Water Quality Report:
We test water samples weekly. Three of the tests we do weekly indicate
how well our water treatment plant is operating. The treatment system
is designed to reduce iron, manganese, and color. The treatment plant
also reduces arsenic but we do not test for this contaminant in-house.
Testing for arsenic requires sophisticated analytical equipment and
training our staff does not have. The DOH requires we test for arsenic
once every three years (we test more frequently). Test results for
arsenic are consistently below the MCL. Excessive iron, manganese, and
color can lead to low water quality in the distribution system that
will result in increased water quality complaints. Below I have
included charts that will show the average raw water and treated water
for iron, manganese, and color.

Distribution System:
Water Quality:
North Beach Water District collected and submitted five (5)
compliance coliform bacteria water samples in August, 2013.
All water samples tested negative for coliform bacteria
presence.
The District received four (4) water quality calls in August,
2013.
Wiegardt Property Purchase:
I recommend the District waive all contingencies on the
purchase of the Wiegardt Property and arrange closing as soon
as the property subdivision is complete.
DWSRF Projects:
The well drilling is in the final stages. The well drilling is
complete with the installation of the well screen. Well
development and pump testing will be completed in the next two
weeks. The well was drilled to a depth of 174’ deep. Drilling
was stopped at that point because the discovery of a confining
layer (clay). The screen and pack was set from 119’ to 139’.
Preliminary testing indicates the well has a specific capacity
of 10 gpm/ft1. Preliminary iron and manganese test indicate
1 The rate of discharge (gallons per minute) of water form a well per unit
(foot) of drawdown.
Red line is the MCL - .010 mg/L

excellent water quality. (Iron .2 mg/l and manganese .03 mg/l)
The final pump test will be conducted last week of August.
The design work for the Water Main project is complete. The
job will go to bid in October, 2013. The work will be done in
January /February 2014.
227th Lane Customer Generated Infrastructure:
I have received two signed Agreements with down payments. I
have received verbal confirmations from three other property
owners. As soon as I have received four signed agreements and
down payments I will recommend the Board schedule a Public
Hearing for the project.
245th Street Water Main Loop Project:
The design for the project is complete and approved by Pacific
County. I prepared a materials list and sent it to three
suppliers for bids. HD Supply provided the lowest bid at
$20,921.29 plus tax. The order will be delivered the week of
September 16, 2013. Mike Collins and I will schedule the work
as soon as the materials have been delivered.

The color of the raw (well) water is regularly above the EPA SMCL of 15hu
(Hazen Units). The 30hu level is for aesthetic purposes only. Color in water
does not pose a health concern. Washington State has not set an SMCL for
Color.
The red line in the charts represents the Secondary Maximum Contaminant Level
(SMCL), as set by the Environmental Protection Agency (EPA), for iron (Fe)
and manganese (Mn). The filters are removing a large percentage of the iron
in the raw water and lowering the iron levels to well below the SMCL.

We track the water levels in the wells during pumping and when wells are
idle. J-1 Idle tells us what the static water level is at rest. We then
measure the drawdown of all the wells during pumping cycles. We measure from
the top of the casing down to the top of the water on each well. We monitor
the wells closely so that we can address any reduced yield before it becomes
a major problem.
Water Use Efficiency:
The Total Water Produced is the amount of water pumped from the wells each
month. The Authorized Use includes water used to backwash the filters, water
used to flush mains, and other uses for maintaining the water system. The
Total Metered Water Use is the amount of water that is recorded by our new
meters. August’s reading included 699 residential service meters and 6
commercial meters.
Water Quality in Distribution:
The Water Department regularly tests the water in the distribution system for
quality purposes. Chlorine (Cl2) disinfection effectivity is best when the
water is neutral (pH of 7.2). As water becomes more acidic (lower pH) or
alkaline (higher pH) more chlorine will be needed to achieve the same
chlorine disinfection effectivity.
The chlorine (Cl2) residual is being maintained at a low level (±.1 mg/L). We
continue to adjust the Cl2 feed rate to maintain the minimum effective free
chlorine residual in the distribution system.

The color in the distribution system is consistently over the 15hu EPA
established SMCL. People will start to notice a slight yellow tint to the
water when the color is 15 HU. Below 15 it is hard for the eye to see the
color. At thirty and above the water color is very noticeable.
The average distribution water temperature is important to monitor. When the
water is warm disinfection byproducts will be elevated and chlorine will
operate much more efficiently. The average water temperature in August was 60
degrees. The average water temperature in January was 48 degrees.

