HYDROLOGY OF AN ABANDONED COAL-MINING AREA NEAR MCCURTAIN, HASKELL COUNTY, OKLAHOMA

By Larry 0. Slack

ABSTRACT

Water quality was investigated from October 1980 to May 1983 in an area of abandoned coal mines in Haskell County, Oklahoma. Bedrock in the area is shale, siltstone, sandstone, and the McAlester (Stigler) and Hartshorne coals of the McAlester Formation and Hartshorne Sandstone of Pennsylvanian age. The two coal beds, upper and lower Hartshorne, associated with the Hartshorne Sandstone converge or are separated by a few feet or less of bony coal or shale in the McCurtain area. Many small faults cut the Hartshorne coal in all the McCurtain-area mines. The main avenues of water entry to and movement through the bedrock are the exposed bedding-plane openings between layers of sandstone, partings between laminae of shale, fractures and joints developed during folding and faulting of the brittle rocks, and openings caused by surface mining the overburden being shattered and broken to form spoil. Water-table conditions exist in bedrock and spoil in the area. Mine pond water is in direct hydraulic connection with water in the spoil piles and the underlying Hartshorne Sandstone.

Sulfate is the best indicator of the presence of coal-mine drainage in both surface and ground water in the Oklahoma coal field. Median sulfate concentrations for four sites on Mule Creek ranged from 26 to 260 milligrams per liter. Median sulfate concentrations increased with increased drainage from unreclaimed mined areas. The median sulfate concentration in Mule Creek where it drains the reclaimed area is less than one-third of that at the next site downstream where the stream begins to drain abandoned (unreclaimed) mine lands.

Water from Mule Creek predominantly is a sodium sulfate type. Maximum and median values for specific conductance and concentrations of calcium, magnesium, sodium, sulfate, chloride, dissolved solids, and alkalinity increase as Mule Creek flows downstream and drains increasing areas of abandoned (unreclaimed) mining lands. Constituent concentrations in Mule Creek, except those for dissolved solids, iron, manganese, and sulfate, generally do not exceed drinking-water limits. Reclamation likely would result in decreased concentrations of dissolved solids, calcium, magnesium, sodium, sulfate, and alkalinity in Mule Creek in the vicinity of the reclaimed area.

Ground water in the area is moderately hard to very hard alkaline water with a median pH of 7.2 to 7.6. It predominantly is a sodium sulfate type and, except for dissolved solids, iron, manganese, and sulfate, constituent concentrations generally do not exceed drinking-water limits. Ground-water quality would likely be unchanged by reclamation.

The quality of water in the two mine ponds is quite similar to that of the shallow ground water in the area. Constituents in water from both ponds generally do not exceed drinking-water limits and the water quality is unlikely to be changed by reclamation in the area.

INTRODUCTION

Coal is the most abundant fossil fuel in the United States, and the quantity mined probably will increase to meet our eneray needs. The United States Congress in passing the Surface Mining Control and Reclamation Act of 1977 (Public Law 95-87) recognized the need for "...the protection of public health, safety, and the general welfare from adverse effects of coal mining practices..." and "...the restoration of land and water resources and the environment previously degraded by adverse effects of coal mining practices including measures for the conservation and development of soil, water (including channelization), woodland, fish, and wildlife, recreation resources, and agricultural productivity." The law established an Abandoned Mine Reclamation Fund to be paid by all operators of coal-mining operations to the Secretary of the Interior.

As of January 1982, 28,622 acres of land disturbed by surface mining for coal in eastern Oklahoma (5,793 acres in Haskell County) are unreclaimed and referred to as "orphan (abandoned) coal mine lands" (Oklahoma Conservation Commission, 1983). Practically all the unreclaimed areas were mined prior to the Oklahoma Mining Lands Act of 1971, which reguired mined areas be graded to a rolling topography, the topsoil replaced, and the area seeded or planted. In Oklahoma, the Oklahoma Conservation Commission has the responsibility of administering the State program of reclamation of abandoned mine lands.

In January 1982, Secretary of the Interior James G. Watt approved Oklahoma's Abandoned Mine Land Reclamation Plan (Oklahoma Conservation Commission, 1983), allowing Oklahoma to begin applying for about S3.3 million in reclamation funds (or 50 percent of all fees collected from active coal mine operations in Oklahoma since enactment of the Surface Mining Act). Since then, the State has been submitting detailed plans for high-priority projects, with an emphasis on hazardous highwalls, impoundments, subsidence and improperly sealed shafts from old underground mines.

