Abstract 

Since late 1993, Metro Wastewater Reclamation District of Denver (Metro District, MWRD), a 

large wastewater treatment plant in Denver, Colorado, has applied Grade I, Class B biosolids to about 52,000 

acres of nonirrigated farmland and rangeland near Deer Trail, Colorado, USA. In cooperation with the Metro 

District in 1993, the U.S. Geological Survey (USGS) began monitoring groundwater at part of this site. In 

1999, the USGS began a more comprehensive monitoring study of the entire site to address stakeholder 

concerns about the potential chemical effects of biosolids applications to water, soil, and vegetation. This 

more comprehensive monitoring program has recently been extended through 2010. Monitoring components 

of the more comprehensive study include biosolids collected at the wastewater treatment plant, soil, crops, 

dust, alluvial and bedrock groundwater, and stream bed sediment. Soils for this study were defined as the 

plow zone of the dry land agricultural fields—the top twelve inches of the soil column. This report presents 

analytical results for the soil samples collected at the Metro District farm land near Deer Trail, Colorado, 

during three separate sampling events during 1999, 2000, and 2002. Soil samples taken in 1999 were to be a 

representation of the original baseline of the agricultural soils prior to any biosolids application. The soil 

samples taken in 2000 represent the soils after one application of biosolids to the middle field at each site and 

those taken in 2002 represent the soils after two applications. There have been no biosolids applied to any of 

the four control fields. The next soil sampling is scheduled for the spring of 2010. 

Priority parameters for biosolids identified by the stakeholders and also regulated by Colorado when 

used as an agricultural soil amendment include the total concentrations of nine trace elements (arsenic, 

cadmium, copper, lead, mercury, molybdenum, nickel, selenium, and zinc), plutonium isotopes, and gross 

alpha and beta activity (Colorado Department of Public Health and Environment, Hazardous Materials and 

Waste Management Division, 1997; Colorado Department of Public Health and Environment,1998; U.S. 

Environmental Protection Agency, 1993). Since these were the identified priority parameters for the 

biosolids, the soils have the same set of priority parameters. Although the composite soils’ priority analytes 

have been reported earlier to Metro District, the remaining elemental datasets for both the composite soils 

samples and selected fields’ individual subsamples’ data are presented here for the first time. More 

information about the other monitoring components is presented elsewhere in the literature 

(http://co.water.usgs.gov/projects/CO406/CO406.html). 

In general, the objective of each component of the study was to determine whether concentrations 

of priority parameters (1) were higher than regulatory limits, (2) were increasing with time, and(or) (3) were 

significantly higher in biosolids-applied areas than in a similar farmed area where biosolids were not applied. 

The method chosen for sampling the soils proved to be an efficient and reliable representation of the 

average composition of each field. This was shown by analyzing individual subsamples, averaging the 

resulting values, and then comparing the values to the composited samples’ values. The soil chemistry 

shows distinct differences between the two sites, most likely due to the different underlying parent material. 

Biosolids data were used to compile an inorganic-chemical biosolids signature that can be 

contrasted with the geochemical signature of the agricultural soils for this site. The biosolids signature and 

an understanding of the geology and hydrology of the site can be used to separate biosolids effects from 

natural geochemical effects. Elements of particular interest for a biosolids signature after application in the 

soils include bismuth, copper, silver, mercury, and phosphorus. This signature is due to the large difference 

between the applied biosolids and the original soil content of these elements.

Introduction 

Since 1993, the Metro Wastewater Reclamation District of Denver (Metro District) has been 

applying biosolids from the Denver metropolitan area to their property near Deer Trail, Colorado (fig.1), as 

an agricultural soil amendment. The biosolids are applied to nonirrigated farmland according to agronomic 

loading rates using broadcast technology.

In 1999, the Metro District property, known as the METROGRO Farm, encompassed about 81 mi2

(52,000 acres) of farmland in Arapahoe and Elbert counties, Colorado. The Metro District property and 

surrounding private property are herein referred to as “the study area.” 

Figure 1. Metro Wastewater Reclamation District of Denver (Metro District) biosolids application farm and study 

area location. 

Soils in the study area generally are sandy or loamy on flood plains and stream terraces, clayey to 

loamy on gently sloping to rolling uplands, and sandy and shaley on steeper uplands. About one-half of the 

Metro District property is farmed; the remaining is rangeland with some pasture. Land use within the rest of 

2
the study area during 1993 through 2008 mostly was rangeland or pasture with some cropland. Farmland in 

the study area is not irrigated. Figures 2a and 2b depict the typical land use of the study area. Biosolids 

were applied to the land surface of the Metro District property as an agricultural soil amendment, and the 

primary crop was wheat. Figure 3 shows a typical example of what fresh biosolids (the darker colored 

patches with the white arrows) look like on the landscape after a single broadcast application.

