Re: FY19 -FY21 Scope of Services for Landfill Gas Management Suite™
Four Hills Landfill
Nashua, New Hampshire
Dear Jeff:
Sanborn, Head & Associates, Inc. (Sanborn Head) is pleased to provide this scope of services
to the City of Nashua (City) to assist you with the evaluation and management of landfill gas
(LFG) at the Four Hills Landfill. Specifically, we will continue to provide to you our
interactive, web-based data management and mapping system, Landfill Gas Management
Suite™ (LFGMS) to streamline monitoring, record-keeping, and reporting requirements.
LFGMS’ upload interface accepts data from the GEM-2000, laboratory results, and similar
monitoring data (e.g., slope stability measurements) in electronic format (i.e., .csv format or
similar). LFGMS accepts data through a secure website using a password-protected user
interface. Using LFGMS, the City and designated personnel can view and download tables,
charts, and interactive maps to assess wellfield performance.
OBJECTIVE AND SCOPE OF SERVICES
The objectives of our services are to maintain LFGMS for the Four Hills Landfill and to
provide LFG data management technical assistance to the City. To meet these objectives, we
propose the following scope of services:
Sanborn Head will assist City personnel in implementing LFGMS, and training users on the
system’s functionality, as necessary. If City personnel have questions or require assistance
interpreting the data, we will also be available to provide telephone support services to
review and evaluate system performance on a reasonably frequent, on-going basis, say,
every other week.
We will include costs for data storage on a secure (SSL certificate), password protected,
hosted website (Ifgms.com/) with 500 gigabyte (GB) bandwidth, total storage capacity of up
to 40 GB, firewall protection, and nightly data backup.
We anticipate that you may desire upgrades to the system to incorporate additional features
or modify certain existing features in order to further tailor the system to your needs. We
will perform these activities on an “as-needed” basis upon your request.
