k4 KLEINFELDER <br /> • We recommend that each of the eight monitoring wells be re-sampled, to confirm the <br /> initial groundwater sample analytical results, and the samples be analyzed for at least <br /> the following: <br /> • Nitrate as NO3 <br /> • Total and fecal coliform bacteria <br /> • Organic analyses by EPA Methods 507 (Atrazine) and 632 (Diuron) <br /> Before collecting the groundwater samples for the coliform bacteria analysis, we <br /> recommend that each of the wells be disinfected as a quality control measure to reduce <br /> the potential for inadvertent contamination. Also prior to sampling, the wells should be <br /> purged and allowed to stand for a designated time to remove the residual chlorine within <br /> the well casing and well bore annulus space within the saturated zone. <br /> This report is subject to the "Limitations" presented in Chapter 6.