The main questions to be addressed in soil sampling include: How does the application of biosolids 

affect soil chemistry? Is there short-term and(or) long-term buildup of metals and(or) radioactivity caused 

by the application of biosolids? Is this buildup, if any, within acceptable limits for soil quality as established 

by Federal and state agencies? 

This report presents all analytical data collected to date for the composited soil samples and selected 

individual subsamples. 

Purpose of Monitoring Soils 

 Biosolids are known to contain elevated concentrations of certain heavy metals. The use of 

biosolids as an agricultural soil amendment has caused some level of concern among the citizens of 

Arapahoe and Elbert counties regarding the short-term and long-term impact on soil quality. Biosolids data 

are presented elsewhere for this study (Crock and others, 2008a, b). The purpose of monitoring the 

composition of soil is to establish an independent geochemical database on the composition of soil before the 

application of biosolids, and then to establish a database after the application. These data will enable 

recognition and quantification of any change in soil composition caused by the application of biosolids to 

agricultural soils or by other natural or human-induced processes. 

Approach for Monitoring Soils 

 In August 1999, the USGS began monitoring soils on two sites, one site on MWRD property in 

Arapahoe County and one site on MWRD property in Elbert County. The sites were monitored for priority 

parameters consisting of (1) nine trace elements for which biosolids are regulated (Colorado Department of 

Public Health and Environment, Hazardous Materials and Waste Management Division, 1997): arsenic, 

cadmium, copper, lead, mercury, molybdenum, nickel, selenium, and zinc, and (2) plutonium, and gross 

alpha and beta activity. The radioactivity analyses were included in response to public concerns that 

biosolids radioactivity could increase from the transfer of water from the Lowry Landfill Superfund site to 

the MWRD. Soil samples were collected once in (1999) before the application of biosolids to monitoring 

sites, and the data were reported by Stevens and others (2003). The 1999 sampling occurred before biosolids 

were applied. The study continued through two cycles of biosolids application and crop harvest with soil 

sampling done shortly after each harvest. Soils were sampled again in 2000 after one biosolids application to 

the middle field of each site and again in 2002 after a second biosolids application. Fields that received 

biosolids applications were monitored along with fields that received no biosolids, which represented 

reference conditions for comparison. These data are reported by Yager and others (2004c). The next soil 

sampling is scheduled for the spring of 2010, after five applications of biosolids have been made to the 

middle fields of each county site. 

Table 1 lists the fields’ location. Figure 4 shows the stylized layout and measurements for each test 

site. Figures 5 and 6 show the Elbert and Arapahoe County monitoring fields’ locations, respectively, in 

greater detail than figure 1. 

Each of the two soil-monitoring sites consisted of three 20-acre (933 ft x 933 ft) fields separated by 

100-foot buffer zones (fig. 4). Biosolids were applied to the center 20-acre field at each site after the initial 

soil sampling and again after each harvest. The other two 20-acre fields at each site never had biosolids 

applied and were used as “control” fields to determine the natural variability of soil composition for the 

duration of the study. All three 20-acre fields at each site were farmed in a similar way as the rest of the 

MWRD property and had crops planted and harvested. 

The sampling protocol was designed to provide data to address the following issues: How does the 

application of biosolids affect soil chemistry within the top 12 inches of the surface? Is there short-term 

and(or) long-term buildup of metals and(or) radioactivity in the top 12 inches of soil caused by the 

application of biosolids? Is this buildup, if any, within acceptable limits for soil quality as established by 

Federal and state agencies? To answer these questions, an average elemental composition of the entire 

field’s plow zone is required. A single composite sample made from multiple subsamples taken on a grid 

pattern provides the “average” composition of soil in a given field at a given time. Spatial variability of an 

element of interest within a given field cannot be determined by this sampling design. This approach does 

not allow us to distinguish different geochemical characteristics of multiple soil types within a given field. 

4
Analyzing the individual subsamples will provide an estimation of a field’s local variability—a preliminary 

geochemical map. 

