Executive Summary
Ambient toxicity testing, as a water quality assessment tool, complements chemical monitoring by allowing
observation of the effects of multiple contaminants or contaminant sources on test organisms. Although
biosurveys provide similar information, aquatic community impairment resulting from conventional
pollutants or habitat degradation may mask the effects of toxicants. Laboratory toxicity testing also offers
the ability to observe reproductive or teratogenic effects of contaminants that may not be apparent from a
community-level biosurvey.
The Region 6 State/EPA Ambient Toxicity Monitoring Program was established in 1990 to encourage States
to integrate ambient toxicity testing into water quality assessments, to encourage States to acquire testing
capabilities, to assess potential toxicity in Region 6 waterbodies, and to evaluate the effectiveness of
implemented toxicity control measures. Regional staff encourage State and local agencies to participate in
the program by collecting samples at routine monitoring sites. Samples are analyzed in the Region 6
Houston Laboratory using standard tests. Lab personnel forward results to the Region 6 Environmental
Services Division and the collecting agency. Currently, over 1,050 tests have been conducted on samples
collected from 144 stations.
Regional staff recommend quarterly collection of water samples and biannual collection of sediment for a
minimum of one year per station. Continued monitoring is recommended for waterbodies that exhibit toxic
effects. The database also includes the results of one-time sample collections made during special
studies. This report summarizes data collected to date and informs potential data users of the existence
and capabilities of the program database. The report will serve to document the current database design
and solicit ideas to maximize its utility. The validation of toxicity test results using in situ toxicity testing and
the results of biosurveys for selected waterbodies is also discussed.
About one-third of the stations sampled on multiple dates have exhibited recurrent toxic effects to at least
one test species (Appendix B). This percentage is high, because investigators have targeted waterbodies
with known or suspected water quality problems. Waterbodies that have exhibited recurrent toxicity are
candidates for more intensive assessments, aimed at confirming the occurrence of toxic conditions or
aquatic life use impairment, and determination of sources or causes of toxicity.
The ambient toxicity monitoring program has provided a useful assessment tool for the identification of
waterbodies with the potential for aquatic life impairment. Response from participating agencies suggests
that interest in the program remains high. Requests for increased resources for testing and additional
testing capabilities (bulk sediment & marine tests) have been received. Opportunities for aquiring these
capabilities should be explored. Also, the Regional Environmental Services Division should assume an
active role in assisting other agencies with special studies required to determine or document the sources of
toxicity for waterbodies that have exhibited toxic effects.

Introduction
Environmental Protection Agency (EPA) Region 6 has conducted an effluent toxicity testing program for
over thirteen years. The Regional laboratory conducts standard tests by evaluating the response of
organisms exposed to municipal and industrial effluents. Besides detection of effluent toxicity, results have
been used to evaluate the sensitivity of test methods, and the relative toxicity of Standard Industrial
Categories (Crocker, ej aj. 1989). Although useful from a regulatory standpoint, effluent testing is of limited
value for water quality assessment, because of the inability to evaluate potential synergistic, antagonistic, or
additive effects of multiple contaminant sources. Investigators have documented the ability to predict
aquatic community response based on results of effluent testing in conjunction with ambient toxicity testing
(Bastian ej aj., 1990; Birge ej aj., 1989; and Mount ej a]., 1985a-b and 1986a-d).
Ambient toxicity testing, as a water quality assessment tool, complements chemical monitoring with the
direct assessment of the compound physiological effects of multiple contaminants or contaminant sources
on test species. Although biosurveys provide similar information, aquatic community impairment resulting
from conventional pollutants or habitat limitations may mask potential effects of toxicants. Laboratory
toxicity testing also offers the ability to observe reproductive or teratogenic effects of contaminants that may
not be apparent from a community-level biosurvey.
In 1990, the Region 6 State/EPA Ambient Toxicity Testing Program was initiated to establish a system for
the assessment of ambient toxicity. The program was developed to encourage State agencies to integrate
ambient toxicity testing into water quality assessments, to encourage States to acquire testing capabilities, to
assess potential toxicity in Region 6 waterbodies, and to evaluate the effectiveness of implemented toxicity
control measures. Regional staff encourage State and local agencies to participate in the program by
collecting samples at monitoring sites. Samples are tested by the Region 6 Houston Laboratory. Lab
personnel forward results to the Region 6 Environmental Services Division and the collecting agency.
