METHODS DEVELOPMENT AND QUALITY ASSURANCE RESEARCH LABORATORY NATIONAL ENVIRONMENTAL RESEARCH CENTER, CINCINNATI, OHIO The EPA laboratory in Cincinnati is responsible for the development, selection, and evaluation of Measurements being taken at Spectrophotometer at Methods Development and Quality Assurance Research Laboratory. methods for the analysis of water and wastewater and the development of quality control systems for evaluating and maintaining the reliability of laboratory data. Agency test procedures for the National Pollution Discharge Elimination System, the monitoring of water quality, and the identifi- cation and measurement of toxic pollutants are the special responsibilities of the laboratory staff. Because of EPA concern for data used in decision making and regulatory actions, an ac- tive program of quality assurance has been initiated throughout the Agency laboratories. Other laboratories providing results on waste discharges and water quality are also within the scope of the quality assurance program. ------- Five branches compose the laboratory organi- zation. These are: • Physical and Chemical Methods « Biological Methods • Instrumentation Development • Radiochemistry and Nuclear Engineering • Quality Assurance and Laboratory Evalua- tion The Physical and Chemical Methods Branch has sections for Inorganic, Organic, and Ad- vanced Instrumental Analyses. The Inorganic laboratory group is responsible for research leading to improved techniques for mineral, nu- trient, and heavy metal constituents in water and wastewaters. Emphasis is on rapid instrumental approaches including automated analysis, specific ion electrodes, and combustion procedures for organic carbon and trace metals. The current demand for reliable methods for waste monitoring at the low concentrations consistent with ade- quate treatment is a special challenge for this section. Organic methods research involves procedures for a wide variety of industrial organic chemicals in effluents, including known and potentially carcinogenic materials. Reliable methods for new pesticides and herbicides, for the identification of spilled oil in rivers, lakes, and estuaries, and the characterization and measurement of trace organics in water supplies are urgently needed. Precise determinations and unambiguous identi- fications are required for regulatory actions by the Agency. The Advanced Instrumentation Section deals with the application of sophisticated systems for laboratory analysis. Instruments which at present may be available only to relatively large labora- tories can become routine equipment through application studies and systems design. An ex- ample of this is the gas chromatograph/mass spec- trometer, which has become a standard tool in EPA for organic identifications. The Advanced Instrumentation Section develops and expands these types of instruments, providing method- ology to other laboratories of the Agency. The Section is also involved in the development of a computerized system for laboratory automation which will form the basis for more rapid, reliable sample processing, analysis, and data handling in EPA regional laboratories. In the area of natural sciences, the Biological Methods Branch, through its Virology, Micro- biology, and Aquatic Biology Sections, seeks to improve procedures for the collection, enumera- tion, and identification of micro and macro orga- nisms in water supplies, ambient waters, and municipal wastes. The importance of viruses as health hazards to humans requires ability to rapidly isolate and quantify these organisms in a variety of environmental media. Present meth- ods are tedious and time consuming and the Virology Section is committed to the development of improved and standarized laboratory proce- dures which will permit rapid assessment of hazard. These procedures must be capable of isolating a few microorganisms in large quanti- ties of water, because of the likelihood of disease transmission by relatively low numbers of viruses. Effluent standards and water quality criteria include limitations on the number of "indicator" organisms (total and fecal coliforms) which may be present. The Microbiological Section is re- sponsible for improved techniques for the enu- meration of these organisms, as well as patho- gens such as salmonella. The emphasis is on rapid procedures which can be used in labora- tories with limited technical personnel. The development of quality assurance techniques to assure reliable microbiological data is also the concern of this section. The Aquatic Biology Section develops and evaluates methods for use by Agency biologists in field and laboratory studies carried out to detect violations of water quality standards, evaluate the trophic status of surface waters, determine long-term trends in surface water quality, and measure the toxicity of specific pollu- tants or effluents to individual species or com- munities of aquatic organisms. The methodology developed by this section includes: sample col- lection, sample processing and counting, identi- fication of aquatic organisms; biomass deter- minations; measurement of metabolic rates; measurement of toxicity, bioaccumulation and biomagnification of pollutants; and biological data processing and evaluation. The Instrumentation Development Branch is responsible for the research on new monitoring instrumentation for water and wastes and for the evaluation of commercially available effluent monitoring equipment. Emphasis is placed on instruments which will measure one or more constituents of the waste on a continuous basis and record the data for later analysis or transmit the information to a central station. The relia- bility of the equipment is evaluated under envi- ronmental stress in the testing laboratory, then installed in an actual monitoring mode for fur- ther examination. The ultimate objective is to guide the Agency in the selection of its own monitoring instruments and to determine the usefulness of data submitted by a discharger when similar equipment is used. Through the testing of a variety of instruments the most desirable design and operation can be identified, leading to detailed specifications and guidelines for future equipment procurement and utilization. In its evaluation program, the measurement principle, the sensor design, the internal elec- tronic configuration, and the data processing and transmission capabilities