(Sculpture Park), 063000022040 (Sculpture Park), 063000022070 (Sculpture
Park), 063000513235 (Bluff overlooking city park), and 063012340300 (Strip
along Delguzzi Drive) (collectively, "the Property").
4. The Property might be impacted by dioxin and furan contamination from the
former Rayonier Mill Site.
5. By signing this Access Agreement, the City grants to Ecology's sampling
contractor access rights to the parcels identified in paragraph 3 above for the
purpose of taking surface soil samples as described in paragraph 2 above. The
persons taking such samples shall be accompanied by the City's Archaeologist or
the Lower Elwha Kllallam Tribe's Archeolgist, and shall comply with all
applicable City policies. The City shall be responsible for notifying Ecology or
Ecology's contractor in advance of any applicable City policies.
6. The term of this Access Agreement shall be for the time period from November
10,2008 through November 12,2008.
7. Each Party shall defend, protect, and hold harmless the other Party from and
against all claims, suits or actions arising from the negligent acts or omissions of
its employees and/or authorized representatives while performing under the
terms of this Access Agreement.
8. The Parties may mutually amend this Access Agreement. Any amendments
shall not be binding on any Party unless such amendments are in writing and
signed by an authorized representative of each Party.
9. The Access Agreement between the Parties contains all terms and conditions
agreed upon by and between the parties. No other understandings, verbal or
otherwise, regarding the subject matter of this Agreement shall be enforceable
on any of the Parties.

RE: Results of soil sampling from your propeli)' at End of Caroline Street, Parcel 0630005 I 3235
Dear Nathan West, City ofPOIi Angeles:
Thank you for allowing soil sampling to be conducted on your propeli)' as part of the Washington State
Department of Ecology's Rayonier Mill Off-Propeli)' Soil Dioxin Study. This study was designed to
determine the amount of dioxins and dioxin-like compounds in soils near the former Rayonier Mill. The
study will also look at the former Rayonier Mill's contributions, if any, to those amounts of dioxins. You
requested that the results of chemical analysis of the soil sample from your property be sent to you. This
letter summarizes those results.
State Standard
There are hundreds of different dioxin-like chemicals, called congeners. The analysis of your soil sample
focused on 17 of these chemicals; believed to pose the greatest risk to human health. The total toxic
equivalent concentration represents the combined effect of these 17 congeners. It is given in pmis per
trillion Cppt) and the calculation is eXplained in the attached Technical Details.
The state soil cleanup level for dioxins, under the Model Toxics Control Act, is I 1.1 ppt. This is the
concentratiOll of dioxin in soil that is considered protective of human health and the environment.
However, your single sample result is not enough to determine health risk, or whether your property is
contaminated. Almost all soil in Washington is believed to have some level of dioxins, even in areas that
are not known to have industrial contamination.
Your Soil Sampling Result
One sample from your propeli)' was chemically analyz~d. We found I. I ppt total dioxin. Details of the
sample collection and analysis are included in the attached Technical Details.
What Do the Results Show?
Eighty-five total samples were analyzed in this study, one from each property sampled. Dioxin
concentrations ranged from 0.8 to 76.3 ppt. Forty-five of the samples were below the state cleanup level
of 11.1 ppt Ecology is doing further analysis of the reSli Its, with the goal of identiJying sources of the
dioxin and any contribution by Rayonicr. Ecology will wait until the 11nal repOlt is completed in the
spring of2009 before taking any further steps.
,,<.:r~[tt~lB
Q'I:y
~~
'~ . ,,\, j:
. ., o. ,).',
From your results, the following conclusioSls can be made:
. The sample taken from your property was below the state cleanup level of 11.1 ppt.
. A single sample cannot predict if there is a health risk on your property. The sample was taken
from the most undisturbed part of your property. It may not be from an area where humans are
exposed.
. This single sample cannot be used to say whether an entire property is contaminated or not.
Dioxin levels can vary widely, even within a single propeliy. Other palis of your property may
not have the same results.
. Every property has a different history. The map of study results cannot help predict dioxin levels'
on different parts of your property or on other properties.
Healthy Actions
Most people are exposed to very small levels of dioxins when they consume food or milk, breathe air, or
have skin contact with dioxin contaminated soils or other materials. You can limit your family's
exposure to different types of possible soil contamination by:
. Washing your hands with soap and water.
. Removing shoes before entering your home.
. Scrubbing fruits and vegetables frc)fn the garden.
. Dusting with a damp cloth and vacuuming regularly.
. Keeping toys and pacifiers clean. .

