SCOPE OF SERVICES: The City of Bozeman has proceeded with preparing for and conducting
indoor air sampling in homes within the area (neighborhood) of its soil gas investigation. The soil
gas investigation consisted of the installation of soil gas monitoring probes and gas sample

neighborhood. Tetra Tech has also been involved in public outreach as part of their sampling
activities. The costs included in this task order are estimates as this investigation is ongoing. This

Task 1 consists of preparing for and conducting air sampling in residential structures in the
neighborhood. The air sampling consists of first, conducting a home survey to determine home
chemical products to be removed (including automobiles and fuel storage containers from the
home and garage). Public outreach and communication of the project has been conducted while
Tetra Tech has completed the home survey. Second, two more visits are conducted to drop off
and pick up the air sampling equipment. There are 26 homes in the neighborhood. It is
anticipated that all 26 homes will have home surveys and air sampling conducted. Tetra Tech staff
in both the Bozeman and Helena offices have been and will continue to be utilized.
Task 2 Reporting and Project Management
Task 2 consists of data management, report preparation, and project management. Data
management consists of handling of laboratory results of air sampling, communication of those
results, and organization of results into a database. Report preparation will consist of providing
one or more reports to the City of Bozeman summarizing the results of the indoor air sampling.
Project management consists of scheduling activities, field work, meetings, and
preparation/review/submittal of invoicing. Management of subcontractor (laboratory) activities and
