&EPA United States Environmental Protection Agency Office of Research and Development EPA/6QQ/K-92/QQ6 July 1992 The Federal Technology Transfer Act Environmental Monitoring Technologies Opportunities ------- The Federal Technology Transfer Act Environmental Monitoring Technologies Opportunities This brochure is the second in a series of information packages prepared by the U.S. Environmental Protection Agency (EPA) to promote cooperation with industry and academia under the Federal Technology Transfer Act (Public Law 99-502). The first publication in this series, entitled "Opportunities for Cooperative Biosystems Re- search and Development with the U.S. EPA" is available through EPA's Center for Environmental Research Information (CERI) listed in the back of this publication. Commitment to work with the private sector To enhance and maintain a clean environment while improving the nation's productivity, the U.S. EPA is joining with private industry and academia to seek new, cost-effective technologies to prevent and control environmental pollution. Both the U.S. government and the private sector can play key roles in restoring and protecting the environment, as well as fostering effective competitive markets for U.S. business. EPA Administrator William K. Reilly captured the essence of EPA's FTTA effort when he stated "The international market for environmental goods and services is more than $200 billion and growing at 5 percent a year. For smart U.S. companies, our federal laboratories can be a source of innovative technologies, giving them new opportunities and a competitive edge in the global marketplace." Other mechanisms EPA's Research Office has been at the forefront in working with U.S. Industry. In addition to EPA's efforts under the FTTA, the Superfund Innovative Technology Evaluation (SITE) program allows EPA to work with private sector firms to develop important cost and performance data on hazardous waste clean-up technologies. EPA has a successful Small Business Innovative Research (SBIR) program which helps start-up companies. EPA established the National Environmen- tal Technology Applications Corporation (NETAC) with the Univer- sity of Pittsburgh Trust to assist entrepreneurs with business develop- ment. Printed on Recycled Paper ------- The U.S. Environmental Protection Agency (EPA), academic institutions, and private industry are develop- ing new, cost-effective technologies to prevent, monitor, and control pollution. These technologies eventually lead to commercial monitoring services that focus on sampling, analysis, data interpretation, field and labora- tory methods development, and analytical quality assur- ance, to name a few. Media tested range from soil, air, and water to plant and animal tissues. Accurate monitor- ing is essential to the prevention and control of pollution. Isolated efforts to solve environmental problems have been stymied by a lack of resources, such as scientific experts in particular fields, highly specialized equip- ment, and avenues for evaluating new technologies. In 1986, the Federal Technology Transfer Act (FTTA) removed many of the legal and institutional barriers that earlier had prevented government and the private sector from collaborating to develop and market new environ- mental technologies. Under FTTA, government scien- tists can enter into cooperative research and develop- ment agreements (CRDAs) with industrial or academic partners. These agreements will, according to the Act, foster the technological and industrial innovation that is "central to the economic, environmental, and social well- being of citizens of the United States." ------- What can industry gain from signing a CRDA with EPA? Access to high-quality science and facilities. The monitoring laboratories, under the Office of Research and Development (ORD), have direct experience with the regulators and the regulated community. Their combined experience covers monitoring methods for pollutants in soil, air, and water. Communication between government and private sector. The basis of knowledge within the monitoring laboratories includes historical perspective, current interests, and future plans. This pointed familiarity allows the government scientist to work with the industry or academic partner to benefit both parties. An opportunity to access international markets. Recent international monitoring agreements call for pollution assess- ment in every foreign city with a U.S. Embassy. By working with the EPA to provide cutting-edge monitoring technologies to the marketplace, industries can achieve international visibility. Exclusive agreements for developing new technologies. Under some CRDAs, companies are given exclusive licensing rights for the commercialization and marketing of new technologies. Until recently, industry had little incentive to cooperate with federal laborato- ries because any technologies developed during joint research remained in the public domain for all to use. Now, exclusive rights canbe negotiated for some projects, though other arrangements are possible, depending on the type of CRDA that is established. The advantages of collaboration have prompted EPA and industry to set up CRDAs in areas ranging from monitoring air pollution to oil spills cleanup. Monitoring technologies, such as radon measurement devices and personal exposure dosimeters, offer promising opportunities for