Dr. Eric Weuer and Hr. George Baughman attended the fcPA-sponsored Azo Dye
and Pigment Regulatory Workshop in Raleigh, NC, on August 15-17, 1388. They
presented their latest re-search findings ami participated in discussions to
develop a regulatory strategy for azo dyes. In support of this effort, samples
from the influent and the effluent of a municipal treatment plant receiving,
waste from a North Carolina textile mill were analyzed. Thin layer chro^atc-
graphy indicated the presence of approximately 20 dyes 1n the Influent and 3
dyes 1n tha effluent. The dyes in the effluent are most likely acid or direct
dyes. Methodology currently 1s being developed to separate and isolate the
dyes in the effluent sample.

PROJECT DESCRIPTION:
GOAL: To develop computational methods for estimation of fundamental
'reactivity' parameters (rate constants, equilibrium constants, etc.) for
various compounds based on their molecular structures alone.
RATIONALE: A major pnrt.ion of th° pollutant fate program at Athens ERL is the
development of mathematical relationships describing the rate/extent of
individual transformation/transport pathways for pollutants in aquatic or
terrestrial ecosystems. Current models require as inputs certain fundamental
•reactivity' parameters. Algorithms providing for a priori estimation of these
chemical parameters are needed to enable use of process models 1n situations
where measured parameters are not available. Recent advances in computer
technology enable the use of computers to integrate theoretical (qualitative
and quantitative) and heuristic reasoning with appropriate data Lo produce
predictive algorithms of the type needed.
APPROACH: An expert systems shell will be constructed to: (1) discriminate
within the molecular structure primary reactive units versus oertnrbatlve or
nuncontributing units, (2) develop rule? for classifying and .characterizing
reactivity, and (3) develop data to 'calibrate' taith regard i'j reactivity.
PROJEtl STATUS AND ACCOMPLISHMENTS TO DATE:
Two refinements ire being made in SPARC, the ERt-Athens expert system for
predicting chemical reactivity parameters:
1) Since the quality of computational output necessarily reflects the quality
of calibration of parameters in any succussful quantitative ch.emlca! model, a
"self-training" algorithm called TRAIN has been developed for SPARC. The
program takes a set of target model parameters (initial values plus any appro-
priate boundary values) together >."ith a :;t of designated dat.i and provides an
optimized set of model parameters. TRAIN cycles through a Jacobian optimization
procedure, then sets up and executes the specifics of optimization a;, requested

2) A performance validity (PV) program module is being written to assure
thai all computational elements in SPARC are working at optimum by being sub-
jected to a variety of compounds (about 100) that represent different types of
molecular reactivity. The nature of these representative compounds is such
that all types of computation ip the system are checked for evidence of ariy
"rippling" effect that might remain unnoticed in the system. The purpose of
PV is to sustain the validity of program code and performance as the total
system (SPARC) 1s being developed. This will enhance confidence in the system
as algorithms for other chemical reactivity parameters (hydrolysis. Kow, redox,
etc.) are being developed.

PROJECT DESCRIPTION:
GOAL: To develop a modeling technique for evaluating the water quality benefits
provided by wetland ecosystems.
RATIONALE: Wetlands, primarily through actions of microblaI communities,
provide environmental benefits by capturing organic toxicants. This pollution
control function must be evaluated and documented so that the beneficial
effects of wetlands in water quality maintenance can be evaluated against the
economic value of land development.
APPROACH: The microbiological community ecodynamics that create toxicant
dissimilation capacities will be characterized. This will include
Investigation of the effects of geographic and seasonal variables on process
dynamics, the interactions of nutrient and toxicant loadings, and the
load-bearing capacities of wetlands. This Information along wilii other AERL
work in ecological risk analysis will be used to develop a nutrient-organic
toxicant computer model f.hat can be used by technical personnel and
environmental decision maters as an objective tool for rational risk/benefit
evaluations in specific wetland basins.

