The Metropolitan Denver Sewage Disposal District and the City and County of Denver operate a sewage-sludge recycling site and a landfill in an area about 15 miles (24 kilometers) east of Denver. The assessment of the effects of these facilities on the ground-water system indicated that five wells perforated in alluvium were found to have markedly degraded water quality. One well was located in the landfill and water that was analyzed was obtained from near the base of the buried refuse, two others were located downgradient and near sewage-sludge burial areas, and the remaining two are located near stagnant surface ponds. Concentrations of nitrate in wells downgradient from fields where sludge is plowed into the soil were higher than background concentra tions due to the effects of the sludge disposal. No evidence of water-quality degrada tion was detected in deeper wells perforated in the bedrock formations.

GROUND-WATER QUALITY NEAR A SEWAGE-SLUDGE

RECYCLING SITE AND A LANDFILL NEAR DENVER, COLORADO

By S. G. Robson

ABSTRACT

The Metropolitan Denver Sewage Disposal District and the City and County of Denver operate a sewage-sludge recycling site and a landfill in an area about 15 miles (24 kilometers) east of Denver. The assessment of the effects of these facilities on the ground-water system included determining the direc tion of ground-water movement in the area, evaluating the impact of the waste- disposal activities on the chemical quality of local ground water, and evalu ating the need for continued water-quality monitoring.

Surficial geology of the area consists of two principal units: (1) Allu vium with a maximum thickness of about 25 feet (7.6 meters) deposited along stream channels, and (2) bedrock consisting of undifferentiated Denver and Dawson Formations. Ground water in formations less than 350 feet (110 meters) deep moves to the north, as does surface flow, while ground water in forma tions between 570 and 1,500 feet (170 and 460 meters) deep moves to the west. Estimates of ground-water velocity were made using assumed values for hydrau lic conductivity and porosity, and the observed hydraulic gradient from the study area. Lateral velocities are estimated to be 380 feet (120 meters) per year in alluvium and 27 feet (8.2 meters) per year in the upper part of the bedrock formations. Vertical velocity is estimated to be 0.58 foot (0.18 me ter) per year in the upper part of the bedrock formations.

Potentiometric head decreases with depth in the bedrock formations indi cating a potential for downward movement of ground water. However, water- quality analysis and the rate and direction of ground-water movement suggest that ground-water movement in the area is primarily in the lateral rather than the vertical direction.

Five wells perforated in alluvium were found to have markedly degraded water quality. One well was located in the landfill and water that was ana lyzed was obtained from near the base of the buried refuse, two others were located downgradient and near sewage-sludge burial areas, and the remaining two are located near stagnant surface ponds. Concentrations of nitrate in

wells downgradient from fields where sludge is plowed into the soil were high er than background concentrations due to the effects of the sludge disposal. No evidence of water-quality degradation was detected in deeper wells perfo rated in the bedrock formations. Continued water-quality monitoring is needed because of the continuing disposal of wastes. A suggested monitoring program would consist of monitoring wells near the landfill twice a year and monitor ing wells near the sludge-disposal areas on an annual basis.

INTRODUCTION

The Metropolitan Denver Sewage Disposal District operates a 2,000-acre (8-km2 ) sewage-sludge recycling site in Arapahoe County about 15 miles (24 km) east of Denver, Colo. (fig. 1). The sludge is hauled by truck to the site and either spread on the ground and plowed into the soil or buried in bulk if the weather is inclement. In addition, the City and County of Denver operates a solid and liquid waste landfill on about 250 acres (1.0 km2 ) adjacent to the sludge-disposal site. Solid waste is trucked to the landfill, dumped, and periodically compacted and covered with earth. Liquid waste is discharged to unlined earth trenches until several million gallons of liquid have accumu lated. The trench is then filled with refuse and covered with a layer of earth.

These disposal activities provide a potential source of pollutants which could adversely affect the chemical quality of water in the area. The semi- arid climate (14 in or 360 mm of mean annual precipitation) and the low rol ling hills combine to produce minimal runoff in the small ephemeral streams that originate in or near the study area and constitute the surface-drainage network. As a result, the quality of ground water is of primary concern, for ground water is found at shallow depth in some locations and is the only reli able source of water in the area.