Purpose and Scope

The purpose of this report is to evaluate the water resources of an abandoned coal-mining area near McCurtain in Haskell County in the Oklahoma coal field (figs. 1 and 2) and to appraise the probable effects of reclamation on water-quality, based primarily on data collected from October 1980 to May 1983. These data include: (1) Photographic and topographic data for the area: (2) records of five test holes and one pre-existing well, (3) laboratory analyses of dissolved major constituents and trace metals in water from these wells, (4-) water-level stage and contents records for two coal-mine ponds, (5) laboratory analyses of dissolved major constituents and dissolved and total trace metals in water from each pond: (6) temperature, pH, specific conductance, and dissolved oxygen profiles for both ponds; (7) continuous stream-stage data at three sites on Mule Creek: (8) periodic stream-discharge data at four sites on Mule Creek and at the outlet of east pond, which discharcres to Mule Creek: and (9) laboratory determinations of dissolved major constituents and dissolved and total trace metals in water from four sites on Mule Creek.

Information on the geology of the area, as related to hydrology, was obtained from reports by Oakes and Knechtel (194-8) and Marcher and others (1983). Information on soils is summarized from a report by Rrinlee (1975) and climatic data are summarized from a report by Holbrook (1975).

Site-Numbering Systems

Wells, ponds, and other miscellaneous sites at which hydrolooic data were collected for this study (fig. 2) were assigned site or station numbers based on the grid system of latitude and longitude. The system provides the geographic location of the well or miscellaneous site and a unigue number for each site. The number consists of 15 digits. The first six digits denote decrees, minutes, and seconds of latitude: the next seven digits denote degrees, minutes, and seconds of longitude: and the last two digits (assigned seguentially) identify the wells or other sites within a 1-second grid.

Stream sites were assigned eight-digit downstream order station numbers. However, for purposes of this report, the terms "site" and "station" are synonymous and the terms "site number" and "station number" are used interchangeably.

Geographic Setting

The McCurtain area is in the McAlester marginal hills geomorphic province (Johnson and others, 1972) and is in the Arkoma geologic basin. In this province, the rocks have been folded to form east-trending anticlines and synclines. The landscape is characterized by irregular hills and ridges generally capped by erosion-resistant sandstone and covered with scrubby trees and brush. The intervening broad valleys have been formed by weathering and erosion of thick, easily eroded shale and are vegetated with native grasses, shrubs, wild flowers, and weeds.

The principal economic activities in the McCurtain area have been associated with coal mining and cattle grazing since about 1900. The last surface mining in the Mule Creek-east pond-west pond area was completed in Ouly 1968. Currently (May 1983) coal is being mined northeast and northwest (downstream) of the project area. The extent of past surface mining in the immediate study area is perhaps best illustrated by close spacing of topographic contours shown in fiaure 3. A map showing potentially strippable coal beds in southeastern Haskell County (Friedman and Woods, 1982) is shown in figure 4.

Reclaimed, partly reclaimed, and unreclaimed "disturbed" coal lands in the McCurtain area as of 3une 1973 are shown in figure 5. The "disturbed" lands are primarily surface-mined coal lands but also include some small adjacent "disturbed" areas. The estimated contributing drainage to Mule Creek from reclaimed and unreclaimed areas (table 1) is less than the total reclaimed and unreclaimed area because of impoundments. Upstream from site A at State Highway 31 (station 07245580) are 42 acres of unreclaimed land most of which does not contribute to Mule Creek except during periods of intense rainfall--and 68 acres of reclaimed land (fig. 5). Most of the flow of Mule Creek at State Highway 31 is from reclaimed surface-mined lands and undisturbed (unmined) lands. Land use immediately surrounding abandoned mine lands has been determined for the entire county by the Oklahoma Conservation Commission (1983) as follows: pasture, 69: forest, 21: urban, 8; and cropland, 2.

Climate

Precipitation records have been collected at McCurtain for 35 years and temperature records for 22 years. Roth, precipitation and temperature records have been collected for 70 years at Eufaula (about 34- miles west of McCurtain); these data are considered representative of the Haskell County climate (Holbrook, 1975).