PROJECT DESCRIPTION:
GOAL: This research will Identify and determine distribution of unlisted
chemicals In Industrial wastewaters. Compounds Identifiable by empirical mass
spectra matching and t^ose eluding identified by this technique will be
included.
RATIONALE: The current 11st of pollutants that are regulated in industrial
waslewaters was established without accurate knowledge of actual occurrence of
chemicals in the wastewaters; hence, some listed compounds may occur-
infrequently and other hazardous or toxic chemicals that are not listed may
occur more frequently than listed ones. Determining the distribution of
unlisted hazardous and toxic chemicals will permit establishment of improved
1isus for regulation.
APPROACH: Computer program: will be developed and applied to search stored
GC/MS data from industrial wastewater samples for nonpriority pollutants; mass
spectra will be compared with library spectra for identification. Compounds
that elude identification by spectra matching will be identified by reanalysis
of samples using multisper.tra I techniques (low res. MS. electron impact MS, low
rov chemical 1oni;ation MS, high res. MS, FTIR spec.). Computerised multi
spectral interpretation approaches will be developed to improve efflcency.

state-of-the-art and Includes a high resolution stage capable of better than
1:50000 resolving power as well as a final collision and quadrupole section
capable of 100 pg detection of certain MS/MS transitions.
A significant decision was made during the quarter to discontinue
processing of 6C/WS lapes from the Office of Uat&r and from Suparfund effec! ive
January 1989. This fisdsior, was made due to the need for extensive and
major modifications to the software for which resources are not available.
Study of the results from the industries processed for the Office of Waler
during the last jear indicated that both GC-peak recognition and quantItatIon
using the software developed in 1977 at ERL-Ather.s were poorer than those
obtained using the dedicated computers of state-of-the-art GC/MS systems. It is
believed that the source of this is the CLEAN algorithm, which is the most
patched, complex, and least understood portion of the coding. 11 is the one
that we understand the least. The mandated change from the INFORM database set
up here in the late 1970s to the FOCUS database itself requires the service of
all of our programmers through the end of the calendar year. We recommend
ruprograrming the tape programs from the start, incorporating the FOCUS database
management system and the most-up-to-date peak recognition and quant Hal ion
algorithms, before processing more tapes. Funds are not available to do this.
It is expected that reprogramnrlng will Introduce a 1-year to 2-year delay in the
overall tape programs if they are reestablished.
As targets for confirmation analytes from the Office of Water tape re-
analyses, the following tentatively identified compounds have been selected from

PROJECT DESCRIPTION:
GOAL: Identify and determine frequency of occurrence of unlisted compounds
that may pose a hazard to human health In potential drinking walur sources with
emphasis on potential groundwater contamination so that the contaminants can be
prioritized for health assessments.
RATIONALE: The 1986 Amendments to the Safe Drinking Water Act require that
lists of Recommended Maximum Contaminant Levels (RMCL) and monitoring
requirements be published January 1, 1988 and every three years following for
previously unregulated contaminants in drinking water that pose a health risk.
Most monitoring programs identify only currently regulated compounds, therefore
reanalysis of monitoring raw data is needed to identify unregulated compounds
as candidates for listing.
APPROACH: Computer programs will be used to search GC/MS raw data from
analysis of grounuwnler and other potential Bw sources for unregulated
compounds. Mass spec.lra will be compared with library spectra for
identification. Compounds that carmot be iotnLified by spectra matching will
be identified by reanaiysis of samples usinn multlspcctral techniques (lew
resolution electron impact MS, high resolution MS, Fourier transform IR
spectrometry, chemical ionizallon MS).

attempt is being nude to equip a mobile laboratory.
Work continues on a spectral library of the ultraviolet-visible spectra of
major minerals found in soils and sediments. Band deconvolution and separation
into separate "peaks" Is being done by using the first, second and third deriva-
tives of the major peals.
Studies of metal interactions with bacteria continue at the University of
Arkansas and the University of Guelph. Single metal ion reaction versus
multiple metal reaction with four bacteria was evaluated at Arkansas for the
metals Ag(I), Cd(II), Cu(II), and La(III). In all cases, both the amount of
metal sorbed and the K.D were lower in the 4-metal treatment than in the single
metal ion 'treatment. The total amount of Ag(I) bound, however, was not greatly
reduced by the presence of Cd(ll), Cu(Ii), and l.a(Ill). There was a
difference in metal sortition by bacterial specie; P. irugirr_oss was the most
efficient binder of metals.
Electron raicro:copy and energy-dispersive analytical x-ray analyses (done
at the University of Guelph) of the metal-treated bacteria indicated that Ag(I)
may actually be precipitated as elemental Ag both in the cell wall arid the

