EVENTS OF GENERAL INTEREST
On June 6, EPA Administrator Douglas M. Costle and Ing. Humberto Romero
Alvarez, Subsecretary for Environmental Improvement of Mexico, signed an
agreement between the U.S. and Mexico pledging mutual cooperation on
environmental problems, including air and water pollution control on both
sides of the border. Under the agreement, the two nations will exchange
information and personnel and establish parallel projects of mutual concern.
The agreement was the culmination of a dozen years of effort for George B.
Morgan, Di rector of the Las Vegas Laboratory. Over the years, Mr. Morgan
provided extensive consultation and personal guidance in the nation's
environmental concerns, highlighted by hi s aid in setting up an effective air
quality monitoring network in Mexico. He was among the group of EPA
officials who accompanied the Administrator to Mexico City for the signing of
the Memorandum of Understanding.
Charles F. Costa, Chief of the Laboratory's Radiation Monitoring Branch,
was named Federal Employee of the Year by the Southern Nevada Federal
Executive Association. Presented by Las Vegas Mayor William Briare, the
award cited Costa for the important public relations contribution he has made
"... by traveling throughout the state lecturing and talking with audiences
about the operation of the nuclear testing program and the elaborate
precautions taken to safeguard the public health." Costa has been involved
with the Laboratory's off-site radiation safety program since 1962.

BIOLOGICAL MONITORING
In a plutonium metabol i sm study involving the oral feeding of plutonium
dioxide particles of various nuclide combinations to lactating dairy cows,
204 samples were analyzed for piutonium-238 and -239. This is one of a
series of studies on the biological transfer of radionuclides to milk,
tissues, and excreta in 1actating dairy cows. Preliminary results indicated
that differenc ~ between pi utonium-238 and -239 uptake and metabolism are far
less than the approximately 200-fold difference that may be predicted from
other studies which were based on the relative decay rates of pi utonium-238
and -239, or on solubility.
A goat feeding study using additive soil collected from the locale of
Plowshare nuclear events was initiated to determine tissue uptake and
retention of residual radionuclides present in the soil. Individual samples
of soil in which the total radioactivity was estimated by counting were mixed
with molasses, grain and alfalfa pel lets and are being fed to goats over
90-day period. Selected tissues will then be analyzed for radionuclide
content.
Preliminary grazing studies were initiated with rumen-fistulated steers
at five sites of early nuclear testing activities on the Nevada Test Site.
Steers with surgically prepared rumen fistulas will serve as the biological
samplers. As the animals graze the site, samples wil1 be taken periodically
from the contents of their forestomachs for analysis. The objective is to
i nventory the radionuclides available to grazi ng and foraging animals as
related to season and botanical composition of the vegetation and soils the
animal ingests.
The semi-annual roundup of the Nevada Test Site Area 18 beef herd was
conducted. This included the semi-annual sacrifice and necropsy of six
animals from the herd for the sampling of selected tissues for
histopathological and radionuclide analyses. A1 so sampled were two mule deer
that died as result of motor vehicle accidents.
The migratory habits of mule deer that reside on the Nevada Test Site are
of interest to the Department of Energy and the Nevada Department of Fish
and Game on the possibility that these deer may contain radionuclide
concentrations and may be harvested by hunters. A1 though no significant
concentrations of radionuclides have been found in Test Site deer to date,
the deer are being equi pped with radiotransmitter col 1ars and are being
2

-------
tracked weekly via ground and aerial reconnaissance. During this quarter,
plans were made to capture and collar deer on areas of the Test Site other
than their summer ranges on the mesas. The aim is to determine whether deer
migration patterns are similar to those of deer captured in Area 20 of the
Test Site.