Purpose

The purpose of this study was: (1) To determine the direction of ground- water movement in the alluvial and bedrock aquifers underlying the area, (2) to evaluate the effects of the waste-disposal activities on the chemical qual ity of the ground water, and (3) to determine the need for future water-qual ity monitoring in the area.

The scarcity of existing wells in the study area required that additional observation wells be drilled. As shown on plate 1 and in table 1 (at back of report), 41 observation wells were installed at depths ranging from 4 to 248 feet (1 to 76 m). The tables in this report present pertinent data for thest, wells in addition to the 17 previously existing wells in the study area. The well-numbering system used in this study indicates the location of the well by quadrant, township, range, section, and position within the section, as illus trated in figure 2.

DIRECTION OF GROUND-WATER MOVEMENT

The determination of the direction of ground-water movement requires an understanding of the geology of the area before water-level measurements in wells can be properly interpreted to show the direction of movement. The di rection of movement in conjunction with estimates of the rate of ground-water movement provides a means of evaluating the potential effects of movement of degraded ground water.

The surficial geology of the area consists of two principal units: (1) Alluvium consisting of unconsolidated, poor- to moderately well-sorted clay, silt, sand, and gravel of Pleistocene and Holocene age with a maximum thick ness of about 25 feet (7.6 m); and (2) the undifferentiated Denver and Dawson Formations consisting of brown, dusky-yellow, and blue-gray mudstone with thin, lenticular beds of lignite and gray sandstone. The Denver and Dawson Formations are of Late Cretaceous and Paleocene age and extend from land sur face to a depth of 1,570 feet (478 m) in well SC 5-65- 5BDA (McConaghy and others, 1964). The mudstone units are dense, moderately consolidated, and show little evidence of joints or fracture cleavage. Lignite beds encountered dur ing drilling of observation wells did not yield measurable quantities of water to the wells. The sandstone beds are the only units capable of yielding meas urable quantities of water to the observation wells in the consolidated forma tions. The geologic sections (figs.3 and 4) show the relation of the alluvium and the sandstone and lignite in the upper part of the bedrock formations. The bedrock formations dip to the northwest at about 1 degree near the west edge of the study area and are relatively flat-lying in the remainder of the area.

The yield of most of the observation wells perforated in the alluvium was about 0.1 gallon per minute (0.4 L/min) with a few wells yielding as much as 10 gallons per minute (38 L/min). All the wells having higher yields are lo cated along Coal Creek, an area where field examination of drill cuttings in dicated the alluvium to be coarser, better sorted, and, therefore, more per meable. The wells with lower yields are due to the small saturated thickness, fine grain size, and poor sorting of most of the alluvial materials in the remainder of the area. Yields from about 200 feet (60 m) of hole drilled in the bedrock normally did not exceed 5 gallons per minute (19 L/min), although the sandstone encountered at a depth of 50 feet (15 m) in well SC 5-65- 6CAC2 yielded about 20 gallons per minute (80 L/min) during drilling.

Water-table contours for the alluvial aquifer (pi.1) indicate that ground water moves down the alluvial valleys in a direction controlled by the geology and the orientation of the valley. The general direction of movement is to the north or northwest.

When water-level measurements in wells tapping confined aquifers are used in contouring,the resulting map is termed a potentiometric-contour map (pi.2). The solid potentiometrie contours on plate 2 represent the elevation at which water stands in wells whose depths range from 100 to 350 feet (30 to 110 m). Wells of this depth are perforated in the upper part of the undifferentiated bedrock formations. A comparison of plates 1 and 2 indicates that the potentiometric surface in the upper part of the bedrock is generally 10 to 40 feet (3 to 10 m) below the water table in the alluvium. The potential thus exists for ground-water movement from the alluvium into the upper part of the bed rock. The general direction of ground-water movement in the upper part of the bedrock, as in the alluvium, is to the north.