A standard soil auger was used to collect samples to a depth of 12 inches according to a systematic 

grid pattern (figs. 4, 7a, b). Either 30 or 36 subsamples were collected for each of the 20-acre fields during 

each sampling event. After air drying, disaggregating, sieving to less-than-2 mm, and grinding to less 

than150 μm, splits of the subsamples were composited into one sample for chemical analysis. Complete 

details on site selection, dates of sample collection, sample-collection protocols, analytical methods, and 

quality-assurance protocols are described by Stevens and others (2003) and Yager and others (2004a, b, c, 

and d).

Methodology 

Sampling Methods 

 The sampling protocol was designed to determine the average composition of the top 12 inches of 

soil in each of the six 20-acre fields. In order to address this issue, soil samples were collected with a 

standard soil auger to a depth of 12 inches according to a systematic grid pattern. On each of the two fields 

to which biosolids would be applied, 36 subsamples were collected on approximately 133-foot centers. A 

similar grid was used in sampling the southern “control” field on the Arapahoe County site resulting in 36 

subsamples. For the remaining three “control” fields, 30 subsamples were collected at approximately 155-

foot centers. The subsamples in each field were composited into one sample for chemical analysis 

representing the entire 20-acre field. All the subsamples were dried at ambient temperature under forced air 

in the USGS laboratories in Lakewood, CO. 

Analytical Methods 

Each of the dried subsamples was disaggregated, sieved to less than 2 mm, and ground to less than 

150 μm. Splits of each subsample were taken for archival storage. A 30-gram aliquot of each subsample 

from each of the six individual fields was taken and then composited for a given 20-acre field to produce six 

composite samples representing each of the six 20-acre fields. This insures that each of the subsamples is 

equally represented for the final composite soil samples. These six composite soil samples were analyzed by 

the methods shown in table 2. For selected fields from each year, the individual subsamples that were used 

to make the composited samples were also analyzed by the methods given in table 2. Analyzing these 

individual samples gives information on the local variability of each field’s geochemistry and also is an 

indicator of how well the composited samples represent the field’s overall composition.

Discussion and Results 

The analytical results shown in table 3 represent the prebiosolids application geochemical baseline 

for each of the six fields sampled. These results point out that the soils sampled in Arapahoe County have 

somewhat different geochemical characteristics that those sampled in Elbert County. The Elbert County 

soils show higher concentrations of most of the metals analyzed. This may be related to the higher clay 

content that we observed while sampling the Elbert County soils. Clay minerals tend to adsorb metal ions 

from solution, and this process may have led to the slight enrichment of metals in the Elbert County site. It 

is interesting to note that the arsenic content of soils in both counties is actually higher than the arsenic 

content of biosolids (Crock and others, 2008a, b). Table 4 lists the analytical results for the 2000 composite 

samples after one application of biosolids. Table 5 lists the analytical results for the 2002 composite samples 

after two applications of biosolids. Tables 6, 7, and 8 list the analytical results for the individual subsamples 

from the Arapahoe County Middle Field for the 1999, 2000, and 2002 samplings, respectively. Also give in 

tables 6, 7, and 8 are the soil composite values for comparison. Tables 9 through 14 list the analytical results 

for the individual subsamples from the various Elbert County fields over the three sampling events. The 

corresponding soil composite values are also given for comparison. Table 15 lists the results for gross alpha 

and beta and the plutonium isotopes for each of the three years’ composite soil samples for each field. All 

soil samples were consistently below the reported detection limits for all of the plutonium isotopes. The 

highly variable gross alpha and beta data are of questionable use. The regulatory limits for these analytes 

have since been dropped by the State of Colorado. 

In order to evaluate the potential effects of biosolids on soils near Deer Trail, Colorado, the natural 

geochemical variability associated with estimating the average composition of soil in the 20-acre monitoring 

fields must be ascertained. This natural variability is caused by (1) the heterogeneous nature of the soil and 

by (2) the uncertainty associated with laboratory chemical analyses. 

8
Soil exhibits two primary types of heterogeneity. The first type is called “constitutional 

heterogeneity” (Pitard, 1993) and refers to the difference in chemical composition among the particles that 

make up the soil. The second type is called “distribution heterogeneity” (Pitard, 1993) and refers to the 

uneven distribution of the soil particles throughout each monitoring field. The variability caused by these 

types of heterogeneity is generally much larger than the variability caused by laboratory uncertainty, 

although for some elements, the laboratory variability may exceed the sampling variability (Crock and 

others, 1992, 1994; Severson and others, 1990; Stewart and others, 1993). In order to state with confidence 

that the composition of soil in the biosolids-applied field is being affected by biosolids, the change in 

composition for a given element must exceed the natural variability for that element as determined in the 

control fields. 