are assessed. The Branch has the facilities and staff to examine each component individually and collectively and to identify the strengths and weaknesses of in- ------- strument design ad operation. Evaluation reports are prepared and published on each instrument tested. Because of the increasing use of nuclear re- actors for power generation, methods for the assessment of environmental impact of reactor operations and waste handling are necessary. The Radiochemistry and Nuclear Engineering Branch is charged with selecting, developing and demonstrating analytical methods for radionu- clides in a variety of environmental media. The staff of the Branch studies the transport of radionuclides in the vicinity of reactors and makes field studies to define the impact of pro- posed new nuclear power plants and nuclear fuel processing facilities. Procedures for the accurate measurement of the amount and types of radio- nuclides in plant effluents are developed and standardized by the Branch. Technical assistance is provided to other elements of EPA in the assessment of radioactivity levels in the envi- ronment. A variety of activities related to improving and monitoring the quality of laboratory data are carried out by the Quality Assurance and Labora- tory Evaluation Branch of MDQARL. Inter- laboratory studies leading to the validation of Agency test procedures for water quality and waste constituents are conducted. These studies, utilizing many laboratories from the public and private sectors, provide data on the precision, accuracy, and dependability of approved methods and assist in the interpretation of monitoring data. Reports of these studies provide information to both analysts and decision makers and help to identify needed improvement in laboratory methodology. The Branch develops intralaboratory quality control procedures to assure the reliability of analyses and data handling and provides check samples for the evaluation of analyst perform- ance. A series of quality control samples are distributed by the Branch to laboratories engaged in water and waste analysis. These samples, available without charge, enable the laboratory to measure its performance against known pollu- tant levels and to highlight problem areas in analytical methods, equipment, or techniques. Through both inhouse and extramural projects, the Quality Assurance and Laboratory Evaluation Branch develops systems for the evaluation of laboratories, including inspection forms, test protocols, check sample performance evaluations, and approval mechanisms. These systems, used to measure laboratory capabilities at the Federal, state, and local level, assist in establishing the reliability of environmental data banks. As pres- ently conceived, these programs may lead to the approval of specific laboratories for environmental measurements required by current EPA regula- ' tory activities. The present staff of the MDQAR Laboratory numbers 90, of which 52 are professional scien- tists and engineers. At the present time the staff is in three separate buildings in Cincinnati, with the laboratory headquarters at 1014 Broadway. When the new National Environmental Research Center building is completed in October, the laboratory will be consolidated into the new and improved physical facility. The MDQAR Laboratory has an increasing his- tory. It was established in 1957 as the central laboratory for the National Water Quality Network of the U.S. Public Health Service. With the for- mation of the Federal Water Pollution Control Administration as the parent organization, and the transfer of surveillance responsibilities to regional offices, the laboratory assumed its pres- ent role as a research component under the title of Analytical Quality Control Laboratory. In Sep- tember 1973, the present MDQARL was formed, as part of the National Environmental Research Center-Cincinnati, incorporating the old AQCL with virology and radiochemistry elements from other Cincinnati organizations. Throughout its history MDQARL has made sig- nificant contributions to the science of water and waste methodology. Among these are the application of the carbon absorption systems for monitoring organics, methods for chlorinated hydrocarbon pesticides, automated colorimetric analyses, use of the emission spectrograph for multielement measurements, procedures for the identification of oil, methods for the determina- tion of mercury, the application of gas chroma- tography/mass spectrometer (GC/MS) to organic identification, the development of artificial sub- strates for the collection of aquatic organisms, the preparation and publication of taxonomic keys for organism identification, methods for the isolation and identification of viruses and patho- gens in water, the publication of specifications for integrated water quality monitoring instru- ments and data transmission systems, and the conduct of definitive studies of the precision and accuracy of analytical methods. Current research activities include improved methods for cyanide, phenols, pesticides, and other toxic pollutants, development of new techniques for GC/MS, quantitative detection of viruses, rapid methods for pathogens and indicator organisms, new and improved tech- niques for biological investigations, evaluation of effluent monitoring systems, measurement of gaseous radionuclides in the vicinity of nuclear facilities, validation of Agency methods for chemi- cal and biological measurements, and the devel- opment of new check samples for a variety of laboratory programs. In order to maintain awareness of standardiza- tion activities by other groups, the laboratory staff participates in the preparation of Standard Methods for the Examination of Water and Waste- water, Committees D-19, D-22, E-2, and E-36 of ------- ASTM, the International Standards Organization, and the World Health Organization. A wide variety of publications, described in a brochure, are available from the laboratory. Among these are "Methods for Chemical Analysis of Water and Wastes" (described in another article in this Newsletter), "Biological Field and Laboratory Methods," "Methods for Organic Pes- ticides in Water and Wastewater," "Handbook for Analytical Quality Control in Water and Waste- water Laboratories," and a series of reports on method validation studies. The laboratory pub- lishes and distributes its own newsletter, called "Analytical Quality Control."
