is a large time commitment. She said it has been a wonderful experience, but a potential new representative would need to be brought up to speed. John Roberts said the UNRBA bylaws do not require anyone to roll off the Board over a period of time, and there is no conflict of interest. He said the decision is up to the BOCC, noting the BOCC appoints a Director and two alternate directors. Commissioner Jacobs asked the term limits of the Chair's office. Pam Hemminger said her officer term is done every January, and her term on the Board is for three years. Chair McKee said Pam Hemminger's offer to train a new appointee is a helpful one. Commissioner Rich asked if this appointment will come up in the near future. Chair McKee said the appointment would come up in December since Pam Hemminger's term ends at the end of November. 4. Orange Well Net (OWN) Update Tom Davis made the following PowerPoint presentation, and reviewed the background information below: Orange Well Net OWN Well Locations and Details (map and graphs) OWN Updates • Brumley Forest Preserve bedrock well • OWN data used to estimate groundwater recharge: • Water Table Fluctuation Method • USGS Groundwater Toolbox also used • Public outreach: • All OWN groundwater level data online • Basic information about water in Orange County - in prep • Means of maximizing well yield - in prep • OWN data and groundwater in Orange County— in prep BACKGROUND: DEAPR's groundwater observation well network, Orange Well Net (OWN), uses a combination of bedrock and regolith wells spread across the main types of bedrock geology present in Orange County. Regolith wells measure groundwater levels in the unconsolidated material present above bedrock to monitor natural stresses on the quantity of groundwater available in storage caused by variations in climatic conditions. Bedrock wells monitor changes in groundwater levels in the bedrock across the County. Groundwater level data collection is underway at seven bedrock wells and five regolith wells. In early 2015, a bedrock well on Triangle Land Conservancy property was added to the network. Attachment A is a listing of well construction details for the current OWN observation wells. Attachment B is a map showing the locations of the wells that are currently in use along with the underlying geology. All data collected by OWN is available to the public on the NC Division of Water Resources (DWR) web site provided below. The web site includes maps of well locations, geologic information, and statistical curves that provide monthly minimum, mean, and maximum groundwater level information for each well in the network. This information can be used to compare recent groundwater levels with historical values.
