SBxvicas LABORATORY The laboratory provides daily analytical monitor- ing of plant wastewater to ensure the plant is in compliance with federal, state, and local require- ments. The labo- ratory also assists the Operations Section with plantprocesscon- trolanalyses,asre- quested, and per- forms analyses as neededforspecial projects and for otherCitydepart- ments. The labo- ratory also per- forms analytical services for indus- trial waste moni- toring, for the Sludge Manage- ment program, and for the Can- neryWaste Man- agement Facility. The laboratory performs 14>000 analyses and tests 500 wells each STAFFING year. Since plant start-up, laboratory staff has increased from a supervisor and two technicians to a supervi- sor, an environmental analyst, four technicians, two journeymen (Technician III's), and two ap- prentices (Technician II's). The laboratory is staffed seven days a week with one technician working weekends. Weekend duty rotates among technicians every four weeks. FACILITIES AND EQUIPMENT The 2,300-square-foot analytical laboratory is lo- cated inthe Administration Building and is shared with the industrial monitoring staff. Following are the major pieces of analytical equipment used by the laboratory: • Atomic Absorption Spectrophotometer This analyzer is a Perking Elmer 3030, with an HGA 500 graphite furnace and autosampler and MHS-10 mercury/hybride system. The spectro- photometer isused toanalyzethe metals contained in sludge, soil, plant wastewater, industrial waste, cannery wastewater, and groundwater at the Sludge Management Facility. • Carbon Analyzer The new carbon analyzer is a Dohrmann DC-80 and is used primarily to analyze the total organic carbon contained in cannery wastewater and the groundwater at the Cannery Waste Management Facility and the Sludge Management Facility. • Block Digestion System The Tecator Block Digestion System is used to analyze total kj eldahl nitrogen in samples of sludge, soil, groundwater, and cannery wastewater. • Ion Analyzer The Lachat Flow Injection Analysis Autoanalyzer is used primarily to analyze samples of sludge, groundwater, cannerywastewater, andplantwaste- waterfor nitrates and chlorides. DATA MANAGEMENT The laboratory uses a PC-based laboratory infor- mation system to handle data management. All sample s, except for routine plant samples, are logged into the system and recorded with sampling data, preservative information, andtestingrequirements when they arrive at the laboratory. When testing is completed, labels are printed for the sample containers, and reports are generated. The system was designed by Wastewater Division staff using dBase III software.