collaborative research and profitable commercialization. Pollution prevention is currently of great interest to industries wishing to reduce^ontamination at all stages of manufacturing processes. Coping with existing regulations portends the dawn of industrial awareness and environmental concern. It also suggests lucrative avenues of research that are mutually beneficial to regulators and the regulated community. Environ- mental monitoring technologies can identify successful pollution prevention avenues, provide methods for their appraisal, and compare approaches. ------- JDevelpp the Technology Assess Need Search Literature Plan Study Compare Methods ------- Use the Technology Demonstrate Usefulness Implement the Technology Transfer the Technology Document the * Technology ------- Environmental Monitoring: Measurement with Meaning Environmental monitoring technologies allow the researcher and remediator to determine the identity and extent of contamination in matrices as diverse as air, water, soil, and solid waste. By knowing the concentration of contaminants in a sample, managers can thoughtfully decide whether to continue or change a process. Smokestack measure- ments, for example, give critical information about the off-gassing at a manufacturing plant. Soil-gas measurements allow researchers to identify and trace a plume of volatile organic compounds (VOCs). Ground water monitoring gives a clear view of the underground migration of a contami- nant, from its source to its potential release into the environment. New methods may apply to individual use and, therefore, impact a wide commercial market. Personal exposure monitors (PEMs) are being developed for workers who may be exposed to injurious chemicals, radiation, or microorganisms. Small and inexpensive PEMs use immuno- chemical technology to provide information about individual exposure. Indoor air monitoring is of growing commercial and residential interest. ------- Methods for measuring the types and levels of microbiological and chemical contamination in ambient air are currently being investigated, at the EPA's monitoring laboratories. Additionally, the laboratories provide the Agency and a growing user community with thoughtful evaluations of innovative technologies that promise to facilitate the environmental monitoring challenges of the future. This familiarity with current methods positions the monitoring laboratories as wise assessors of the potential commercial value of emerging technologies. ------- EPA's Interest in Monitoring Technologies The EPA assesses the nature, extent, and impact of contamination in all media. This monitoring effort begins with a thoughtful experimental and sampling design. The design of an environmental study is based upon the data requirements of the site and the criticality of exposure to the specific contaminants. Environmental monitoring generally follows the protocol: plan, screen, characterize, analyze, remediate, assess, close. That is, after the plan is agreed upon by the concerned parties, an initial screening study helps isolate the areas of highest contamination. These areas are subsequently characterized in greater detail and this detail takes the form of data that must be translated to information by analysts. The development of sophisticated yet user-friendly software packages is another area of inter- est to the EPA and one which should hold commercial promise as indus- tries become increasingly aware of environmental considerations. Soft- ware packages can bring complex technological capabilities to non-expert users in areas ranging from geostatistics to multivariate analysis. The best remediation process is chosen based on the type and extent of contamina- tion and the threat to human health. Monitoring assesses the remediation process to ensure that contamination is not being transferred from one phase to another (e.g., if contaminated soil is tilled, care must be taken to measure the off-gassing of VOCs). The closure of a hazardous waste site (and its removal from the National Priorities List, in the case of Superfund) ends the environmental monitoring protocol. The EPA has responded to a number of special monitoring projects, including the Love Canal incident described on the following pages. The EPA is very active in the research, development, and application of innovative monitoring technologies. One area of monitoring research is the development of assessment methods and devices for determining human exposure. Innovative work in the advancement of sensitive, spe- cific dosimeters is ongoing at the laboratories. These and other technolo- gies are of interest to the industrial and academic communities for similar or separate applications. It is this joint interest that is addressed by the establishment of CRDAs between EPA and the private sector. ------- Comprehensive Monitoring at Love Canal The EPA was directed to respond to a state of emergency that was declared at Love Canal, NY, and to assess the extent and degree of environmental contamination that was directly attributable to the migra- tion of hazardous substances into the nearby residential area. The Love Canal was originally intended as a water channel for generating hydro- electric power in the 1890s. When the canal was abandoned, the area was unused until the 1940s when it was purchased by a chemical company and used for the disposal of various