W. 35th Street Corvallis, Or. 97330 NATIONAL COASTAL POLLUTION RESEARCH PROGRAM Program Element 1B1025 GENERAL MODIFICATION IN RESEARCH PROGRAM Changing emphasis and recent legislative mandates have resulted in substantial modifications to the Coastal Pollution Research Program, scheduled to become effective July 1, 1973. Ocean Dumping In support of the permit activities regulating ocean dumping required by P.L. 92-500 and 92-532, research will be conducted to study the fate of particulates dumped from barges, and to develop methods for the assessment of environmental conditions at the dumping site. Funds anticipated will be for extramural projects closely associated with our in-house projects. Estuarine Modeling The program's in-house and extramural estuarine modeling work—the only such research effort in the Agency—is to be terminated. This effort, which has enjoyed modest support for several years and produced a number of well received reports, will carry to completion several projects now underway. An Associate Laboratory of the National Environmental Research Center • Corvallis 200 S.W. 35th Street, Corvallis, Or. 97330 ------- Dr. Harleman at MIT will continue to develop mathematical models for predicting pollutant distributions in stratified estuaries. Dr.Bella's work at Oregon State University on tidal flats is close to completion. The Puget Sound modeling work recently initiated by Dr. Winter at University of Washington will be continued under a different category. Because of this important program decision, we would discourage recipients of this newsletter from submitting research proposals for grant and contract funds on the subject of estuarine modeling. Not all estuarine research is to be terminated, however. A major part of our research effort continues to focus on the development of a scientifically sound basis for criteria used to regulate the discharge of treated wastes and barge dumping in estuarine waters. The recent EPA policy designed to preserve wetlands will undoubtedly add to the emphasis for estuarine water quality research. Beneficial Uses and Oil Pollution Terminated Other projects terminated were "Beneficial Marine Uses by Controlled Introduction of Pollutants" and "Scientific Criteria for Oil Discharges into Marine Environment." This latter project represented only studies on the fate of oil. These programs had been started in 1972 and were active only in the planning stages. However, any overtures we may have implied in prior correspondence regarding the possibility of future funding for extramural grants will have to be retracted, at least temporarily. ------- I. INTRAMURAL ACTIVITIES A. New York Bight Work continues on the New York Bight study. The third benthic survey of the New York Bight experimental sewage sludge dump site was conducted in May. Identification to the species level of specimens collected during the second cruise is nearly completed. The data are being prepared for computer analyses of the spatial-temporal distribution, fauna! homogenity and species diversity of the benthic assemblage. Relationships between biotic and abiotic characteristics of the water column and sediments will be examined as part of a baseline assessment of pre-dump environmental conditions. Two current meter stations were established on the periphery of the study area in late May. Retrieval is scheduled for late July-early August. One sediment trap station was also established in May and its recovery will be coincident with that of the current meters. A number of New York area sewage treatment plant sludges have been analyzed (a) to aid in choosing a sludge having little or no industrial input (b) to establish those sludges having nuclides suitable for a set of integral constituent tracers. The results of analyses carried out by computer-coupled, automated, neutron activation analysis at Corvallis, by atomic absorption by CLS at Corvallis, and by atomic absorption (on monthly composited samples) by the New York STP operators have been tabulated and compared. A scientific report giving details of automated computer- coupled activation analysis and of results to date is in preparation. Preliminary conclusions are as follows: ------- 1. Given that the samples used at New York and at Corvallis are not identical it is clear that all three groups are analyzing essentially the same materials and agreement is good. 2. The agreement between CLS and NCPRP at Corvallis, where the same metals are estimated, 1s good. 3. Separate analyses by NCPRP on sediments from the proposed experimental site (for the period to date) show that several nuclides found in the sludges can be used for constituent tracer experiments since they are effectively absent or very low in the sediments examined. Some others, notably manganese, would not be so useable. It 1s intended to follow both the sludges and the sediments over at least one year before making a decision on a specific plant