S-K-F CSD Laboratory Division
Functions
The S-K-F CSD laboratory has two distinct but overlapping functions -
sampling and analysis of a variety of environmental samples, and implementation
of the District’s federally approved pretreatment (or industrial source
control) program. The functions are carried out by a staff of four, which
includes the Laboratory Director and three Environmental Technicians.
Sampling and Analysis
The laboratory is certified by the State of California, Department of Health
Services Environmental Laboratory Accreditation Program (ELAP Certificate No.
1648) for the following Fields of Testing:
FoT 102 Inorganic Chemistry of Drinking Water;
FoT 108 Inorganic Chemistry of Wastewater.
Approximately 20,000 analyses are performed annually on
about 4,000 environmental samples. About 40% of the samples collected are
treatment plant process samples, and the analyses are performed to assist the
Treatment Division with treatment plant process control and to determine
compliance with the District’s Waste Discharge Requirements, issued by the
Regional Water Quality Control Board. About 35% of the samples collected are
industrial discharge samples. Most of these samples are taken to ensure fair and
equitable industrial billing, but a significant number are taken to ensure
compliance with pretreatment program requirements. Various potable water samples
are taken for microbiological and chemical analyses. Approximately 20% of all
laboratory analyses are for quality control alone, and include performance
evaluation samples, replicate analyses, and “spiked samples”.
Pretreatment Program
 The District’s pretreatment program has been developed and implemented to
prevent the introduction of pollutants which may interfere with the treatment
process or pass through the treatment plant, to maintain the high quality of
biosolids produced by the treatment process, and to protect District employees
from chemical hazards. The program has been approved by the Environmental
Protection Agency and the Regional Board, and includes the following features:
1. Identification and permitting
of industrial users;
2. Regular monitoring of industrial dischargers to determine compliance with the
District's
Sewer Use Ordinance;
3. Enforcement of Sewer Use Ordinance;
4. Quarterly and Annual Reports to regulatory agencies.
Implementation of this pretreatment program accounts for
about 50% of laboratory resources.
