WATER QUALITY IN GAINES CREEK AND GAINES CREEK ARM,

EUFAULA LAKE, OKLAHOMA

By Ooanne K. Kurklin

ABSTRACT

Based on samples collected from May 1978 to May 1980 and analyzed for major anions, nitrogen, trace elements, phytoplankton, and bacteria, the water in Gaines Creek and the Gaines Creek arm of Eufaula Lake was similar with respect to suitability for municipal use. Water from Gaines Creek had a pH range of 5.7 to 7.6 and a maximum specific conductance of 97 microsiemens per centimeter at 25° Celsius, whereas water from the Gaines Creek arm of Eufaula Lake had a pH range of 6.0 to 9.2 and a maximum specific conductance of 260 microsiemens per centimeter at 25° Celsius. Dissolved oxygen, pH, temperature, and specific conductance values for the lake varied with depth.

With the exceptions of cadmium, iron, lead, and manganese, trace-element determinations of samples were within recommended national primary and secondary drinking-water standards. When compared to the National Academy of Sciences water-quality criteria, phytoplankton and bacteria counts exceeded recommendations; however, water from either Gaines Creek or Eufaula Lake could be treated similarly and used as a municipal water supply.

INTRODUCTION

Municipalities generally treat surface-water supplies before distributing the water to customers. Ordinary domestic requirements for drinking, cooking, and bathing can be met if there is no sediment in the drinking glass or bathtub; if the water is sterilized so that it doesn't contain disease causing water-borne organisms; if the water tastes good; and if the water has the proper hardness (American Society for Testing and Materials, 1967). Other requirements for lawns, gardens, swimming pools, and decorative fountains need to be considered. To meet these requirements, a municipality needs to select a natural water that meets national drinking-water regulations or that can be treated to meet those regulations.

PURPOSE AND SCOPE

The cities of Wilburton and McAlester, Oklahoma, have projected the need for an additional water source for municipal and industrial uses. The U.S. Bureau of Reclamation requested that the U.S. Geological Survey provide data for comparing the water quality of Gaines Creek near Higgins, Oklahoma, and of the Gaines Creek arm of Eufaula Lake (fig. 1). The purpose of this report is to characterize the water quality in Gaines Creek near the site of the proposed Higgins reservoir and in the Gaines Creek arm of Eufaula Lake, with emphasis on the suitability of the water for municipal use.

METHODOLOGY

Field determinations and water-quality sampling for this study were performed from May 1978 to May 1980. Four sampling transects between points on opposite lake shores, identified as A-A 1 , B-B 1 , C-C 1 , and D-D 1 in figure 1, were established along the Gaines Creek arm of Eufaula Lake. Sampling sites were located at the midpoint of each transect; these sites are identified as sampling sites A-D. Sampling site E was established on Gaines Creek near Higgins, Oklahoma.

Each lake transect was sampled quarterly for physical properties, major inorganic constituents, major nutrients, trace elements, phytoplankton, and bacteria. Samples were collected 3 ft below the water surface and 1 ft above the lake bottom at the center point of a transect. Only mid-depth samples were collected when lake depths were shallow at a transect. Depth profiles for dissolved oxygen, pH, water temperature, and specific conductance also were made at the center point of a transect and at a minimum of two other verticals along each transect.

Gaines Creek near Higgins (site E) was visited each month and, when flow occurred, samples were collected and a discharge measurement was made. Stream samples were collected for major inorganic constituents, major nutrients, trace elements, phytoplankton, and bacteria. A series of longitudinal profiles, extending from the proposed pumping site on the lake, sampling site D, to the proposed dam site on Gaines Creek, sampling site E, were completed.

All water-quality samples were collected and analyzed by methods outlined by Brown and others (1970); Goerlitz and Brown (1972); and Greeson and others (1977). Biological analyses were made at the U.S. Geological Survey's laboratory in Doraville, Georgia. The remainder of the laboratory analyses were made at the Survey's laboratory in Arvada, Colorado. Microbiological analyses were performed by U.S. Geological Survey personnel in Oklahoma.

WATER QUALITY AS RELATED TO SUITABILITY FOR MUNICIPAL SUPPLY

To determine the suitability of a water source as a municipal or industrial supply, the physical, chemical, and microbiological data are compared to established drinking-water standards. Water-quality standards established by the U.S. Environmental Protection Agency are summarized in tables 1 and 2. Oklahoma State drinking-water standards are summarized in table 3.