Water-level measurements in wells perforated in the alluvium or the upper part of the bedrock indicate that only minor water-level changes have occurred in these zones from 1974 to 1976. However, 1974 water-level measurements in frequently pumped domestic wells (wells SC 4-65-28AAB and SC 4-65-30AAB, for example) perforated in the lower part of the bedrock formations are as much as 100 feet (30 m) below measurements made at the time the wells were drilled in 1971. In order to avoid considering the effects of localized water-level de clines around pumping wells, the potentiometric-contour map for the lower part of the bedrock is based on measurements made at the time each well was drilled. The dashed potentiometric contours on plate 2 are based on water-level meas urements in five wells ranging in depth from 570 to 1,570 feet (170 to 480 m) and represent the potentiometric surface in the lower part of the bedrock for mations. In this depth interval the direction of ground-water movement gener ally is to the west. The same direction of local movement occurs in aquifers at depths between 1,800 and 2,000 feet (550 and 610 m) as found by Romero (1976).

An unusual condition thus exists, in which ground water in the alluvium and the upper part of the bedrock formations moves to the north while ground water in the lower part of the bedrock formation moves to the west. This sug gests that the aquifers in the two depth intervals do not have good hydraulic connection. The divergence in the direction of ground-water movement coexists with large differences in head with depth in the formations. Near well SC 5- 65- 6CDA, for example, the elevation of the water table in the alluvium is about 40 feet (12 m) higher than the potentiometric surface in the upper part of the bedrock, and about 250 feet (76 m) higher than the potentiometric sur face in the lower part of the bedrock. By contrast, near well SC 4-65-28BDD the total difference between the elevation of the water table in the alluvium and the potentiometric surface in the lower part of the bedrock is about 60 feet (18 m). The vertical differences in head create a potential for downward movement of ground water in addition to the potential for lateral movement in dicated by the potentiometric-contour maps.

Both the rate and direction of ground-water movement are of prime concern in any study of ground-water contamination. In order to calculate the rate of ground-water movement, it is necessary to have data describing the ability of the saturated sediments to transmit water (hydraulic conductivity) and the volume of pore space in the sediments (porosity). These characteristics of the sediment are used in conjunction with the hydraulic gradient (slope of the

water table or potentiometric surface) to calculate the ground-water velocity by use of the equation:

V = f^ x 365,<P

where V = ground-water velocity, in feet per year, ^ = hydraulic conductivity, in feet per day, I = hydraulic gradient (dimensionless, feet per feet), and <f> = porosity (dimensionless).

Data on the hydrologic properties of the sediments in the study area are not available; consequently, the actual ground-water velocities in the area cannot be calculated. However, data describing the hydrologic character of the alluvium in sec. 28, T. 4 S., R. 67 W., and sees. 20 and 23, T. 5 S., R. 66 W., are available, as are data for the upper part of the bedrock formations in sec. 18, T. 4. S., R. 65 W. and sec. 24, T. 6 S., R. 66 W. (McConaghy and others, 1964). If these data are used in conjunction with the hydraulic grad ients in the study area, the rate of ground-water movement can be calculated for sediments of similar hydraulic conductivity and porosity in the study area. However, it is unknown whether or not the data describing the hydrolog ic character of the alluvium and bedrock outside the study area reflect the hydrologic character of the units in the study area. As a result of these un certainties, the velocities calculated using these data are considered to be general indications of the magnitude of ground-water velocities and not actual velocities in the study area.

