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.

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: Samrle 1 2 3 . • . k Total Median* Median* 011 021 012 022 013 023 • Olk • 0 2k a b Total i n 2 n 3 • . . N / n 4 a\ 2 N 2 ab * Refers to overall median of the combined samples. 8 ------- 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. 10 ------- SECTION II REGIONAL WATER QUALITY SUMMARY ii ------- 12 ------- 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. 13 ------- Fecal Coliform Bacteria The map on the facing sheet illustrates the general locations of the water quality monitoring stations contained in the Table of Critical Stations and Parameters . Below are listed the most critical stations in the region. Fecal coliform bacteria WQT values for the States of Montana and Utah were based on USGS data only. g. WQI 1.

The table also suggests that nitrogen problems are more pronounced during low streamflow conditions. Below are the stations that had the highest WQI values for nitrogen in the region: Avg. WQI 1.

Stations where WQI values for Nitrogen approached or exceedec critical levels for at least one month during 1978. 17 ------- 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. Below are the stations in the region with the highest phosphorus WQI values: Avg. WQI 1. S Platte R at Henderson, CO 100 2. Big Sioux R at Brandon, SD 100 3. S Platte R at 88th Ave., Denver, CO 99 4.

Stations where WQI values for Phosphorus approached or exceeded critical levels for at least one month during 1978. 19 ------- Total Dissolved Solids (TDS ) High TDS concentrations are prevalent in the lower elevations of Region VIII where surface geologic formations are sedimentary. Hydrology affects the contribution of TDS to surface waters in the form of variable precipitation and the attendant Surface—ground water interrelationships. Stations having the highest IDS WQI values in the region are as follows: Avg. WQ.L 1. Mizpah Cr at Olive, MT 92 2. E Fork Armells Cr nr Colstrip, MT 84 3. Salt Cr nr Sussex, WY 84 4.

Stations where WQI values for Total Dissolved Solids approached or exceeded critical levels for at least one month during 1978. 21 Total Dissolved Solids ------- Suspended Sediment 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 suspended sediments are: WQ I 1. Powder R at Arvada, WY 100 2. White R nr Oacoma, SD 93 3.

Stations where WQI values for Suspended Sediments approached or exceeded critical levels for at least one month during 1978. 23 Suspended Sediments ------- Trace Elements 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: WQI Uncompahgre River at Ridgway, CO (Cu= 78) Fountain Creek at Pueblo, CO (CthlOO) Clear Creek above Golden, CO (Pb 78) Redwater River at Vida, MT (As400) Red River at Emerson, Manitoba (CN100) Little Missouri River nr Watford, ND (Cu100, Cr= 68, Zn= 65 ) Heart River at Mandan, ND (CN=100) 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.” 24 ------- Figure 6. Stations where WQI values for Trace Elements exceeded criteria levels during 1978. 25 Trace Elements ( Th t or approactnna cr’lcaI evels • Ahnve critica) ------- 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. The stations in the regions where the highest turbidity WQI values were observed are: Avg. WQI 1. Powder R at Moorhead, WY 86 2. San Juan R nr Bluff, UT 75 3. Arkansas R nr La Junta, CO 73 4.

Stations where WQI values for Turbidity exceeded criteria levels during 1978. 27 U A N ------- 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 Junta, the Jordan River between Bluffdale Road and New State Road, the Souris River near Verendrye, the Red River between Fargo and Grand Forks, and the Big Sioux River at several stations between Watertown and Richiand, South Dakota. 30 ------- STORET Number Criteria/Std .

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. 35 ------- Col orado Table 1.

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. 113 ------- 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.

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. 129 ------- 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. 130 ------- TABLE 26.

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. 135 ------- COLORADO 136 ------- TABLE 27.

ABSTRACT 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. I ?.
