or disruption if the Vendor is asserting a schedule change or disruption.
3.The Vendor shall keep complete records of extra costs and time incurred as
a result of the protested work. The City shall have access to any of the Vendor's records needed
for evaluating the protest.
The City will evaluate all protests, provided the procedures in this section
are followed. If the City determines that a protest is valid, the City will adjust payment for work
or time by an equitable adjustment. No adjustment will be made for an invalid protest.
B.Vendor's Duty to Complete Protested Work. In spite of any protest, the Vendor
shall proceed promptly to provide the goods, materials and services required by the City under this
Agreement.
C.Vendor's Acceptance of Changes. The Vendor accepts all requirements of a change
order by: (1) endorsing it, (2) writing a separate acceptance, or (3) not protesting in the way this
section provides. A change order that is accepted by Vendor as provided in this section shall
constitute full payment and final settlement of all claims for contract time and for direct, indirect
and consequential costs, including costs of delays related to any work, either covered or affected
by the change.
D.Failure to Protest Constitutes Waiver. By not protesting as this section provides,
the Vendor also waives any additional entitlement and accepts from the City any written or oral
order (including directions, instructions, interpretations, and determination).
E.Failure to Follow Procedures Constitutes Waiver. By failing to follow the
procedures of this section, the Vendor completely waives any claims for protested work and
accepts from the City any written or oral order (including directions, instructions, interpretations,
and determination).
VII.CLAIMS. The Vendor shall give written notice to the City of all claims other than change
orders within fourteen (14) calendar days of the occurrence of the events giving rise to the claims.
Any claim for damages, additional payment for any reason, or extension of time, whether under
this Agreement or otherwise, shall be conclusively deemed to have been waived by the Vendor
unless a timely written claim is made in strict accordance with the applicable provisions of this
Agreement; or, if (and only if) no such provision is applicable, unless that claim is set forth in
detail in writing and received by the City within seven (7) calendar days from the date Vendor
knew, or should have known, of the facts giving rise to the claim. At a minimum, a Vendor's
written claim must include the information set forth regarding protests in Section VI(A)(2)(a)-(e).
FAILURE TO PROVIDE A COMPLETE, WRITTEN NOTIFICATION OF CLAIM
WITHIN THE TIME ALLOWED SHALL BE AN ABSOLUTE WAIVER OF ANY CLAIMS
ARISING IN ANY WAY FROM THE FACTS OR EVENTS SURROUNDING THAT CLAIM
OR CAUSED BY THAT DELAY.

Technical Memorandum
Date: Tuesday, February 11, 2020
Project: City of Bremerton Wastewater Salinity Impact Study
To: William Davis and Ned Lever, City of Bremerton
From: Michael Murray and Eric Bergstrom, HDR
Subject: Land Application Site - Recommendations and Instructions for Sampling
HDR visited the City of Bremerton biosolids land application site on December 20, 2019. In
attendance for the site visit were Mike Murray and Bryce Figdore for HDR, accompanied by the
City of Bremerton’s Dave Denis and Ned Lever. This technical memorandum presents HDR’s
recommendations and instructions for soil sampling and biosolids sampling for salts that was
discussed during the site visit.
Background
The City of Bremerton operates a Class B biosolids forest land application site comprised of two
areas with total of approximately 520 acres. The City land applies its biosolids using a sludge
slinger that distributes the solids up to a distance of 170 feet. Beginning in 2014, the City
became concerned of potential salt damage to trees and canopy understory from the application
of biosolids. The City’s concern is related to a measurable increase in influent wastewater
electrical conductivity (a measure of inorganic salt concentrations in water) that was observed in
wastewater sampling and the potential carryover of this salt into the biosolids.
Sampling
After reviewing the forested land application area and discussing potential salinity concerns with
staff, HDR provides the following recommendations:
Soil Sampling:
•Soil samples should be collected during the summer months and preferably during a
hot dry weather trend. The goal is collect samples after biosolids application
(preferably 2 to 3 days after application) and during a time where rainfall is minimal.
Soil samples may be collected during wet weather, though it is not preferred. If soil
sampling during wet weather is required, then sampling should be completed within
48 hours following biosolids application.
•Collect a composite soil sample for each of the designated sites in Areas 1 and 2.
For each area, collect 8 subsamples at 0- to 1-foot depth using a shovel, trowel, or
soil auger or probe, place samples into a clean bucket or stainless steel bowl, lightly
mix (blend) the subsample soils by hand, and then place the sample (or portion of it)