MONITORING SYSTEMS DEVELOPMENT
In experiments to compile supplemental data on selected carcinogen
pathways from sources to man, benzene was found to sorb to soils.
Radiolabeled benzene was placed in a calciurn-saturated clay, an
aluminum-saturated clay, and humic material. The cause of the sorption of
the benzene is attributed to both the clay and the soil organic fractions.
The studies indicate that the amount of sorption increases with time up to 48
hours and that the benzene is not being degraded in the soil system.
Completion of the benzene portion of the study will include desorption
and movement of benzene in the above soil type. On completion of the benzene
portion, work will begin on the remaining compounds—carbon tetrachloride,
benzidene, trichloroethylene, and ethylene dibromide.
Other related studies are being conducted to develop an exposure
monitoring methodology for precursors of carcinogens. Present emphasis is
on determining the kinetics of biosynthesis of the carcinogens, dimethyl
nitrosamine, and N-nitrosomorpholine. Background levels of dimethyl
nitrosamine have been found in control mice. Although the source of the
latter compound has not yet been identified, feeding of its precursors to
mice results in dimethyl nitrosamine levels significantly above background.
As part of a study of hydrogen sulfide and non-condensible hazardous
gaseous emissions from geothermal developments, baseline meteorological data
are being collected at five 1ocations within the Roosevelt Hot Springs area
in Utah. Wind speed and direction are being recorded on tape cassettes. To
date, 1 month of hourly data from two sites and 2 month's data from a third
site have been reduced from the cassettes to tabular sunraaries and wi nd
roses. Photovoltaic batteries to power the equipment are being recharged by
means of solar panel s.

-------
EQUIPMENT AND TECHNIQUES DEVELOPMENT
The airborne laser fluorosensor used to monitor chlorophyll a
fluorescence of surface waters was modified to detect and record the water
Raman emission in addition to the chlorophyll _a fluorescence signal. The
Raman signal is used to correct the fluorescence signal for variations in
water optical transmission. Preliminary flight tests of this modified system
were made~ Flight test data analysis and further flight testing are planned
for the coming quarter.
An airborne nadir-looking laser transceiver system is being developed for
monitoring molecular pollutants in the troposphere. The major components
have been acquired and the initial design was modified so as to reorient the
telescope. This modification simplified many alignment problems that existed
previously and diminished overal1 aircraft cabin height restrictions.
Negotiations were underway to obtain contractor construction of the framework
and vibration i solation platform.
A beam expander was installed on the laser transmitter portion of the
two-frequency downward-looking 1idar. A program which will scroll the
display data across a video screen was written and is working. Software on
the display portion of the electronics subsystem is being developed. The
feasibility of using the Raman nitrogen 1ine to normalize the
downward-looking 1idar data is also being investigated. Normalization of the
backscatter return using Raman data wilI facilitate the compari son of data
taken at different times and places and even with different instruments. A
significant use of this technique would be to document particulate scattering
over pristine areas before and after energy resource development activities
are begun.
The Laboratory is usi ng Land sat imagery, aircraft multispectral scanner
data, aerial photography and ancillary data as part of a project to develop
and demonstrate a remote sensing technique for evaluating mine ground
stability. Initial test sites wi11 be selected in the Northern Great Plains
area. The project is being conducted in conjunction with the Mining Safety
and Health Administration of the U.S. Depar lent of Labor.
5

-------
In the development of aerial photography interpretation keys, work has
begun in several areas of the country to determine where such imagery can be
used to detect septic tank 1 each field failures.

-------
RADIATION MONITORING
The Las Vegas Laboratory provided radiological safety support for nuclear
testing conducted at the Nevada Test Site by the U.S. Department of Energy
(DOE) during this quarter. Mobile ground and aerial radiological monitoring
personnel were deployed to the off-site areas. Other personnel served as
advisors to the Test Controller for the DOE and coordinated off-site
surveil1ance activities from the Test Site Control Point. No release of
radioactivity occurred as result of the tests.
The Air Surveillance Network, consisting of 48 continuously operating
stations, continued to operate with 61 standby stations through April 10 to
monitor airborne radioactivity resulting from the atmospheric nuclear test
conducted by the People's Republic of China on March 15. The active stations
continued to operate after the shutdown of the standby stations on April 10.
The Mil k Surveil 1ance Network and the Dosimetry Network were routinely
operated and the quarterly exchange of thermoluminescent dosimeters used for
continuously monitoring ambient radiation 1evels at 78 locations was
completed. Routine quarterly milk samples were collected from 21 1ocations
in April. The Standby Milk Surveil 1ance Network was activated for a
readiness check, and samples were collected from 147 locations.
Monthly and annual water samples were collected from wells at 11
locations of the Long-Term Hydrological Program at the Nevada Test Site.
Annual water samples were collected from 20 1ocations at Project Dribble in
Mississippi, 9 1ocations at Project Gasbuggy and 9 1ocations at Project Gnome
in New Mexico, 11 1ocations at Project Rio B1anco and 9 locations at Project
Rulison in Colorado, and 3 1ocations at Project Faultless in central Nevada.
Twelve new wells were augered and/or drilled and cased for special water
sampling at the Project Dribble site to monitor for subsurface tritium
contamination caused years ago by postshot, drill-back, operations.
F ty-eight soi1 samples for the Plutonium-in-Soil Program were collected
along Highway 395 from Little Lake to Montgomery Pass, California* and in Box
Canyon, near Currant, Nevada.