The hydraulic conductivity of 10 samples from alluvium 2 to 9 miles (3 to 14 km) from the study area ranged from 8xlO~ 3 to 130 feet per day (2xlO~ 3 to 40 m/d) with a mean of 32 feet per day (10 m/d) (fig. 5). The mean porosity was 34.2 percent. When the hydraulic gradient (0.011) in the alluvium in the study area is used, the resulting lateral ground-water velocities range from 9.4xlO~2 to 1,500 feet per year (2.9xlO~2 to 460 m/yr) with a mean of 380 feet per year (120 m/yr). The ground-water velocities in the alluvium of Coal Creek are probably much higher than those in the other alluvial areas as are the yields of wells near Coal Creek. The hydraulic conductivity of six sam ples taken from the upper part of the bedrock formations 1 to 8 miles (2 to 13 km) from the study area range from 9.4xlO~ 5 to 8.7 feet per day (2.9xlO~ 5 to 2.7 m/d) with a mean of 2.8 feet per day (0.85 m/d). The mean porosity was 41.4 percent. Using the hydraulic gradient in the upper part of the bedrock in the study area (0.011), the lateral ground-water velocities were calculated to range from 9.IxlO"4 to 84 feet per year (2.8xlO~ 4 to 26 m/yr) with a mean of 27 feet per year (8.2 m/yr).

The rate of vertical ground-water movement is also of concern because of the head change with depth in the formations. The rate of vertical movement in saturated materials is primarily controlled by the stratum having the lowest vertical hydraulic conductivity and greatest thickness. If the siltstone in the upper part of the bedrock formations near the landfill is the stratum of lowest vertical hydraulic conductivity, the combined thickness of the stratum at well SC 5-65- 6DBC, for example, may be used to calculate the vertical hy draulic gradient. Data in tables 1, 2, and 3 (at back of report) indicate that

a head difference of 6.5 feet(2.0 m) exists across a zone about 160 feet(50 m) thick consisting primarily of siltstone. As in the previous calculations, the hydraulic conductivity and porosity of the bedrock in the study area are not known. If hydraulic properties comparable to those used for the lateral ve locity calculations are considered, the vertical hydraulic conductivity of the siltstone likely would be between the average and minimum horizontal hydraulic conductivity for the upper part of the bedrock. A vertical velocity of 0.58 foot per year (0.18 m/yr) is calculated by using a vertical hydraulic conduc tivity midway between the mean and minimum lateral hydraulic conductivity (1.6xlO~2 ft/d or 4.9xlO~ 3 m/d) and a porosity of 41.4 percent. However, if the vertical hydraulic conductivity was equal to the minimum lateral hydraulic conductivity (9.4xlO~ 5 ft/d or 2.9xlO~5 m/d), the vertical velocity would equal 3.4xlO~ 3 foot per year (l.QxlO" 3 m/yr).

If the average velocities are assumed to be representative of the general ground-water velocities to occur in the study area, the movement and possible effects of sources of ground-water degradation can be evaluated. If water in the upper part of the bedrock formations were degraded near the landfill, for example, it would require about 500 years for the degraded water to move 2.5 miles (4 km) from the landfill to the nearest domestic well (SC 4-65-30AAB). During this movement, the degraded water would be diluted by recharge of nondegraded water from the alluvium and would be further diluted by mixing with nondegraded water in the upper part of the bedrock formations. Unless the landfill becomes a long-term source of large quantities of leachate containing high concentrations of degrading constituents, it is unlikely that the degra dation would have a significant effect on the ground-water quality at well SC 4-65-30AAB in the foreseeable future.

The ground-water-flow path in the alluvium from the sludge disposal area in sec. 32, T. 4. S., R. 65 W., to domestic well SC 4-65-28BBC is about 1.6 miles (2.6 km). If the alluvium has an average hydraulic conductivity and po rosity of 32 feet per day (10 m/d) and 34.2 percent, it would require about 30 years for ground water to move from the east edge of sec. 32, T. 4, S., R. 65 W., to well SC 4-65-28BBC with the local hydraulic gradient of 7.6xlO" 3 . Un less the sludge-disposal area becomes a long-term source of a large quantity of leachate containing high concentrations of degrading constituents, the im pact on the water quality at well SC 4-65-28BBC would appear to be small.

