Description This work was undertaken to assess current groundwater quality conditions and trends for the high-growth communities of Agnew and Carlsborg which lie north and west of the city of Sequim. Eight previously sampled wells were monitored quarterly from December 2000 to September 2002 for field parameters, total persulfate nitrogen, nitrate+nitrite-N, total and fecal coliform bacteria, chloride, total iron, and total manganese. Trend analysis of the nitrate data for each well suggests that, of the eight wells evaluated, three showed a statistically significant increase in nitrate-N concentration, four showed no trend, and one showed a decreasing trend.