The area has a warm, temperate climate. Spring and autumn usually are mild and summers are hot. Temperatures reach 100° F about 12 days each year. Winters are comparatively mild, although the temperature is less than 32° F an average of 7 days each year. Average annual precipitation is about 43 inches. On the average, 35 percent of the year's total moisture falls during the spring, 27 percent during summer, 23 percent during autumn, and 15 percent during winter (Holbrook, 1975). Much of the precipitation results from short-duration, sometimes severe, thunderstorms of varying intensity which commonly occur during April to 3une, but can occur during any month. The last freeze in the spring occurs around March 30: the first freeze in autumn, about November 4-. Average annual lake evaporation is about 53 inches.

GROUND WATER

The occurrence, movement, and storage of ground water in the McCurtain area largely is controlled by the lateral and vertical distribution of rock units and their physical characteristics, especially permeability, and by the geologic structure.

Bedrock in the area is shale, siltstone, sandstone, and coal of the McAlester Formation and Hartshorne Sandstone of Pennsylvanian age. The Hartshorne Sandstone, about 100 to 200 feet thick, overlies the Atoka Formation and underlies the McAlester Formation. Two coal beds are associated with the Hartshorne Sandstone: the upper and lower Hartshorne coal. However, the two coals converge or are separated by only inches to a few feet of bony coal or coaly shale in the McCurtain area (Oakes and Knechtel, 1948). In Haskell County the Hartshorne Sandstone crops out on the crests and flanks of anticlines.

The McAlester Formation in Haskell County consists mostly of silty shale, but at widely spaced intervals it contains several erosion-resistant sandstones. The upper McAlester (Stigler rider) coal, the McAlester (Stigler) coal, and the Warner Sandstone Member of the McAlester Formation overlie the Hartshorne Sandstone.

Structurally, the McCurtain area is dominated by the Milton anticline which extends into Haskell County from northwestern Le Flore County. The axis enters Haskell County at sec. 13, T. 8 N., R. 22 E., plunging southwestward to section 29 about 2 miles southwest of McCurtain. Many small faults cut the Hartshorne coal in all the McCurtain mines: both normal and reverse faults occur.

The main avenues of water entry to and movement through the bedrock are the exposed bedding-plane openings between layers of sandstone, partings between laminae of shale, overburden shattered and broken during surface mining, and fractures and joints developed during folding and faulting of the brittle rocks. Although faults may be water conduits, they also may be barriers if the openings are sealed.

Water-table conditions exist in bedrock and spoil and the water in the bedrock and spoil is in direct hydraulic connection with the water in the east and west ponds. (See Pond Characteristics section.) Water levels are shallow in private wells in the McCurtain area. Only 2 of 34 private wells in southeastern Haskell County east of Stigler and south of the Arkansas River had water levels greater than 32 feet below land surface when measured in 1966-67 (Marcher, 1969). In fact, none of the five wells in T. 8 N., R. 22 E (for which McCurtain is approximately the center) had water levels greater than 32 feet below land surface (Marcher, 1969).

Four wells were drilled in spoil piles on the north side of east pond (fig. 2). The wells were drilled by the reverse air rotary method and cased with 4-inch diameter polystyrene; 10-foot sections of slotted casing were placed at the water-producing zone or at the bottom of each well. In addition, well 5 was drilled on the peninsula of land between Mule Creek and east pond (fig. 2). A preexisting well, well 6, was discovered just north of the spoil piles on the north side of the west pond. Well records are summarized in table 2. X-ray diffraction analyses of spoil-pile cuttings are summarized in table 3. Water-level measurements in the six wells were made approximately guarterly. A continuous water-level recorder was placed on well 6.

SURFACE WATER

Stream-Discharge Characteristics

Continuous stage (water level) records were collected at three sites on Mule Creek (sites B, C, and D, fig. 2). Miscellaneous discharge measurements were made at these three sites: at the outlet of east pond that discharges to Mule Creek at site E; and at site A at State Hiahway 31. Because the predominantly shale bedrock lacks the capacity to store water, streams in the area are ephemeral and most of their discharge is the result of storm runoff lasting a few hours or days after precipitation. During all of the period of record, however, flow at the downstream sites (sites C and n on Mule Creek) was maintained by flow from east pond via the outlet from the pond. (See Pond Characteristics section.) Base flow from east pond to Mule Creek was about 0.5 ft /s. The maximum measured discharae at site C on Mule Creek was 336 ft 3 /s (December 3, 1982), at which time flow in the

O

outlet from east pond was 23 ft /s.