to ensure long-term differentiation. The neutron activation samples can be as small as one mg or less, if weighable and handleable, which would allow tracing the sludges for reasonable distances from the dump site. The following research activities were carried out as part of a continuing program to determine background levels, input sources, rates of Input, and fates of persistent organlcs in the marine evi ronment. B. Southern California Bight and Puget Sound Two cruises were made with grantee, S. Pavlou. The first cruise, off Los Angeles in the southern California Bight, involved collection and some onboard analyses of sediment, whole water, filtered particulate ------- matter, zooplankton, and surface film samples taken from an area near the White's Point outfall. Initial results indicate copious quantities of chlorinated hydrocarbons are present in sediment taken from the area. DDT and its metabolites were detected in each type of sample collected. Surface films were shown to contain a higher concentration of these materials when compared to ambient water. Complete analysis of all samples is expected in the near future. The second cruise was made in Elliott Bay near Seattle. Sediment, surface film, and water samples were collected in an effort to complete the sampling program to determine distribution patterns of chlorinated hydrocarbons in this area. Analysis of these samples will be completed in the near future. Analyses of samples collected from other parts of Puget Sound on previous cruises are near completion. 6C/MS work will be required as part of the analyses. C. Los Angeles River Runoff Analyses of Los Angeles River runoff samples taken by SCCWRP personnel were initiated and are near completion. These analyses represent an inter-calibration effort involving three laboratories, as well as verification of chlorinated hydrocarbons present using the GC/MS. 0. PCB Decay Studies Laboratory studies to determine rates of decay of PCB's in sewage sludge and sediments are continuing. E. Biological Assessment In support of the Ocean Dumping Permit Program, we are participating in the design of biological sampling techniques and bioassays for sludge and industrial wastes. ------- F. Coastal Circulation Modeling The modeling of coastal circulation and pollutant flushing being performed under an Interagency Agreement with the U.S. Navy is proceeding on schedule. Some computer production runs were recently carried out at Berkeley and writing of the final documenting report and users guide was initiated. Final verification of the model will be accomplished using existing shoreside tidal data and historical records of currents. In June, tide recorders were placed up to 80 miles offshore in depths from 15 to 62 fathoms in the New York Bight area. We hope to recover the recorders and begin processing the data in late July. Considerable interest has been expressed by various federal activities in our methods and results, as well as by private engineering companies. Some results were presented at the Salt Lake City meeting of the American Society of Limnology and Oceanography in June. II. EXTRAMURAL RESEARCH A. PCB Decay Principal Investigator Phillips, Hopkins Marine Laboratory, is continuing to analyze stationary preparations for decay of chlorinated hydrocarbons in marine systems. Studies of the rate of decay of DDT as a function of many variables, e.g., temperature, pH, etc., are in progress. B. PCB Input to Los Angeles Bight Principal Investigator Young, Southern California Coastal Water Research Project (SCCWRP), has initiated the aerial fallout portion of the grant. The runoff, advection, and sewage input segments of ------- the grant are approximately 40 percent complete. The second of four storms of the runoff program was sampled and analysis was initiated. The first of two planned samplings of ocean current inputs was accomplished. Effluent of one of two selected sewage treatment plants was sampled. No analysis of these samples has been attempted to date. C. Phytoplankton Responses to PCB Principal Investigator Pavlou, University of Washington, is continuing to analyze samples of phytoplankton and zooplankton collected on cruises in Puget Sound and the Los Angeles Bight. Chemostat studies of perferential inhibition of persistent organics on phytoplankton and zooplankton are continuing. D. Floatables Concerning the significance and control of wastewater floatables in coastal waters, progress on our grant with Cal Tech has been rather slow because of changes in research personnel fostered by the administrative delays in obtaining second year funding. The second quarterly progress report, however, confirms the presence of chlorinated hydrocarbons DDT and DDE in surface slick and non-slick samples. Dr. Selleck, the Principal Investigator, termed this a rather suprising find but a very promising one in terms of the study objective; i.e., the determination of a method of