A RESOLUTION OF THE LODI CITY COUNCIL AUTHORIZING
CITY MANAGER TO EXECUTE TASK ORDER NO. 24 WITH
TREADWELL & ROLLO AND PROFESSIONAL SERVICE
AGREEMENT WITH ECOGREEN HYDRO SOLUTIONS FOR
CITYWIDE GROUNDWATER MODELING AND ANALYSIS, AND
FURTHER APPROPRIATING FUNDS
WHEREAS, management of the City's groundwater resources has become increasingly
complex and important, and in September 2012, the City will start up the surface water
treatment plant that will reduce groundwater extraction by 7,000 acre feet per year or more than
40 percent below current levels; and
WHEREAS, in 2008, Treadwell & Rollo prepared a groundwater flow and contaminant
transport model (model) that has been used to predict the movement of volatile organic
compounds (VOC), such as PCE, within the Central Plume Area; and in February 2012, the City
entered into a professional services agreement with Applied Remedial Technologies to include
DBCP water quality data in the model. Results of that work identified three separate DBCP
plumes in the northwest, northeast, and southern areas of the City; and
WHEREAS, as the City brings on line the surface water treatment plant, it is appropriate
to establish a new strategy for operation of the City's well field that is focused upon optimized
coordination with surface water deliveries and the containment and/or treatment of the DBCP
and VOC plumes that are present in the groundwater beneath the City; and
WHEREAS, the services of Treadwell & Rollo and EcoGreen Hydro Solutions (formerly
Applied Remedial Technologies) will expand the model to include the Central, Southern,
Western and Northern VOC plumes and the three DBCP plumes. The model will be used to
simulate the migration of the plumes under various well field pumping scenarios and to optimize
locations for monitoringwells in the Northern, Southern, and Western plume areas.
NOW, THEREFORE, BE IT RESOLVED that the Lodi City Council does hereby
authorize the City Manager to execute Task Order No. 24 in the amount of $37,780 with
Treadwell & Rollo, of Oakland, California, and a Professional Services Agreement in the amount
of $45,340 with EcoGreen Hydro Solutions, of Sunnyvale, California, for citywide groundwater
modeling and analysis; and
BE IT FURTHER RESOLVED that funds in the amount of $100,000 be appropriated
from the PCE/TCE Rates Fund.
