ANALYSIS• After completing an analysis of the required sample data, it was determined that 17 of the 60 sites exceeded the .015 ppm regulation level. We are now required to mail notice to customers as outlined in the DER requirements, and are proceeding to do so. As can be seen from the attached lead and copper regulation summary, a corrosion control study must be complete by July of 1995; however, the Utilities Department is already 90% complete with this study in conjunction with Betz Entec chemical company (a manufacturer of corrosion;control chemicals). The Utilities Department is proposing to sole source its corrosion inhibitors from this company for one year to allow the completion of a full scale corrosion test into our distribution system. We are therefore seeking approval to sole source the County�s corrosion inhibitor and injection system from Betz Entec for both the South County and North Beach R.O. facilities at a yearly cost not to exceed $40,000.00 for South County and $6,000.00 for North Beach. Also, an additional $5,000.00 will be expended per plant for construction of concrete pads to support the bulk chemical storage tanks. The total cost of these systems will be offset by as much as 30% by a corresponding reduction in the use of caustic soda for pH adjustment at both plants. At the end of the one-year period (if all testing is positive), we will bid this service out through the Purchasing Department. All of our remaining smaller plants (i.e., North Beach, Rivers Edge, Pelican Pointe, Hobart Landing, Copeland Landing) are required to be sampled between July 1993 and December 1993, a program that we are proceeding with; however, we wish to install a full-scale corrosion inhibitor system immediately at both the South County R.O. and North Beach R.O. facilities. Installation at the North Beach facility should eliminate the possibility of any failed samples there. We are further proposing to have our water plant continuing services engineer, Camp Dresser & McKee Inc. (CDM), handle all plant permit modifications, as they are a recognized expert in this field. The upper limit for the permit modification services we are requesting is $5,000.00. RECOMMENDATION• The staff of the Department of Utility Services recommends that the Board of County Commissioners approve the following actions: 1) Approval to sole source the County's corrosion inhibitor systems as outlined above, and 2) Approval to utilize our water plant continuing services engineer to perform the required permit modification at both R.O. facilities. Fees for these services are not to exceed $5,000.00. Commissioner Macht questioned the PH level and Bill McCain, capital projects engineer, advised that right now we are running at 8.5 which is what has kept us in compliance. Utilities Director Terry Pinto felt the best recommendation is to let the water run awhile when it has not been turned on for awhile. Commissioner Adams objected to us being required to go into homes to see if they have high lead levels in their plumbing and she hoped that they don't come back at some time in the future and ask us to go into every home. She felt this is just another case of being overregulated. Next thing you know, we will be asked to go into peoples' homes to see if there is any radiation leaking from their microwave ovens. Director Pinto stressed that this is not just a state requirement, it is a national effort. ON MOTION by Commissioner Eggert, SECONDED by Commissioner Adams, the Board unanimously approved Items #1 and #2 as set out in the above staff recommendation. C, MAR - 9 1993 BOOK 88 F.gF 1® 8