identifying polluted sea slicks. Field studies have been scheduled for early July, and the successful completion of this phase should lead to a timely completion of this grant. ------- E. Marine Predation of Enteric Organisms Dr. Ralph Mitchell, Harvard University, is continuing his investigation of the destruction of enteric bacteria, viruses, and algae by marine predatory microorganisms. He has shown that the rate of predation is affected by additional organic matter and by both biogenic and non-biogenic colloids in the water. F. Marine Biological Assessment of Pollution Stress Southern California Coastal Water Research Project Researchers at SCCWRP are analyzing data from 2700 biological samples, collected from 1914 to 1973, in order to document historic trends in biological conditions at wastewater discharge sites in the Southern California Bight. SCCWRP is also examining the relation between pollution and the incidence of fish and invertebrate diseases. G. Oxygen Uptake of Sediments in Puget Sound A final report has been received from Dr. Mario Pamatmat, University of Washington, on organic accumulation measurements through oxygen uptake, chemical and respiratory, and on methodology development. The report is being reviewed. H. Heavy Metal Distribution in Southeast Coastal Systems An annual report has been received from Skidaway Institute of Marine Sciences, Dr. Herbert Windom, Principal Investigator, summarizing the field work during the first year of a proposed three-year project. The descriptive material covers Southeast coastal inputs of heavy metals and their transport and interaction with coastal currents, biota, particulate material and sediments. Copies of this report are available for those concerned with the specific information. ------- I. Fiord Modeling Our grant on fiord circulation and biological modeling with the University of Washington has been delayed due to confusion in initiating it, but progress has been made in several areas. A new approximate similarity analysis first order solution has been developed which extends the usefulness of the method. Applications of the method have been made in Hood Canal, and the Central Basin of Puget Sound and to Knight Inlet. A paper describing the work so far is in preparation as is a computer deck and preliminary users' guide. III. TECHNICAL ASSISTANCE Technical assistance responses in the past quarter are up significantly from previous quarters and included the following: A. Participation in Operation Quicksilver This undertaking was, in essence, a four day field study with the objective of determining background conditions at the City of Philadelphia's assigned interim dumping site for sludge. The site is located approximately 50 miles off Cape May, New Jersey, and is under the jurisdiction of Region III. Seven sediment trap stations were established in and around the site with recovery scheduled in early August. Temperature, salinity, dissolved oxygen, and current profiles were attempted during this cruise in spite of adverse weather conditions. ------- B. Barge Model Several inquiries have been received relative to the grant-developed math model for the prediction of dispersion of barged waste materials. These requests have been handled individually with selected computer predictions provided when requested. To date, responses have been made to: Region IX - Surveillance and Analysis Division Region II - Surveillance and Analysis Division NOAA - Mi ami, F1ori da COE - Math Hydraulic Section, Vicksburg, MS Region III - Surveillance and Analysis Division Requests for information have also been received from the Argonne National Laboratory and Mount Auburn Research Associates. C. Lake Superior The Agency's enforcement action against the Reserve Mining Company has continued to utilize a sizable percentage of the technical assistance time allotment. The major time expenditures in the last quarter have been in completing statistical analyses of data, report preparation, depositions, and planning functions relative to the recently-discovered asbestos content of domestic water supplies in the Duluth area. Expenditures of time are expected to continue through the trial phases, but it is anticipated that the total effort will be somewhat reduced in ensuing quarters. D. Ocean Dumping Legislation Staff personnel have responded to several requests from Headquarters and Regional Offices relative to the new Ocean Dumping Legislation. Work is now in progress on a methods manual for chemical determination ------- on seawater and marine sediments. This work assignment resulted from a request to the Office of Water Programs by Surveillance and Analysis personnel from several Regions. Completion of this project is expected by September 1, 1973. E. Lake Michigan Dr. Swartz met with representatives of Region V and helped prepare an outline of the data handling and evaluation report for the Lake Michigan Cooling Water Studies Panel. IV.