into a 1-gallon zip-lock baggie. Sample locations should be representative of the
designated area, but within the 170 foot biosolids sling area.
• Based on the Biosolids Program Site Map there are 14 application areas within Site
1 and 7 areas within Site 2, resulting in the collection of 21 soil samples. A map is
attached illustrating Site 1 and Site 2, with a recommended sampling approach
provided. As described in the map, actual sampling locations are determined in the
field (general approach and sampling areas are provided in the maps). For each
field, it is recommended that the sampler start at the road access (where the truck
applied biosolids), and select 8 locations within 170 feet from the road (representing
areas where biosolids are applied). Locations should be based on best judgement
but ideally sample locations are spatially representative of the field within 170 feet of
the road. The goal is to understand typical salt levels in a field that received direct
biosolids application.
• Place soil samples into a cooler, add chilled ice packs, and ship to an agricultural soil
testing laboratory. If the City does not have a preferred laboratory, HDR
recommends Kuo Testing Labs of Othello, WA. HDR recommends that the
laboratory perform the following test on the samples: Test W2, along with soluble
salts (note W2 is a test for west of the Cascades and includes nutrients, and may
provide information on any nutrient imbalances).
Biosolids Sampling:
HDR recommends that the City measure soluble salts in the biosolids by executing the
following:
• Collect three separate biosolids samples that are representative of biosolids going to
the land application site. It is recommended that samples be collected from the
storage bunker at the site, one sample per week for one year. For each biosolids
sample, collect 8 subsamples from within the stockpile (randomly select 8 locations
and sample within the pile avoiding the outer 6 inches), placing the subsamples into
a bucket, lightly mix, and then transfer a portion of the mixed sample to a 500-mL
glass sample jar. Measure soluble salts following the attached method (see last page
of this technical memorandum). Results are expressed in mmhos/cm.
Interpretation
Once sampling results are available from the soil and biosolids testing, HDR will review the data
and provide interpretation.

Soluble Salts in Biosolids
Place 200 grams of biosolids (wet weight) into a 500 mL glass or plastic beaker. Slowly add
deionized water and stir by hand using spoon or spatula. Continue to add water until a paste is
created.
At saturation, the biosolids paste:
• Does not have free standing water on the surface of the paste.
• Paste slides freely and cleanly off a spatula
• Paste will flow slightly when the container is tipped to a 45 degree angle from horizontal.
Allow the paste to sit for 1 hour. Add water if necessary to get paste characteristics described
above.
Next, filter the extract to obtain the filtrate (liquid). One approach to filtering is to transfer
saturation paste to buchner funnel filter paper (or equivalent) and spread evenly over surface.
Apply vacuum and collect filtrate in test tube. Discontinue vacuum when cracks appear in the
paste.
Measure the electrical conductivity of the filtrate following SM2510 for conductivity
measurement procedures (most labs routinely run electrical conductivity). This is the same as
measuring water samples for conductivity.

Sampling Approach for each Field
•Access each field from road that is used for biosolids application (slinger truck).
•Divide the road along the field into 4 equal segments (approximate, this does not need to be exact).
•Within each segment, collect 2 subsamples:
•The 1st sample approximately 50 feet from the road (sample is 0 to 1 foot depth). Place sample in bucket (or bowl).
•The 2nd sample approximately 100 feet from the road (sample is 0 to 1 foot depth). Place sample in bucket.
•Samples can be in approximate straight line at 50 and 100 feet from the road. Use you best judgement on locations
we are looking for representative soil locations that have high chance of receiving biosolids from the slinger.
•Repeat this in the remaining 3 segments (place samples in same bucket as other segments). Thus, bucket has 8 subsamples.
•Mix soils in the bucket, and then take enough sample from bucket to fill about ¾ of 1-gallon zip-lock baggie.
•Repeat for other fields.