Region 6 States have participated in the program to varying degrees. Oklahoma and Texas agencies have
collected water samples quarterly from selected sites. The New Mexico Environment Department has
collected samples during intensive surveys. The Arkansas Department of Pollution Control and Ecology
and the Louisiana Department of Environmental Quality have collected samples for a special study on the
Mississippi River. Currently, over 1,040 tests have been conducted on samples from about 144 stations.
Data from 180 tests conducted during a special study on the Rio Grande are unavailable for public review,
pending completion of the final study report. These results were included in summary statistics, but are not
included in data tables.
This report will summarize data collected to date and inform potential data users of the existence and
capabilities of the database. Also, the report investigates potential use of the data for environmental
indicators, and encourages continued participation in the program. The report will serve to document the
current database design and solicit ideas to maximize its utility.
Methods
Regional staff recommend quarterly collection of ambient water and biannual collection of sediment for a
minimum of one year to increase the probability that intermittent toxicity will be detected. Continued
monitoring is recommended for waterbodies that have exhibited toxic effects. The database also includes
the results of one-time collections made during intensive surveys or special studies.
Grab samples of ambient water are collected on a single day, in sufficient volume (two gallons) to provide
for renewal of test water throughout the test period. This approach is inconsistent with guidance (Weber ej
aj., 1989), developed primarily for regulatory application, which suggests daily sampling or a minimum of
three samples collected every other day. The decision to collect a single sample for testing is based on
consideration of personnel and travel costs for renewal sample collection. Samples are generally collected
during other ambient monitoring, and require no additional travel. This approach has proven effective for
the primary objective of this program, i.e., screening for potential ambient toxicity.
-------
Water samples are collected from the main flow of the stream in a clean polyethylene container(s) rinsed
with ambient water before filling. Sediment samples are composited from a minimum of three subsamples
of the upper layer of recently deposited, unconsolidated sediment. Subsamples are composited and mixed
before being transferred to a clean glass or polyethylene containers). Collecting equipment is thoroughly
cleaned between sites and rinsed with ambient water before use. Upon collection, water and sediment
samples are placed in ice for shipment to the laboratory.
In the laboratory, sediment elutriates are prepared by combining a subsample from the homogenized
sediment sample with appropriate culture water. The sediment and water are combined in a sediment-to-
water ratio of 1:4 by volumetric displacement. After combining, the mixture is tumbled end-over-end for
approximately 24 hours at 3 - 4 °C. After settling, the elutriate is siphoned off and filtered through a 1.5
micron glass fiber filter.
Standard laboratory tests and statistical data analyses are conducted according to Short-term Methods for
Estimating the Chronic Toxic'rtv of Effluents and Receiving Waters to Freshwater Organisms (Weber, et a].,
1989), Short-Term Methods for Estimating the Chronic Toxicitv of Effluents and Receiving Waters to
Marine and Estuarine Organisms (Weber, et a]., 1988), and Methods for Measuring the Acute Toxic'rty of
Effluents to Freshwater and Marine Organisms (U.S. EPA, 1991). Test species and methods are described
in Table 1.

Data Compilation
Regional staff enter and maintain test data in a Microsoft Access for Windows™ relational database. Three
data tables contain (1) station location details, (2) toxicity test conditions and results, and (3) chemical test
results (Figure 1 & Appendix A). State station numbers and sample identification numbers are key fields
that link the tables. The software forces maintenance of referential integrity between the tables to preclude
test data entry where supporting data is nonexistent. Data entry forms contain validation checks that
prevent entry of erroneous numeric values. The Windows™ environment provides remarkable advantages
for data entry with the ability to copy and later paste key field data to and from memory, eliminating
repetitive data entry.
-------
The data tables may be exported for use with other
relational database software, after reestablishing
links. Also, some or all of the data fields may be
exported in a single table for use with spreadsheet
programs.
A backup copy of the database is made after each
data entry session. Annually, the database will be
exported to labeled diskettes in an ASCII format and
maintained by the Environmental Analysis Section.
Hardcopies of test results will also be stored in the
Houston laboratory.

Results and Discussion
About one-third of the stations sampled on multiple dates have exhibited recurrent toxic effects to at least
one test species (Appendix B). This percentage is high, because investigators have targeted waterbodies
with known or suspected water quality problems. Waterbodies that have exhibited recurrent toxJcity are
candidates for more intensive assessments, aimed at confirming the occurrence of toxic conditions or
aquatic life use impairment. Priority for investigation should be based on the frequency and degree of
observed toxicity as well as other important factors, such as waterbody designated uses, actual uses,
economic importance, endangered species, and known or suspected causes of impairment.
