ABSTRACT
Water and air quality trends and status for the calendar year 1978
were determined for the six states in Region VIII. These states include
Colorado, Montana, North Dakota, South Dakota, Utah and Wyoming. Data
resident in EPA national data banks (STORET, SAROAD) were analyzed.
Statistical tests which detect significant differences between two
populations were utilized to show trends in both air and water quality.
The status and severity of stream pollutants were determined by relating
parameter concentrations to Water Quality Indicator (WQI) values on a
numerical scale from 0 to 100. The status and severity of air
pollutants reported continues to be a direct measure of air quality
standard and alert level exceedences.

INTRODUCTION
Air and water quality monitoring activities have increased substantially
in Region VIII over the past few years both in scope and frequency. These
increases are due to public demand for accurate information about harmful
pollutants in the environment and to the passage of Federal Legislation,
namely, The Clean Air Act Amendments (1979) and the Federal Water Pollution
Control Act of 1972 (Public Law 92-500). To fulfill the requirements of these
legislative mandates State agencies have planned and developed extensive
monitoring networks which have generated a mass of environmental quality data.
The purpose of this report is to present useful analytical summaries for
Region VIII of the Environmental Protection Agency utilizing environmental
quality data resident in the STORET (water) and SAROAD (air) data stc rage and
retrieval systems. This report does not attempt to classify or precisely
determine air and water quality or to analyze detailed cause and effect
relationships. It attempts, rather, to impart a sense of status and trend
(i.e. improvement, degradation, etc.), by observing air and water quality
measurements not only for current severity but also for changes over
successive time periods.
3
-------
SUMMARY AND CONCLUSIONS
Water Quality
Trend analyses (1975—1977 vs. 1.978) of all pertinent water quality data
available in the STORET system for Region VIII indicates that 128 of 546
stations processed experienced significant changes (improvement or
degradation) for at least one parameter group. Of those stations which
exhibited significant trends and which were also found to have concentrations
generally considered at critical levels during 1975, 1976, and 1977, 13 were
found to have improved and 42 were found to have degraded.
The changes in quality that could be mostly attributed to the affects of
man, as indicated by the stations where high ‘fecal coliform bacteria
concentrations are present, were observed at the stations listed below:
Significant Degradation
South Platte R at 60th Ave., Denver, CO
South Platte R at 88th Ave., Denver, CO
Colorado R nr Loma, CO
Arkansas R nr Coolidge, KS
Tongue R at WY-MT state line
Red River of the North nr Perley, MN
French Cr nr Custer, SD
White R nr Ouray, UT
San Juan R nr Bluff, UT
Significant Improvement
Yellowstone R at Huntley, MT
N Platte R biw Casper, WY
4
-------
For the non-point sources of pollution, where total dissolved solids
concentrations have been determined to be at critical levels, degradation
occurred at 7 stations in the region and improvements were noted at 3
stations. Four of these occurrences were at stations on the Arkansas and
South Platte Rivers in Colorado. Also, significant quality degradation was
detected for the suspended sediments parameter at 9 stations on the larger
tributaries of the Missouri River in Montana.
The section of this report entitled “Regional Summary” discusses in more
detail the findings with regard to specific pollutant groups.
5
-------
ANALYTICAL PROCEDURES - WATER
Water quality data (1975-1978) for 546 active monitoring stations in each
of the six States of Region VIII were retrieved from STORET (EPA’s
computerized water quality data base) and screened through computerized
trending techniques. Forty-six STORET water quality parameters which fall in
the general categories of temperature, dissolved oxygen, p 1- I, bacteria, trophic
potential, dissolved solids, suspended solids, aesthetics, and inorganic
toxicants were selected for this trend study and were analyzed in a two step
process. First, to describe pollution severity, a water quality indicator
(WQI) was computed for each observation of each parameter at all active
stations and averaged on a monthly basis. The WQI may vary from zero to one
hundred. A WQI less than 20 represents generally acceptable quality. The
range from 20 to 60 signifies exceedence of water quality standards/criteria
and the WQI greater than 60 represents exceedences of a severe nature.
Wherever color coded maps are used in this report, the color blue, yellow, and
red represent the respective range. Secondly, to determine pollution trends,
the 15th, 50th (median) and 85th percentile values for two time periods were
compared for each parameter with sufficient data. A standard statistical
test, requiring at least six observations for a parameter in each time period
was used to test for a significant difference between the two time periods.
Significant changes in the 50th percentile measurements are generally
indicative of overall changes in concentrations, while significant changes in
the 85th percentile measurement (15th percentile for dissolved oxygen) are
generally indicative of changes during critical periods. The criteria for
determining improvement or degradation is described in a later table.
6
-------
Severity Analysis
Water quality indicators (WQI’s) were computed in order to assess the
relative severity of a pollutant group at a given monitoring station. Each
parameter concentration was graphically converted to a WQI and averaged on a
monthly basis. This technique attempts to relate the concentration of various
water quality parameters to a common numerical scale and is accomplished
through the use of several “severity curves.” These curves which relate
concentration to WQI values were developed by the staff of EPA’s Region X and
exhibit the same general family characteristics and shape of the traditional
curves which were developed for use with the original National Sanitation
Foundation (NSF) Water Quality Index. Severity curves used for this analysis
appear in the appendix.
Trend Analysis
The statistical test (“The Median Test,” Practical Non-Parametric
Statistics W.J. Conover, John Wiley & Sons, Inc., New York, 1971, pages
167—172.) that was used to analyze water quality trends is a non-parai tric
technique for testing the hypothesis that random samples from two or more
populations have the same median. The test is a special application of a
chi-square contingency table test with fixed marginal totals. The same test
can be used against other percentiles than the 50th but the discusssion here
describes only the median.
7
-------
Given k populations each with a random sample of size n 1 , i=1,2---k, a
test statistic can be constructed to test the hypothesis:
H 0 : all k populations have the same median.
HA: at least two populations have different medians.
The test statistic is computed from the 2xk contingency table:

-------
The test for the statistic assumes:
The samples are random.
The samples are independent of each other.
The measurement scale is ordinal.
If all populations have the same median, they have the same
probability of an observation exceeding the median.
A large sample approximation is used to approximate 1. The critical
region of approximate size d corresponds to values of I greater than x 1 -
the (1-a) quantile of a chi—square random variable with k-i degrees of
freedom. If I exceeds x 1 reject H 0 ; otherwise accept H 0 . The author
notes that the approximation may not he satisfactory if more than 20% of the
n are less than 10, or if any of the n 1 are less than 2. It further
qualifies this rule of thumb for larger numbers of samples k.
The test was applied to each pollutant parameter at every station in the
Region not only for the median but also the 15th, and 85th percentiles. Data
observed during the years 1975 through 1977 comprise one test population and
data from the year 1978 made up the other population. Each sample was
required to have at least six observations. This technique made it possible
to detect statistically significant differences between the two time periods.
9
-------
The following procedures were used to determine if the observed
significant differences represented an irnproverrient or a degradation:
Examine the 15th and 50th percentile for dissolved oxygen - for all
other parameters examine the 85th and 50th percentile.
If a significant difference between two time periods for either of
the percentile statistics exists and both percentile statistics
decrease from the first time period to the second, designate this as
improvement. (For oxygen this is a degradation).
If a significant difference between two time periods for either of
the percentile statistics exists and both percentile statistics
increase from the first time period to the second, designate this as
degradation. (For dissolved oxygen this is an improvement).
It was assumed that the samples were random and independent of one
another. Given that these data are time series data, taken at irregular
intervals, affected by seasonal cycles, etc., certain modifications of this
technique might be advisable in future applications.