products ranging from metal chlorides to chlorobenzenes. The canal was filled, capped, and, subsequently, residen- tial and commercial development occurred. In 1975, residents began to notice the legacy of buried contamination. The study designed and conducted by the EPA fulfilled a threefold mission: To determine the level and extent of chemical contamination. To assess the short-term and long-term implications of ground- water contamination. To provide an assessment of the relative environmental quality of the area. ------- During a three-month period, more than 6800 samples were collected and analyzed, pediment -samples were collected from creeks, rivers, sanitary sewers, "storm drains, sumps, and from an on-site collection facility. Ground-water samples were obtained from 136 monitoring wells and from bedrock aquifer wells. Water samples were taken from rivers, creeks, sewers, and from domestic water supplies. The procedure used for collecting soil samples was designed to maxi- mize the probability of detecting subsurface migration of chemicals through soil. The monitoring program was also designed to determine the presence of radionuclides in the Love Canal area. Air monitoring was continuously conducted in 65 residences. Ambi- ent air and basement air were sampled and monitored in studies parallel- ing the indoor air studies. The result of the intense monitoring effort at Love Canal was a multilaboratory, multidisciplinary report that detailed the history of a pollution source. Based on the final report, executive decisions were made to relocate residents who wished to move. Remedial activities at the Love Canal have enabled residents to move back into portions of the neighborhood. ------- Methods for Sampling Ground Water A good sampling procedure yields samples that represent the popula- tion of interest, does not compromise the purpose of sampling, and contributes to the accuracy of analytical results. Research and develop- ment on methods of sampling ground water continues at the Robert S. Kerr Environmental Research Laboratory (RSKERL), Ada, Oklahoma, and a few studies are given here as examples. These efforts could be enhanced by CRDAs with industry and other institutions. Sampling Ground Water for Metals Analysis RSKERL scientists and their collaborators studied sampling methods for metals analysis at a copper mining waste site and two chrome metal facilities. Research at the waste site showed that the use of a high-speed submersible pump yielded cloudy samples, large suspended particles, and a great difference in metals concentrations compared to the use of a bladder pump operated at low speed. However, the high-speed samples equili- brated after one or two casing volumes. Research at one chrome site showed that bailers ineffectively collected metal samples. The use of low- speed purging with a peristaltic pump consistently yielded good samples, even from wells dug in fine-textured soil. Follow-up work at a chrome plating facility evaluated these sampling devices. Further validation studies, testing of other sampling devices, and innovative methods are needed to sample ground water for metals analysis. Verifying Mechanical Integrity of Injection Wells To ensure protection of drinking water from contamination from underground injection operations, RSKERL develops technologies using eight research wells at the Mechanical Integrity Test Facility (MITF). The wells range in depth from 190 to 1,575 feet. Studies at the MITF improved methods to test cement behind casing in injection wells and produced a nuclear activation technique to detect water flow behind pipe. Companies come to this unique facility from all parts of the United States and Canada to test their latest downhole technology. Additional well studies are encouraged at the MITF through CRDAs. Advances in Solids Sampling at Hazardous Waste Sites Traditionally, remediation designers use water samples, which imper- fectly describe the complex ecology of an aquifer, to monitor new systems. 10 m^mm^^m^samaamm^mmmm m •• mmwmmt •• mini ------- To obtain information necessary to characterize a hazardous waste site and to track the effectiveness of a remediation design, RSKERL researchers proposed more {difficult ;bp promising method—collecting subsurface sediment samples. Conventional drilling and coring to obtain subsurface samples works well when the sediments are cohesive and stable. Re- searchers have developed a clamshell-shaped, capped auger fitted with an internal sand seal and a wireline piston sampler to collect difficult sedi- ment samples. These new tools and methods are being evaluated at various sites, but additional studies, methods, and tools need to be devised for accurate sampling of sediments like these. Quality of Drinking Water from Deep Aquifers Some states require monitoring of shallow aquifers, but not of pres- ently unused deep ones. RSKERL researchers explore alternative meth- ods to determine if the chemical quality of ground water is being altered in deep aquifers, because waste may enter them through injection wells. Drilling monitoring wells to the base of an underground source of drink- ing water is not economically feasible. Among other possibilities is the evaluation of "electric logs" (records from monitoring devices lowered into wells). Studies are needed to develop a valid method for determining water quality from these records. A