Initially, Oklahoma agencies were the only major source of sediment samples, as other agencies opted to
collect only water samples. Therefore, sediment data in the database is limited. With regard to test
species, Ceriodaphnia dubia and Pimephales promelas (Fathead Minnow) have been used routinely. The
Daphnia pulex acute test was in use when the program was initiated. Cyprinodon variegatus (Sheepshead
Minnow) has been used for some saline or estuarine waters. Figures 2. & 3. show the relative breakdown
of approximately 1,040 tests for sample types and test species.

The database offers an opportunity to further examine the relative sensitivity of selected toxicity test
methods. For Ceriodaphnia dubia and Pimephales promelas, 340 pairs of side-by-side tests have been
conducted on ambient water samples. Ninety-seven pairs of side-by-side tests were conducted on
sediment samples using these species. Twenty-eight (28%) percent of the water samples, and thirty (30%)
percent of the sediment elutriates, caused significant toxic effects to at least one test species. Graphs in
Figure 4. are based on the seventy-six water samples and nineteen sediment samples that caused toxic
effects to either one of the two species. The results strongly suggest that Ceriodaphnia dubia is a more
sensitive test species, although this comparison may be biased by specific causes of toxicity in the assessed
waterbodies. The results of Pimephales promelas tests may be more important as an indicator of potential
causes of toxicity, rather than as an indicator of potential toxic effects, since this species indicated toxicity
only six times when Ceriodaphnia dubia did not. Similar comparisons using Daphnia pulex or Cyprinodon
variegatus were not made, because of the limited amount of data for these species.

Although data for side-by-side sediment elutriate and water testing is limited, results confirm the importance
of collecting both samples. While sediment samples are more difficult to collect, sediment elutriates
yielded positive toxicity results more frequently than water samples. These findings are consistent with
observations made by Bastian et aj. (1989).
The toxicity screening procedures, as described, have important limitations. The collection of single grab
samples allows the possibility that intermittent toxicity may not be detected. The sediment elutriation
procedure will extract only those contaminants that are water-soluble or loosely bound to the sediment
(Nriagu and Lakshminarayana, 1989). The fact that any given station has not tested positively, does not
rule out the possibility that water quality or sediment quality problems exist.
During an assessment of the Guadalupe River near Victoria, Texas, Trebatoski (1991) used both laboratory
and in situ toxicity tests. The study was designed to investigate the potential impact of a domestic
wastewater treatment facility on the river and to examine the utility of ambient toxicity testing. Caged
fathead minnows were exposed to the effluent and the river, at an upstream site and two downstream sites,
for a 48-hour period. Both the in situ and laboratory tests demonstrated effluent toxicity. The test results
differed in that acute effects were observed in the field (100% mortality after six hours), whereas, chronic
effects were observed in the laboratory (55% mortality after eight days). Results of in situ and laboratory
tests were consistent regarding instream conditions, as neither test demonstrated significant toxicity at
upstream nor downstream sites.
It should be noted that the Pimephales promelas embryo-larval survival and teratogenicity test routinely
used in the ambient toxicity monitoring program differs from the larval survival and growth test required of
National Pollutant Discharge Elimination System (NPDES) permittees. The embryo-larval test was
selected as a more cost-effective initial screening test. When a NPDES permittee is suspected as a source
of toxicity, the larval survival and growth test should be conducted. Also, investigators should make return
trips to the srte(s) to collect samples for renewal of test water. The ambient toxicity monitoring program
sampling protocols will be revised in the future to include these recommendations.
-------
Potential for Development of Environmental Indicators
Ambient water and sediment quality tests may serve as environmental indicators if comparisons of results
are made over time for given stations. Because additions and deletions of stations may occur, program
data should not be used collectively as an environmental quality indicator. For example, an agency may
opt to temporarily discontinue monitoring of waterbodies that frequently exhibit toxicity while corrective
actions are implemented. This may result in the appearance of improving conditions, if alternate stations do
not exhibit toxicity. Conversely, the selection of several new stations that continually exhibit toxicity may
produce the appearance of deteriorating conditions. Variability in meteorological conditions may also
cause temporary declines or increases in the occurrence of ambient toxicity resulting from nonpoint
sources. The data may be useful for regional environmental indicators, over a period of many years, using
a consistently monitored subset of stations.
On a waterbody or station-specific basis, data will be useful as an environmental indicator in shorter terms.