REGIONAL OVERVIEW OF WATER QUALITY
A Summary of Parameter Groups at or Approaching Critical Levels
The color coded regional map displays that appear in this section
generally describe problem areas identified through computer analysis of
each parameter group. After all pertinent 1978 data resident in the national
STORET data bank were screened they were converted to water quality Indicator
(WQI) values. WQI’s range from 0 to 100 where a value of 20 represents
parameter concentrations equivalent to the water quality standard or criteria
and a value of 60 IndIcates concentrations at some level of severe Impair-
ment. In the graphic representations stations where WQI levels are
between 45 and 60 appear as yellow dots and levels greater than 60 appear as
red dots. The regional maps showing severity are generated from the Table
of Critical Stations and Parameters in the section titled, “State Reports.”
The section on state reports also contains tables of Station and Parameter
Group Coverage for each state. It should be recognized that even though
problems may exist in areas where insufficient data were collected, no
problem condition was reported. Since few occurrences of a critical nature
were noted for temperature, dissolved oxygen, and pH, no maps are presented
to describe these groups.

It is generally apparent from reviewing the Table of Critical Stations and
Parameters that stations having fecal coliform problems also have nitrogen
problems. The table also suggests that nitrogen problems are more pronounced
during low streamflow conditions.

Phosphorus
High phosphorus concentrations are prevalent in the region. Phosphorus
loadings, like nitrogen, are both man—made and natural. Examination of the
Table of Critical Stations and Parameters indicates that water quality
stations located downstream of municipalities exhibit a constant loading
inflow whereas the stations in the remote areas are subject to seasonal
variations.

Characteristically, the locations with high concentrations of suspended
sediments are also those locations where high total dissolved solids
concentrations occur. The Table of Critical Stations and Parameters
illustrates that high suspended solids occur during high streamflow conditions
and high TDS concentrations generally occur during low streamflow conditions.
The stations in the region that exhibited the highest WQI values for

During 1978, a few trace element concentrations exceeding criteria were
detected in the region. Those stations where the highest WQI values were
determined are as follows:

Extremely high concentrations of cyanide as indicated by a WQI value of
near 100 were predominate in the Red River of the North in North Dakota and
Canada. Refer to the Table of Critical Stations and Parameters in the section
entitled “State Reports.”

Turbidity
The Table of Critical Stations and Parameters indicates that WQI values
for turbidity generally parallel those for suspended sediment and that the
occurrences are most pronounced in the lower elevations of the region.
Organic and inorganic constituents make—up this pollutant component and the
susceptibility to be transported with relative ease by overland runoff
(non—point source) is very apparent as represented in the tables.

