City of Nashua, Public Works Division
Board of Public Works Meeting Date: January 20, 2022
Jeff Lafleur, Superintendent
Solid Waste Department
Approval of Change Order #1 a contract with Chemserve Environmental Analysts
to provide water quality testing services at Nashua landfill sites.
Breakdown of the additional groundwater sampling and analysis costs and
Chemserve’s rates for these services.
To approve Change Order #1 to the contract with Chemserve Environmental
Analysts of Milford, NH for water quality testing services at Nashua landfill sites
for the Solid Waste Department in the amount of $40,795.00. Funding will be
through: Department: 168 Solid Waste; Fund: Solid Waste; Account
Classification: 53 Professional and Technical Services.
The Solid Waste Department entered into a three year contract with Chemserve
starting at the beginning of FY22 to conduct water quality testing services at the
City of Nashua’s landfill sites.
Following the execution of the contract the New Hampshire Department of
Environmental Services (NHDES) requested expanded groundwater sampling and
the initiation of soil and sediment sampling at the Four Hills Landfill in
September of 2021. This has included sampling at 3 additional monitoring wells
and has also included analysis for PFAS. NHDES has also required monthly
testing until further notice.
The additional NHDES requirments sampling and testing has gone well beyond
the original scope of the contract with Chemserve and has cost far more than
originally expected.
The Solid Waste Superintendent and the Environmental Engineer recommend
approving Change Order #1 in the amount of $40,795.00 to the contract for these
additional required water quality testing services.
