Between October 2007 and August 2009, groundwater levels remained below this threshold, and high concentrations of chloride and sodium occurred in two of the sentry wells late in 2009
This indicates a lag in time between lower water levels and significant increases in sodium and chloride, indicators of seawater intrusion.