second approach might be to investi- gate the feasibility of using a pulsed neutron or another logging device to determine water salinity, for example, in geologic formations. The same questions surrounding electric logs—accuracy in determining water qual- ity —must be addressed. Field testing is also necessary to validate both approaches and their applicability, with the final step being that of testing the technology to monitor deep aquifers. ------- Monitoring the Air: Vital Research EPA's interest in air monitoring ranges from vehicle exhaust fumes to smokestack emissions from manufacturing processes. The Atmospheric Research & Exposure Assessment Laboratory (AREAL) at Research Tri- angle Park, NC, is exploring innovative monitoring methods that will streamline and simplify air sampling protocols yet retain the sensitivity of traditional methods. Several research interest areas are summarized here. Agency involve- ment and industry concern merge with public interest in these critical technologies that can help safeguard the integrity of the air we breathe. Particulate monitoring that encompasses aerosol physics, sampler inlet design, and diagnostics can be applied to the monitoring of indoor and outdoor air for particulate-bound toxicants and biological pollutants. Development interests also include technologies for the generation and monitoring of aerosols. These technologies can also be used to develop ambient and personal monitors for detection and measurement of human exposure. Volatile organic compound (VOC) analysis is important for assessing sources causing ozone pollution and because many VOCs are considered toxic to humans. AREAL has already established mutually beneficial CRDAs in this area. Interests include: automation of sampling and analysis equipment; enhancing the sensitivity, speed, accuracy, and reli- ability of the sampling/analysis equipment; improving sampling and analysis of polar VOCs; development of both passive and active samplers for monitoring personal exposures or ecological exposures; biologically- based or other thin-film methodologies for detection and analysis of exposure; and analysis of complex mixtures for health-based endpoints rather than chemical-by-chemical analysis. Gaseous and particulate emissions from source stacks present a complex and often hostile environment for measurement and monitoring. New techniques for analysis of multiple pollutants are needed. Continu- ous emission monitors and sampling systems that accurately gauge the emission flux and ambient distribution of pollutants are also needed. 12 ------- Emissions from area or complex sources such as lagoons, warehouses, or large industrial complexes are difficult to measure and to regulate. Concentrations and flux must be measured in three dimensions. These fugitive emissions offer a multidisciplinary challenge to chemists, physi- cists, and meteorologists. Current work includes the use of open-path monitoring combined with meteorological measurement of wind flux, and advanced methods of transport modeling. Approaches that offer real-time, multidimensional sampling and analysis are needed. Pollutants from automobiles contribute significantly to a variety of pollution problems. That contribution must be characterized well. Inno- vative methods for the direct measurement of non-methane hydrocarbon emissions are needed as are techniques to estimate better the on-road emissions of vehicles and real-time emission of vehicle fleets. Characterization of complex mixtures such as products of incomplete combustion, polycyclic organic materials, and polychlorinated biphenyls, is currently very expensive and time consuming. Cost-effective ap- proaches, e.g., using fuzzy logic, composite biological effects, or general- ized physicochemical response are badly needed. Exposure monitoring would benefit greatly from development of special sensors that combine rapid measurements of toxic pollutants with detection of location and activity. New research areas for air monitoring are underway at AREAL and many of these are good opportunities for CRDAs with the EPA. 13 ------- A Monitoring Partnership Results in New System The AREAL has an interest in innovative methods for the determina- tion of pollutants in air. Perkin Elmer Corporation is interested in new instrument designs that meet or exceed the needs of the regulated and regulatory community. These two facts led to a CRDA partnership. These common interests and similar approaches led investigators from these laboratories to pursue and establish a CRDA for the develop- ment and evaluation of a threefold approach to the sampling and analysis of ambient air: Solid adsorbents for organic compounds that are typically found in ambient air Gas chromatographic systems capable of analyzing air samples from canisters Automated chromatographic systems for ambient air monitoring The AREAL/Perkin Elmer CRDA resulted in the development of a new type of adsorbent-based sampler for the collection of volatile organic compounds from ambient air, a new sampler for sequential collection of short-term samples to measure temporal concentrations, and a thermoelectrically cooled, adsorbent-based preconcentrator for VOCs. Commercial systems resulting from the second and third efforts should be available by the end of 1992. One of the advantages of CRDAs is the speed with which a product can be marketed once it is