Temper ature
Only a few scattered occurrences where temperatures were found to he in
minor exceedence of standards were observed. These occurrences were all in
the months of June, July and August; eight were in South Dakota, three were in
Utah and one was in Wyoming. One station on the South Platte River at
Julesburg, Colorado, exhibited a WQI value during the month of July that
approached the critical level.
Dissolved Oxygen
The 88th Avenue station at Denver, Colorado, exhibited WQI values that
exceeded standards as well as some that were above critical levels. There
were three other minor exceedences in Colorado. Seven minor exceedences of
standards occurred in Montana. Critical levels were observed for the winter
months at stations along the Souris River in North Dakota, the James River in
North and South Dakota and the Big Sioux River in South Dakota.
Minor exceedences of standards were noted for the upper Arkansas River in
Colorado presumably during the start of the runoff in April. The Big Thompson
River had a WQI approaching the critical zone during the month of January. A
critical WQI value was calculated for the month of June at the Verendrye,
North Dakota station on the Souris River. Levels approached a critical
concentration on the Cheyenne River near Plainview, South Dakota during
October. Minor exceedences of standards were found for the Shoshone River
below Buffalo Bill Reservoir in Wyoming during the period August through
October.
28
-------
Un-ionized Ammonia
Water Quality Indicator values for un-ionized ammonia were determined at
each station where the STORET parameters, total ammonia (NH 3 -N), temperature
and pH were observed for the same water sample. The calculation procedure is
described in William 1. Willingham’s 1976 report, “Ammonia Toxicity.”
The following stations exhibited ammonia concentrations at or near
critical levels for at least 3 months of the year in 1978:
Avg. WQI
1.. South Platte River at Henderson, CO 36
2. South Platte River at 88th Ave., Denver, CO 46
3. Fountain Creek biw Colorado Springs, CO 32
4. San Miguel at Confluence Dolores R, CO 43
5. Big Sioux at North Cliff Avenue, SD 33
The Souris River near Westhope and near Verendrye exhibited exceptionally
high WQI values in the months of June and July, 60 and 70 respectively.
Amonia standards violations occurred at numerous other stations
especially near urban communities. The findings will be the subject of a
latter report.
Trophic Status
Nitrate and phosphate data are collected at numerous sites in this region
but no definitive standards or criteria have been found generally acceptable
or been adopted for them. The most notable adverse effect of these compounds
(other than deleterious effects, caused by resultant nitrites when nitrates
are chemically reduced) occurs when they are mutually present and provide a
nutrient support for trophic conditions.
29
-------
An attempt was made to determine trophic potential wherever nitrates and
phosphates were observed in a common water sample. The analytical procedure
involved (1) finding the ratio of nitrogen to phosphorus —- if the ratio were
greater than 12 a phosphorus limited condition was assumed -- for a ratio less
than 12 a nitrogen limited condition was assumed, (2) comparing the WQI of the
limiting parameter to a harmonic function of the combined phosphate and
nitrate WQI and reporting the smaller of these two values as the WQI for the
corresponding trophic potential.
2 (phosphate WQI) (nitrate WQI ) vs. phosphate WQI (P-limited) or
phosphate WQI + nitrate WQI nitrate WQI (N—limited)
High trophic potentials occurred most frequently on the South Platte
between Denver and Julesburg, on the Arkansas River between Pueblo and La

STATE WATER QUALITY REPORTS
This section is comprised of four major tables. The table, Ranking
of Critical Water Quality Stations by Pollutant Group is a sumary of
stations where the highest WQI values were noted.
The table, Station and Parameter Group Coverage lists the active
water quality monitoring stations in the state and a count of the number
of data observations for each parameter group present in the STORET data
system for the year 1978.
The Table of Critical Stations and Parameters utilizes the WQI calcu-
lation procedure to determine and display monthly standard exceedences by
pollutant group and station location. This table of pollution severity
also provides the average yearly WQI calculation for critical stations and
a ranking factor for each station and parameter group. A ranking of 1
defines the station at the highest critical level In the State. This table
reports on 1978 data only.
The Water Quality Trend Table lists stations where parameter groups
exhibited significant changes over time as determined by statistical tests.
This table shows quality improvement or degradation In each parameter group
and points out those groups which are at or approaching critical levels.
Data for 1975, 1976 and 1977 were trended against data for 1978 in
determining this table.

SECTION IV
AIR QUALITY REPORT
111

SUMMARY AND CONCLUSIONS
Air Quality
Trend analyses performed on the 1976, 1977 and 1978 air quality data
available in the SAROAD system indicates that 24 of the 91 counties
where sufficient data were available experienced statistically signifi-
cant changes (improved or deteriorated) for at least one pollutant group.
A severity analysis of the 1978 air quality data shows that total
suspended particulates continues to present the most wide-spread
pollutant problem in this region where the 12 of the 17 counties which
exceeded the primary standard also exceeded alert levels. Four counties
exceeded the sulfur dioxide standard and 10 counties exceeded the carbon
monoxide standard.
A comparison of the findings of this report and the report titled
EPA-908/2-78-OO1, Water And Air Quality Trends in Region VIII ” which
included data for 1974-1976 reveals that levels for suspended particulate,
sulfur dioxide, and nitrogen dioxide generally remained at approximately
the same levels over the two time periods. There was a significant
decrease in the number of counties exhibiting carbon monoxide standards
violations both in Colorado and Utah. Ozone violations decreased in
Colorado.