W. 35th Street Corvallis, Or. 97330 EUTROPHICATION RESEARCH HIGHLIGHTS Shaqawa Lake Demonstration Project April 1973 was the starting date for a full-scale lake restoration demonstration project on Shagawa Lake at Ely, Minnesota. On that date the advanced wastewater treatment plant began full flow operation for phosphorus removal from wastewater entering the lake. The plant is now removing in excess of 99 percent of the total phosphorus entering the plant or about 80 percent of the total phosphorus entering the lake. An integral part of the project is to test and refine conceptual and mathematical models for explaining and predicting lake recovery following the phosphorus removal. Since only one critical nutrient (phosphorus) will be reduced to low levels, the project offers an ideal opportunity to test such predictive models. A mathematical model has been written which relates algal growth to solar radiation and to the concentration of nitrogen and phosphorus in the lake. Simulation runs have demonstrated a reasonable fit of model outputs to observed algal biomass and nutrient concentrations. They have demonstrated, as one of the major forcing functions, the extreme sensitivity to the rate of supply of critical nutrients either from the tributary sources or from the sediments. An Associate Laboratory ot the National Environmental Research Center • Corvallis 200 S.W. 35th Street, Corvallis, Or. 97330 ------- Diamond Lake Nutrient Diversion Study The third year of the study to evaluate the effect of wastewater diversion on the trophic status of Diamond Lake began in May. This south-central Oregon mountain lake provides one of the state's most productive trout fisheries; it is hoped that the diversion of all domestic wastes away from the lake will result in a maintenance of the delicate trophic balance necessary for both successful sport fishing and aesthetic acceptability. Nutrient Inactivation Research Preliminary laboratory screening of a number of candidate inactivants has been completed with respect to (1) phosphorus removal capacity, (2) detrimental effects on biota, and (3) long-term stability of inactivated phosphorus complexes. Aluminum, zirconium, and lanthanum, as well as some by-products of rare-earth materials, have to date performed most satisfactorily. Preparations are being made for pilot-scale field testing on two one-acre ponds near Corvallis. Application of Algal Assays The "Algal Assay Procedure: Bottle Test," published in August, 1971, is being used more and more as a tool for solving and understanding eutrophication problems. These uses include (1) the assessment of a receiving water to determine its nutrient status and sensitivity to change, (2) the evaluation of materials and products to determine their potential effects on algal growth in receiving waters, and ~ (3) the assessment of effects of changes in waste treatment processes on receiving waters. Just recently it was used to determine the effect of smelter waste, high in zinc content, upon the growth of algae in the Spokane River system. The dissolved zinc, which averages 112yg/l in the Spokane River from Post Falls, Idaho to Riverside State Park, 2 ------- Washington masks the effects of phosphorus loadings, up to 200yg/l, from the City of Spokane's sewage treatment plant upon the growth of algae. The test showed that, if the discharge of smelter waste were discontinued, it is likely that nuisance algal growths would occur in the river downstream from the City of Spokane. North American Project The North American Project is part of an international cooperative research program being coordinated by the Organization for Economic Cooperation and Development (OECD; an independent international organization). The program is directed toward the achievement of comparability of data on nutrient budgets, chemical balances, and biological productivity in water bodies. The major goal of the North American Project, which includes both the United States and Canada, is to determine the degree of correlation between nutrient loading and trophic state of a body of water. Sixteen lakes, reservoirs, and estuaries, representing a wide range of trophic conditions, have tentatively been selected as study sites for the United States portion of the Project. A variety of appropriate water bodies will also be studied in Canada. The National Eutrophication Research Program will assist in providing support for the investigations on a number of the United States waters, and in addition will directly carry out the studies on Waldo Lake, Oregon, one of the designated United States lakes. Lake Tunis Pollution Study Thomas E. Maloney, Chief, NERP, is EPA Project Officer for a three-year, $250,000 water pollution study at Lake Tunis, Tunisia, being supported by the U.S. Special Foreign Currencies Program. This very large and 3 ------- shallow lake receives large quantities of sewage from Tunis and other cities and has become excessively eutrophic. The current study, which is a cooperative program between the United States and the Tunisian government, is designed to define the eutrophication problems of Lake Tunis, to evaluate the potential benefits of sewage diversion, and to estimate the rate and extent of recovery of the lake following diversion.

The table on the following page summarizes, state by state, the number of lakes, number of stream sampling sites, and the initiation date for stream sampling by the National Guard of each state. In 1972, the National Environmental Research Center-Las Vegas (NERC-Las Vegas) staff completed lake sampling for all of the lakes in the first ten states listed in the table. The stream and effluent sampling 1n those same ten states, however, was scheduled to continue for 12 months and therefore will not be completed until this summer and fall. As the sampling is completed in each of the ten states, the data will be compiled and evaluated for each lake and its associated streams and waste effluents. This year's lake sampling by NERC-Las Vegas involved only the last seventeen states listed in the table and began in early March in Florida. Following the Florida start, the field staff sampled their way through the other sixteen listed states in the southeast, east and midwest. The initial round of 1973 sampling included approximately 250 lakes and 970 lake sampling sites from which 3,892 samples were collected and analyzed by the NERC-Las Vegas staff. Each of the 250 lakes will be sampled twice more by the end of 1973. Pacific Northwest Environmental Research Laboratory 200 S.