Rayonier Mill Off-Property 50;1
Dioxin Study
'Toxies rCleanu,p lProgram ,Fe'brua~y 2009 ,
Preliminary Results
In the fall of 2008, the Washington State Department of Ecology
(Ecology) took one soil sample from 85 different locations near
and downwmd of the Rayonier Mill property. The purpose of
this sampling is to help determine:
· The magnitude of dioxin soil contamination.
· The former Rayonier Mill's contribution to measured dioxin
contamination,. compared to other possible sources.
Ecology has preliminary results showing the magnitude of soil
dioxin contamination. The results provide valuable information
about the presence and characteristics of dioxins in the area.
A consultant is now analyzing the data to see if specific dioxin
sources can be identified. The analysis and final report will be
ready in late spring of 2009. This fact sheet provides the range of
dioxin concentrations found during sampling, and a map of
sample results. .
When looking at the results, keep in mind that:
· Dioxins a!eUnintentional byproducts of human activities and'
natural processes. They do not break down easily in the en-
. vironment and, as a result, are found everywhere.
· In this fact sheet, Ecology uses the state cleanup level of 11.1
parts per trillion (ppt) only for comparison. It is based on an
additional cancer risk of one in a million.
· A single sample cannot be used to say whether a property is
contaminated or not. Dioxin levels can vary widely, even
within a single property. Other parts of a property may not
have the same results.
· Every property has a different history. The map of study re-
sults cannot help predict dioxin levels on different parts of
your property or on other properties.
· A single sample cannot predict if there is a health risk on a
property. Samples were taken from the most undisturbed
part of each property in the study, which may not be an area
where humans are exposed.
What Do the Results Show?
Eighty-five samples were analyzed. Dioxin concentrations range.
from 0.8 parts per trillion (ppt) to 76.3 ppt.

Note: Dioxin levels are shown in 10 ppt intervals to make
data easier to view.
. Forty-five samples were below the MTCA
cleanup level of 11.1 ppt (see Figure 1).
. Twenty-five samples were between 11.1 ppt
and 20 ppt.
.. Twelve samples were between 20 and 30
ppt, and three were over 30 ppt.
Ecology will now look at the overall pattern of
dioxin levels and try to determine the source or
sources. The agency must wait until the final
report is complete before taking any further
steps.
If you or members of your household are con-
cerned, you can reduce exposure to potentially
contaminated soil by following the Healthy Ac-
tions shown in the box to the right.
Why Release Early Results Now?
Ecology committed to providing the study re-
sults to property owners as soon as they were
available.
What Happens Next?
The final soil dioxin report will include all the
dioxin test results and findings about the rela-
tive contribution of the former Rayonier Mill
and other possible sources. This information
will help Ecology decide how to address soil
dioxin contamination. The report will be ,avail-
able for public review during late spring of
2009. Please check the Ecology Web site (page
1) for updates.
Healthy Actions
You can limit your family's exposure to diox-
ins and any other type of possible soil con-
tamination by:
. Washing your hands after working or
playing outside, and before eating.
. Scrubbing fruits and vegetables from the
garden.
. Vacuuming regularly and dusting with a
damp cloth.
. Keeping children's toys clean.
Also: Dioxins from air emissions tend to stay
in the upper layer of soil until they are dis-
turbed. Landscaping and development can
dilute these dioxins, while grass and other
ground cover can help prevent exposure.

Figure 2. Map showing sample results from the Rayonier Mill Off-Property Soil Dioxin Study.
This map is not "evidence" of a specific source or sources of dioxins. Although you may see "patterns" on the map, these data cannot
be used to predict dioxin levels on your property. Each property is different-places with disturbed soils (recently built on or land-
scaped) may have lower levels of dioxins. Fires or herbicide use can increase dioxin levels on a property.

What are dioxins?
Dioxins are a family of chemicals with
similar chemical structures and biological
effects. They are unintentional by-
products of both human activities and natural processes.
They do not break down easily in the environment, and as
a result, are found everywhere. Most people are exposed
to very small levels of dioxins when they consume food or
milk, breathe air, or have skin contact with dioxin con-
taminated soils or other materials.
Sources: Dioxins can be formed during industrial proc-
esses, such as chlorine bleaching of pulp (done at the
Rayonier Mill in the past) and certain types of chemical
manufacturing. Dioxins can also form during combustion
(burning) and waste incineration. This includes burn bar-
~IS' fireplaces, and wood stoves. ~

