INFORMATION ITEM <br />~l <br />~~;. ,.ti. <br />+~, ~~ <br />I~~~artx~~~.~ ~~" ~~~~~: ~~,~~nt, <br />MEMORANDUM <br />TO: David Stancil, DEAPR Director <br />FROM: Thomas W. Davis, Water Resources- Coordinator <br />DATE: June 1, 2011 <br />RE: 2011 Annual Observation Well Network Report <br />Enclosed is the first annual report of the Orange County Groundwater Observation <br />WeII Network, known as Orange Well Net. This report documents the progress <br />which has been made toward the goal of having a groundwater observation well <br />network in Orange County dedicated to monitoring local groundwater conditions. <br />The network is designed to provide important long-term information regarding the <br />quantity of groundwater available to the citizens of the County, especially during <br />times of drought. <br />The report discusses how arrangements have been made to utilize existing out-of- <br />service water supply wells for the long-term collection of groundwater level <br />information. The report includes hydrographs covering the twelve month period <br />since the initiation of data collection in March 2010 for each of the six bedrock wells <br />currently utilized in Orange Well Net. This report also discusses expansion of the <br />existing well network through the utilization of new regolith wells that are being <br />installed by state and federal natural resource agencies as part of a cooperative <br />investigation in southern Orange County. It is anticipated that this effort will also <br />yield important local information, especially in future years as trend analysis <br />becomes more enabled. <br />Finally, staff is working to determine groundwater ua/it in each of the observation <br />wells in Orange Well Net and should have the results of this analysis soon. There <br />may also be additional means of expanding the well network to enhance the data <br />collection that is currently underway. <br />Additional information about the Orange Well Net is available at the H2Orange web <br />site: http://www.co.orange.nc.us/ercd/h2orange/wellobservation asp <br />Attachment: 2011 Orange Well Net Annual Report <br />Orange County Department of Environment, Agriculture, Parks & Recreation <br />PO Box 8181, Hillsborough, NC 27278 <br />Phone: (919) 245-2510 Fax: (919) 644-3351 <br />