In earlier work at ERL-Athens, the reaction rate for anaerobic biolysis of
para-substituted nitrobenzenes was observed to be slower with increasing chain
length of the substituent. A good correlation could he m«de between reaction
rate and Van der Waals radii. Results of current experiments show that this
correlation does not hold with aliphatic para-substituted anilines. It appears
that two distinct degradation pathways are functioning in this case--the first
being biological attack on the aniline group and the second the biochemical
oxidation of the aliphatic chain. Attempts are being made to Isolate bacteria
that degrade octylanlUne and aniline in spiked natural water. If this
succeeds, kinetic and product studies will bo conducted with pure bacterial
cultures to confirm the observation ihat. two biological pathways were operating
1n the para-substituted aniline degradation.

PROJECT STATUS AND ACCOMPLISHMENTS TO DATE:
The report "Validation Status of Pesticide Leachir-n and GroMo
Transport Model" was provided to OPP. One of the key points of the import was
the development of a model performance index as a quantitative measure of the
predictive capability of a model. The methodology addresses the question of
whether model predictions are within a given factor of the true concentration
values, it appears that this index will be useful 1n surcharging model
capability and for comparing relative performance of one rr.odel versus another.
Results of preliminary testing of PRZM Indicate that the model was not able
to simulate a perfect fit between the observed and predicted residue concentra-
tion profiles for aldicarb, although in several Instances the predictions were
within confidence bounds. For raetolachlor, the model performed relatively much
better.
PRZM was found to be sensitive to both degradation rate coefficients and to
heavy rainfall events. Those observations have implications In regard to
analysis of model components (I.e., hydrology, degradation raJs) and also with
regard to estimation of model parameters arid to calibration techniques.
In regard to analysis of pesticide concentrations in soil profiles, there
were instances in which the capability index indicated that model predictions
differed from true values by a factor of 2 or more, but in most cases FRZM
appeared to be capable of predicting with a factor of 2. These observations
were consistent over four crop/pesticide application years. The large index
values usually were associated with very small observed concentrai. ions. Pesti-
cide movement to deep levels (approaching the water table) was no* observed nor
was 1t predicted by PR7M for either aldicarb or metolachlor. The limited move-
ment did not pcrait an investigation of the deep-zone predictive cspabi'ities of
PRZM. although the fact th^t. PRZM did not predict deep movement 1: consistent
with the data.

PROJECT DESCRIPTION:
GOAL: Characterize key environmental processes that, lead to transformation or
transport of pesticides in soil, sediment, water «r,d related environments;
apply this information lo improve predictive techniques for environmental
exposure.
RATIONALE: Transformation processes such as redox reactions in anoxic
environments (some sediments, subsurface zones), photolysis on soil and plant
surfaces and in the vapor state above application areas, and surption,
especially of irrigable pesticides, are not characterized to the extent
necessary to account, for pesticides loss to the environment. Degradation
products arc not identified for many processes.
APPROACH: Laboratory studies using natural waters, soils, sedirrants, and
reference materials will be conducted to test proposed equations for pesticide
transformation kinetics and sorption equilibria. These studies will provide
rate and equilibrium constants required for exposure predictive models.
Compounds and reaction conditions will be selected to premit generalizations
aJbout changes in molecular structure an* environmental conditions, initially,
photochemical transformations en soil Surfaces artd ^orpliot'i of water soluble
(irrigable) pesticides to soils and sediments will be emphasized.