developed. Concurrent evaluation by two research teams can streamline the testing procedure. Working together, government scientists and their industrial partners have solved these and other challenges that have troubled environmental workers for years. ------- Measuring Contamination The Environmental Monitoring Systems Laboratory at Las Vegas, Nevada (EMSL-LV) pioneers methods for measuring the extent of con- tamination at hazardous waste sites. Scientists use these techniques to characterize Superfund and other contaminated sites before and after remediation. In addition to developing the methods that are given here as examples, EMSL-LV seeks CRDAs with industry and institutions to develop new methods and tools to monitor the environment. Quality Assurance Quality assurance (QA) protocol is as important in the field as it is in the laboratory. The EMSL-LV develops QA methods that serve the data quality objective needs of particular studies. The ability to customize QA to fit the demands of the research is a vital scientific tool. The proper use of QA is critical to the success of a monitoring study. The need to know, with precision and accuracy, the value of generated data, leads scientists to investigate easy-to-use methods for determining these factors. Field- portable methods often rely on the use of site-specific or site-characteristic standards. These standards replicate the media of the samples and give a close interpretation of the reliability of the data. Advanced Analytical Procedures The EMSL-LV is a leader in the development and modification of advanced analytical procedures that are able to meet the needs of complex and subtle environmental samples. EMSL-LV performs rugged method evaluations that ensure quality in new, field-portable instruments. Ad- vanced methods in the areas of liquid chromatography - mass spectrom- etry, open-path Fourier transform infrared spectroscopy, and high reso- lution mass spectrometry are currently being investigated. Fluorescence and luminescence techniques are being used to analyze oil and related compounds. Innovative sample preparation procedures are being inves- tigated and developed that will accentuate reproducibility in all handling steps to ensure more precise results. The use of robotics is being explored and improved for special laboratory processes. Instru- 15 ------- mentation is being revolutionized as future users become more involved with the design and function of the standard laboratory equipment of tomorrow. Field-Portable X-Ray Fluorescence The mining industry first used field-portable X-ray fluorescence (FPXRF) devices as metal detectors. In recent years, EMSL-LV scientists have applied this technology at hazardous waste sites to quantify 18 of the 24 elements on EPA's Inorganic Target Analyte List. The field-portable unit, used with calibration standards from laboratory-analyzed samples, generates data of known quality. Its operational principle is based on the fact that atoms of specific elements fluoresce in a unique way after excitation. By bombarding a sample with energy, the instrument causes atomic electron instability. As the electrons "relax" to a stable energy level, the ensuing X-rays fluoresce. The detector senses and counts the spectrum of radiation, which is a "fingerprint" of the specific analyte and, on this basis, identifies the atom. Opportunities exist to make the FPXRF instru- ments smaller, more sensitive, and accurate. Field methods, including quality assurance procedures and site-specific standard requirements, also need development. Immunochemistry Current immunochemical work involves the analysis of chemicals, like polychlori- nated biphenyls (PCBs), nitroaromatics, and certain pesticides, that are difficult to analyze by other methods. Im- munochemistry incorporates antibodies that have been de- veloped for specific analytes, and includes such techniques as immunoaff inity and immu- noassay. Immunoaffinity preparations have great po- tential for "cleanup" of samples like dioxins. By rins- ing a sample over an antibody- treated surface, chemists can isolate particular compounds in the sample ------- 27 ------- that adhere to the antibody. The compounds are then eluted from the immobilized antibody and can be analyzed by chromatography or immu- noassay. Most field immunoassays use colorimetry to quantify com- pounds. Laboratory immunoassays use radioactive methods or fluores- cence, which have greater sensitivity. EMSL-LV studies show strong correlation between field immunoassays, laboratory immunoassays, and gas chromatography- mass spectrometry. Additional research and devel- opment is needed to expand the applicability of immunochemistry to many more chemicals of environmental interest. Remote Sensing - Monitoring at a Distance The monitoring laboratories are able to draw on a valuable resource — historical data. Much of this historical data is in the aerial photographic databases generated by remote sensing scientists. More recent advances in the field have expanded the capability to include geographic informa- tion systems, global positioning systems, and computerized enhancement of satellite data. The most novel areas of research include advanced software programs that allow the user to incorporate accurate data of a complex nature into a realistic assessment of the site. Soil-Gas Measurement The term "soil-gas" refers to the atmosphere