i A more recent cooperative arrangement allowed Orange County to begin utilizing three new regolith wells installed in 2011 for the collection of groundwater level data from the shallow aq- uifer. Data collection began from three regolith wells in southern Orange County in June 2011. Table 1 lists the well construction details for all of the wells included in Orange Well Net. Figure 1 illustrates the locations of the wells. Figure 2 illustrates the locations of the wells in relation to the generalized bedrock geology of Orange County. This map is based on the recent work of the North Carolina Geological Survey, which updated the knowledge of bedrock geology in the county. Staff downloads groundwater level data periodically from each of the observation wells in Orange Well Net. The collected data is formatted and then uploaded to the North Carolina Department of Environment and Natural Resources (NCDENR) Division of Water Resources (DWR) groundwater level database web site: http://www.ncwater.org/Data and Modeling/Ground Water Data bases/leveltable.ph p? tl=1&net=orange&inactive= This web site is available to the general public and includes significant information regarding groundwater level conditions across North Carolina, including the information collected from Orange Well Net. Unfortunately, the use of the Rocky Ridge bedrock well was terminated in April 2012. All equip- ment was removed from this well and no further data will be collected from this location.