Technical Details
How was the samplefrom my property collected?
Sample Point Selection
Soil sampling points were chosen from the least disturbed parts of the each propf?rtyin the study. The
following areas were excluded or avoided:
· Disturbed areas, including:
o Construction sites
o Areas around concrete pads or foundations
o Telephone and electric poles
o Landscaping and ornamental planters
o Building drip lines and down spouts
o Gardens, dog runs, and areas where animals burrow
· Soils within a 20-foot radius of creosote-treatep wood. Areas within a six-foot radius from other
forms of treated wood were excluded from sampling.
· Soils within six feet of high-traffic areas (parking lots, roadways, or sidewalks).
· Soils within 20 feet of bum pits, fire pits, or other burning; areas near wood-burning fireplace
chimneys.
· Steeply sloped areas or areas potentially shielded from deposition of Rayonier Mill emissions.
· Hummocks, paths used by animals or humans, areas lacking ground cover, and other areas
disturbed by treefall or animal digging within forested areas.
· Forested areas dominated by immature trees (less than 30 years old), areas that were recently
reforested, and areas with evidence of recent fires. .
· Areas between forested and undeveloped prop~rties where dumping is more common.
If samples were collected around these exclusion areas, the presence of, type, and distance from the
exclusion area were noted in the field log book, field sampling forms, or with photographs.
Subsample Locations at Sampling Points
After choosing a sampling point at a property, five subsample locations were marked on the ground using
pin flags. The default design was to collect subsamples from the four comets and the center of 1 a-foot by
10-foot template (see example below). Most residential yards fit this template size. At some properties,
this layout may have been modified as long as subsamples were separated by at least 5 feet. For sampling
at forested locations, the size ofthe sampling template was at least 10-foot by 10-foot square or larger, if
needed. Samples may have been collected up to 50 feet apart, and slightly off of the comers of a square
template to get around obstacles or excluded areas.

@ Subsample location
After markingsubsample locations with flags, a photograph of the sampling point was taken and recorded
in the field logbook. A sketch oflandmarks on the property, the sample location point, and other site
information was recorded on the field sampling form Field staff also recorded the latitude and longitude
at the center of the sampling point using a global positioning system device.
The foHowing procedures were used to collect surface soil samples for dioxin. Cigarette smoke is a
potential source of dioxins andfurans, so there was absolutely no smoking during sample collection.
. .
Exhaust from vehicles and generators can also be a source of dioxins and furans, so samples were
collected away from running vehicles or generators, and all combustion engines, to the extent possible.
Groundcover Removal
Groundcover such as grass, other vegetation, rocks, or pebbles, was removed from an area of about 8
inches by 8 inches. The surface layer of grass, leaves, or twigs at each subsample point was removed
using a spade. The groundcover was only removed to the point where soil was exposed, being careful not
to disturb the soil below.
Subsample Collection
The samples were collected as follows:
. A clean, stainless steel sampling bowl, 8-ozjar, spoon and nitrile gloves were used at each
sample location.
. The hole was excavated to a depth of 3 inches with a Clean spoon. Roots and large rocks or other
objects that would keep the spoon from moving continuously along the sidewall were removed.
. The side of the hole was scraped with the spoon, beginning at the bottom. The sidewall was
scraped slowly, adjusting pressure against the sidewall to collect an equal amount of soil along
the entire 3-inch sidewall length. More pressure was required to scrape hardpan material and less
for looser, sandy material.
.. The sidewall was then scraped as many times as needed to fill the jar. This process was repeated
at the four other subsample locations. All five subsamples were emptied into a stainless steel
bowl.
. Large rocks or large pieces of organic matter, such as sticks or reots, were removed from [he
bowl, taking care to keep soil particles that stuck to debris.
.
. .
. The soil in the bowl was mixed with the collection spoon and then the soil was separated into four
equal parts by drawing an "X" in the soil with the spoon. One spoonful of soil from each quarter
was placed into clean sample containers from the laboratory. This process was repeated,
alternating containers until they were all full.
· The labeled sample containers were then placed into an iced cooler.
· Replicate samples collected along with investigative samples are intended to be identical samples
collected and sent to the same or a different lab for comparison of results. Any leftover soil was
returned to the hole.
· The pin flags were removed and the site was returned to its original state as best as possible.
Potting soil was used to fill any holes created by sample removal. .
How is the total toxic equivalent concentration (TEQ) calculated?
TEQs are calculated values that allow us to compare the toxicity of different combinations of dioxins.
This study looks at 17 different types or congeners of dioxin. Each of these congeners has its own level
oftoxicity. A toxicity equivalency factor (TEF) has been given to each congener. The TEFs compan: the
toxicity of each congener to the toxicity of 2,3,7,8 - tetrachlorodibenzo-p-dioxin (2,3,7,8 - TCDD).
This congener is considered the most toxic and best-studied of the dioxins and furans. To use the TEF
method, each of the compounds in the following table must be analyzed and included in the calculations.

