The Manager-Chief Engineer said that DWS could take a good look at the scope of the work, and probably could include the basal wells as well as the high-level wells. This could include both North and South Kona, he said. Mr. Uyeda said he is not a geologist; he asked if it made a difference whether all of the wells were included. He asked whether DWS should concentrate on the high-level wells, which may not affect the basal water. He said he did not know; that was the reason for his question. The Manager-Chief Engineer said that DWS definitely does not know, and the idea is to try to know. The Deputy said DWS could incorporate some kind of simultaneous monitoring of a down-gradient basal source, as well as the high-level water. The reason that the basal wells were not initially included is that DWS is monitoring the basal wells for chlorides in-house. However, Mr. Uyeda’s suggestion is a good one, and DWS can do simultaneous monitoring. Mr. Uyeda said that maybe the monitoring could instead be in certain strategic points where there are upstream high-level wells; that might be really beneficial. The Manager-Chief Engineer said that it would be great to know whether or not a well is going to affect another well that is in the basal aquifer immediately downstream of that well, especially when DWS does pump testing, etc. He said that DWS could come up with a good strategy to get that kind of information. Mr. Uyeda asked how much above and beyond what DWS is already doing this new study would achieve, based on DOH requirements to report monthly. The Manager-Chief Engineer said that it would be a little bit more, because DOH only requires information such as chloride levels, and CWRM requires reports of DWS’s pumpage (i.e., not water level information). Knowing what DWS’s water levels are would be helpful, and the 12-month study would show whether or not water levels fluctuate. Water levels could be affected by the tides; the levels are definitely affected by rainfall. Mr. Robinson asked for confirmation that DWS will bid this project out, and the Department will show the Board the scope of the contract regarding what information will be requested from the contractor. The Manager-Chief Engineer said he was pretty sure that DWS can present the Board with the scope of work, to better understand what DWS is getting for this work. Mr. Robinson asked whether the information will include things like elevation of the water, salinity, etc. The Deputy noted that the Item involves a request for approval of a Professional Services Agreement, which is a different method of procurement. If the Board is not comfortable with approving at this time, the Department can come before the Board with a more defined scope before proceeding with this procurement. Mr. Robinson said he is in favor of approving, but he would just like to see the scope. The Deputy said DWS can certainly provide that. Ms. Lee Loy agreed that she wanted to see the scope, too. She said that Mr. Uyeda touched on a snapshot of the high-level wells vis a vis what is going on with basal wells in strategic locations; this will give the Board a good understanding of what is going on. She said that if that could be folded into the scope, it would make her feel a lot better. Page 13 of 27 Water Board Minutes 5-27-14 js