in soil pore spaces. Volatile compounds, such as hydrocarbons, hydrogen sulfide, and radon, become part of this atmosphere by physicochemical processes. Of the 25 most commonly encountered contaminants at Superfund sites, 15 are amenable to detectionby soil-gas sampling. Techniques for measuring soil gases came from agricultural and petroleum studies early in this century, but only within the last 10 years has soil-gas measurement been used to screen environmental sites for hazardous chemicals. In one method, samples are collected by driving a probe into the ground and pumping the gases to the surface for capture and analysis. In another, passive method, a sampler containing a sorbent with an affinity for the target analyte is placed in the ground and later removed and analyzed. Soil-gas surveys can identify contaminants, their sources and extent. Survey results guide other sampling, such as soil boring and ground water monitoring wells, and can be used to make decisions on locations for fixed vapor wells for long-term ^monitoring. Further work is needed on basic research into soil- gas physicochemistry and statistical sampling design as well as the tech- nique and materials to improve field monitoring. 18 ------- Geophysics: A Key Step in Site Characterization Geophysical: techniques allow managers to characterize contami- nated sites with little disturbance to the subsurface. The methods gauge the physical properties of the subsurface, identifying cultural structures, such as pipes, and buried objects, such as waste drums. Generally the methods fall into six categories: Seismic (including reflection and refraction) Electric (including direct current resistivity and electromagnetic techniques) Magnetic Gravity Radiometric Ground-penetrating radar These measurements can be made on the surface of the ground, by airborne instruments, or in boreholes. By observing characteristics of the measured signal, the geophysicist estimates the size, shape, depth, and other characteristics of subsurface objects. Computer algorithms aid the process of interpretation. The equipment varies, but field-deployable units in all categories are used. A number of EMSL-LV research projects in geophysics offer fruitful avenues for field application. Cooperators are needed to develop the equipment and methods to use geophysics as a key step in site characterization. 19 ------- Monitoring Waters and Wastes - New Approaches The Environmental Monitoring Systems Laboratory in Cincinnati (EMSL-CI) is dedicated to methods research for the chemical, biological, and microbiological monitoring of waters and wastes, including studies of environmental stressors, biomarkers, toxicity testing, and biotechnology research. Research Containment Facility The Andrew W. Breidenbach Environmental Research Center (AWBERC) in Cincinnati has a Research Containment Facility (RCF) that is used for scientific research involving hazardous and toxic materials. It is the EPA's first high-hazard facility and features secured areas for employee protection, fire protection, and waste containment and disposal. Special care is taken to minimize employee exposure to hazardous sub- stances. The building features a special air system that ensures negative air pressure differential throughout the containment facility. The private sector, through a CRDA with the laboratory, could use the facility to conduct research and development involving hazardous substances. Biotechnological Monitoring: An EPA Goal Innovative monitoring methods are critical to the development of biotechnology processes because the effectiveness of the new technologies must be accurately measured and evaluated. Ongoing research at EMSL- CI will interest private sector researchers who are working on the state of the science in biotechnology. The technology of molecular genetics has revolutionized biology in the last 15 years and given environmental microbiologists new tools for monitoring harmful organisms in water and air. EMSL-CI researchers use these techniques, such as gene probes, polymerase chain reactions (PCR), and immunoassays to detect harmful microorganisms. Through CRDAs, instrumentation and technology for environmental sampling and moni- toring can be further developed. 20 ------- Gene Probes. EMSL-CI microbiologists use gene probes to analyze samples for harmful protozoa and viruses, Giardia and Cryptosporidium occur in contaminated natural waters, and it is important to trace them to the animal host of origin. Current methods for detecting these organisms through their cysts may overestimate their number, because the methods detect empty cysts. Gene probes, because of their great specificity for genetic material, detect viable cysts. EMSL-CI develops gene probes for deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) against these protozoa, and against viruses that infect humans, such as Norwalk and hepatitis A, which cannot be grown in cell culture. Gene probes can detect genetic material in samples having a background of up to a million unrelated chemical sequences. Messenger RNA synthesis from purified DNA can be detected and quantitated in amounts as low as 1 to 10 copies per cell. Through CRDAs, devices can be commercialized and field-tested from this research. After testing, the devices could be developed into gene probe kits for important protozoa and viruses. Chain Reaction Methods. EMSL-CI