Nitrate concentration exceeded the drinking water standard for this constituent in well 4, <br /> the background well,but not in the two wells sampled in the wastewater disposal area. <br /> The elevated level of this constituent in the background well is presumably a regional <br /> characteristic. The apparent decline of nitrate level in the disposal area may be an <br /> indicator that some reducing agents are reaching the water table here. Nevertheless, <br /> nitrate is still abundant even where wastewater is being applied. Nitrate ion is always <br /> absent in reducing environments because it is a readily used electron acceptor. <br /> Therefore, reducing conditions typical of organic wastewater do not reach down to the <br /> level of the groundwater. <br /> Please call at (831) 426-9054 with any questions you may have concerning groundwater <br /> monitoring and reporting at this site. <br /> Sincerely yours, <br /> Richard Armstrong, Ph.D., P.E. <br /> Principal Scientist <br /> Cc: Vince Westphal, Bear Creek Winery, 11900 N.