Pond Characteristics

Continuous stage records were collected at east pond and west pond (fig. 2). East pond is connected to Mule Creek through a break in the wall between east pond and Mule Creek, which is referred to as the outlet from east pond (site E, fig. 2). During storms when there is runoff to Mule Creek upstream of east pond, Mule Creek discharges to east pond as well as downstream. During a recession following the storm and during base flow east pond discharges to Mule Creek. West pond, however, is self-contained; that is, there are no streams or tributaries draining to or from west pond. Both ponds receive precipitation falling within their basins and are in direct hydraulic connection with water in the spoil piles and the underlying Hartshorne Formation, as indicated by the similarity of stage (water level) at east pond, west pond, and well 6 and their response to precipitation (figs. 6 and 7).

Computer-generated sketches of east pond and west pond, based on sonar-depth determinations, are given in figures 8 and 9. These drawings show what the mine ponds would look like if the water from each were completely removed. The east pond is viewed from an "altitude" of 4-5 feet and an azimuth of 315° (or from the southeast). The west pond is viewed from an "altitude" of 4-5 feet above the present water surface and an azimuth of 4-5°(or from the southwest). East pond has a mean volume of 5,782,000 cubic feet, a mean depth of 21.6 feet, and a surface area of 267,000 sguare feet. The west pond has a mean volume of 2,067,000 cubic feet, a mean depth of 12.9 feet, and a surface area of 160,000 sguare feet (table 4-).

WATER QUALITY

All natural waters contain mineral constituents dissolved from the rock and soil with which the water has been in contact. The concentration of dissolved constituents primarily depends on the type of rock or soil, the length of contact time, pressure, temperature, and mixing conditions. In addition to these natural conditions, man's activities, such as disposal of wastes, agricutural practices, and activities associated with coal mining and oil-and-gas-field development can have a significant effect on the chemical quality of water.

In natural waters, the major cations--calcium, magnesium, sodium, and potassium and the major anions--carbonate/bicarbonate (alkalinity), chloride, and sulfate--generally constitute more than 95 percent of the total ions in solution. Water can be categorized, or typed, according to the percentage of each of the major ions. For example, in a calcium sulfate type water, calcium constitutes more than 50 percent of the cations and sulfate more than 50 percent of the anions. If none of the cations or anions constitutes more than 50 percent of its respective ion group (or 25 percent of the total ions), the water is described as a mixed type.

Minimum, maximum, and mean of water-guality analyses are given for the wells in tables 5-10: for each station on Mule Creek including the outlet from east pond in tables 11-15; and for the ponds, in tables 16-19. The number of determinations, median, minimum, and maximum values of selected constituents and properties in water for the grouped stations are compared in tables 20 to 23. The complete water-guality data (table 25) used in obtaining the statistical tables follow the list of references at the end of this report.

Water guality was evaluated in relation to the National Primary and Secondary Drinking Water Regulations (U.S. Environmental Protection Agency, 1976a and 1979, respectively). The Primary Drinking Water Regulations are enforceable in public water systems by either the U.S. Environmental Protection Agency or the States. Secondary Drinking Water Regulations are not Federally enforceable. They pertain to the esthetic gualities of drinking water and are intended as guidelines for the States.

Concentrations for most chemical constituents in this report are given in milligrams per liter (mq/L) and micrograms per liter (yg/L). Specific conductance is given in micromhos per centimeter at 25° C; pH is given in standard pH units.

Ground Water

The ground water from six wells was predominantly a sodium sulfate type. The water was a moderately hard to very hard alkaline water with a median pH of 7.2 to 7.6 (table 21). Median specific conductance and concentrations of sodium, calcium, magnesium, sulfate, alkalinity, and dissolved solids (residue) were approximately the same (within 10 percent) in water from wells 3, 5, and 6 as median concentrations in water in east pond. Median specific conductance and concentrations of calcium, magnesium, sulfate, and dissolved solids (residue) were approximately twice as great in water from well 1 as in water from any of the other five wells or from the two ponds, probably due to well 1 being finished at the top of a clay layer and having a small yield. At times well 1 is dry: at other times well 1 can be bailed dry.

