To satisfy the requirements of the Michigan Department of Environmental Quality (MDEQ), the groundwater and air in the vicinity of the Ann Arbor Landfill (AALF) must be sampled and analyzed quarterly. The current contract with Tetra Tech, Inc. for environmental monitoring and maintenance expires on June 30, 2017.
To select the most qualified environmental consulting firm to assist the City with the monitoring and maintenance of the Ann Arbor Landfill, a request for proposals was posted to the Michigan Inter-governmental Trade Network (MITN) BidNet® website. In response to our request, nine environmental consulting firms submitted proposals to perform the work. A selection committee, comprised of City staff reviewed and selected three firms to interview. After Interviews were conducted, Tetra Tech, Inc. was selected as the most qualified consulting firm based on their previous work experience, their proposed work plan, their competitive fee schedule and their interview.
A brief overview of the major tasks to be completed by Tetra Tech, Inc., as part of this contract is summarized below:
Groundwater Monitoring - Groundwater monitoring consists of the collection of static groundwater elevations and groundwater samples from groundwater monitoring wells specific to individual contaminant plumes, i.e., 1,4-dioxane and vinyl chloride at the AALF, in accordance with the MDEQ approved Hydrogeological Monitoring Plan. In addition, the further delineation of 1,4-dioxane will be completed as requested by the MDEQ.
Landfill Gas Monitoring - The current landfill gas monitoring network adequately monitors landfill gasses at the perimeter of the AALF. This network is to be monitored on a quarterly basis.
Wastewater Discharge Monitoring - Monthly discharge readings and quarterly samples will be collected from purge wells and leachate outfall. Quarterly reports will be prepared and submitted to the City of Ann Arbor Wastewater Treatment Plant.
Landfill Systems Maintenance Activities - In addition to the periodic sampling, the purge wells, observation wells, monitoring wells and methane detection system wells associated with the AALF require periodic maintenance. During the course of on-site activities, monitoring system maintenance needs will need to be identified and coordination of their repair will be required.
The agreement includes an option to approve a two-year extension with the same terms and conditions if deemed in the best interest of the City and if funding is available. Tetra Tech, Inc. is in compliance with the requirements of the City’s Non-Discrimination and Living Wage ordinances.
