Investigators who were closely associated with five groundwater monitoring programs were asked to critically examine their studies as a guide to others involved in similar projects. The particular question to be answered was, "What monitoring techniques should have or could have been implemented?" given that time and money were not constraints. The case studies involved contamination of aquifers from oil field brine disposal, plating waste disposal, landfill leachate, nitrate from multiple sources, and recharge from an oxidation pond. Among the general recommendations of the investigators, resulting from the process of critical evaluation of their associated projects, were the following: establish interdisciplinary committees to set up the monitoring program; maximize the density of well network; use alternative methods to wells; completely analyze the samples, including heavy metals; thoroughly examine the hydrogeology of the problem site; use tracers; develop predictive computer models of the flow system; monitor in the zone of aeration, where applicable; develop innovative methodologies; and continue monitoring until the problem is thoroughly quantified. |