During the last eleven months of FY 73, the lab received 14,686 samples and performed a total of 98,148 analyses for NESP. In June, CLS was being deluged at the rate of more than 3,000 samples per month. PRELIMINARY RESULTS Lake Characterization After spending most of the first year with the tasks of planning and initiating sampling programs, the Survey is now beginning to evaluate the data. For example, preliminary results indicate the following distribution by trophic condition for the lakes which were sampled last year: oligotrophic (13), mesotrophic (25), meso-eutrophic (15), eutrophic (139), and hypereutrophic (50). The cited data do not represent a random sampling of lakes in the ten states because the majority of the surveyed lakes receive sewage treatment plant effluents. Algal Assay Algal assay results to date for last year's lake sampling are indicating about 50 percent phosphorus-limited, 36 percent nitrogen- limited, and the remainder limited by some other nutrient. These percentages may shift somewhat as the data are finalized. The productivity range of the surveyed lakes, as measured by the growth response of Selanastrum capricornutum, has been tremendous. After 14 days growth at 24°C with continuous lighting, samples from 3 ------- the most oligotrophic lakes yielded less than 0.1 mg dry cell weight per liter, whereas the most productive water body yielded 248.2 mg dry cell weight per liter of sample. Land Use Versus Nutrient Runoff A portion of the National Eutrophication Survey involves an investigation of the relationships between general land use practices and nutrient runoff. The ultimate objective is to devise a low-cost, accurate method of estimating nutrient loadings to lakes through development of nutrient runoff coefficients based primarily on land use types and, secondarily, on climatic and geographical characteristics. The method should significantly facilitate the ability to predict the change in nutrient loading to a lake following the alteration of basic land use patterns within the lake drainage basin. Only selected lakes will be included in the land use-nutrient runoff study. Selections are based on the significance of surface runoff in each drainage area, the desirability of encompassing a variety of geographical and climatic areas, and the availability of good topographic maps and usable aerial imagery or recent land use studies. In the 27 states listed In the above table, 103 of the 485 NESP study lakes were chosen for land use analysis, and work is currently in progress to acquire necessary resource materials and to delineate and measure drainage and land use areas. Preliminary results for 128 sub-drainage areas demonstrate a significant relationship between land use type and the concentration of nitrogen and phosphorus occurring in the stream receiving the drainage. For example, in forested watersheds the median total phosphorus concentration in the receiving stream was 0.01 mg/1 whereas in streams draining agricultural areas the median total phosphorus concentration was 0.1 mg/1. As would be predicted, total nitrogen concentration in streams draining various land use types was much higher due to the solubility of inorganic nitrogen 4 ------- species in water. Preliminary results for 128 sub-drainage areas indicate that the median total nitrogen concentration in streams draining forested watersheds was 0.52 mg/1 whereas the median total nitrogen concentration from watersheds used for agricultural purposes was 3.49 mg/1. When flow data are available for each drainage area, nutrient loadings will be calculated for unit areas of the different land use types.

Characteristics of a large mechanical draft unit and powered spray modules will be tested. Groups involved include Florida Power and Light, Environmental Systems Corporation of Knoxville, Tennessee, and EPA's Meteorology and Systems Control Divisions at Research Triangle Park, North Carolina, as well as the National Ecological Research Laboratory and Thermal Pollution Research Program at Corvallis. Closing the Loop in Power Plants Participants at the National Conference on Complete Water use, Washington, D.C. in April, 1973, came away optimistic. Concensus was that we are closer than we thought in achieving the objective of zero aqueous waste discharge. EPA remains interested in cooperative demonstration projects with industry to achieve this goal. Modeling Aquatic Thermal Pollution NTPRP researchers have been active recently in our continuing effort to provide a sound technical base in the area of predicting the transport and behavior of heated water discharges. 