1.0 INTRODUCTION
1.1 Site Description
Site Name Conifer & Redwood Parcel
Site Location/Address S/W/C of Conifer & Redwood Intersection, Fort Collins, CO
General Site
Description
Undeveloped 31 acre tract of land
A topographic map is included as Figure 1, and a site plan is included as Figure 2 of Appendix
A.
1.2 Scope of Work
Terracon Consultants, Inc. (Terracon) conducted a Limited Site Investigation (LSI) at the Conifer
and Redwood site in Fort Collins, Colorado. At your request, Terracon’s LSI was undertaken in
response to the results of Terracon’s Environmental Site Assessment (ESA Report
No.20117733 dated October 31, 2011) which identified the following potential recognized
environmental condition (REC):
The Auto Body Specialists facility upgradient of the site was identified as a REC based
on the reported use of solvents and body shop processes.
The objective of the LSI was to evaluate the groundwater for Volatile Organic Compounds
(VOCs). Terracon was not requested to conduct additional assessment of soils at the site.
Terracon’s LSI was conducted in accordance with our Proposal No. P20110256 dated
November 7, 2011.

1.3 Standard of Care
Terracon’s services were performed in a manner consistent with generally accepted practices of
the profession undertaken in similar studies in the same geographical area during the same
time period. Terracon makes no warranties, either express or implied, regarding the findings,
conclusions or recommendations. Please note that Terracon does not warrant the work of
laboratories, regulatory agencies or other third parties supplying information used in the
preparation of the report. These LSI services were performed in accordance with the scope of
work agreed with you, our client, as reflected in our proposal and were not restricted by ASTM
E1903-97.
1.4 Additional Scope Limitations
Findings, conclusions and recommendations resulting from these services are based upon
information derived from the on-site activities and other services performed under this scope of
work; such information is subject to change over time. Certain indicators of the presence of
hazardous substances, petroleum products, or other constituents may have been latent,
inaccessible, unobservable, non-detectable or not present during these services, and we cannot
represent that the site contains no hazardous substances, toxic materials, petroleum products,
or other latent conditions beyond those identified during this LSI. Subsurface conditions may
vary from those encountered at specific borings or wells or during other surveys, tests,
assessments, investigations or exploratory services; the data, interpretations, findings, and our
recommendations are based solely upon data obtained at the time and within the scope of these
services.
1.5 Reliance
This report has been prepared for the exclusive use of Owen Consulting Group, Inc. and any
parent, subsidiary or affiliate company thereof, and any authorization for use or reliance by any
other party (except a governmental entity having jurisdiction over the site) is prohibited without
the express written authorization of Owen Consulting Group, Inc. and Terracon. Any
unauthorized distribution or reuse is at the client’s sole risk. Notwithstanding the foregoing,
reliance by authorized parties will be subject to the terms, conditions and limitations stated in
the proposal, LSI report, and Terracon’s Terms and Conditions. The limitation of liability defined
in the terms and conditions is the aggregate limit of Terracon’s liability to the client and all
relying parties unless otherwise agreed in writing.
2.0 FIELD ACTIVITIES
Terracon’s field activities were conducted on November 14, 2011, by Janine Mushock and Craig
Nelson, Terracon environmental professionals. The approved scope of work included surveying
the top of well casing elevations for three existing piezometers that we understand were
previously installed for geotechnical observations; measuring depth to water, purging wells of

minimum of three well casing volumes per well and collecting groundwater samples from the
three existing piezometers (B-1, B-3, and B-5) on site. Table 1 included in Appendix B indicates
top of well casing and groundwater elevations.
Figure 1 presents the general boundaries and topography of the site on portions of the USGS
topographic quadrangle map of Fort Collins, Colorado (Appendix A). Figure 2 is a site plan that
indicates the approximate location of the piezometers in relation to the pertinent structures and
general site boundaries (Appendix A).
2.1 Groundwater Sampling
After purging each piezometer, one groundwater sample was collected from each well using a
new disposable bailer. Depth to groundwater was observed at 7.85 feet below top of casing in
B-1, 8.70 feet in B-3 and 6.85 feet in B-5. Groundwater flow is estimated from groundwater
depths to be towards the northwest.
Groundwater samples were collected and placed in laboratory prepared glassware and placed
on ice in a cooler. The sample coolers and completed chain-of-custody forms were relinquished
to ESC’s analytical laboratory in Mt. Juliet, TN for standard turnaround.
3.0 LABORATORY ANALYTICAL METHODS
The groundwater samples collected were analyzed for VOCs using EPA Method 8260.
Laboratory data sheets and the executed chain-of-custody form and laboratory data sheets are
provided in Appendix C.
4.0 DATA EVALUATION
4.1 Groundwater Samples
Groundwater samples collected from B-1, B-3 and B-5 did not contain VOCs at concentrations
above laboratory detection limits.
5.0 FINDINGS AND RECOMMENDATIONS
VOCs were not detected above laboratory detection limits in the samples collected from the
three piezometers. No additional investigation is recommended at this time.

Qualifier Meaning
__________________ _______________________________________________________________________________
J3 The associated batch QC was outside the established quality control range
for precision.
J4 The associated batch QC was outside the established quality control range
for accuracy.
J6 The sample matrix interfered with the ability to make any accurate
determination; spike value is low
Qualifier Report Information
ESC utilizes sample and result qualifiers as set forth by the EPA Contract Laboratory Program and
as required by most certifying bodies including NELAC. In addition to the EPA qualifiers adopted
by ESC, we have implemented ESC qualifiers to provide more information pertaining to our analytical
results. Each qualifier is designated in the qualifier explanation as either EPA or ESC.
Data qualifiers are intended to provide the ESC client with more detailed information concerning
the potential bias of reported data. Because of the wide range of constituents and variety of
matrices incorporated by most EPA methods,it is common for some compounds to fall outside of
established ranges. These exceptions are evaluated and all reported data is valid and useable
"unless qualified as 'R' (Rejected)."
Definitions
Accuracy - The relationship of the observed value of a known sample to the
true value of a known sample. Represented by percent recovery and
relevant to samples such as: control samples, matrix spike recoveries,
surrogate recoveries, etc.
Precision - The agreement between a set of samples or between duplicate samples.
Relates to how close together the results are and is represented by
Relative Percent Differrence.
Surrogate - Organic compounds that are similar in chemical composition, extraction,
and chromotography to analytes of interest. The surrogates are used to
determine the probable response of the group of analytes that are chem-
ically related to the surrogate compound. Surrogates are added to the
sample and carried through all stages of preparation and analyses.
TIC - Tentatively Identified Compound: Compounds detected in samples that are
not target compounds, internal standards, system monitoring compounds,
or surrogates.
