that the monitoring of the Park be integrated with the other existing monitoring efforts 40 being done by surrounding developments to provide more comprehensive results. 41  A way must be found to incorporate the development wants/needs of the surrounding 42 communities as stated in the KCDP with the protection efforts/requirements that the Park 43 works to ensure. 44  There is a very important aspect that to be understood, the water recharge rate and how 45 that affects the aquifer. 46 The meeting took a recess at 2:50 and resumed at 2:56 47 Department of Water Supply/Waimea Water Service 48 Steve Bowles and David Barnes provided the Action Committee with an update of the Kona 49 districts unique water resources and services. 50  Knowledge is collected over time and constantly– we can plan two ways – operate in fear 51 and regulate or we can plan in knowledge 52  Keauhou Hydralogic refers to a calculation area and includes multiple aquifers and utilizes 53 several factors to provide information for the sustainable yield/water resources in a certain 54 area and are modified as new information is discovered. 55  An important resource plan that is still relevant today is the Keauhou to Kailua Plan done 56 in the 1991. The plan notes that potable water is being brought in from Keauhou into 57 North Kona. There is a zone indicating the limits of a basal lens however this has now 58 become a area for high level water drill sites. 59  Because of lava flows from Hualalai there have been indications that there seems to be a 60 hybrid water system in the North Kona district – where there is artisian water under 61 pressure at a depth under tracite flows, high level water, and lower slope waters/ground 62 basal level water. These indication leads to a tentative determination that there are 63 multiple aquifer conditions within the Keauhou Hydralogic forming a very complex system 64 that are still being investigated. 65  Important information source for the sharing of current knowledge is the Kona Water 66 Roundtable. 67  State Water Commission has a state-wide policy of decision making based on sustainable 68 yield (which is still being investigated/questioned) and will take over management of the 69 aquifer unit when the pumpage reaches 90% of the sustainable yield. 70  The development (e.g. housing) that has been established in the area re-charges the aquifer 71 systems. The data has not been analyzed on the full impact of the re-charge to the aquifer. 72 Questions and Comments include: 73  Clarification of what the differences of water quality of the water from the high level water 74 and the basal lens. 75  Water demand needs to be determined based on two factors – meter track of existing 76 water usage and future population growth and not based on zoning based. 77 Page 2 of 5