EFFECT OF WASTE-DISPOSAL ACTIVITIES ON GROUND-WATER QUALITY

Land disposal of sludge began in the study area in 1969 and by 1976 application rates ranged from about 60 to 210 dry tons per acre (130 to 470 t/ha) in the areas where the sludge is plowed into the soil. About 34,000 dry tons (31,000 t) of sludge were buried in the burial site in sec. 9, T. 5 S., R. 65 W., between 1969 and 1970 (pi. 1). The current burial site in sec. 4, T. 5 S., R. 65 W., has received 3,000 to 4,000 tons (3,000 to 4,000 t) of sludge since 1973 (Don Grasmick, Metropolitan Denver Sewage Disposal District, written and oral commun., 1976). The chemical nature of the sludge varies considerably depending on the source of the sludge within the Metropolitan Denver Sewage Disposal District and the type of chemicals used to aid precip-

11

itation. The three principal types of sludge are not segregated in the dis posal area; as a result, the quality of the composite sludge is probably a combination of the three analyses shown in table 4 (at back of report). The composite sludge is high in calcium, total Kjeldahl nitrogen, ammonia, phospho rus, and the trace metals, cadmium, chromium, copper, lead, nickel, and zinc.

The landfill began operation in 1966 and by about 1972 liquid-waste trenches capable of holding in excess of 1 million gallons (4,000 m3 ) were be ing used (Jerry Bonello, City and County of Denver, oral commun., 1976). By 1975, between 1 and 2 million cubic yards (1 to 2 million m3 ) of compacted refuse had been buried at the site. The chemical quality of leachate moving through the buried refuse can be determined only by sampling a well drilled into the refuse, for no surface discharge of leachate occurs. Well SC 5-65- 6CDA, perforated at the base of the fill materials, provides the best avail able indication of the leachate quality (see table 5 at back of report). Wa ter from this well is particularly high in chloride, dissolved solids, sodium, iron, and manganese.

Analyses of water samples taken from a liquid waste trench at the land fill are shown in table 4 (at back of report) and indicate that the water con tains high concentrations of all the determined constituents with very high concentrations of sodium, potassium, and phenols.

Because ground-water quality was not monitored in the area prior to the beginning of disposal activities, the background water quality can be inferred only from the water quality in nearby wells in areas not likely to have been affected by the disposal activities. Four wells, by virtue of their location, are thought to be representative of the background water quality in the allu vium. Data from wells SC 4-65-30BDD, SC 4-65-31DDC, SC 5-65- 3ABB, and SC 5- 65- 9DDA indicate that, with the exception of iron and manganese concentra tions, the background water quality meets the U.S. Environmental Protection Agency's recommended drinking-water standards (1973) (table 6) and has dissolved-solids, sodium, chloride, and nitrate (as NOa) concentrations of about 550, 50, 11, and 0.1 mg/L, respectively. Wells SC 4-65-30BDA and SC 5-65- 8BCB are thought to be representative of background water quality in the upper part of the bedrock formations. This water meets the U.S. Environmental Pro tection Agency's recommended drinking-water standards (1973) and has dissolvedsolids, sodium, chloride, and nitrate (as NO3) concentrations of about 350, 100, 50, and 0.1 mg/L, respectively. Well SC 5-65- 5BDA is perforated in the lower part of the bedrock formations and is assumed to be representative of the background water quality in this zone. The water meets the U.S. Environ mental Protection Agency's recommended drinking-water standards (1973) and has dissolved-solids, sodium, chloride, and nitrate concentrations of about 200, 100, 5, and 0.2 mg/L, respectively. The ground water in both the alluvium and bedrock is of sodium bicarbonate type. The occurrence of water of lower dis solved-solids concentration at greater depth in the geologic section suggests that the primary source of the water at depth in the study area is not the downward movement of water from the alluvium but lateral movement from areas to the south or east. The water-quality data substantiate the data on the general direction and rates of ground-water movement which indicate that the movement in the area is primarily in the lateral rather than the vertical di rection.

