The <br /> Blackwood Farm observation well experienced a groundwater level decrease of approximately <br /> seven feet from May through November 2011. The groundwater level in the Millhouse Road well <br /> fell nearly five feet during the same time interval. The Rocky Ridge observation well experienced <br /> a decrease of seven feet between May and November 2011. The groundwater level in the Eu- <br /> banks Road well decreased approximately six feet from April through October 2011. The obser- <br /> vation well located in southern Orange County on Ray Road experienced a decrease in ground- <br /> water level of five feet over the 2011 growing season. In fact, the groundwater level in this well <br /> has consistently decreased since May 2010, shortly after data collection began. Finally, the <br /> groundwater level in the Eno Confluence well decreased more than five feet from April through <br /> November 2011. <br /> The collected data also shows that as of April 2012, <br /> groundwater recharge has occurred in most of the u j° <br /> bedrock observation wells such that the groundwater <br /> levels measured in late spring 2012 are similar to <br /> those that were measured in spring 2011. The ex- ' <br /> ception to this is the Ray Road well, as discussed <br /> above. Given the short period of record for the ob- <br /> servation wells to date, it is difficult to derive addition- <br /> al conclusions. <br /> Collins Creek in vicinity of <br /> OWN regolith wells during <br /> dry summer months. <br /> 5 <br />
