Terracon Project No. 13207110
Dear Mr. Schindel:
Terracon Consultants, Inc. (Terracon) appreciates the opportunity to submit this proposal to
conduct municipal water well sampling activities for the referenced site. An outline of the project,
Terracon's scope of services, including schedule and compensation are provided in the following
sections.
1.0 PROJECT INFORMATION
Based on the results of the risk -based receptor survey performed as a part of the Tier 2
Assessment, seven public supply water wells were identified within one mile of the site resulting
in a preliminary site classification of "High Risk". In order for the site to achieve a No Action
Required classification, Terracon recommends that the seven identified public supply wells be
researched to determine if they in deed still exist. If present, Terracon recommends a "tap" water
sample be collected from each well location. Geothermal wells or wells used for other
heating/cooling purposes are not required to be evaluated per guidance regardless if owned by a
municipality.
This proposal presents the estimated fees for researching the water wells and collecting "tap"
water samples from each well that is actually used for potable water, food production, or other
type of human consumption.

2.0 SCOPE OF SERVICES
lrerracon
Terracon has a 100% commitment to the safety of all its employees. As such, and in accordance
with our Incident and Injury Free® safety culture, Terracon will update our safety plan for use by
our personnel during field services. Prior to commencement of on -site activities, Terracon will hold
a meeting to review health and safety needs for this specific project. At this time, we anticipate
performing fieldwork in a United States Environmental Protection Agency (USEPA) Level D work
uniform consisting of hard hats, safety glasses, protective gloves, and steel -toed boots. It may
become necessary to upgrade this level of protection, at additional cost, during sampling activities
in the event that petroleum or chemical constituents are encountered in soils or groundwater that
present an increased risk for personal exposure.
2.1 Municipal Water Well Research and Sampling
Terracon will research the seven identified public supply wells with the City of
Waterloo and Black Hawk County Environmental Health Department to obtain
information relevant to the existence of the identified wells. If it is determined that a
well is not present, the Tier 2 Report will be revised to indicate the obtained
information and well status. A photo log for the for the supposed / reported locations
will also be prepared.
If the wells are present, Terracon will collect a "tap" water sample from each well.
The sample will be collected from a faucet or spigot after allowing the water to run
for approximately five minutes to purge water from the plumbing and pipes and
draw fresh water in from the water supply. A sampling location ahead of any water
treatment will be selected if possible.
The samples will be collected in laboratory provided containers and submitted on ice
to a State of Iowa certified laboratory under standard chain of custody protocols for
analysis of benzene, toluene, ethylbenzene, and xylenes (BTEX) and methyl tert-
butyl ether (MTBE) by Iowa Method OA-1 and total extractable hydrocarbons (TEH)
by Iowa Method OA-2.
The results of the sampling will be incorporated into the Tier 2 evaluation.
Additional Services Beyond Base Services
The scope of this proposal is based upon IDNR guidance and preliminary Tier 2 evaluation.
Fees for the above services are listed in Table 1 and are based on mobilization from Terracon's
Cedar Falls, Iowa office. Please note that the table is not all-inclusive. If, as a result of these
services, additional work is required outside the scope of this proposal and beyond those outlined

and the information collected as discussed in this proposal. Please note that we do not warrant
database or third -party information or regulatory agency information used in the compilation of
reports.

evaluate the nature of adverse environmental impact associated with the identified chemical
release under 1996 changes to Iowa Administrative Code 455B, Chapter 135. The evaluation
does not constitute a complete risk assessment consistent with the definitions and protocols of
CERCLA. The client should recognize that no guarantee can be made that the RBCA evaluation
will result in either a no action or reduced remedial recommendation.
The limitations herein must be considered when the user of this report formulates opinions as to
risks associated with the site. No warranties, express or implied, are intended or made.
3.0 COMPENSATION
Fees for services specific to this site are $2,740 and are detailed in the attached Table 1. Interim