From October 1974 to March 1976, about 200 water-quality samples were collected from wells perforated in the alluvium (tables 1 and 5 at back of report). A review of these data indicates that dissolved solids, sodium, chloride, and nitrate are better indicators of ground-water-quality degrada tion in the area than are the other determined constituents. Although con centrations of phenols and trace metals are known to be high in some of the waste, these constituents were not consistently detected in elevated concen trations near disposal areas. The high clay content of the sediments in the study area may be largely responsible for this, for these dissolved constitu ents are readily bound to clay minerals and their movement is thus inhibited.

Chloride and dissolved solids, by contrast, are highly mobile in the ground-water environment and are commonly excellent indicators of ground- water-quality degradation (Hughes and Robson, 1973; Palmquist and Sendlein,

13

1975; and Zanon, 1971). Because the temporal change in the concentration of dissolved constituents was not large (with the exception of well SC 5-65- 6CDA), mean concentrations calculated for each well over the 18-month sampling period are representative of the water quality commonly found in each well. By plotting the mean chloride and dissolved-solids concentrations for each well during the sampling period, a pattern of points is produced which has significance when the location of wells containing degraded and nondegraded ground water is known (fig. 6). It can be seen in figure 6 that the four wells representing background water quality in the alluvium (wells SC 4-65- 30BDD, SC 4-65-31DDC, SC 5-65- 3ABB, and SC 5-65- 9DDA) plot in the lower part of the graph while the well with degraded water in the landfill (well SC 5-65- 6CDA) plots in the extreme upper part of the graph. If the pattern of points is divided into three arbitrary regions, it can be seen in table 5 (at back of report) that wells in region 1 have water-quality characteristics similar to the background water quality in the area and are, therefore, least likely to have been affected by degradation from waste-disposal activities. Wells in region 3 have water-quality characteristics more similar to that of degraded ground water (table 5 at back of report) and are likely to have been affected by a source of degradation. Wells in region 2 yield water of intermediate quality with no clear indication of degradation.

There are readily apparent sources of ground-water degradation near each of the five wells in region 3. Well SC 5-65- 6CDA is located in the landfill refuse. Water from this well exceeds the U.S. Environmental Protection Agen cy's recommended drinking-water standards (1973) (table 6) for chloride, sulfate, iron, manganese, and lead. Wells SC 5-65- 4DBC and SC 5-65- 9ACD are located immediately downslope of two large areas used to bury sewage sludge (pi. 1). Leachate from the sludge could be affecting the ground-water quality near the two wells. The water quality is similar in both wells with nitrate, chloride, ammonia, and magnesium concentrations much higher than background concentrations, and sulfate and manganese concentrations exceeding U.S. Envi ronmental Protection Agency's recommended drinking-water standards (1973). Wells SC 565 4CAC and SC 46533CBC are equipped with windmills and are used to supply water for cattle. The overflow from the stock tanks forms stagnant manure-contaminated ponds which are thought to be the source of degradation in the nearby shallow wells. The water quality in these two wells is similar, both having much higher concentrations of nitrate, chloride, sulfate, and zinc than found in background samples, and sulfate in excess of the U.S. Environ mental Protection Agency's recommended drinking-water standards (1973). All but two of the wells used to monitor water quality in the alluvium, near areas where sludge is plowed into the soil, plot in region 1 of figure 6, which sug gests that none of the wells are strongly affected by the movement of water of degraded quality.

Wells in which the average nitrate concentration exceeded 0.3 mg/L (as NOs) during the sampling period are shown in table 7. The highest nitrate concentrations occur in wells downgradient from the two sludge-burial areas, near the landfill and near the stock-watering tanks, further indicating that ground-water-quality degradation is occurring in these areas. Nitrate con centrations ranging from 0.4 to 13 mg/L (as NOa) also occur in wells located downgradient from areas where sludge is plowed into the soil. These concen-

trations are above the 0.1-mg/L background concentration in the alluvium and are probably the result of the sludge-disposal practices in the area. The higher-than-background nitrate concentrations in water from wells SC 4-65- 28BBC and SC 4-65-29AAA are thought to be derived from agricultural sources near the wells.