The geochemical data from the first soil sampling in 1999, prior to any biosolids application to the 

monitoring sites, showed a significant difference in the composition of soils collected from the Arapahoe 

County site in comparison to those collected from the Elbert County site (Stevens and others, 2003). The 

Elbert County soils generally showed higher concentrations of trace elements than Arapahoe County soils 

(for example, 14.1 compared to. 6.7 ppm As, 19.3 compared to 13.9 ppm Cu, 28 compared to 20 ppm Ni, 27 

compared to 20 ppm Pb, and 100 compared to 69 ppm Zn [comparing the 1999 middle fields of each site, 

ICP–MS data]). This was confirmed in data from the two subsequent sampling events (Yager and others, 

2004c), and is likely related to the observed higher clay content of the Elbert County soils, which, in turn, is 

related to the parent material of the soil. Most of the soils at the Elbert County site belong to the Renohill 

Series, which developed in material weathered from shale (Larsen and others, 1966). Most of the Arapahoe 

County site contains soils from the Baca Series, which has a larger component of sandstone in its parent 

material (Larsen and Brown, 1971). It is well documented in the geochemical literature that shales contain 

higher concentration of trace elements than sandstones (Rose and others, 1979) and, thus, the Elbert County 

soils have a higher content of these elements than the Arapahoe County soils. 

It is possible to perform simple calculations that will enable us to determine if any measurable 

impact to the soils should have been expected from two applications of biosolids and also to determine how 

many applications it would take before we could observe a measurable difference in composition of the soil. 

These calculations assume that all the applied biosolids remain within the top 12 inches of soil. In other 

words, it is assumed there is no physical transport by wind or water, or chemical transport beyond the 

boundaries of the monitoring field or to a depth greater than 12 inches. Of the nine regulated trace elements, 

copper shows the largest difference in concentration between the biosolids (average copper concentration = 

620 mg/kg) and soils in the control fields (16 mg/kg average for Arapahoe County control fields) (table 3). 

Using the biosolids application rate of 1.14 tons (1,034 kg) per acre used during 2002 for the Arapahoe 

County site (B. Patterson, MWRD, written communication, February 25, 2004), we may calculate the 

number of kilograms of copper applied to one of the 20-acre fields as follows: 

(1) (1,034 kg biosolids/acre) x (20 acres) x 620 mg copper/kg biosolids) = 1.28 x 107

 mg copper 

applied to one 20-acre field 

We now need to know the total number of kilograms of soil contained in the top 12 inches (30.5 cm) of a 20-

acre (284 m x 284 m = 80,656 square meters) field. To calculate this number, we must know the density of 

the soil. The density was measured in the field by the USGS and was found to be approximately 1.4 grams 

per cubic centimeter. This value was confirmed by bulk density information for soils of Arapahoe County 

given on the Web site of the Natural Resources Conservation Service 

(http://ssldata.nrcs.usda.gov/querypage.asp, accessed on July 1, 2004). We can now make the following 

calculation: 

(2) (80,656 m2

) x (10,000 cm2/m2) x (30.5 cm) x (1.4 gm/cm3) x (1 kg/1,000 gm) = 3.44 x 107 kg of 

soil in the top 12 inches of a 20-acre field 

We can now divide the results of calculation (1) by calculation (2) to obtain the concentration of copper in 

the top 12 inches of soil as a result of applying biosolids at a rate of 1.14 tons/acre. 

(3) (1.28 x 107

 mg copper) / (3.44 x 107 kg soil) = 0.37 mg copper/kg soil. 

9
This indicates that one application of biosolids at a rate of 1.14 tons/acre increases the concentration of 

copper in the top 12 inches of soil by only 0.37 mg/kg. Given that the average copper content of soils on the 

Arapahoe County site is approximately 16 mg/kg, this is only a 2 percent increase. Such a small increase is 

beyond our capability of measuring with any degree of confidence. Table 3 shows that the natural variability 

for copper in soils from the Arapahoe County control fields is plus or minus 5 mg/kg. It would take about 14 

applications of biosolids at the above application rate, with an increase of 0.37 mg/kg with each application, 

to exceed this 5 mg/kg uncertainty. Assuming that the application rate for biosolids remained constant at 

1.14 tons/acre and that applications took place every other year, then it would take about 28 years before the 

copper content increased to the point where the natural variability could begin to be ruled out. For those 

elements whose concentrations in biosolids are not so drastically different from their concentration in soil, it 

would take considerably longer before the effects of biosolids application could be measured beyond the 

natural variability.