PROJECT DESCRIPTION:
GOAL: Provide long term, short turnaround, or direct single or multimedia
exposure assessment technology assistance to OPP.
RATIONAL: OPP occasionally needs quick turnaround, customized model
development and application assistance for high priority regulatory actions
mandated under FIFRA. This effort provides a focused, coordinated body of
expertise comprised of ORD and OPP agency personnel! augmented by extramural
specialists to meet this need on demand. It also provides the expertise to
develop needed long term multimedia, site-specific exposure assessment modeling
techniques.
APPROACH: Develop or assemble single and multimedia pesticide exposure
assessment packages from SOA components and apply them to high priority OPP
regulatory problems. Athens ERL also 1s responsible for generating needed
agronomic/management scenarios for non-irrigated crop applications and
reporting requirement to OPP. Close coordination with similar exposure/risk
mode! development activities for OTS and OW are envisioned and required, e.g.
PMN assessments.
PROJECT STATUS AND ACCOMPLISr«NTS TO DATE:
Activities this quarter concentrated on model development. The linked
groimdwater-leaching model, designated ss RUSTIC, is undergoing comprehensive
review and testing -;bela tests ond sensitivity tests). The overall model
includes an enhanced PRZM, a one-dimensional unsaturatcd zone module, and a two-
dimensional saturated zone module. Prusenlly, the model runs on the Agency's
DEC-VAX but is too iarge for operation nn personal computers.
Other activities this quarter concentrated on assisting OPP 1n changing
their runoff modeling from the SWRRB-b;scd approach (an OPP model) to a similar
approach based on Pf.'ZM. This conversion should enable more uniform exposure
assessments by analy2ing runoff, leaching, and ultimately terrestrial problems

PROJECT DESCRIPTION:
GOAL: Develop, refine and extend existing terrestrial and aquatic fate,
transport and effects models to Include hazard Impact, subroutines and data for
environmental risk assessments (RA) for the labeled use nf pesticides. Results
roust be expressed in terms of probability of impact and frequency of occurrence
and duration.
RATIONALE: Proven, operational environmental RA models are needed to evaluate
registration requests for new pesticides and for re-registration and label
changes (e.g. new uses) of existing compounds under H1HKA.
APPROACH: Existing imsaturated/saturated zone soil transport models, proven
runoff-surface water pesticide codes, appropriate ground water codes and
related air transport models will be combined to produce SOA exposure
assessment model framework. These will then be linked with available effects
models to produce defensible RA methodologies tor OPP. As completed, the risk
assessment packages will he tested and evaluated, especially in terms of
probabilities and uncertainties associated with real world problems. Close
coordination will be requires with CERL, RSKERI. ASRL-RTP and the aquatic fate
research at AERL.
PROJECT S1ATUS AND ACCOMPLISHMENTS TO DATE:
A user's manual (7977A) has been developed for a computeriied methodology
to assess potential toxic chemical exposures to terrestrial wildlife. The
Terrestrial Ecosystem Exposure Assessment Model (TEEAM) is a major product of
the Ecological Risk Assessment Research Program.

PROJECT DESCRIPTION:
GOAL: To provide modeling approaches for evaluating exchanges of toxic
chemicals between aquatic organisms and their environment.
RATIONALE: The evaluation and prediction of risk from toxicants must be based
on sound methods for assessing the uptake, distribution, and effects in target
organisms. Testing all chemicals would be impossible and models must be
developed which can use readily available chemical parameters to make
predictions.
APPROACH: Exchange models will be developed to provide estimates of body
burdens of candidate chemicals. Models will be based on thermodynamic
principles and morphometrlc characteristics of organisms as well as talcing into
consideration route of exposure (water, food, or bentMc sediments).
Assessments can then take Into account multiple sources of contaminants and
also be extended to include ecological significance or effects. Physiological
response depends on the chemiral concentration in the organisms rather than
that in the environment and the exchange models will be linked to toxicoklnetic
models to predict effects. Laboratory experiment* will be conducted to test
underlying hypotheses, and ether factors involved will be identified.
PROJECT SI AIMS AND ACCOMPI ISHMENTS TO DATE:
An article (7900A) describing the passive accumulation in fish of organic
chemicals in environmental waters and in contaminated prey was submitted for
publication In the C»nad'>n Journal of Fisheries and Aquatic Sciences. The
work represents a continuing enhancement of the Food and Giil Exchange of Toxic
Subtances (FGtTS) model.
FGETS was presented at two EPA Center for Exposure Assessment Modeling work-