Ground-water samples taken from 24 wells (table 5 at back of report) in February 1975 were analyzed for fecal coliform and fecal-streptococci bacte ria. None of the sampled wells had significant fecal coliform concentrations; however, fecal-streptococci concentrations ranging from 3 to 177 colonies per 100 milliliters of sample were found in 11 widely scattered wells. When these wells were resampled in April 1976, the analysis indicated negligible fecal- streptococci concentrations. In addition to samples for bacterial determina tions, eight wells were sampled for insecticides and industrial compounds and five wells were sampled for phenolic compounds. Polychlorinated-biphenols (PCB) were detected in wells SC 5-65- 4AAA and SC 5-65- 4DBC; the concentra tion was 0.2 ug/L. Phenolic compounds were detected in well SC 5-65- 6BDD; the concentration was 0.022 mg/L.

Between June 1975 and March 1976, about 60 water-quality samples were taken from 12 wells perforated in the upper part of the bedrock formation

16

(table 5 at back of report). During construction of all but three of these wells (SC44-65-30BDA, SC 5-65- 6BDD2, and SC 5-65- 9BCB), concrete grout used to seal the casing in the well bore inadvertently invaded the water-bearing materials and has had a pronounced effect on the chemical composition of water pumped from the wells. As a result, the pH, dissolved-solids, hardness, cal cium, carbonate, bicarbonate, hydroxide, and sulfate determinations for the affected wells are not representative of the water quality in the ground-water system. When the analyses for the wells unaffected by grout invasion are ex amined in conjunction with the unaffected parts of the analyses from grout- invaded wells, no clear pattern of water-quality degradation can be discerned. Although chloride concentrations are higher than background values in wells SC 4-65-32DBB2 and SC 4-65-32DBB3, as are total-Kjeldahl nitrogen concentra tions in wells SC 5-65- 4CAB2 and SC 5-65- 6CAC2 (table 5 at back of report), other dissolved constituents in these wells do not have markedly high concen trations. In addition, no insecticides or industrial compounds were detected in samples from wells SC 4-65-30BDA and SC 5-65- 6CAC1. If ground-water qual ity in the upper part of the bedrock is being affected by the waste-disposal activities in the area, the resulting changes in water quality are not dis cernible at this time (1976).

Water-quality analyses are available for three wells (SC 4-65-28AAB, SC 4-65-30AAB, and SC 5-65- 5BDA) perforated in the lower part of the bedrock formations. The water quality in wells SC 4-65-28AAB and SC 4-65-30AAB is similar to the background quality as represented by analysis from well SC 5- 65- 5BDA. The data indicate that the wells in the lower part of bedrock for mations show no effect of the waste-disposal activities in the area.

NEED FOR FURTHER WATER-QUALITY MONITORING

The basic purpose of a water-quality monitoring program in this area would be to record the effect of the waste-disposal activities on the water quality in order to help assure that any adverse effects do not exceed accept able limits. As of 1976, both the landfill and the sludge-burial areas are sources of only minor ground-water-quality degradation. However, the volume of leachate produced by these sources will likely increase in the future, as more material is deposited and the surface areas of the sites expand. In creased volumes of leachate could produce more rapid and widespread deterio ration in ground-water quality and increase the need for water-quality moni toring. Because of the slow rates of ground-water movement to be expected in •this area, monitoring would require only infrequent sampling of ground-water quality.

The landfill and the associated liquid-disposal trenches are of first- order concern in a water-quality-monitoring program because of the large vol ume of material handled and the lack of control over the type of materials that may be dumped. It is suggested that ground-water-quality monitoring near the landfill consist of sampling all the wells in sec. 6, T. 5 S., R. 65 W., twice a year and analyzing the samples for dissolved solids, sodium, chloride, nitrate, trace metals, and phenolic compounds. Although surface runoff from part of the landfill is presently intercepted by holding ponds, no means exist

17

to control the runoff from the entire landfill. Under present conditions, a spill resulting from the failure of a liquid-disposal trench could result in a slug of contaminated liquid which would enter the surface-drainage network and could contaminate riparian land and ground water for many miles downstream. If an earthen dam were constructed near well SC 5-65- 6ABC, surface runoff or accidental spills originating anywhere in the landfill could be contained and the resulting pool and local ground water could be monitored, if a potential for ground-water degradation was found to exist.