Example
Consider a site where the soil is contaminated with a mixture of dioxins and dioxin-like compounds.
Measured soil concentrations and calculations are shown in the table below. The following steps should
be used to determine the TEQ for the sample.
1. Analyze the soil sample to fmd the concentration of each congener (Shown in column 1).
2. Multiply each congener by the TEF (Shown in column 2).
3. Add the answers in Step 2 to get the total TEQ. This value is sometimes called the total toxicity
equivalent concentration (TTEC) by Ecology.

RE: Results of soil sampling from your property at Sculpture Park, Parcels 63000022040/6300002207
Dear Nathan West, City of Port Angeles:
Thank you for allowing soil sampling to be conducted on your property as part of the Washington State
Department of Ecology's Rayonier Mill Off-Propelty Soil Dioxin Study. This study was designed to
determine the amount of dioxins and dioxin-like compounds in soils near the former Rayonier Mill. The
study will also look at the former Rayonier Mill's contributions, if any, to those amounts of dioxins. You
requested that the results of chemical analysis of the soil sample from your propelty be sent to you. This
letter summarizes those results.
State Standard
There are hundreds of different dioxin-like chemicals, called congeners. The analysis of yours oil sample
focused on l7 ofthese chemicals, believed to pose the greatest risk to human health. The total toxic
equivalent concentration represents the combined effect of these 17 congeners. It is given in parts per
trillion (ppt) and the calculation is explained in the attached Technical Details.
The state soil cleanup level for dioxins, under the Model Toxics Control Act, is n.1 ppt. This is the
concentration of dioxin in soil that is considered protective of human health and the environment.
However, your single sample result is not enough to determine health risk, or whether your property is
contaminated. Almost all soil in Washington is believed to have some level of dioxins, even in areas that
are not known to have industrial contamination.
Your Soil Sampling Result
One sample from your property was chemically analyzed. We found 12.0 ppt total dioxin. Details ofthe
sample collection and analysis are included in the attached Technical Details.
What Do the Results Show?
Eighty-five lotal samples were analyzed in this study, one from each propclty sampled. Dioxin
concentrations ranged from 0.8 to 76.3 ppt. FOlty-five of the samples were below the state cleanup level
of 11.1 ppt. Ecology is doing further analysis of the results, with the goal ofidentif}dng sources of the
dioxin and any contribution by Rayonicr. Ecology will wait until the final repOlt is completed in the
spring of 2009 before taking any further steps.'
if'~'
~i~'
From your results, the following conclusions can be made:
. The sample taken from your property was above the state cleanup level of 11.1 ppt.
. A single sample cannot predict ifthere is a health risk on your property. The sample was taken
from the most undisturbed part of your property. It may not be from an area where humans are
exposed.
. This single sample cannot be used to say whether an entire property is contaminated or not.
Dioxin levels can vary widely, even within a single property. Other parts of your property may
not have the same results.
. Every property has a different history. The map of study results cannot help predict dioxin levels
on different parts of your property or on other properties.
Healthy Actions
Most people are exposed to very small levels of dioxins when they consume food or milk, breathe air, or
have skin contact with dioxin contaminated soils or other materials. You can limit your family's
exposure to different types of possible soil contamination by:
. Washing your hands with soap and water.
. Removing shoes before entering your home.
. Scrubbing fruits and vegetables from the garden.
. Dusting with a damp cloth and vacuuming regularly.
. Keeping toys and pacifiers clean.