2 ------- A sequel to Shirazi and Davis, "Workbook on Thermal Plume Prediction, Volume I - Submerged Discharges" (EPA-R2-72-005a) is well on its way to completion. Using a similar nomograph-type format, Volume II, dealing with surface discharges is planned for release in January, 1974. Drawing on analytical techniques and available field and laboratory data, this report will provide the non-expert with predictive capability. During the preparation of the report, Dr. Shirazi conducted an exhaustive search of the literature for data on surface discharges of heated water and presented a statistical analysis of these data in the form of correlations. This analysis is presented in PNERL Working Paper No. 4, "A Critical Review of Laboratory and Some Field Experimental Data on Surface Jet Discharge of Heated Water." This Working Paper was not intended to provide predictive techniques, but rather was developed to present the various data sets in a unified manner for comparison of important parameters. Experiments were conducted in PNERL's hydraulics laboratory by Winiarski and Chasse to investigate the behavior of heated jets discharged into shallow water. The results of their investigation will be presented in an EPA research report (in press). Cornell University scientists, under the direction of Dr. Wilfried Brutsaert, conducted research on the exchange of heat and water vapor between a water surface and the atmosphere. Supported by EPA Grant No. 16130 DIP, this work was directed primarily towards the problem of predicting evaporation from lakes. The final report, "Heat and Vapor Exchange Between Water Surface and Atmosphere" (EPA-R2-73-259) concludes that: "The semi-empirical turbulent diffusion model with Reynolds' analogy provides a method for the prediction of heat and water vapor transfer from a water surface which should be adequate for engineering calculations." 3 ------- Dr. Brutsaert concludes that for time periods of one week or more, evaporation equations of the following form are applicable. E » bU2 (e0 - ea) where, E = Evaporation from water surface b = Mass transfer coefficient U2 = Wind speed at elevation Z eQ = Vapor pressure at water surface ea = Vapor pressure in air unaffected by water body a The mass transfer coefficient, b, is related to the surface area of the water body in an exponential fashion. Thus, the research conducted by Cornell University confirms the suitability of the semi-empirical evaporation equations; however, the use of such equations for short time periods is not verified. Power Plant Effluent Control Technology Work is continuing on characterizing power plant effluents and developing technology for control of such effluents. Data are being gathered on all streams, but primarily on cooling tower blowdown and SO2 scrubber effluents. Chlorine minimization in blowdown has been emphasized through efforts in developing a mathematical model to describe chlorine levels at any time during cooling tower chlorination cycles. This capability is expected to be extremely useful for continued yet judicious use of chlorine for condenser treatment. It provides the basic predictive "tool" for devising chlorination controls and operating programs which will alleviate the problem of chlorine in blowdown effluent. 4 ------- The demonstration project with Eugene Water and Electric Board on warm water use in agriculture was concluded on May 31, 1972. The final report, currently being compiled, attempts to quantify benefits and potential shortcomings of using warm water for irrigation, frost protection, and underground soil heating. Underground soil heating exhibited the most promising potential benefits from warm water usage. A contract was recently completed by WAPORA, Inc. on cooling tower blowdown state-of-the-art. The project report, currently in review process, covers current practices of handling and treating this waste stream. 5 ------- NEW GRANTS AND CONTRACTS Wapora, Inc., "A Technical and Economic Evaluation of Cooling Tower Blowdown Control Techniques," Contract No. 68-03-0233. This contract documents the currently available blowdown control techniques which can apply to large scale cooling systems (>500 cfs recirculating rates). The contract's goal is to prepare a report that can be used by representatives of industry and regulatory agencies to readily compare the technical aspects, economic considerations, and environmental implications of the various blowdown control methods. Environmental Systems Corporation, "A Comprehensive Drift and Sea Salt Ambient Measurement Program for Evaporative Cooling Devices at Turkey Point," Contract No. 68-02-1365. This project will measure and characterize the amount of salt water drift emitted by both a mechanical draft cooling tower and a spray module. The drift transport will be monitored and comparisons will be made with measured natural ambient deposition levels. 6 ------- NEW EPA PUBLICATIONS 1.