A database working group composed of scientists from ERL-Athens, Computer
Sciences Corporation, and the University of Georgia continued biweekly meetings
this quarter in a project to develop software for a Geographic Information
System for exposure assessment. This software will interface EXAMS and FGETS
with a G1S that will identify species at risk.
In August, Dr. Barber attended a Human Health (Cancer) Risk Assessment Work-
shop sponsored by EPA Region IV and discussed the FGETS model. As a result, Mr.
Ron Landy, a lexicologist in Region IV who attended the meeting, became very
interested in the possibility of applying FGF.TS in some of his work. Assistance

PROJECT DESCRIPTION:
£OAL: Characterize key chemical processes:direct-1nd1rect photolysis,
hydrolysis, redox reactions, and sorption/dssorption and provide addiiicnal
scientific understanding of sediment-water exchange to Improve exposure and
risk assessment models.
RATIONALE: The rolss of Inorganics in pullutanL transformation by photolysis
and the kinetics of redox reactions are inadequately understood for reliable
use in exposure assessment models at the present time. These processes are
known to be environmentally important 1n many cases.
APPROACH: Laboratory studies with natural waters, with sediments arid with
reference materials will be used as the basis for acceptance or rejection of
proposed equations for the kinetics and equilibria of transformation
processes. The laboratory studies will provide rates and equilibrium constants
to fill the equations. Compounds and reaction conditions will be selected to
permit generalizatlons about changes in tnolccular structure and environmental
composition. Photoci-emical studies will emends Ue role of naturally occurring
inorganic species: redox reactions of abiotic systems, relative to blctic
systems, will be studied.

Dr. Eric of ERL-Athens k'eber attended an EPA-sponsored Azo i)./e and Pigment
Regulatory Workshop in Raleigh, NC, on August 15-17, 1988. Weber presented his
latest research findings and participated 1n discussions to develop a regulatory
strategy for azo dyas.
Dr. k'eber and Mr. George Baughman organized and co-chaired a symposium at
the National Meeting of the American Chemical Society in Los Angeles, CA. on
September 25-30, 1988 entitled "Environmental Chemistry of Dyas." Weber
presented a paper on the reduction of Disperse Blue 79 in anaerobic sediments.
Studies on the role of trace metals in photochemical redox processes
continue with work involving iron, copper and manganese. Two types of studies
are being pursued Involving iron. One 1s concerned with the effects of various
environmental variables on the fate of oxidation and/or reduction of Iron in
aqueous solution. The reduction of iron (III) 1n the presence of fulvic acid

The second group of iron studies involves the degradation of several organic
substrates in the presence of iron, hydrogsn peroxide and octanol with sunlight.
The substrates examined were, in order of deoeasing reactivity, p-nitrophenol,
p-cresol. nitrobenzene, and at.ra?ine. Oth^r substrates will be tested using
the same system.
Studies of the reactions of manganese oxides with phenols are continuing.

predicting rates of new chemicais, it is necessary to define what, constitutes a
"chemical class." flnce defined, the infrared spectrum of a compound whose
transformation rite is unknown can be compared to that of the base compound
representing the appropriate chemical class. To define chemical classes, a
four-person committee examined the feasibility of classifying 300 lo 500
chemUals constituting Iwo lists of EPA-regulated compounds. (Classifying a
larger population ot chemicals Initially is impractical.) Abiotic hydrolysis
was the transformation process considered, and the reactive moiety was chosen as
the basis for classification. The co™nittee has determined, at this point, that
the classification process is feaslbU. and will continue its deliberations.

