EXHIBIT A <br />SCOPE OF WORK <br />A. SAMPLING <br />1. BACTERIOLOGICAL OUALITY <br />a. Routine: Samples shall be collected by the Consultant, in appropriate <br />sterilized bottles to which a chlorine reducing agent has been properly added, on <br />a weekly basis at 50 designated sample points (Table 1). <br />Total coliform analyses will be conducted using either the multiple tube <br />fermentation method analyzing a minimum of 100-m1 of water either with using <br />5-tube 20-m1 portions or 10-tube 10-m1 portions, the membrane filter technique, <br />the presence/absence (P-A) coliform test, or the minimal medium (Coliform) test. <br />Reporting of positive samples shall be based on the presence or absence of <br />coliforms in each sample rather than an estimation of coliform density. <br />Upon detecting that either a routine or repeat sample is either total coliform or <br />fecal coliform positive, or a sample is invalidated due to interference problems, <br />the Consultant shall notify the City within twenty-four hours. To complete the <br />notification, consultant must contact a live individual. Voice mail and faxed <br />notifications will only be a secondary means of notification. The appropriate <br />contact person for the City is the Water Services Quality Inspector at (714) 647- <br />3341 or the Water Services Quality Coordinator at (714) 647-3316. When voice <br />mail is used to leave a message, the Consultant shall contact the City's Dispatch <br />Office at (714) 647-3380 between the hours of 7:00 a.m. and 3:30 p.m. If <br />notification is required during a weekend or holiday, the Water Services Quality <br />Inspector should be contacted at (714) 371-6779. In addition, a copy of the <br />City's Emergency Notification Plan (Attachment A) is attached. <br />In the event that the Consultant is unable to contact the City within 24 hours, the <br />Consultant shall notify the Department of Public Health, Drinking Water Field <br />Operations Branch, Santa Ana District, at (714) 558-4410. <br />Upon detecting that a routine or repeat sample is total coliform positive, the <br />Consultant shall perform a fecal coliform test. <br />The Consultant shall, within twenty-four hours after notifying the City that a <br />single routine sample is total coliform positive, collect three repeat samples. One <br />shall be from the same total coliform positive sample point. The other two <br />locations shall be determined by the City, one to be located within five service <br />connections upstream and the other within five service connections downstream <br />of the total coliform positive sample point (Table 3). <br />If total coliforms are detected in any repeat sample, the Consultant must within <br />twenty-four hours, after notifying the City that a repeat sample is total coliform <br />positive sample, collect another set of repeat samples from the same locations.