While a later study by WAPORA for Effluent Guidelines will develop additional survey information and projections regarding future waste control technology, the presently available compilation contains valuable data on the industry operations, waste loads developed, external treatment means and accomplishments and in- plant control practices. The report is rewarding and worthwhile reading for those in the industry environmental control field, and it is also excellent educational material on the industry for state agency representatives, environmental control groups, student instruction and lay individuals having a scientific background and a wish to understand industry processes and waste treatment technology. (Contact Ralph Scott for additional information at 503-752-4211, ext. 336.) PULP & PAPER MILL SLUDGE UTILIZATION AND DISPOSAL This cooperative project between Crown-Zellerbach and EPA was conducted at Camas, Washington. The disposal of sludges from the industry is a growing problem as additional primary and secondary treatment facilities become operational. The project examined disposal of primary sludge from the Camas mill by (1) incineration in an air entrained dryer-incinerator, (2) burning in log-fuel boilers, (3) incorporation into soil as an amendment, and (4) hydromulching for soil stabilization. The report contains some interesting operational data and cost information concerning disposal by these several means as applied to this mill. The use of sludge as an additive to agricultural soils developed some worthwhile increases in crop yields as measured by the extensive replicate test crop experiments conducted. Disposal by this means appears to have real merit and also is a conservation measure of higher value than sludge lagooning or land fill disposal. (Contact Kirk Willard for additional information at 503-752-4211, ext. 337.) 3 ------- BY PRODUCT RECOVERY FROM SULFITE CONDENSATES The condensates from evaporation and recovery of sulfite cooking liquors contain a significant portion of the total BOD load discharged from the mill. This fraction consisting of acetic acid, methyl alcohol and furfural as principle BOD materials, is volatized from the liquor. An Institute of Paper Chemistry - EPA project, supported by a number of sulfite mills, has just been concluded with the project report to issue in the near future. Employing steam stripping and activated carbon treatment of condensates it appears that satisfactory treated water can be produced for recycle to mill processes while the value of recovered sulfur dioxide, methyl alcohol, furfural and ethyl acetate may well support the installation and operations costs. This is a pilot project which must necessarily operate on a commercial scale to develop dependable data. (Contact Ralph Scott for additional information at 503-752-4211, ext. 336.) CONTINUOUS IN-PLANT HOT-GAS BLANCHING OF VEGETABLES An experimental hot-gas blancher was operated in two food processing plants using green beans, corn-on-cob, beets, spinach, and green peas. A side stream of commercially prepared vegetables was hot- gas blanched and returned to the production line. Electrical, gas, and steam flow meters were used with the hot-gas blancher to obtain data for operational cost estimates. Wastewater samples were collected from the commercial blancher and the hot-gas blancher for each commodity studied; these were measured for volume and analyzed for BOD, COD, SS, and pH. Comparisons were made of reductions in wastewater volume, BOD, COD, and SS when steam or hot-water blanching were replaced by hot-gas blanching. For beans, spinach, and peas these reductions were greater than 99 percent. 4 ------- Samples of raw arid preserved vegetables were analyzed for vitamin and mineral content. No significant difference in overall nutrient retention was found among hot-gas, steam, and hot-water blanching, and no difference in overall quality was observed. Operational costs were higher for hot-gas blanching than for steam or hot-water blanching for all vegetables studied except for green beans which were slightly lower. (Contact Harold Thompson for additional information at 503-752-4211, ext. 306.) TREATMENT OF DISTILLERY WASTEWATER The American Distilling Co. at Pekin, Illinois, has demonstrated successful full scale treatment of distillery wastewater with activated sludge. Bio-Disc (rotating biological contactor) treatment was successful only after design loadings were reduced by about 70 percent. The Bio-Disc also required an aerated equalization basin and cooling tower pre-treatment to obtain over 90 percent organic removal at a loading of 320 lbs of BOD^ per day (7 lbs BOD^ per 1,000 sq. ft. of disc surface per day). Comparable removal was achieved with activated sludge at a loading of 1800 lbs of B0D5 per day (44 lbs BOD^ per 1,000 cu. ft. per day), and equalization and cooling of influent did not appear to affect efficiency. Nitrogen and phosphorus addition was provided to insure a 100:5:1 ratio of BOD^.-N.-P in the influent to both treatment units. Comparative capital costs are tentative at present, but it appears the activated sludge plant cost would be $530,000 per million gallons of treatment capacity and the Bio- Disc would be $4,230,000. This project was an EPA demonstration grant, and a final report is being completed.

Twenty-seven papers were given during the 2^ day conference on many aspects of inplant process changes to reduce waste loads and new methods for the treatment of plant processing wastes. A report on the conference proceedings is being prepared by Cornell University and will be published as a Federal Report. This Proceedings should be available shortly. As with previous conferences, the National Canners Association was a co-sponsor and active participant in the planning and conduct of the program. The Fifth National Symposium on Food Processing Wastes will be held at Monterey, California, April 16-19, 1974. The meeting next year will be co-sponsored by the National Canners Association and the Canners League of California together with EPA (additional information is available from Jim Boydston, 503 752-4211, extension 313).

