I Springs • i - Spring YSPG6. This spring (also known as~ Armand Spring #1) supplies water to the old Armand homestead. Its EC plot indicates an increasing trend. In September 2001, no sample could be taken since the pipe that carrli es discharge from this spring was clogged. - Spring YSPG10. This spring is actually an artesian well (also known as Armand Artesian Well). It is sampled only when flowing.. No flow at this site had occurred since an attempt to redevelop. this well in July 1996. The leaking casing was repaired on August 9, 1999, and flow has been reestablished.- Zts EC plot indicates a stable trend. comparison of Surface Water Quality to Water Use Standards. ~SCC has compiled a list of surface water standards for agricultural uses (Table 9). This list is composed of CDOH surface water agricultural use standards (CDOH, Reg.31, March 1999). . Table 10 provides a comparison of surface water quality to~agricultural standards. This Paradox database generated table does not include the units of concentration (mg/1 or ug/1) for each parameter. The units used' for each parameter are the same as those listed on the standards table (Table 9) and are also the same as those used in the water quality repoLts. The frequency column on Table 10 indicates the number of exceedences out of the total number of samples (i. e., 1/2 indicates one exceedence out of two samples). Below is a summary of standards that were exceeded. Given in parenthesis is the source and use of each standard. Although the CDOH does not indicate between livestock and irrigation uses in their surface water agricultural standards, they have done 'so in their similar ground water agricultural standards (see Table 5). 'For the sake of discussion, SCC chooses to use those ground water use standards classifications (livestock or irrigation) for surface water; use evaluation. 12
