Analytical results from well water samples were used <br /> to assess changes in shallow groundwater chemical composition. During Second <br /> Quarter 2010, prior to the sampling event no recycled water was discharged to the <br /> Land Application Sites.3 <br /> 3 Doug Little, Veolia Water West Operating Services, written communication, June 28, 2010. <br /> - 9 - <br />