In water from all six wells, the maximum concentrations of the following dissolved metals were less than limits in the the Primary Drinking Water Regulations (U. S. Environmental Protection Agency, 1976a): arsenic, chromium, and lead less than 50 yg/L; cadmium less than 10 yg/L: and mercury less than 2 yg/L (table 23). The maximum concentrations of dissolved selenium in water from wells 2 to 6 were less than the 10-yg/L limit. The median concentration of dissolved selenium in water from well 1 (table 21) was less than the limit: however, the maximum concentration (17 yg/L) exceeded the limit (table 23).

Median concentrations of dissolved iron in water from wells 2 and 3 (table 21) and all concentrations of dissolved manganese in water from all six wells (table 22) exceeded the recommended limits in the Secondary Drinking Water Regulations (U.S. Environmental Protection Agency, 1979) of 300 yg/L for iron and 50 yg/L for manganese.

All concentrations of dissolved solids were greater than 500 mg/L and all concentrations of dissolved sulfate were greater than 250 mg/L--secondary limits for public water supplies--(table 22). Other values were within the secondary limits: pH within the 6.5 to 8.5 range; dissolved chloride less than 250 mg/L, dissolved copper less than 1,000 ug/L: and dissolved zinc less than 5,000 ug/L.

Mule Creek and Outlet of East Pond

The quality of the water at Mule Creek at site A at State Highway 31 is representative of water quality for an area draining a previously mined (both surface and underground) area which is no longer being mined, has been partly reclaimed, and is being used for qrazinq--essentially a description of the lower Mule Creek and east and west pond areas after reclamation. (See Geographic Setting section.) Water in Mule Creek at site A generally had much less dissolved solids than at the downstream sites.

All concentrations of dissolved arsenic, cadmium, chloride, chromium, copper, lead, mercury, selenium, and zinc for the four sites on Mule Creek and the outlet of east pond to Mule Creek were within primary and secondary limits (table 23). Maximum concentrations of dissolved sulfate were within secondary limits at only two of the five sites: Mule Creek sites A and R. Maximum concentrations of dissolved iron and manganese exceeded secondary limits at all four Mule Creek sites (A-D). (See table 23.) Median values for specific conductance, and dissolved solids, calcium, magnesium, sodium, sulfate, chloride, cooper, lithium, and strontium were about 2 to 3 times larger for the next downstream station (Mule Creek, site B) than for Mule Creek site A (table 21). However, median dissolved aluminum, iron, lead,

As shown in tables 1 and 21, median values for calcium, magnesium, sodium, sulfate, chloride, dissolved solids (residue), alkalinity, and specific conductance increase as Mule Creek flows downstream and drains increasing areas of the abandoned mining lands (from site A to site R to site C to site D).

The large increase in median dissolved solids (residue) between sites B and C on Mule Creek was entirely due to drainage from east pond. During base flow there was no flow at site R on Mule Creek past a shale dam; all flow at site C on Mule Creek was from east pond. During base flow, the upper 0.5 foot of east pond empties into Mule Creek. The median dissolved-solids concentration at the outlet from east pond was about 70 percent of the median dissolved-solids concentration in east pond, due to the dilution effect of Mule Creek emptying into east pond during the first run-off.

East and West Ponds

The water quality in east and west ponds was virtually the same, based on milliequivalent-percent (mean concentrations) of major ions (see fig. 10). Roth ponds were sodium sulfate type and very hard alkaline waters. Roth ponds had median concentrations of calcium, magnesium, sodium, sulfate, dissolved solids (residue), and alkalinity similar to those for wells 2 to 6, although the median concentrations of sodium, sulfate, dissolved solids, and alkalinity were somewhat less in west pond (table 21).

Maximum concentrations of dissolved arsenic, cadmium, chromium, lead, mercury, and selenium (table 23) in both ponds were less than limits in the Primary Drinking Water Regulations (U.S. Environmental Protection Agency, 1976). Maximum concentrations of chloride, dissolved iron, copper, and zinc were less than the limits in the Secondary Drinking Water Regulations (U.S. Environmental Protection Agency, 1979); however, median concentrations (table 21) of sulfate and dissolved solids (residue) exceeded secondary limits. Median dissolved-manganese concentrations in both ponds were less than secondary limits; median dissolved-manganese concentrations in west pond were about one-third those in east pond.