is conducting in-house research and sponsors extramural R&D to detect, enumerate, and determine the health effects of pathogens in the environment using the PCR technique. Nucleic acids, the components of DNA and RNA, are polymers or chains of chemicals. Many viruses can now be detected by making hybrids of them with gene probes, using PCR to amplify the genetic material, and identifying the viruses in 1 or 2 days. Water-borne pathogens of immediate interest for development of PCR technology are Legionella, non-tuberculosis mycobacteria, and vi- ruses that cannot be grown in cell culture. Methods that can differentiate species would greatly improve risk assessment of pathogen detection. A number of CRDAs for technology transfer could be made with the private sector to assess existing proprietary technology for these microorganisms. For example, a company or institution could thoroughly evaluate alterna- tive sampling methods compatible with PCR technology to identify microorganisms from a variety of environmental sources. Further, exist- ing methods could be compared to new methods of sample preparation and PCR methods. In addition, PCR environmental reagents and instru- mentation produced commercially could be evaluated for their efficacy, sensitivity, precision, and specificity. i 21 ------- Using Biotechnology to Monitor Indoor Air. Fungi of ten cause building-related illnesses, such as humidifier fever, hypersensitivity pneumonitis, and asthma. Identifying fungi can be difficult and requires specialized training possessed by few microbiologists. EMSL-CI seeks to identify fungi from indoor air within 24 hours without culturing the organisms. Needed are (1) a battery of gene probes for rapid identification of indoor-air fungi that cause human infection and (2) a screening test that does not require fungi culture. Through CRDAs, successful probes could be field-tested and commercially produced in kits. Animal Facility The EMSL-CI offers a well-equipped animal facility and the technical staff for conducting a full range of research in ecological toxicology, for using animal models to study infectious diseases, and to differentiate virulent and avirulent strains of opportunistic pathogens such as Legionella. The facility is equipped to handle aquatic and terrestrial organisms, including vertebrates and invertebrates. The EMSL-CI staff has particular expertise in carcinogenesis/mutagenesis and in reproductive and devel- opmental toxicology and a particular interest in biochemical and molecu- lar markers for documenting exposure stress effects and causality in ecosystems. The development and application of modern toxicological assessment approaches, such as computer-assisted sperm-motion analy- ses or image analyses-based histopathology to ecological assessment, are major research activities. Chemical Methods Research The EMSL-CI is investigating cost-effective methods that can help fulfill regulatory requirements. New methods and instruments are being considered that have demonstrated equivalency with traditional tech- nologies. The focus is on safety and waste minimization. When an analytical procedure can be performed with 1 g of material, for example, it is imperative that the analytical laboratory not generate 50 g of toxic material in the analytical process. Complete instrumentation will be developed that will include modu- lar sample collection, assessment, cleanup, concentration, and quality control. The use of robotics and specialized computer processes is of interest to the EMSL-CI. 22 ------- Pathogenic Suite - A Public Health Facility The AWBE]|C contain^ a state-of-the-art facility for the safe study of disease organisms that pose a public health risk in the environment. The pathogenic suite features its own Hepa-filtered air circulation system, media preparation, glassware washing, and sterilization areas. There is a secure, limited access to the facility and a clean room entry, if required. The pathogenic suite provides a research environment for Class 3 pathogens. 23 ------- mmmm m ••••* sss EMAP - Monitoring for Trends The environmental monitoring laboratories of the EPA, in 1990, began an extensive monitoring project that spans their geographies, media, arid specialties: the Environmental Monitoring and Assessment Program (EMAP). It has an ambitious goal —the measurement of current ecologi- cal status, the incorporation of pertinent historical information, and the eventual documentation of trends in the environment of the entire United States. Specialties within EMAP include forestry, arid, and agricultural re- search, water monitoring, and the measurement of various terrestrial ecological parameters. This program needs innovative physical and biological monitoring methods and EPA scientists are rising to the challenges. The program provides opportunities for CRDAs to engage other researchers in this valuable work. 24 ------- j Radiation Monitoring: A Public Service; A National Commitment Monitoring the environment for naturally-occurring and man-made radiation is a responsibility shared by EPA, other federal, state and local agencies, and many industries; Mature technologies exist for radiation monitoring in all phases, but new work is in progress too! New devices are being designed and tested that are capable of detect- ing radioactive material underwater by using innovative scanning equip- ment. Renewable