Selected constituents from the national primary drinking-water regulations the mandatory limits that apply to the physical, chemical, and microbiological characteristics of water that affect the health of consumers are listed in table 1. They are applicable to virtually all public water systems and are enforceable by the State or Federal governments.

The national secondary drinking-water regulations (table 2) deal with the esthetic qualities of drinking water. They are not federally enforceable and are intended as guidelines for regulation by the State.

Selected water-quality data for Galnes Creek and the Galnes Creek arm of Eufaula Lake are summarized in table 4 (at back of report). Additional data for these sites are provided in table 5 (at back of report). The data from each of the five sites, when compared with the drinking-water standards, indicate that constituent concentrations from May 1978 to May 1980 were within the limits with the exceptions of cadmium, iron, lead, and manganese.

The following sections briefly describe physical properties, chemical constituents, and biota as they pertain to municipal water supplies. Results of sampling and analysis conducted during this study are summarized.

Physical Properties

Dissolved Oxygen

Dissolved oxygen in lake water has an essential biological role; for most organisms, oxygen is a requisite for life. Concentrations of dissolved oxygen are dependent on several factors including water temperature, agitation, and the degree of photosynthesis. In most lakes, the phytoplankton contribute the majority of the oxygen supply. Additional oxygen is added by exchanges with the atmosphere at the lake surface. Decreases in oxygen are due mostly to the respiration of plants, animals, and the aerobic bacteria involved in decay of organic matter. On a purely physical basis, the warming of the summer epilimnion could account for an oxygen decrease. The solubility of oxygen decreases as temperature increases. A deep stratum of the lake may be lacking in oxygen if light does not penetrate the lake. As a result, respiration and decomposition prevail in the deep strata and oxygen is depleted faster than it is produced.

Dissolved oxygen in bodies of water used for municipal water supplies is an indicator of satisfactory water quality in terms of minimal residuals of biologically available organic materials. In addition, dissolved oxygen in the water column prevents the chemical reduction and subsequent leaching of iron and manganese, principally from the sediments (U.S. Environmental Protection Agency, 1973). These metals cause taste problems or staining of plumbing fixtures and other surfaces that contact the water in the presence of oxygen (National Academy of Sciences, National Academy of Engineering, 1974).

Dissolved oxygen also is required for the biochemical oxidation of ammonia ultimately to nitrate in natural waters. This oxidation of ammonia decreases the chlorine demands of waters and increases the disinfection efficiency of chlorination (National Academy of Sciences, National Academy of Engineering, 1974).

The disadvantage of large concentrations of dissolved oxygen in water used as a source of municipal water supply is the increased corrosion of metal surfaces in both water-treatment facilities and distribution systems (National Academy of Science, National Academy of Engineering, 1974). Such corrosion, in addition to direct damage, can increase the concentration of iron (and other metals), which may cause taste or staining problems or both (U.S. Environmental Protection Agency, 1976).

Depth profiles of dissolved oxygen are shown in figures 2-5. Generally, greatest near the water surface and 1 fluctuations occurred in early summer dissolved oxygen ranged from 0 to 12.7 mg/L saturation ranged from 0 to 121 (table 6, at

The pH of a natural water supply water-treatment processes and may con structures, distribution lines, and corrosion can add such constituents a to the water. Adjustment of pH within natural waters, 5.0 to 9.0, is relatively anticorrosion procedures currently in more narrow range (National Academy Engineering, 1972).

Although water temperature varies both seasonally and areally, the extent of seasonal variation was not determined during this study due to the sampling frequency. Depth profiles of temperature made at sampling sites (figs. 2-5) were compared by site. Depth profiles for May had the greatest temperature variation with respect to depth. Warmer water was present near the surface and cooler water near the bottom. As summer progressed, water temperatures were less variable with depth. Some of the fall depth profiles indicated the beginning of a temperature reversal with bottom temperatures slightly higher than surface temperatures. The water temperature ranged from 4.5 °C in February 1979 to 30.0 °C in May 1978 (table 6).

Specific Conductance

Specific conductance is a measure of the ability of ions in solution to conduct an electrical current. Specific conductance is related to the type and concentration of ions in solution. Specific conductance generally is proportional to the dissolved-solids concentration and can be used to estimate the dissolved-solids concentration. Specific conductance increases with water temperature; however, all specific-conductance values reported in this study were temperature corrected to 25 °C (table 6). Depth profiles for specific conductance are shown in figures 2-5. Specific-conductance values had little variation with depth. The greatest variation occurred temporally, with smaller values in May increasing to larger values in the fall.