HYDROLOGIC EFFECTS OF SURFACE MINING AND RECLAMATION

Physical Changes

Surface mining for coal and subseguent reclamation in the Oklahoma coal field may cause short- and long-term changes in the hydrologic system. The following description of the coal-mining process as practiced in Oklahoma is summarized from Oohnson (1974-) to show how some of these changes may occur (see fig. 11).

In a surface-mining operation, first a trench or box cut is made through the overburden to expose the coal which is then removed. As each succeeding cut is made, the overburden or spoil is placed into the cut previously excavated. Successive cuts are mined until the overburden thickness becomes so great that the coal can no longer be mined profitably. The final cut leaves an open trench bounded by the last spoil pile on one side and the undisturbed highwall on the other. The ridges of spoil are graded to a rolling topography and revegetated with pasture grasses. The final cut and other depressions partly fill with water from precipitation, ground-water seepage and, if in direct contact with surface water, for ex ample east pond, surface-water inflow. The revegetated area usually is not grazed until the grass has become well established.

The mining in any given area may not always follow the pattern outlined in the previous paragraph. For example, both underground and surface mining for coal have occurred in the McCurtain area. Also, upgradient of Mule Creek at site A the area contributing to flow (table 1) has been reclaimed and is presently used for grazing; downgradient, including sites B, C, and D along Mule Creek, and east and west pond, the area largely is unreclaimed. Furthermore, the Mule Creek and east and west pond areas were mined on successive runs from 1964- to 1968.

A readily apparent change in the hydrologic system resulting from surface mining is the creation of additional water storage in the last mine cut shown in figure 11. East pond and west pond have volumes of about 133 and 4-7 acre-feet, respectively. Such ponds provide habitat for aguatic and semiaguatic wildlife and could be stocked with fish as has been done in other areas of the coal field. Some fish have been observed in both ponds. Other physical changes in the hydrologic system may include (1) changes in permeability and ground water storage, and (2) changes in runoff, streamflow characteristics, and drainage patterns.

1. Changes in permeability and ground-water storage

Overburden in the southern part of the Oklahoma coal field consists mainly of shale with some siltstone and sandstone; these rocks have minimal porosity and permeability (Marcher and others, 1983). During mining, however, the overburden is broken and shattered to form spoil with many openings that may facilitate the entry, movement, and storage of water. Water stored in the spoil may (a) move into adjacent bedrock, (b) be slowly discharged to streams, and (c) be used by plants. During reclamation the spoil material may be compacted and thus decrease infiltration of water.

2. Changes in runoff, streamflow characteristics, and drainage patterns

Observations in various parts of the Oklahoma coal field show that if appropriate reclamation procedures are used and climatic conditions are favorable, grasses on reclaimed spoil may be more lush and have denser growth than the original native vegetation (Marcher and others, 1983). This denser plant growth tends to retard overland storm runoff so that it has more time to soak into the soil and, as a conseguence, less water reaches streams during times of normally high runoff. Conversely, water stored in the spoil, under some circumstances, may be released slowly to streams thereby sustaining streamflow during dry periods. The overall resulting change in streamflow would be to decrease peak discharges and to extend periods of low flow.

Streamflow characteristics also may be affected by interception of runoff in mine ponds and depressions left in the reclaimed areas. In the McCurtain area, drainageways in parts of sees. 16, 20, 21, 22, and 29, T. 8 N., R. 22 E. have been disrupted by mining and reclamation so that some of the overland flow is intercepted before it can reach Mule Creek and, in some instances after it has reached Mule Creek. (See Geographic Setting section.) Additional interception on Mule Creek occurs because of dams created by beavers. Reclamation in the vicinity of east pond and west pond alone, because of the small area involved, likely would have little effect on runoff and streamflow characteristics. The principal drainage pattern for the area generally would be unchanged.

Chemical Changes

Minerals in the overburden and coal are in equilibrium with their environment as long as that environment is not changed. Mining and subsequent reclamation disturb that equilibrium and the minerals react with various chemical components of their new environment such as water, oxygen, and plant acids.

