Description This groundwater quality monitoring study was designed to determine nitrate trends and to establish the framework for a long-term groundwater monitoring network in the central Sumas-Blaine surficial aquifer in Whatcom County. During 2003-05, groundwater was sampled for nitrate-nitrogen every other month for two years from 35 wells. The results of this study reinforce findings from previous studies: groundwater contains elevated nitrate concentrations, with concentrations as high as 43 mg/l. Additionally, it was determined that there is an increasing nitrate trend at a rate of 0.46 mg/l per year.
