Dear Mr. Carter:
SUBJECT: Chateau Du Lac Condominium — Lead & Copper Action Level
Exceedance ; . :
This letter will confirm my visit with Mr. Robert Stucker, your operator-in-charge (OIC),
on December 5, 2013, af Chateau Du Lac Condominiums (CDLC). The purpose of the
site visit was to confirm installation of the raw water meter and elimination of the cross -
connection on the pool fill line. ;
Based upon our site inspection and your February 21, 2013, response letter, raw water
metering has been provided and an approved reduced pressure zone backflow
preventer device was installed on the pool fill ine. Since raw water metering has been
provided, water usage will need to be monitored and reported on a yearly basis (annual
pumpage report). Your OIC can assist you in completing the annual pumpage report
each year. : : ,
_Next, the insulation around each hydropneumatic storage tank should be removed in
order to perform a visual inspection of each tank and to complete any necessary
maintenance and/or repairs. We also question the need to insulate the tanks since the
wellhouse room temperature does not fall below freezing. We recommend that the
insulation be permanently removed. ?
Next, the CDLC exceeded the Action Level (AL) for lead in 2011 and has continued to
exceed the lead AL in all subsequent 6-month monitoring periods. Our records show
that the CDLC has failed to meet the lead AL for seven routine monitoring periods since
establishment of the lead and copper monitoring program ini993. ,
Given the number of lead AL-exceedances, the CDLC no longer has the option to
conduct additional rounds of lead and copper monitoring in an attempt to meet future :
ALs. The CDLC must minimize lead and copper in the drinking water by reducing the
corrosion of water pipes and household plumbing that contain lead and copper. The
CDLC must propose a corrosion control treatment plan by January 31, 2014. Potential

Finally, the CDLC must provide customer notice of the most recent lead sample results
and continue to distribute public education materials in accordance to the guidelines

Dear Mr. Carter:
SUBJECT: Water System, Chateau Du Lac Condominium
This letter confirms my visit on October 21, 2011, with Mr. Robert Stucker, your .
operator-in-charge (OIC). The purpose of the visit was to conduct routine water system
surveillance at Chateau Du Lac condominiums. We are somewhat disappointed in the
tack of progress made towards correcting the water related concerns that were noted in
the Chateau Du Lac 2009 Water System Review. These concerns are discussed in -
1.
more detail below.
Chateau Du Lac’s most recent water system general plan is clearly outdated and
the plan has not been updated as we requested. As we discussed, an “as-built”
copy of the general plan needs to be obtained and may be available from the
consuitant who designed the water distribution system. An updated water
system general plan needs to be prepared and a copy sent to us by no later than
January 31, 2012.
A water system Emergency Response Plan (ERP) has not been prepared’ as we
requested. The ERP provides an outline to follow in the event of a water related
emergency (loss of pressure, contamination, etc.). A template that can be used
for preparing the ERP was provided to your OIC. We will review the completed
ERP during our next routine site visit.
Dehumidification has not been provided as a means to control moisture and limit
corrosion within the wellhouse.
The raw water meter inside the wellhouse is not functioning and has not been
replaced as we requested. The raw water meter needs to be repaired or
replaced such that accurate water usage information can be obtained by no Jater
than January 31, 2012.

. Chateau Du Lac’s lead action level was exceeded during routine lead and copper
monitoring in 2011. Two consecutive six-month rounds of lead and copper
monitoring will be required, along with water quality parameter monitoring and
.public education. Specific monitoring & reporting details will be covered j ina
separate letter. Finally, the 2011 exceedance represents the 4" exceedance in
the lead and copper action level since the start of the lead and copper monitoring
program. We will be reviewing the history of Chateau Du Lac’s lead and copper
monitoring program to determine whether a corrosion control study needs to be
conducted and/or treatment needs to be provided.
Finally, according to our records, routine pump and motor maintenance for Well #2 has
not been performed within the last 12 years. As we discussed, Type-| wells (oump &
motor) should be scheduled for routine maintenance once every 5 to 10 years. This
type of preventative maintenance is an accepted standard that is practiced in the
waterworks industry and is essential in minimizing the chance of an unexpected failure
of the well pump/motor and the potential for a loss of water service, Routine pump and
motor atlialiala should be performed for Well #2 during 2012
We look forward to working with you on these and on any other water related matters.

Dear Mr. Carter:
SUBJECT: Water System, Chateau Du Lac Condominium
This letter confirms my visit on November 6, 2008 with your contract operator, Robert Stucker.
The purpose of the visit was to conduct routine water system surveillance. Specific water
system concerns that need attention are discussed below in more detail.
1.
Our most recent copy of Chateau Du Lac’s water system general plan was prepared in
1984, and the plan is clearly outdated. An updated water system general plan was not
available at the time of the site visit. Aiso, it does not appear that an updated plan was
prepared as we requested in our previous visits and correspondence (copy of our January
8, 2007 letter enclosed).
An updated water system general plan needs to be prepared and a copy of the plan sent to
our office by no later that January 31, 2009. As we discussed, the updated general plan
needs to show the location and size of all watermains, hydrants, valves, service lines, etc.
The plan should also show the location of the wells, discharge piping, wellhouse, and
storage facilities.
Chateau Du Lac’s bacteriological sample site plan was updated as we requested. As we
discussed, a third repeat sampling location needs to be added to the plan since one
distribution system sample is collected each month. The updated sample site plan is
approved with the condition that a third repeat sampling tocation is added to the pian.
Our inspection of the wellhouse (west half of the clubhouse basement) revealed that this
area is being used to store much of the swimming poo! equipment. These items make it
cumbersome to perform routine wellhouse activities.
The purpose of a Type-| wellhouse is to allow for flexibility of operation of the water system.
The west half of the basement is dedicated for the wellhouse piping and appurtenances and
is not intended to be used as a storage area for typical outdoor maintenance equipment
including pool supplies and parts. This area must also be accessible only to the water
system operator. These miscellaneous items need to be stored in an area that is separate