Sulfate is the best indicator of coal-mine drainaqe in the eastern Oklahoma coal field. The principal sources of sulfate include the weatherinq of qypsum (CaS(\) and the oxidation of various iron sulfides such as pyrite (FeS£) and marcasite (FeS2). Iron pyrite (FeS2) occurs naturally with coal, and alonq with other mininq wastes is deposited in spoil piles near mininq activities. Once exposed to oxygen (02) and water (H 20) pyrite can be oxidized to release sulfuric acid (h^SOiJ and ferrous sulfate (FeSOi^), with a corresponding decrease in pH of the solution (or increase in H+ ions):

7 2 2 FeS 2 + - 0 2 + H^ > Fe+ z + 2 H+ + 2 SO^2

The same reaction occurs in the interior of active and abandoned coal mines, and where coal seams crop out.

The variability of sulfate concentrations in streams draininq mined areas primarily is due to the quantities of iron sulfide and calcium sulfate minerals in spoil material, the lenqth of time of exposure of these materials to weathering, the length of time water is in contact with the spoils, and the quantity of water leavinq the mined areas. As shown in figure 12, concentrations are greatest during low flow, when contact time with spoil has been fairly long and water draininq from spoil material may constitute a significant part of the flow. Sulfate concentrations are less during high flow when contact time is short and dilution occurs.

Median sulfate concentrations at sites A, B, C, and D on Mule Creek ranged from 26 to 260 mq/L and increased with increased area of unreclaimed surface-mined areas drained (fig. 5, table 1). The median sulfate concentration in Mule Creek at site A where it drains the reclaimed area is less than one-third of that in Mule Creek at site B, the next site downstream where the stream drains about 159 acres of unreclaimed surface-mined lands (table 1). The range of sulfate concentrations in Mule Creek at sites C and D is similar to the concentration in Mule Creek at site F about 1 mile northwest (downqradient)--where streamflow consists of mine drainage and runoff from areas affected by surface mininq of coal (fiq. 5, table 24-). Mine drainaqe in the McCurtain area contains sulfate concentrations (1,040 mg/L, site C: and 1,370 mq/L, site I) exceedinq the maximum determined in Mule Creek (94-0 mg/L, site C: and 980 mq/L, site P): the sulfate concentration of 1,4-50 mq/L in settlinq-pond overflow, site d, exceeded the maximum for Mule Creek by about 50 percent. The sulfate concentration in settlinq-pond overflow, site 0, was about 28 times larqer than the maximum sulfate concentration in Mule Creek at site A draininq the reclaimed area.

If the study area were reclaimed, the quality of water in Mule Creek would improve to a limited extent. Rased on the water duality in Mule Creek at site A, maximum and median concentrations of sulfate and dissolved solids (which are directly proportional to sulfate concentrations) would be decreased, perhaps to within secondary limits for drinking water. Maximum and median specific conductance and concentrations of calcium, magnesium, sodium, chloride and alkalinity, which increase with drainage from increasing areas of abandoned coal-mine lands, would be decreased.

The small (about 100 mg/L) sulfate concentration in Club Lake (site H, fig. 5) likely represents the optimum concentration after reclamation for area mine ponds and lakes not in direct contact with coal beds or spoil piles. After reclamation, however, sulfate concentrations and concentrations of most other water-guality constituents likely would be virtually unchanged in east and west ponds, which are in direct hydraulic contact with coal beds as well as the spoil piles.

Similarly, the ground water also is in direct contact with coal beds and after reclamation likely would have sulfate concentrations and water quality characteristics that were about the same as prior to reclamation.

On the basis of taste and laxative effects, the recommended maximum limit for sulfate is 250 mg/L in waters intended for human consumption in areas where sources with less sulfate concentrations are or can be made available (U.S. Environmental Protection Agency, 1979). Acclimation to sulfate is rapid and many people can drink water with as much as 600 mg/L of sulfate and not experience any laxative effects (Peterson, 1951).

The pH of a solution is an indicator of how acidic or alkaline a solution is. A pH of 7.0 indicates neutral water. The greater the pH (more than 7.0), the more alkaline a solution is: the lesser the pH (less than 7.0), the more acidic. Common vinegar has a pH of 2 A to 3.4-: sea water, about 8; saturated lime, 12.4-. In natural water, the pH usually is within the range of 6.0 to 8.5, depending on the eguilibrium between chemical species dissolved in the water (Hem, 1970).