Requests for Water Main Locates:
The Water Department responded to twelve (12) requests for water main locates
in August.
J-Well Field Improvements –
Work on the J-Well field Kiosks is complete. Tom Kennedy
did an excellent job on the kiosks. The Water Department
would like thank Tom for his selfless efforts in assisting
the Water Department. The J-Well Field Improvements Project
will be complete when the transducers are installed. The
kiosks will be used to mount the electronics for the
transducers and attach antennas to transfer the data to the
computer at the booster building. The transducers will be
installed by the end of the year.
Water Main Replacement (WMR) –
No WMR work was completed in August the WMR project for 2013 will be
completed in the fall.
Meter Installation Project –
98 meters were installed in August. The meters were installed on G Street
from 315th Street south to 295th Street and then 295th Street north on H Street
to about 300th.
Sanitary Survey:
The Department of Health sent the Water System Manager a report on the
Sanitary Survey. The report included three findings that need to be
corrected by December 31, 2013:
1. “Per WAC 246-290-490, a cross connection ordinance is required
for all community systems, which gives the system authority to
enact other requirements of cross connection control (CCC) for
the water system.”
The Board adopted a Cross Connection Control program at the
August Board Meeting (Resolution 2013-08-01). The Board also
authorized a new permanent part-time employee (Cross
Connection Coordinator) to be hired starting January 1, 2013
to implement and maintain the cross connection program.
2. “Please submit a description of the ion exchange treatment cut
sheets for the products and equipment.”
The Water System Manager has provided the requested
information to the DOH.
Page 6 of 7
3. “Please verify that the hatches have adequate seals (gaskets,
ect.) and that the vents have screens.”
The reservoir hatches and screens were inspected and
photographed prior to the Sanitary Survey. We discovered that
the hatches were very rusty and were in need of maintenance.
We have made temporary repairs to two of the hatches. We will
be ordering replacement hatches for all four reservoirs and
replacing them before the end of the year. The vents had
adequate screens.
The Department of Health had three recommendations:
1. “The system should consider flushing multiple times annually
with unidirectional flushing, due to past iron and manganese
issues. This may also help with elevated Disinfection
Byproducts (DBP)”
We currently flush the entire system using unidirectional
flushing once a year in the Spring. The unidirectional flush
requires approximately 160 hours to complete (one employee for
four weeks). We are not experiencing any iron or manganese
complaints (staining). We are experiencing color complaints
but the color is not associated with iron and manganese.
We do targeted unidirectional flushes throughout the year for
DBP control. Due to the high residuals of TTHM the DOH
requires Surfside to test quarterly for TTHM. The DOH looks at
the last four month average of samples. Currently our four
month average is 80 ug/L which is the MCL. The DOH is aware of
our pilot testing to reduce the TTHMs and has agreed to not
issue any enforcement actions during the pilot testing period.
Our pilot test will last from 12 to 24 months starting in
October.
2. “The Water Facilities Inventory (WFI) should be updated as a
non-residential connection appear high, with the new direction
of counting services connections and not the number of units
for non-residential connection. This may reduce the cost of
your operating permit. Please contact Brad Brooks at (360)
236-3049 for assistance with adjusting this number.”
I have contacted Brad Brooks and the WFI should be updated
before the end of the month.
3. “The loading rate for the filters may be oversized at this
point and should be verified in the pilot study. Please verify
the current loading rate of the filters.”
Page 7 of 7
I have asked Russ Porter, Gray and Osborne engineer, to review
the loading rates for the filters and prepare a letter for the
DOH as an addition to his scope of work for the pilot test.
Russ estimated the work would result in a $500.00 addition to
his original estimate. I authorized him to complete the work
and get a letter to DOH by the end of the year.
I have attached a copy of the Sanitary Survey to this report. The
water system received very good marks for management and operations
which is reflected on the top of page 2:
“As a result of recent regulation changes, all community water systems
in Washington have been changed to a three year sanitary survey cycle.
System with no coliform violations, no more than one monitoring
violation and no significant deficiencies from previous survey can
qualify for reduced survey frequency.
Your next survey is in five years.”