Rayonier Mill Off-Property Soil
Dioxin Study
"f!
Toxies Cleanup Program Februa~y ,2009
Preliminary Results
In the fall of 2008, the Washington State Department of Ecology
(Ecology) took one soil sample from 85 different locations near
and downwind of the Rayonier Mill property. The purpose of
this sampling is to help determine:
· The magnitude of dioxin soil contamination.
· The former Rayonier Mill's contri15ution to measured dioxin
contamination" compared to other possible sources.
Ecology has preliminary results showing the magnitude of soil
dioxin contamination. The results provide valuable information
about the presence and characteristics of dioxins in the area.
A consultant is now analyzing the data to see if specific dioxin
sources can be identified. The analysis and final report will be
ready in late spring of 2009. This fact sheet provides the range of
dioxin concentrations found during sampling, and a map of
sample results.
When looking at the results, keep in mind that:
· Dioxins a!eunintentional byproducts of human activities and'
natural processes. They do not break down easily in the en-
,vironmentand, as a result~ are found everywhere.
· In this fact sheet, Ecology uses the state cleanup level of 11.1
parts per trillion (ppt) only for comparison. It is based on an
additional cancer risk of one in a million.
· A single sample cannot be used to say whether a property is
contaminated or not. Dioxin levels can vary widely, even
within a single property. Other parts of a property may not
have the same results.
· Every property has a different history. The map of study re-
sults cannot help predict dioxin levels on different parts of
your property or on other properties.
· A single sample cannot predict if there is a health risk on a
property. Samples were taken from the most undisturbed
part of each property in the study, which may not be an area
where humans are exposed.
What Do the Results Show? "
Eighty-five samples were analyzed: Dioxin concentrations range "
from 0.8 parts per trillion (ppt) to 76.3 ppt. ' ,

. Forty-five samples were below the MTCA
cleanup level of 11.1 ppt (see Figure 1).
. Twenty-five samples were between 11.1 ppt
and 20 ppt.
. Twelve samples were between 20 and 30
ppt, and three were over 30 ppt.
Ecology will now look atthe overall pattern of
dioxin levels and try to determine the source or
sources. The agency must wait until the final
report is complete before taking any further
steps.
If you or members of your household are con-
cerned, you can reduce exposure to potentially
contaminated soil by following the Healthy Ac-
tions shown in the box to the right.
Why Release Early Results Now?
Ecology committed to providing the study re-
sults to property owners as soon as they were
available.
What Happens Next?
The final soil dioxin report will include all the
dioxin testresults and filldingsabouttherela-
tive contribution of the former Rayonier Mill
and other possible sources. This information
will help Ecology decide how to address soil
dioxin contamination. The report will..be .avail-
able for public review during late spring of
2009. Please check the Ecology Web site (page
1) for updates.
Healthy Actions
You can limit your family's exposure to diox-
ins and any other type of possible soil con-
tamination by:
. Washing your hands after working or
playing outside, and before eating.
. Scrubbing fruits and vegetables from the
garden.
. Vacuuming regularly and dusting with a
damp cloth.
. Keeping children's toys clean.
Also: Dioxins from air emissions tend to stay
in the upper layer of soil until they are dis-
turbed. Landscaping and development can
dilute these dioxins, while grass and other
ground cover can help prevent exposure.

This map is not "evidence" of a specific source or sources of dioxins. Although you may see "patterns" on the map, these data cannot
be used to predict dioxin levels on your property. Each property is different-places with disturbed soils (recently built on or land-
scaped) may have lower levels of dioxins. Fires or herbicide use can increase dioxin levels on a property.

What are dioxins?
Dioxins are a family of chemicals with
similar chemical structures and biological
effects. They are unintentional by-
products of both human activities and natural processes.
They do not break down easily in the environment, and as
a result, are found everywhere. Most people are exposed
to very small levels of dioxins when they consUme food or
milk, breathe air, or have skin contact with dioxin con-
taminated solis or other materials.
SOIo/rces: Dioxins can be formed during industrial proc-
esses, such as chlorine bleaching of pulp (done at the
Rayonier Mill in the past) ano certain types of chemical
manufacturing. Dioxins can also form during combustion
(burning) and waste incineration. This includes burn bar-

Technical Details
How was the sample from my property collected?
Sample Point Selection.
Soil sampling points were chosen from the least disturbed parts of the each prop~rtyin the study. The
following areas were ex-c1uded or avoided:
. Disturbed areas, including:
o Construction sites
o Areas around concrete pads or foundations
o Telephone and electric poles
o Landscaping and ornamental planters
o Building drip lines and dowp. spouts
. 0 Gardens, dog runs, and areas where animals burrow
. Soils within a 20-foot radius of creosote-treated wood. Areas within a six-foot radIUS from other
forms of treated wood were excluded from sampling.
· Soils within six. feet of high-traffic areas (parking lots, roadways, or sidewalks).
· Soils within 20 feet of bum pits, fire pits, or other burning; areas near wood-burning fireplace
chimneys.
· Steeply sloped areas or areas potentially shielded from deposition of Rayonier Mill emissions.
· Hummocks, paths used by animals or humans, areas lacking ground cover, and other areas
disturbed by treefall or animal digging within forested areas.
· Forested areas dominated by immature trees (less than 30 years old), areas that were recently
reforested, and areas with evidence of recent fires. .
· Areas between forested and undeveloped prop~rties where dumping is more common.
If samples were collected around these exclusion areas, the presence of, type, and distance from the
exclusion' area were noted in the field log book, field sampling forms, or with photographs.
Subsample Locations at Sampling Points
After choosing a sampling point at a property, fivesubsample locations were marked on the ground using
pin flags. The default design was to collect subsamples from the four corners and the center of 10-foot by
J O-foot template (see example below). Most residential yards fit this template size. At some properties,
this layout may have been modified as long as suhsamples were separated by at least 5 feet. For sampling
at forested locations, the size of the sampling template was at least 10-foot by 10-foot square or larger, if
needed. Samples may have been collected up to 50 feet apart, and slightly off of the corners of a square
template to get around obstacles or excluded areas.

