Item #18 CITY OF COLTON AGENDA REPORT FOR THE COLTON UTILITY AUTHORITY MEETING OF MARCH 15, 2005 TO: HONORABLE CHAIRPERSON AND UTILITY AUTHORITY MEMBERS FROM: ERIC R. FRASER, DIRECTOR OF WATER & WASTEWATER OPERATIONS SUBJECT: PURCHASE OF 1,200 CUBIC FEET OF ADDITIONAL PUROLITE A-530 RESIN FOR WELL NOS. 15 AND 17 PERCHLORATE TREATMENT SYSTEM DATE: MARCH 11, 2004 BACKGROUND: Two wellhead treatment systems that remove perchlorate to levels below the State of California Action Level of 6 parts per billion were installed to treat the water produced by three wells that supply water to the City. These systems use an ion -exchange resin process to remove the perchlorate. Each system consists of four (4) tanks and the resin must be replaced when fully saturated with perchlorate. On October 18, 2004 The Water Department had an informal open bid for Tanks 1 & 2 to replace the resin for Well No. 24. The award was given to GE BETZ, Inc in the amount of $90,000. The initial 600 cubic feet of Purolite A-530 resin was purchased on a trial basis and City staff found the results to be favorable. The city also had a formal bid opening on November 11, 2004 for Wells 15 and 17, which included a Bid item for the purchase of additional resin if needed. The items included the costs for labor, transportation, removal, disposal and installation of Purolite A-530 Ion Exchange Filter Resin. GE BETZ was the lowest bidder for the additional purchase of resin in the amount of $198,000. DISCUSSION/ANALYSIS: Well No. 24 now needs the other 600 cubic feet of resin because Tanks 3 & 4 have reached their adsorptive capacity and is rapidly reaching the state action level for perchlorate.