OVERALL REGIONAL AIR QUALITY
The color coded maps which are displayed on the following pages generally
reflects the air quality for the worst site in each county of the region on a
pollutant by pollutant basis. 1978 data analyzed for severity was used to
construct these graphics.

AIR QUALITY STANDARDS
The Environmental Protection Agency has been given the authority to
establish ambient air quality standards which specify, for the principal
and most widespread classes of air pollutants, limitations necessary to
protect the public health and welfare. These pollutants currently are
total suspended particulate matter, sulfur dioxide, nitrogen dioxide,
ozone, and carbon monoxide. Standards for lead have recently been
proposed.
Two types of standards were established. Primary standards are set
at levels to protect human health. Secondary standards are set at levels
to protect against other forms of damage to such things as vegetation and
materials. The numerical vdlu - of * ach standard is listed in Appendix B.
Several causes and the health effects of these pollutants are shown
below;
TSP is a measurement of particles In the a 1 r
(such as soot, mist, and sprays) and includes
non—toxic materials (dust and dirt) as well as
toxic materials (lead, asbestos, sulfates).
Natural and man-made sources contribute to
TSP which affects the respiratory system in
varying degrees depending on particle size
and chemical composition.
Sulfur dioxide (SO), the most common form of
SOz In the atmosphere, results from combustion
of coal and gas or as a by-product in mineral
smelting operations. S02 reacts readily with
other atmospheric pollutants to form sulfates,
a group of compounds responsible for
respiratory ailments (bronchitis, emphysema
and asthma) and the aggravation of heart
disease.
125
-------
NO 2 is a brown gas formed during high
temperature combustion (automobile engines,
power plant boilers), N02 can affect lung
tissue, reduce resistance to disease,
contribute to bronchitis or pneumonia, and
aggravate chronic lung disease. It reacts
with hydrocarbon in the presence of sunlight
to produce photochemical oxidants.
CO is a colorless, odorless, tasteless gas—-
a toxic product of combustion. The
automobile engine represents the major single
source of this pollutant. CO in the lungs
reduces the oxygen available to tissues and
decreases heart and mental functions, visual
perception and general alertness. For those
with heart and lung problems, CO presents a
life—threatening situation.
Photochemical Oxidant compounds are formed
by a complex series of chemical reactions
occurring when hydrocarbons and nitrogen
oxides from motor vehicles or other
emission sources are exposed to sunlight.
Ozone, the critical constituent in
oxidants, is a severe irritant to mucous
membranes and may reduce lung function
or aggravate existing lung disorders.
126