QUALITY ASSURANCE
The Las Vegas Laboratory maintains a repository of standard reference
samples and materials for distribution to users upon request. During thi s
quarter, approximately 300 calibrated radionuclide solutions were distributed
to participating laboratories on request.
At the request of Region 5, on-site laboratory evaluations were conducted
and reports of findings prepared for seven laboratories in the Region. The
laboratories were evaluated on the basis of criteria and procedures for
laboratory certification for monitoring drinking water supplies for
radionuclide contaminants. A 2-day workshop was al so conducted for Region 5
personnel and State personnel of the Region. The purpose of the workshop was
to discuss the difficulties and problem areas in carrying out the
requirements of the National Interim Primary Drinking Water Regulations,
1aboratory certification for monitoring drinking water for radionuclides
under the Safe Drinking Water Act, and general problems in statistics and
methodology.
The ongoi ng laboratory intercompari son studies program, i nvolving
environmental media (milk, water, air, food, soil, and gases) and a variety
of radionuclides, was conducted. Approximately 1,100 samples of known
activity levels were distributed to the 150 participating laboratories for
analyses. Assessment of the precision and accuracy of radioactivity
measurements has been made and computerized reports were sent to
participants.
Evaluation studies of two published methods for the measurement of
radium-228 in water are continuing. Critical steps in the methods have been
identified. One of the methods will be selected and prepared for a
collaborative test for the purpose of validation and publication as a
reference method.

TECHNICAL SUPPORT
At the request of the Office of Toxic Substances, proposed pesticide
label application restrictions have been applied graphically to mapped
demonstration areas in Oklahoma, Arkansas, Louisiana, Alabama and
Mississippi* Interpretation of aerial photography compiled in these label
restriction projects has demonstrated the extremely limited area to which a
pesticide could be applied. Using Endrin as an example, it was shown that 63
percent of the croplands in a 16,000-acre area near Cedar Bluff, Alabama, is
within the 1/8-mile proposed restriction because of water sources in the
vicinity that may be affected. Because of hunan habitation on and near the
locale, 31 percent of the land was within the 1/8-mile proposed restriction.
At the request of the Headquarters Office of Enforcement, the continuity
of two watercourses in northwest New Mexico was established using aerial
photography. Data were collected after a rainfall and again after a lengthy
period of no rain. These data were required in relation to an adjudicatory
hearing on two applications for uranium mine National Pollutant Discharge
Elimination System (NPDES) permits.
As part of a project directed by the Office of Air Quality PIanning and
Standards, Research Triangle Park, the Las Vegas Laboratory will be operating
an instrumented hel icopter to measure ozone, nitrogen oxides, hydrocarbons,
and other parameters upwind of Phi 1adelphia, Pennsylvania. The objective is
to study the impact of photochemical pol1utants in air upwind of a city on
that city's air quality. Planning has been completed and the system was
flight-tested preparatory to an early July departure date. The field work in
Philadelphia is expected to be completed by late August.
Upon request of Regional and other EPA Offices, consultation services
are routinely provided by Laboratory technical and scientific staff. During
thi s quarter, a Laboratory representative participated in the Atchafal aya
Basin, Louisiana, Management Group Subcomnttee activities. Another water
scientist provided technical consultation at a meeting of U.S. Forest Service
scientists from Western States, addressing eutrophication and other water
quality problems of alpine and subalpine lakes.
Aerial imagery col lection flights were flown in support of the Spill
Prevention Control and Counter-measures (SPCC) program at the request of the
Oil and Special Materials Control Division, EPA Headquarters. These include:
9