For example, the installation of dechlorination or nitrification facilities at a specific treatment facility, or the
implementation of best management practices to control nonpoint contaminant sources may result in an
immediate reduction or elimination of the occurrence of positive toxicity tests.
Kolbe (1994) presents an example of how ambient toxicity data are applied as an environmental indicator
for a specific waterbody. The Phillips 66 Refinery and Petrochemical Complex located in Brazoria County,
. Texas, discharges treated wastewaters to LJnnville Bayou. The discharge contributes almost all instream
flow during dry weather. Phillips 66, the only permitted point source on the bayou, discharges an average
of four-million gallons per day. Previous studies associated with this discharge have documented impacts
such as oily sheens, elevated pH, low dissolved oxygen, and high ammonia and sulfide concentrations.
Severe impacts to fish communities of LJnnville Bayou have been observed during several studies. During
the most recent survey in August 1992, investigators collected nine fish species at an upstream site;
however, no fish could be collected 0.4 miles downstream from the discharge (mosquitofish, Gambusia
affinis, were observed in the shallows at the downstream site). Only five fish species were collected nine
miles downstream, and mosquitofish comprised 97% of the individuals in this sample. Ambient toxicity
testing allowed investigators to identify toxicity as a probable contributing factor to observed fish community
impairment. Effluent toxicity at this facility was attributed to chlorides, ammonia, and one or more organic
toxicants.
Phillips 66 has completed several treatment plant upgrades in attempts to achieve compliance with permit
conditions. The most significant improvements resulted from the identification and removal of ammonia
sources in September 1992 and the startup of activated sludge and powdered activated carbon treament
systems in April 1993. Recent ambient toxicity test results suggest a reduction in the occurrence of ambient
toxicity that appears to coincide with the removal of ammonia sources (Figures 5. and 6.) Historically, water
samples collected from LJnnville Bayou at Hasema Road (Station No. 1300.0726), located immediately
downstream from the discharge, caused toxic effects to both Ceriodaphnia dubia and Pimephales
promelas. Recent tests have shown no significant effects to test organisms exposed to ambient water
collected from this site. Follow-up studies are being conducted to monitor the compliance status of the
facility and future trends in the condition of aquatic communities of LJnnville Bayou.
Conclusions & Recommendations
The ambient toxicity monitoring program has proven useful for identifying waterbodies with the potential for
aquatic life impairment. Although data for side-by-side laboratory toxicity tests and in situ testing is limited,
results indicate that toxicity testing is a reliable indicator of instream conditions where habitat quality or
conventional pollutants are not limiting. About one-third of the stations sampled on multiple dates have
exhibited recurrent toxic effects to at least one test species. The frequency of observed toxicity is high,
because investigators have generally targeted waterbodies with known or suspected water quality

problems. Waterbodies that have exhibited recurrent toxicity are candidates for more intensive
assessments, aimed at confirming the occurrence of toxic conditions or aquatic life use impairment, and
determination of sources or causes of toxicity. Effluent testing may be conducted where point sources are
suspected as the primary cause of instream toxicity. Toxicity identification evaluations (TIEs), chemical
analyses, and/or biological assessments may be useful for documenting the causes and instream effects of
observed toxicity.
States should continue to monitor those waterbodies exhibiting toxicity until successful corrective actions are
completed. It may be prudent to temporarily discontinue monitoring at some stations to allow other
waterbodies to be screened. The Regional Environmental Services Division should assume an active role
in assisting other agencies with special studies required to determine or document the sources of toxicity for
waterbodies that have exhibited toxic effects. For some waterbodies, such studies have been conducted or
are currently underway. The information from these studies should be compiled for inclusion in the
database.
Response from participating agencies suggests that interest in the program remains high. Requests for
increased resources for testing and additional testing capabilities (bulk sediment & marine tests) have been
received. Opportunities for acquiring these capabilities should be explored.
The utility of the Pimephales promotes chronic test should be reviewed in future data analyses and reports.
Data suggest that the test generally lacks the sensitivity to detect toxic conditions that are not demonstrated
by the Ceriodaphnia dubia test. The results of Pimephales promelas toxicity tests may be more important
as an indicator of potential causes of toxicity, rather than as an indicator of potential toxic effects.
Many other data sources exist which could augment the database. An active program of data acquisition is
recommended. This will facilitate use of the data and prevent potential data loss. Efforts should also be
directed toward database modifications necessary to make the data more accessible to potential users.