PROJECT DESCRIPTION:
GOAL: Expand data bases for establishing Property Reactivity Correlations
(PRC) and develop quantitative relationships between microbial rate constants
and molecular descriptions.
RATIONALE: Tnere is a need for developing predictive models for fate arid
effects based on SAR/PRC, because resource limitations preclude laboratory
characterization of all chemicals of interest.
APPROACH: Lab studies with natural water samples will be used as a basis for
assessing formulations for lite kinetics of processes describing microbial
transformation of pesticides and other toxic chemicals. Emphasis will be
placed on measurements of blomass associated with transformations. A
homologous series of compounds will be used to examine how systematic changes
in compound structure influence the microbial rate constants. Product analyses
will be used to verify common transformation mechanisms.

not likely to accumulate.
An automated spectrophotometric assay was adapted to measure the kinetics
of cell number increase. The extinction coefficient of cells in river water
was 1.1 x 10E-9 Abs/(cells/ml). The snectrophotomctric assay provides a
measure of Co, the number of cells at zero time, by back extrapolation of the
Nineties. The spectrophotometric assay will supplement the knowr>. assays for
cell number — cell plate (CFU) counts and acridine orange staining followed by
microscopic counting. In some cases the spectrophotometric assay is easier and
generates more complete kinetic curves.
(2) Analytical Characterization of River Water. Standard tests are being
implemented to characterize river water each time a sample is taken. To date 1t
is concluded that one sample of river water has the following properties/compo-
sition: T - 25.8'C; pH 6.9; O.G nrM unknown buffer, pKa 6.4; estimated 3.6 mg/L
humic + fulvic acids (based on UV-VIS spectra of river water and conascrcially
purified humic/fulvic adds); 9SS polar compounds (by LC/UV).
(3) Characterization of Cell Strains in River Water. Cells 1n river water
are being analy?ed for cell number, strain Identity, and strain frequency. The
CFU/plate count is dependent on the lima of incubation of the plates up to 4
days. This variable was eliminated by counting plates after 6 days. Storage of
river water above O'C yielded a 4-fold (4-C) to 8-fold (25'C) increase in CFU/ml
after two days after which cell number was stable for 40 days, whereas storage
at O'C resulted in a 40-fold loss of cells. Strain variability, analyzed by
visual Inspection of agar plates, appeared constant for river water stored at 25
and O'C for 42 days (> 8 strains), but decreased upon storage at 4'C. Thus,sur-
prisingly, the '-sst conditions to maintain river water at or near its original
state appears to b« 2b'C (room temperature) based on these preliminary findings.

tissue had the highest concentration of TCB, and levels increased with Lime.
Concentrations in other tissues were uieie variable and further studies to deter-
mine the three best tissues to monitor are underway. A review of this work was
presented at a workshop on "Food Chain Modeling and Experimental Verification"
at CRL-Ather.s in September. More definitive studies on uptake are proceeding
ana studies in the respirometer on sublothal effects as measured by stamina
under a swimming stress will begin next quarter.
The cooperative agreement with The University of Georgia is proceeding on
schedule. Data :>tructures for databases to support aquatic ecosystem models and
dBASE3 files containing FGETS physiological parameters for various fish species
are being evaluated by the CcoRisk group.
Two manuscripts, "Survival of the Fattest: A Theory for Assessing Acute
Effects of Hydrophobic Chemicals on Populations" and "Deterroinitlon of Effects
of Lipophilic Toxicants on the Dynamics of Daphnia Populations," were submitted
for publication in Environmental Toxicology jnd Chemistry. Development of the
physiologically structured population model for fish, which is analogous to the
Daphnia model described 1n the aforementioned manuscripts, continued.
A qualitative sensitivity analysis of the TOX effects model was conducted
this quarter. Although we have previously hypothesized that much of the dif-
ference in species susceptibilities could he explained largely by spec1es-to-
sperie? variations in lipid content, results of these analyses suuyest that
differences in gill morphometry also may be the basis for as much if not more of
species-to-t-pecies variation in acute toxicity tests. Development of a user
friendly PC interface for TOX was started. This interface will be completed
early next quarter.
To help facilitate user input to TOX, FGETS, and other EcoPisk models, a
units conversion program for the PC ha: been developed. The interactive version
of this program is now complete. Next quarter, a driver program that will allow
its use with specific models will be developed.
In an article in preparation, experimental observations on the bioconcen-
tration of two chlorobenzenes in three plant species arc compared to model
simulations that predict chemical exchange based on fugscity gradients, plant
morphology, and plant proximate composition. Partitioning experiments using
three different extracts of Hydrllla vertlcillala were conducted also to deter-
mine the magnitude of chemical partitioning into nonlipid, structural plant
parts.
OPP has requested assistance 1n generation of appropriate databases for