-------
industrial facilities and waterways in all States of New England.
refineries, bulk oil storage sites, and chemical faciIities in the
vicinities of Bayonne, Linden and Carteret, New Jersey, and Albany, New York,
and in the Port of San Juan, San Juan, Puerto Rico.
oil facilities in Pennsylvania, Maryland and West Virginia.
industrial facilities in Illinois and Indiana.
fifty selected refining and oil storage facilities in Louisiana.
selected refineries and bulk oil storage facilities in Iowa.
selected refineries, bulk oil storage sites, and oil fields in Utah,
Montana and Wyoming.
oil spill and flow from an oi1 production area near Cut Bank,
Montana.
a chemical spill on interstate highway near Bakersfield, Cal ifornia
(Documented extent of spill of endosulfan).
selected industrial facilities in Idaho, Oregon and Washington.
A variety of remote sensing technical support projects was conducted this
quarter for EPA Regional Offices. Listed by Region, these projects entai1ed
the acqui si tion, processing, interpretation, and delivery of data collected
from aerial platforms. The resultant data were presented in the form of
color and infrared photography, map sheets, annotated overlays or other
imagery displays, and detailed narrative reports, as requested by the Region.
REGION 1
Aerial thermal scanning and photographic data were collected on proposed
wastewater treatment sites in Massachusetts, Connecticut and Vermont. The
objective was to identify nonpoint source^ of pol 1 utants, existing land uses,
point source discharges, and malfunctioning on-1 ot septic systems. These
data were requested for the preparation of environmental impact statements.
REGION 3
A thermal scanning survey of discharge water bodies was made to ascertain
whether selected power plants in Pennsylvania, New Jersey and Washington,
O.C., are in compliance with the thermal discharge 1 imitations imposed in
their NPDES permits. These 1imitations are thermal water quality standards
applied outside designated mixing zones. Photographs of the thermal plumes
10

-------
and isothermal data depicted on sealed illustrations of the receiving waters
were provided, showing compliance-noncompliance with the standards in areas
beyond the confines of the assigned mixing zones.
REGION 4
Aerial photographic data were collected to depict 1 and development
encroachment in the area of Everglades City, Florida, for 1itigation support
regarding Section 404 of the Federal Water Pollution Control Act 1977.
Maps showing the locations and distribution of mixed mangroves and black
mangroves along the coast of Florida from Cedar Key to St. Augustine were
produced to assist in establising the ecological value of black mangroves.
The data were compiled from archival Landsat digital data and from archival
photographic data used for ground truth.
Photographic enlargements of an area on the M.K. Ranch in the
Apalachicola Basin, Florida,, were provided as a result of a dredge spoil
restoration study. This information will be used as support in enforcement
and by the Florida Game and Fresh Water Fish Commission to implement a
restoration pi an jointly developed by State and Federal regulatory agencies.
REGION 5
Col or imagery was collected and analyzed for enforcement actions
involving 12 power generating stations and an industrial compl ex located in
the eastern sectors of Michigan and a sewage treatment pi ant in Gary,
Indiana. This information is required to document discharges, floating
debris, oil discharges, surface drainages, and the current status of
construction of the plants.
A resource inventory of the fettle Lake area in Ohio was made with col or
aerial photography which will be used as a common base map for the display of
existing environmental components. Photographic overlays wil 1 be used to
di splay water drainage, vegetation type and extent of cover, exi sti ng land
use, political boundaries, soil types and location, groundwater 1ocation,
significant geologic formations, potential flood-prone zones, types and
habitat 1ocation of rare and endangered wildlife species, and the topography
of the area. Resource areas that have common or mutual relationships will be
combined on a single overlay for ease in future analysis, and each category
of overlays will have a written text to identify significant features or
characteristics of the particular resource component.
11

