chloride, magoeslum