PROJECT DESCRIPTION:
GOAL: Develop computerized risk assessment system that helps OPTS analysts
conduct various tiers of risk assessments efficiently, including methods for
quantifying uncertainty in risk analyses, and procedures for optimal use of
laboratory data, field studies, and modeling techniques.
RATIONALE: Risk assessment requires a wide variety of data and analysis
techniques to implement the multi-tiered approaches used by OPTS. Efficient
software can help OPTS analysts bring together appropriate data and analysis
techniques in an appropriate structure for each specific risk assessment.
Present exposure and effects models rarely give the estimates of uncertainty
that are required to reduce total uncerta irtty while minimizing implementation
cost.
APPROACH: Existing software will to reviewed including GEMS, ANNIE, and the
IIASA-IRIMS system. Relational data bases will be assembled and prototype risk
assessment modeling sys*oras will be developed incorporating all submodels,
databases and uncertainty analysis techniques. Protocols will be evaluated by
laboratory and tield studies to optimize risk sssossrcent procedures.

A good preliminary selection of Idpes, sample extracts, and report packages
was made and has been received from the Siiperfund Sample Manageinent Center and
various contract laboratories for the pilot study of Tentatively Identified
Compounds (TICs). There were two anticipated problems regarding our ability
to examine the tapes: the first, which was considered to be more serious, was
that the tapes made on HP GC/MS systems might not be readable by either the
VAX or our Superlncos: the second, considered less serious, was whether we might
have trouble reading data from the most recent Incos system, which is now in
use in many contractor laboratories. It now appears that those laboratories
having HP systems are willing to prepare the tapes for us 1n a format that
can be read by both the VAX and our laboratory computer; this avoids the first
problem. The second problem 1s both surprising and serious. We are unable to
read the Incos 5100 data tapes on our older system. Mr. Myron Slephenson of
Region IV also has found that his newest Finnigen SC/MS is unable to reed files
from the older Superlncos systems. He has Just received a 9-track magnetic tap«
unit and is about to evaluate whether lie can use this as a means of transferring
files. It" he 1s able to do so, he will attempt to translate some of our
contractor laboratory tapes for us. The Superfund tapes that can be read have
been given a preliminary screening on the VAX. The HIT and reference databases
are being modified to reflect the new Internal standards, columns, and
conditions.

PROJECT DESCRIPTION:
GOAL: Characterize and identify basic biological processes that lead to the
anaerobic degradation or detoxification of hazardous wastes in contaminated
sites.
RATIONALE: This research is required to produce a reliable approach to the
selection and use of biotreatraent processes in Ihe remediation of contaminated
hazardous waste sites.
APPROACH; Pathways and mechanisms for th« anaerobic degradation of hazardous
organic chemicals will be characterized and identified 1n environmental
samples. Anaerobic consortia capable of growth on these compounds will be
enriched from the environment. The key microorganisms 1n the consortia will be
isolated and identified. Key organisms will be added back to the environemntal
samples to determine whether they enhance degradation of hazardous organic
chemicals.
PROJECT STATUS AND ACCOHPLJSHMtHTS 70 DATE:
Under a cooperative agreement with Or. L1ly Young at New Tork Medical
Center, we have determined the stoichiometry o'. the degradation of p-cresol
under denitrifying, sulfate reducing, acet.-genie and methanogenic conditions.
Using specific metabolic inhibitors, we have been Investigating the relative
importance of different microbial components of the individual enrichment cul-
tures. Results from these studies will be important in deternnning which
organisms are key to the anaerobic bioremediation of hazardous waste site;-.