-------
Thermal infrared and aerial photographic data of Rock River from the
Rockford Sewage Disposal Plant downstream to the town of Oregon, Illinois,
were collected. Coverage includes the construction si te of a new power pi ant
in the Byron area. These data are being analyzed for discharge and mixing
zones from the disposal plant and other industrial facilities and will be
used as archival data for monitoring discharges of new plants as they become
operational .
Photographic data were collected over two smelter sites in Wabash and
Rockport, Indiana, to document emissions and to obtain perspectives of the
smelters and their surroundings, A1 so, an emissions inventory was made of
industrial facilities in Midland, Michigan.
REGION 6
Ten industrial facilities in Beismar, Gramercy, Braithwaite and Baton
Rouge, Loui si ana, were surveyed for NPDE5 enforcement and adjudicatory
hearings. Thermal infrared and aerial photographic data were analyzed to
determine compliance, including the extent of discharges into the marsh and
river areas and the extent of vegetation damage due to chemical or petroleum
spills.
Color photographic over-flights were made of two chicken processing
plants in Arkansas to determine runoff direction and erosion features. A1so,
a stream flow and discharge study of Whitewater Creek id New Mexico was
completed.
A project was begun to locate the source of salt contamination of
farmland in Lincoln County, Oklahoma. Hi storical high altitude and current
low altitude data will be used to detect and delineate vegetation ki 11 and
contamination sources.
REGION 7
Aerial imagery was collected to detect industrial waste lagoon seepage in
Cedar River, Iowa. A second flight will be flown during the summer for
seasonal data to detect seeps and springs which allow groundwater to come to
the surface and drain into the river.
A 1and-use study of strip mines in Missouri was conducted to upgrade the
present inventory of the state's mined 1ands. Imagery was collected to map
vegetative cover, barren land, water impoundments, and adjacent 1 and uses.
The information wi11 be used in the management of the state's mining lands
and activities as related to nonpoint sources of water pollution.
12

-------
REGION 8
A series of flights was flown along the Poplar River in Montana,
including one from Scobey, Montana, to the Canadian border, in emissions
surveys. The objectives were to provide baseline data of air pol1ution
impacts to crops and native vegetation due to emission fallout from a
coal-fired power plant, to provide a thermal characterization of an in-stream
cooling reservoir as influenced by natural and man-induced forces, and to
identify by thermal scan pool areas and temperature-sensitive reaches of the
Poplar River and its tributaries.
Flights were initiated to collect multispectral scanner and aerial
photographic data of outfall inventory and Guernsey silt run along the North
Platte River near Casper and below Guernsey Dam in Wyoming. The data will be
analyzed for the NPDE5 program on the North PIatte between Casper and
Evansville. Also, the data will be analyzed to document turbidity in the
waters from the North PIatte to the Nebraska state line.
REGION 9
The Las Vegas Laboratory plans to fly a helicopter this September in
support of a two-state effort to determine the sources of photochemical
pollution in the Lake Tahoe air basin. Urban expansion in the area,
especially along the South Shore, and pollutant transport from California are
two suspected sources of photochemical oxidant which will be studied.
REGION 10
Region geologists are monitoring various surface mining operations,
hazardous waste disposal sites, landfills and landslides in Oregon and
Washington. Laboratory assistance includes an archival data search from 1974
to the present. Photographic prints of any existing pertinent data are also
being furnished and photographic mi ssions will be flown to obtain data not
available in archives.
A variety of maps depicting thermal conditions, turbidity, oil and
grease, chlorophyl 1 a, and Rhodamine WT dye is being provided to evaluate
water quality and hydraulic characteristics of marinas in the Pacific
Northwest. The data will be used to establish guidelines for review of
construction permits.
Aerial photographic surveys of land features were made of selected forest
range and agricultural sites in the Region. Land feature information was
13

-------
collected and related to in-stream water quality sampling to establish a
causal relationship through modelling techniques.
An air quality problem arising from the agricultural practice of burning
grass fields in the Willamette Valley has prompted a request from the State
of Oregon through the Region for EPA technical assistance. Plans were
completed by the Laboratory to field its 8-26 air qua 1ity monitoring aircraft
and, through its contractor, Northrop Services, Inc., a mobile ground air
quality monitoring trailer to support the state in characterizing the
problem. Smoke from grass fires is of concern to the Oregon State Department
of Environmental Quality which must address the issue in its state
implementation plan. The project will begin during the next quarter.
Aircraft and Landsat data showing annual (1971-1978) changes in housing
density were analyzed to aid the Region in interpreting groundwater quality
information and to identify areas where groundwater monitoring should be
initiated. The analysis area, which has been designated as a "sole source
aquifer" under the Safe Drinki ng Water Act, was the Spokane-Rathdrum Prairie
Aquifer in Washington and Idaho.
As part of the biological sampling study bei ng conducted on the White
River, an intensive survey is planned to investigate the macroinvertebrate
drift phenomena, the efficiency of various sampling techniques , and the
characterization of macrobenthic communities in cold and warm water habitats
and transi tional zones. The aim is to establish biomoni tori ng techniques for
application in the oil shale impact area.
