PROJECT: 2009 Central Plume Groundwater Monitoring
Lodi, California
3923.27 — Lodi Task 15
SUBJECT: Scope, Schedule, and Cost Estimate for 2009 Groundwater Monitoring No. of Pages: 2
This memo describes the scope, schedule, and cost estimate for the 2009 groundwater monitoring for the
Central Plume in Lodi, California.
BACKGROUND
The City of Lodi is currently conducting groundwater monitoring for the Central Plume. I n cooperation
with the City over the past 4 years, we have developed a report that emphasizes data -intensive graphics.
This approach provides a focused view of current conditions in the context of historic trends.
The data management and display needed to produce the report is based on several inter -connected
software programs, We use an EQuIS chemical database to receive, check, and store the electronic data
from the laboratory and to prepare the tables. Our maps are prepared using a combination ArcGIS and
Surfer software which is essential to display the time -series graphs and groundwater flow and
contaminant contours.
SCOPE OF WORK
The scope of the work is defined in the new Monitoring and Reporting Program (MRP) Order No. R5-
2008-0813 issued on 16 April 2008 by the California Regional Water Quality Control Board. I n 2008, we
significantly augmented the data and graphics in the reports in accordance with this new MRP. Since the
MRP has been approved and implemented, we do not anticipate significant changes in the reporting
format for 2009.
SCHEDULE
For 2009, the Central Plume groundwater monitoring is required to include sampling in March, June,
September, and December and is required for compliance with the CAO.