ANALYTICAL PROCEDURES - AIR
Status and Severity Analysis
Status and severity of air quality are determined by comparing
measurements made at monitoring stations to air pollution standards. The
indicator used to characterize air quality status in this manner was the
number of days in which measurements exceed the primary standards at the
worst site in each county. The indicator may not actually represent air
quality for the entire county, however the worst site is always selected
in an area where measured concentrations are affecting some segment of
the population.
Another indicator is used to demonstrate the severity of the problem.
Each pollutant has been assigned an alert level, the t oncentration at
which the public must be notifieii of possible dvcrse health affects.
These values shown in Appendix C are significantly higher than the
standards and are not frequently encountered.
These two indicators correspond to. break points in the Pollutant
Standards Index (PSI) which is becoming the nationwide index for
reporting air quality levels to the public. In the PSI the worst site
pollutant concentration in each metropolitan area is chosen, and the
index is calculated from the concentration at the site referenced to
primary standards and alert levels. These methods are detailed by
pollutant in Appendix D.
Irend Analysis
Most research Indicates that air pollutants are log-normally
distributed. Utilizing this as .umption, the relationship between
127
-------
normally and log—normally distributed variables can be exploited in
formulating statistics that are useful In trend analysis. The statistic
that is a confidence interval estimate of the location of the underlying
distribution is usually the one used, since significant differences in
such a statistic suggests significant differences in the locations of the
distributions in question. In other words, each year has its own dis-
tribution and any significant location shifts from year—to-year would
indicate significant shifts in pollutant concentration. Since the
location of a log-normal distribution is a difficult parameter for which
to formulate a confidence interval, the method 0 f forming a confidence
interval around the location (mean) of the accompanying normal distribu •
tion was used. The bounds on the confidence interval were then converted
back to actual concentration fori . Since more than one interval was
computed for each trend determination, the Bonferronii technique was
utilized, which yielded a family confidence for whatever number of Intervals
that were to be constructed. The method used is as follows:
(1) Take the natural log of every observation, for a particular yr.
(2) find =
n
(3) find s =IE(lnx)2 - (zlnx) 2
n
n-i
(4) construct confidence interval using:
A) lower bound = - ts
B) upper bound + ts
Where t=table, t-value chosen to yield an approximate
90-95% family confidence
1. 28
-------
(5) convert back to original concentration form by doing:
A) new lower bound = elOWer bound
B) new upper bound eupper bound
Each confidence interval for each year is then inspected for any
overlaps. Overlapping years indicate those years to be insignificantly
different whereas non-overlapping years indicate significant shifts In
the geometric mean concentrations. The relative locations of the inter-
vals along a real number line indicates whether or not the concentrations
are increasing or decreasing.

AIR QUALITY NON-ATTAiNMENT AREAS
On March 3, 1978 the Federal Register set forth the attainment status
of all states in relation to the national ambient air quality standards
(NAAQS). Table 26 indicates, on a state by state, pollutant by pollutant
basis the attainment status of every area as submitted by each of the
appropriate state agencies in Region VIII and approved, or as designated
by the Environmental Protection Agency. No distinctions have been made
as to the severity of the violations recorded in the areas designated
by nonattainment in this table. Current status (1978) for each county
containing a nonattainment area in Region VIII is graphically described
on annotated maps in the section dealing with state summaries.

STATE AIR QUALITY SUMMARIES
General Description
The following three graphics appear for each state summary that is
contained in this section:
1. Number of Days that the Primary Standard or Alert Level
was Exceeded .
A bar chart compares 1976, 1977, and 1978 data. Primary standard and
alert violations are recorded for the worst site in the county. For
those pollutants reporting only yearly average primary standard viola-
tions or those reporting no violations, the county was on;itted. If no
data or insufficient data (75% ( f all possible data) were indicated, the
county was omitted. One or more primary standard daily and/or alert
level exceedenceS is shown even though more than one primary level con-
centration is required for a primary standard violation.
2. Status and Trends in Air Quality
A county chart showing current status and trends by nollutunt for the
worst station in the county. If no data or insufficient data were avail-
able in the county, arrows were not shown. Status was determined using
1978 data. Counties with primary standard and/or alert level exceedences
are shown. Trends were determined by comparing the geometric means of
1976, 1977, and 1978 data. Ozone status is based on a 3—year average of
1 hour primary level violations.
3. Non-Attainment Areas
The status of counties containing non-attainment areas is shown by parameter.
If no indication is given, the county did not have a non-attainment area
designation in the March 3, 1978, Federal Register non-attainment area list.
In some cases it appears that the status has changed in certain of these
non-attainment areas.

Water and air quality trerid md status for the calendar year 1978 were
determined for the six states in Reqion VIII. These states include Colorado, Montana,
North Dakota, South Dakota, Utah and Wyoming. Data resident in EPA national data bank
(STORET, SAROAD) were analyzed.
Statistical tests which detect significant differences between two populations
were utilized to show trends in both air and water quality. The status and severity
of stream pollutants were determined by relating parameter concentrations to Water
Quality Indicator (WQI) values on a numerical scale from 0 to 100. The status and
severity of air pollutants reported continues to be a direct measure of air quality
standard and alert level exceedences.