C) Subsample location
After marking subsample locations with flags, a photograph of the sampling point was taken and recorded
in the field log book. A sketch of landmarks on the property, the sample location point, and other site
information was recorded on the field sampling form Field staff also recorded the latitude and longitude
at the cerlter of the sampling point using a global positioning system device.
The following procedures were used to collect surface soil samples for dioxin. Cigarette smoke is a
potential source of dioxins and furans, so there was absolutely no smoking during sample collection.
Exhaust from vehicles and generators can also be a source of dioxins and furans, so samples were
collected away from running vehicles or generators, and all combustion engines, to the extent possible.
Groundcover Removal
Groundcover such as grass, other vegetation, rocks, or pebbles, was removed from an area of about 8
inches by 8 inches. The surface layer of grass, leaves, or twigs at each subsample point was removed
using a spade. The groundcover was only removed to the point where soil was exposed, being careful not
to disturb the soil below.
Subsample Collection
The samples were collected as follows:
. A clean, stainless steel sampling bowl, 8-ozjar, spoon and nitrile gloves were used at each
sample location.
. The hole was excavated to a depth on inches with a Clean spoon. Roots and large rocks or other
objects that would keep the spoon from moving continuously along the sidewall were removed.
. The side of the hole was scraped with the spoon, beginning at the bottom. The sidewall was
scraped slowly, adjusting pressure against the sidewall to collect an equal amount of soil along
the entire 3-inch sidewall length. More pressure was required to scrape hardpan material and less
for looser, sandy material.
.G The sidewall was then scraped as many times as needed to fill the jar. This process was repeated
at the four other subs:1mple locations. All five subsampks were emptied into a stainless steel
bowl.
" Large rocks or large pieces of organic matter, sllch as stick:~ or roots, were removed from the
bowl, taking care to keep soil p:lrtic1cs that stuck to debri::;.
. The soil in the bowl was mixed with the collection spoon and then the soil was separated into four
equal parts by drawing an "X" in the soil with the spoon. One spoonful of soil from each quarter
was placed into clean sample containers from the laboratory. This process was repeated,
alternating containers until they were all full.
. The labeled sample containers were then placed into an iced cooler.
. Replicate samples collected along with investigative samples are intended to be identical samples
collected and sent to the same or a different lab for comparison of results. Any leftover soil was
returned to the hole.
. The pin flags were removed and the site was returned to its original state as best as possible.
Potting soil was used to fill any holes created by sample removal. .
How is the total toxic equivalent concentration (TEQ) calculated?
TEQs are calculated values that allow us to compare the toxicity of different combinations of dioxins.
This study looks at 17 different types or congeners of dioxin. Each of these congeners has its own level
of toxicity. A toxicity equivalency factor (TEF) has been given to each congener. The TEFs compar€ the
toxicity of each congener to the toxicity of 2,3,7,8 - tetrachlorodibenzo-p-dioxin (2,3,7,8 - TCDD).
This congener is considered the most toxic and best-studied of the dioxins and furans. To use the TEF
method, each of the compounds in the following table must be analyzed and included in the calculations.

Example
Consider a site where the soil is contaminated with a mixture of dioxins and dioxin-like compounds.
Measured soil concentrations and calculations are shown in the table below. The following steps should
be used to determine the TEQ for the sample.
1. Analyze the soil sample to fmd the concentration of each congener (Shown in column 1).
2. Multiply each congener by the TEF (Shown in column 2).
3. Add the answers in Step 2 to get the total TEQ. This value is sometimes called the total toxicity
equivalent concentration (TIEe) by Ecology.