Less frequent water-quality monitoring would be needed near sludge-dis posal areas because of the lesser potential for ground-water degradation from these areas. Sampling the wells on an annual basis in the spring of each year is suggested to monitor the movement of degraded water. The suggested moni toring program could be achieved by sampling all the wells near the sludge- burial areas and wells SC 4-65-30DCD, SC 4-65-31DBB, SC 4-65-31CBA, SC 4-65- 32ADA, SC 4-65-32BAB, SC 4-65-33BAB1, SC 4-65-33CBC, SC 5-65- 4AAA2, and SC 5- 65- 6ABC near the plowed disposal fields. Analysis would include ammonia, chloride, zinc, magnesium, sodium, and dissolved solids. Monitoring near the sludge-disposal areas and the landfill would be needed for an indefinite peri od of time beyond the end of the disposal activities to assure that further leaching of the buried material would not contribute to the degradation of the ground water.

SUMMARY

As a result of this study it has been determined that the direction of ground-water movement in the alluvium and upper part of the bedrock formations generally is to the north while movement in the lower part of the bedrock for mations generally is to the west. Calculated rates of ground-water movement, using assumed values for hydraulic conductivity and porosity and the hydraulic gradients in the study area, indicate that the mean-lateral velocity in the alluvium is 380 feet per year (120 m/yr) and is 27 feet per year (8.2 m/yr) in the upper part of the bedrock formations. The calculated rate of vertical movement was 0.58 feet per year (0.18 m/yr) in the upper part of the bedrock formations. Data on both the direction and the rate of ground-water movement indicate that lateral movement is predominant with minimal vertical ground- water movement.

Sampling of wells perforated in the alluvium, the upper part of the bed rock, and lower part of the bedrock indicated that water of better general quality is found in the deeper formations in the area. This suggests that the primary source of the water at depth in the area is not the downward movement of water from the alluvium but lateral movement from areas to the south and east.

Five wells perforated in alluvial materials were found to have water of markedly degraded quality. One well is perforated at the base of buried re fuse in the landfill. Two other wells are located immediately downslope of two sludge-burial areas. The final two wells are used to water stock along Senac Creek. The degraded water in these wells may be due to the stock-tank

18

overflow which forms nearby stagnant manure-contaminated ponds. Samples from most of the wells below the plowed disposal fields indicated that the water in the alluvium in these areas had nitrate concentrations (as NOs) ranging from 0.4 to 13 mg/L. The concentrations are higher than the background nitrate con centration (0.1 mg/L) and are probably due to the sludge-disposal activities in the adjacent fields. Other wells in the alluvium and wells perforated in the upper part of the bedrock formations show no discernible effects of water- quality degradation produced by the waste-disposal activities in the area. Wells perforated in the lower part of the bedrock formations show no effects of the waste-disposal activities.

Because of continuing waste-disposal activities, continued water-quality monitoring is needed to determine the effects of the waste disposal on the quality of ground water, the only source of usable water in the area. It is suggested that all wells near the landfill be sampled twice a year with anal ysis for dissolved solids, sodium chloride, nitrate, trace metals, and phe nolic compounds, and wells near the sludge-disposal areas be sampled on an annual basis with analysis for nitrate, ammonia, chloride, zinc, magnesium, sodium, and dissolved solids.

Table 5.—Chemical analyses of water from wells

The following table consists of records for 53 wells. The table format consists of six pages of data for each group of six to nine wells. The first page for each group contains the local well number for each well in the group. On each of the five subsequent pages for each group, the date of sample is used to identify the wells.

Appropriate headnotes for the table are: Analytical results in milli grams per liter (MG/L) or in micrograms per liter (UG/L),as indicated. Dashes (—) indicate constituent for*which no analysis was made. Constituents with concentrations below the detection limit of the analytical procedure are indi cated by ND.