The net result of the pyrite-oxidation eguation is that two molecules of sulfuric acid are released for each molecule of the original pyrite dissolved. However, most ground and surface water in the Oklahoma coal field has a pH greater than 7.0 (alkaline) because of the buffering (neutralizing) effect of the carbonate-bearing minerals such as siderite, calcite, and ankerite which commonly occur in large quantities in spoil in parts of the area. Where the minerals are part of the spoil, acidic mine drainage is neutralized rapidly. In the McCurtain area, spoils contain large guantities of hydroxide-bearing minerals such as kaolinite and chlorite (table 3). Although a calcareous layer is exposed in the McCurtain area (T. 8 N., R. 22 E., Oakes and Knechtel, 194-8, p.32), little calcareous material was detected in the spoil pile analyses (table 3). Therefore, the neutralization of acidic mine drainage in the McCurtain area is more likely to be caused by interaction with hydroxides than carbonates.

50

Consequently, in both the immediate project area and generally in the entire Oklahoma coal field, pH is not a good indicator, on an areal basis, of the effect on water quality by discharge from abandoned or reclaimed coal mine lands. In fact, unlike many areas of the country that have reported an acid-mine-drainage problem associated with surface mining, water in Mule Creek at site A draining the reclaimed area has a smaller minimum pH--6.5 versus 7.2--and median pH--6.7 versus 7.6 to 7.8--than water from the unreclaimed areas (tables 21 and 22). Not only is this true for the project area, but it generally is true for the entire Oklahoma coal field. However, a pH of 3.0 to 4-.0 has been reported (Doerr, 1961) in drainage from a few isolated strip pits in the State.

Iron and manganese are common components of rocks and soils and, in water may originate from leaching of rocks and minerals. Other sources of these elements in water include industrial wastes, municipal wastes, corroded metal, and acid mine drainage.

Total-iron and total-manganese concentrations less than 1,000 yg/L (micrograms per liter) are nontoxic to freshwater aguatic life (U.S. Environmental Protection Agency, 1976b, p. 80, and McKee and Wolf, 1963, p. 215) and are essential to certain physiological functions of aguatic life. The maximum dissolved-iron and dissolved-manganese concentration limits, 300 and 50 yg/L, respectively, recommended for drinking water by the U.S. Environmental Protection Agency (1976b and 1979) are intended to prevent objectionable tastes and to minimize staining of clothing and plumbing. Iron can impart a bittersweet astringent taste detectable by some persons at concentrations greater than 1,000 or 2,000 yg/L (American Public Health Association and others, 1976, p. 207).

Maximum concentrations of total iron and manganese for Mule Creek generally increased with increased drainage from unreclaimed areas. The large maximum total-iron (1,900 yg/L) and manganese (120 yg/L) concentrations in Mule Creek at site A indicate that even if the east pond-west pond area were reclaimed, large iron and manganese concentrations exceeding secondary drinking water limits would occur occasionally downstream. In fact, the maximum total-iron concentration for the reclaimed area was greater than three times the 600 yg/L concentration (3.P. Savage, Lone Star Steel Co., written commun., 1978) in Mule Creek at site F (fig. 5) downstream of the Starlight Mine.

SUMMARY

Bedrock in the McCurtain area is shale, siltstone, sandstone, and coal. Water-table conditions exist in bedrock and spoil in the area. Mine pond water is in direct hydraulic connection with water in the spoil piles and the underlying Hartshorne Sandstone. Surface and ground waters in the abandoned coal-mining area predominantly are a sodium sulfate type and moderately hard to very hard alkaline waters. Properties and constituent concentrations in surface and ground waters, except for dissolved solids, iron, manganese, and sulfate, generally do not exceed drinking-water limits.

Sulfate is the best indicator of the presence of coal-mine drainage in both surface and ground water in the Oklahoma coal field. Median sulfate concentrations for four sites on Mule Creek ranged from 26 to 260 milligrams per liter. Median sulfate concentrations increased with increased drainage from unreclaimed mined areas. The median sulfate concentration in Mule Creek where it drains the reclaimed area is less than one-third of that at the next site downstream where the stream begins to drain abandoned (unreclaimed) mine lands.

Reclamation likely would result in decreased concentrations of dissolved solids, calcium, magnesium, sodium, sulfate, and alkalinity in Mule Creek in the vicinity of the reclaimed area. However, the Quality of the ground water and the guality of water in the mine ponds that are in direct hydraulic connection with the ground water are unlikely to be changed by reclamation.