Chemical Constituents

Major anions

Sulfate concentrations ranging from 3 to 30 mg/L may be considered normal in lake water (Hutchinson, 1957). Sulfate is important in the formation of chlorophyll and is necessary for plant growth. A limited supply of sulfate can inhibit the development of phytoplankton populations (Reid and Wood, 1976).

The public water supplies of the 100 largest cities in the United States were determined to contain a median sulfate concentration of 26 mg/L and a maximum concentration of 572 mg/L (Durfor and Becker, 1964). Sulfate ions in drinking water can have cathartic effect on occasional users, but acclimatization is rapid (National Academy of Sciences, National Academy of Engineering, 1972).

The national secondary drinking-water standard for sulfate is 250 mg/L (table 2). Dissolved-sulfate concentrations were less than the drinking-water standard in all samples from the study area. Concentrations ranged from 3.1 to 41 mg/L in water from all sites (table 4 and fig. 6).

Chloride is present in all natural waters, but mostly in small concentration (Hem, 1970). Based on studies done for public water supplies of the 100 largest cities in the United States, the median chloride concentration was 13 mg/L with a range of 0 to 540 mg/L (Durfor and Becker, 1964).

Large concentrations of chloride, as part of the dissolved solids in water, can be detected by taste and can lead to consumer rejection of the water supply. The national secondary drinking-water standard for chloride is 250 mg/L (table 2). Dissolved chloride concentrations were less than the drinking-water standard in all samples from the study area. Concentrations ranged from 2.8 to 31 mg/L in water from all sites (table 4 and fig. 6).

Fluoride has potential beneficial effects, but excessive fluoride in drinking-water supplies produces dental fluorosis (an abnormal condition chiefly characterized by mottling of the teeth) that increases with increasing fluoride concentration greater than the recommended limit (National Academy of Sciences, National Academy of Engineering, 1972). Recommended concentrations of fluoride in drinking water are temperature dependent (table 2). Dissolved-fluoride concentrations were less than the drinking-water standard in all samples from the study area. Concentrations ranged from 0.0 to 0.1 mg/L in water from all sites (table 4 and fig. 6).

Nitrogen

Nitrogen is considered one of two major plant nutrients and commonly is identified as a limiting factor for aquatic-plant growth. The primary source of nitrogen is the atmosphere. Nitrogen also occurs in organic, ammonia, nitrite, and nitrate forms. Each form can be utilized by different organisms.

Nutrient enrichment is a natural process in lakes and reservoirs. Man has become a significant contributor of large concentrations of nitrogen to the aquatic systems by activities such as agriculture and urbanization. As more nutrients are made available, plant productivity may increase, and the natural eutrophication or enrichment process accelerates.

The recommended maximum nitrate-nitrogen concentration in public water supplies is 10 mg/L. All the nitrate concentrations determined in water from Gaines Creek and the Gaines Creek arm of Eufaula Lake sampling sites A-E (table 4- and fig. 6), were within drinking-water standards.

Trace Elements

Generally, trace elements occur in most natural waters at concentrations that are not toxic to humans, animals, and plants; they are, in many instances, essential to plant growth as micronutrients. Many trace elements are toxic to humans, animals, and plants when they occur in large concentrations. Large concentrations commonly occur as a result of mining or industrial activities. The presence of trace elements in water supplies has a variety of implications concerning the potability and ultimate other uses of drinking water (Rubin, 1976). Concentrations of selected trace elements in water from Gaines Creek and the Gaines Creek arm of Eufaula Lake (sampling sites A-E) are listed in table 4-. Each trace element will be discussed separately in the following paragraphs. The concentrations generally were much less than the drinking-water standards, with the exception of cadmium, iron, lead, and manganese.

The national primary drinking-water standard for chromium is 50 p,g/L (table 1). All chromium concentrations were less than the national primary drinking-water standard (table A- and fig. 6).

Copper. Copper, although widely distributed in the environment, occurs only in trace concentrations in natural waters because of solubility controls. Copper is essential in the'nutrition of plants and animals but is toxic to some algae. Mining and industrial activities sometimes contaminate water with copper. Copper is esthetically significant in public water supplies because it can cause taste and discoloration problems (Rubin, 1976). Water samples collected from 130 sampling points in the United States had copper concentrations ranging from 1 to 280 [j,g/L with a mean concentration of 15 \ig/L (Kopp, 1969).