radon generators can provide a steady source of radon in water to be used for laboratory standards and in comparison studies. This is achieved by using an impregnated resin. There is strong EPA interest in the development of smaller, more sensitive, field-portable, and interactive detectors for alpha, beta, and gamma detection. In-situ sensors for radiation in pipe scale is a new area of concern for environmental scientists. The radiation in the iron-steel pipes used in the oil industry must be measured by a remote device. Work on the smaller, remote devices is of great interest. Also, satellite telemetry can provide transmission of monitoring data that is virtually continuous by employing satellite transmitters matched with pressurized ion chambers. This technology has proven successful for monitoring sites for radioactive atmospheric releases. 25 ------- The Nevada Test Site: Monitoring Challenges in Mixed Matrices Since 1951, the DOE and its predecessor agencies have maintained a nuclear weapons test site in the desert about 90 miles north of Las Vegas. This facility, known as the Nevada Test Site (NTS), has been the location of hundreds of nuclear weapons tests over the decades. Early tests were done above ground but, since 1962, all weapons-related tests have been conducted underground. TheEMSL-LV actively monitors the amount of radiation in the water, air, soil, vegetation, and grazing animals within 100 miles of the NTS. Meticulous testing of sites in the sparsely populated areas downwind from NTS monitors the presence of any radioactive isotopes traceable to the test site work. The apparatus in place includes various air samplers that use charcoal filters, particulate filters, and molecular sieves to continuously sample air atstrategiclocations. Radiationlevels in water are monitored by sampling and analyzing water from various monitoring wells near the NTS. Con- taminated soil is monitored by taking samples at specified locations and ------- EitablisfWlg a CRDA with the EPA f -1 The authority to negotiate and sign CRDAs and licensing agreements under the FTTA is delegated to laboratory directors". This decentralization of authority is subject to EPA's requirements for coordination with the Office of theJIeneral Counselandjwith the Grants Administrator of the Office of Administration, who will offer advice on the wording of CRDAs and will maintain official Agency files on all agreements. The first step in establishing a CRDA is to contact the FTTA Coordi- nator, listed on the last page of this booklet. Next, meetings and conver- sations must be held with principal investigators to determine the advan- tages of the cooperative research. Finally, a liaison will be appointed to work with both parties and with a legal review team to assemble the appropriate documents in a timely and legally defensible manner. The laboratories are committed to making the process as simple as possible so that research will not be delayed by unnecessary paperwork. Consistent with the intent of the act, the procedures are streamlined for efficiency but provide adequate legal review to avoid future problems. The Environmental Monitoring Menu Several areas of research are currently active at the various EPA monitoring laboratories. These can be divided into categories by media (soil, water, air) or by technology (chromatography, spectroscopy, geo- chemical). A menu is presented here by media. The technologies fre- quently cover several media, such as high resolution-mass spectrometry for organic compounds in water, soil extracts, or air. 4 Experts are available at the EPA monitoring laboratories to answer questions about these technologies and regarding the first steps to take in establishing a CRDA with the Agency. 28 ------- sending them to an accredited laboratory or by using the latest in field- portable instruments to screen areas for radioactivity. Though many of these radiation technologies are mature, incremental improvements are ongoing, making possible better sensitivity, lower cost, and integrated use of robotics and computerization. The EMSL-LV has been a leader in environmental radiation monitor- ing and radiological emergency response for nearly four decades, with a history of support for the NTS that predates the Agency itself! This commitment continues today with exploration of innovative technologies that will answer the challenges of radiation monitoring tomorrow. Some innovative technologies for radiochemical monitoring that are being investigated at EMSL-LV are: Radon generators that supply renewable, reliable standards for quality assurance in the radiation laboratory. In-situ sensors for the measurement of radiation in pipe scale, a recently identified area of concern to the oil industry. Underwater scanning devices that are able to detect drums con- taining radioactive material that lie on the ocean floor. Continuous monitoring devices that provide constant vigilance. The improvement of current dosimetry devices to detect exposure in a sensitive and timely manner. ------- Monitoring Technologies AIR Particulates Indoor air Microbiological Exhaust fumes Factory emissions Ozone Chlorofluorocarbons On-road vehicle SOFTWARE Expert systems Data validation Geostatistics Error isolation Multivariate outlier identification REMOTE SENSING Photogrammetry Photointerpretation Global positioning systems Geographic information systems .