W. 35th Street Corvallis, Or. 97330 August 24, 1973 Automated, Computer-Controlled, Chemical Analytical System Now Operational at PNERL Introduction The Consolidated Laboratory Services (CLS) provides routine chemical analytical services to the five research and monitoring programs at the Pacific Northwest Environmental Research Laboratory (National Coastal Pollution Research Program, National Eutrophication Research Program, National Eutrophication Survey Program, National Thermal Pollution Research Program and the National Waste Treatment Research Program). To accommodate a tremendous increase in water quality analysis as part of the National Eutrophication Survey, an automated, computer-controlled, chemical analytical system was designed and incorporated into the existing Sample Handling and Verification System (SHAVES) at the Pacific Northwest Environmental Research Laboratory. Previously SHAVES primarily served as a sample processing and data handling system for nonautomated analyses and automated analyses were inputted through the key punching of data on cards. An Associate Laboratory ot the National Environmental Research Center • Corvallis 200 S.W. 35th Street, Corvallis, Or. 97330 ------- 2 System Requirements With the projected impact of samples as a result of activities on the National Eutrophication Survey Program, CLS began implementing the marriage of an automated analytical system with "SHAVES" and the computer. The system required the attributes of sample identification from receipt of sample in the laboratory to the final result; it needed the capability to analyze levels from those barely detectable to 50,000 times the detection limit. The system would require a suitable quality control program and the ability to analyze 200 samples per day for six constituents (ammonia nitrogen, nitrite and nitrate nitrogen, Kjeldahl nitrogen, orthophosphate phosphorus and total phosphate phosphorus). The system needed to be capable of integrating with SHAVES and designed to include sample input, verification, intra-sample comparison, analytical quality control checks and output in "ST0RET" compatible form. ST0RET is an EPA water quality data storage system. System Operation What does the program do? As indicated by the attached flow chart, the process starts with the sample arriving in the CLS area from project leaders. The sample is coded with an identifier (a seven digit code number) and scheduled for analysis. In the automated analysis section scheduling is done by computer program. ------- 3 At the start of the day the analyst queries the computer for a run list. Using the run list the analyst (or a technician assigned to the analyst) will arrange the samples and will start preparing the samples in the order arranged by the computer program. Each run list consists of a series of standards and a set of samples with appropriate designated replicates followed by a second set of standards. The output of the automated analyses including sample identification is digitized onto punched paper tape. The paper tapes are entered into a computer for data reduction. The computer reduces the peak height output of the automated analyses into concentration values. When the peak height is provided from a sample, the computer determines whether it falls within the bounds of the standards run before and after the sample. When the peak height is determined to be within limits, it is then compared to standards and a computation is made to assign a concentration value to the sample. If the sample peak is beyond the limits of the standards, it is immediately rescheduled to be rerun. Any sample that is out-of-limits may have a detrimental effect on the following sample (washout characteristics); thus, an assumption is made that the next two samples following an out-of-limits sample will be scheduled for a rerun. The out-of-limits sample will be scheduled for a rerun after dilution (5x, lOx, 20x, etc.) and the two samples following will be rescheduled for a rerun with no dilution. ------- 4 The output of the computed value is then merged into a system of analytical quality control (AQC) checks based on replicates, standards and intrasample comparison routines. When the data from the sample makes it through all the checks, the "o.k." is given to place the sample on the "throwout list." The analyst receives the data from the computer and identifies the analyses which may have AQC problems. The analyst attempts to determine the cause of the AQC problem and if necessary reschedules the analyses. When the AQC problem is solved, a valid result is reported and the sample is placed on the "throwout list." The system was put on-line in September of 1972 and by October, 1972 was operational with a rate of 80 samples per day. In January, 1973 "bugs" were worked out and a sample rate of 200/day was accomplished. A turnaround time of 24 hours is being achieved on high priority samples. A normal turnaround time of one week is now the rule. An exception in turnaround is the accumulation of a critical mass of samples for a production run. The system is maintained by 4 chemists, 1 technician and 9 part-time students and is currently operating on a 16 hour day. With a recent total staff increase of two man days/week, the production has been increased from 4,500 analyses/month in May, 1972 to 19,500 analyses/month in March, 1973. ------- 5 Additional Information The details of SHAVES are found in the article entitled "Management System for an Analytical Chemical Laboratory," and the details of the data capture system are the subject of a paper in preparation as given below. 1.