The national secondary drinking-water standard for copper is 1,000 [ig/L (table 2). Copper concentrations were much less than the secondary drinking-water standard. Water from Site B had the greatest copper concentation with a maximum of 67 \ig/L (table 4- and fig. 6).

Iron. Iron is an abundant and important element unsurpassed by any other heavy metal in the Earth's crust (Cole, 1975). It is essential to photosynthesizing plants; it is the metal part of some plant cytochromes that function in the transfer of electrons during photosynthesis. It also is a vital element in the respiratory pigments of many animal species and affects many chemical reactions in water. Excessive concentrations may be toxic. Large concentrations of dissolved iron will not be present in natural waters with near-neutral pH. Large concentrations, if they occur, will be found in the suspended phase. Iron is esthetically significant in public water supplies because it can cause taste and discoloration problems (Rubin, 1976).

The national secondary drinking-water standard for iron is 300 (table 2). This limit of 300 \ig/L for iron was exceeded in numerous samples collected during the study. Large concentrations of total recoverable and dissolved iron were found in samples from all sites (tables A- and fig. 6). The largest concentrations were for samples collected near the reservoir bottom.

Lead.--Lead is found in small concentrations in streams due to its minimal solubility. Large concentrations of lead are toxic to humans. Water samples collected from 130 sampling points in the United States had detectable lead concentrations ranging from 2 to 14-0 \ig/L with a mean concentration of 23 p,g/L (Kopp, 1969).

The national primary drinking-water standard for lead is 50 \ig/L (table 1). The lead concentrations in water from the study area were much greater than the drinking-water standard (table 4- and fig. 6). Total recoverable-lead concentrations ranged from 0 to 4-20 [j,g/L.

Biota

Phytoplankton

Phytoplankton are primary producers in the aquatic food chain. Planktonic variability in lakes is determined by the physical, chemical, and biological characteristics of the individual lake. Some information about the degree of lake enrichment can be determined by the phytoplankton members present.

In a study done by W.D. Williams (Cole, 1975) some generalities were cited. The phytoplankton of oligotrophic waters (those that contain few nutrients) includes the desmid Staurastrum, the chrysophyte Dinobryon, noted for its tolerance of only small phosphate concentrations, and the diatoms Tabellaria and Cyclotella. The eutrophic lake (enriched in nutrients) has a different group of diatoms and a mixed group of blue-green algae that may eventually replace the diatoms. As the lake becomes eutrophic, the filamentous diatoms Melosira and Stephanodiscus appear first. If there is agricultural runoff or erosion frqm clear cutting, Asterionella may appear. Later, if sewage enters the lake, Fragillaria may appear.

Hern and others (1979) in a study of some Oklahoma lakes found that whereas desmids and many pennate diatoms are found in oligotrophic waters because they generally cannot tolerate large nutrient concentrations, Cyanophyta, Euglenophyta, centric diatoms, and members of the Chlorococcales generally are associated with eutrophic waters.

Generally, during the study, the greatest number of phytoplankton cells were in the surface samples (table 7, at back of report) where the light penetration was the greatest. The diatoms and blue-green algae were the dominate organisms.

Phytoplankton data (table 7) provide useful information towater-treatment operators. Counts of blue-green algae that exceed 50 percent of the total phytoplankton count usually indicate potential taste and odor problems. Phytoplankton data were collected at all sites. In one-third of the phytoplankton analyses from Gaines Creek, blue-green algae constituted more than 50 percent of the total cells per milliliter. Lake phytoplankton also frequently were dominated by blue-green algae, the most prevalent group.

Diversity of phytoplankton has been determined in several ways because of the observed species changes as a lake becomes enriched. Among the best indices of species are those that are largely independent of sample size (Wetzel, 1975). As defined by the U.S. Geological Survey (1983), "...diversity index is the numerical expression of evenness of distribution of aquatic organisms. The formula for diversity index is:

_d = -

s n. , n. _ i log _ i

There n. is the number of individuals per taxon, n is the total number of

individuals, and s is the total number of taxa in the sample of the

29

community. Diversity index values the sample are the same, to some po organisms in the samples are differ two species results in small divers are populations of several species, diversity to decrease with increasing the slower growth rates attainable number of species with reasonably s temporal variations of regulating enriched waters (Wetzel, 1975).
