Council Member Hansen inquired about the DPE unit. Mr. Prima stated it is provided by
Greg's Drilling.
Council Member Hitchcock asked why the amounts that have been taken out are not equal.
Mr. Prima stated the amounts are not exact and are related to periodically adjusting the
well system.
In response to Council Member Hansen's questions, Mr. Prima stated they will know by
spring if their efforts worked.
In response to Mayor Johnson's question, Mr. Prima stated the abandoned wells cannot be
recaptured because they have been destroyed. Mr. Prima also provided an overview of the
status of the remaining wells in the area.
Council Member Hansen inquired about similar situations in other cities. Mr. Prima stated
every situation in every city is different and the Board's involvement is different. Mr. Prima
shared comparisons with Modesto, Turlock, and Chico. He also stated the experts believe
there are unique conditions in Lodi.
Myrna Wetzel asked if elevation is a factor. Mr. Prima replied no.

City Attorney Schwabauer stated soil types are different in various areas and change
penetration abilities. Mr. Schwabauer stated several states have set up remediation
legislation for dry cleaning businesses as a result. He also compared the Merced situation.
Council Member Hitchcock inquired about the remediation approaches and their affect on
costs. Mr. Prima provided an overview of the various remediation approaches from the pre -
Donovan days to the present, including individual plume assessment and a more unified
approach.
Council Member Hansen suggested presenting the information to the community. City
Manager King stated signage will be placed at the well sites to indicate the work that is
being done.
Mayor Johnson suggested doing two presentations, one more technical in nature and the
other relatively simple.
Council Member Katzakian asked what the typical well depth is. Mr. Prima stated it can be
up to 500 feet.
PUBLIC COMMENTS:
00 In response to Myrna Wetzel's question, Mr. Prima stated a deeper cleaning is more
costly than a shallow one and the human body does not retain and accumulate
PCE/TCE.
00 Pat Patrick inquired about the downtown property that fell out of escrow. City Attorney
Schwabauer stated the Comprehensive Environmental Response, Compensation, and
Liability Act is pretty clear that lenders do not have liability for groundwater. He stated
the City has given out letters regarding liability in connection with property acquisitions,
but it was not approached by this particular business.
In response to Myrna Wetzel's question, Mr. Prima stated PCE/TCE does evaporate
into the air when exposed, but it still needs to be cleaned or destroyed at that time.
