Aleknagik Traditional
Council Indoor Air Quality
Program
National Tribal Forum on Air Quality
At
Tulsa, Oklahoma
May 22-24, 2012
How we got started
• Submitted the grant on February 18, 2011
• Tribal Air Quality Cooperative Agreement under a subawards covered by Code of Federal Domestic
Assistance (CFDA) # 66.038
• Which was funded thru the U. S Environmental
Protection Agency Region 10
• Administered by Alaska Native Tribal Health
Consortium; Division of Environmental Health and
Engineering (
DEHE)
• We were awarded the Cooperative Agreement on
March 21, 2011
What the Project Consist of
• To increase awareness of community residents
and leaders of sources of air pollution and health
impacts.
• Do quarterly newsletters to educate tribal
members
• Do an air assessment of source pollution
• Partner with ANTCH and BBAHC
• Assess individuals homes of source pollution
Trainings Attended.
• I attended a Building Ventilation
and Energy Course thru the
University of Alaska-Fairbanks,
Bristol Bay Campus.
• This course helped me to better
understand how a house works.
• I also attended a webinar which
was: Using Instruments to Measure
Indoor Air Quality: How and
When they can be useful in your
Tribal IAQ Investigation.
Community Meeting
• Held a community meeting
on May 28, 2011
• I showed video’s on road
dust, wood smoke, and Solid
Waste. (AK tribal air toolkit)
• I also did the fish tank
experiment for air conversion
and used bar straws to show
how an asthmatic felt like
when having an asthma
attack.
• We had 19 participates at the
meeting.
Instruments
• Q-Trak is an instrument
that measures:
• CO-Carbon Monoxide
• CO² -Carbon Dioxide
• Rh- Relative Humidity
• Temp- Temperature
• Dust Trak is an
instrument which
measures particulate
matter 2.5
Quality Assurance Project Plan
• Alaska Native Tribal Health Consortium-Chris
Fish worked on the Quality Assurance Project
Plan (QAPP)
• Most EPA projects do need them such as:
• Water Quality Work
• Air Quality Work
• This assures you are following Standard
Operating Procedures.
Sampling
• Sampled 24 homes
• For each home it took me 2 hours
• These are the survey forms that we used.
Sampling
• We log them on to our
Data Sheet.
Sampling
• Entered them on excel

This table is an interpretive guide for field based monitoring personnel. A professional health and/or safety specialist should be consulted
if there are any questions or concerns about this guidance, or if levels of concern are detected. The response strategy and corrective action
for measurements in the Orange and Red category may involve further health advisement or immediate removal from exposure.
Success Story
• When we first got the grant; I trained using our
office to collect air samples.
• We sampled 20 minutes and noticed that the
Carbon Monoxide was reading very high.
• We tested again for 24 hrs
• Both Daniel and I were experiencing headaches
and Nausea by the time we got off work; we
worked 7.5 hrs a day.
Carbon Monoxide
• Here is the Data that show the levels.
Daniel’s Office
Before CO AVG:
13.9 ppm
Daniel’s Office
After CO AVG:
0.1 ppm
Office
• Well we let our Council
know about our office.
• Since we received our
office in 2001, we have
had this monitor stove.
• Our maintenance
Department found out
that our seal on the pot
belly was worn, and was
releasing CO.
Mold Issues
• We had two homes that had
mold.
• We did further investigations
and educated them on their
HRV.
• Also, we tested the walls to
see how much moisture was
in the walls using a moisture
meter.
• Here are the results:
• East wall: 14-15°, 19-22°
• Interior wall: 16-17°, 21-19°
Problems Encountered
• When first using the Q-Trak, I didn’t follow the
Standard Operating Procedures-Had to re-do 8
homes. The re-do took 1 hour which I could
have been doing another home.
• When picking out how many homes should be
assessed; try to pick a lower number. I chose 50
homes of which I was only able to do 24 homes.
• Take lots of pictures; a picture can tell a story by
itself.
Conclusion
Most of the homes that we tested had a high CO²
which is Carbon Dioxide.
This tell us that most homes need to exchange
their air by opening windows or turning their
HRV up to exchange air or install M-80’s to
help exchange air. (homes that were built in
the 1970 or earlier)
Conclusion
• Most homes for PM 2.5 were in the yellow zone.
• This can be caused by smoke, burning fuels and
materials (carpet, dust mites, pet dander, ect.)
• It’s important to follow best practices for
operating wood stoves and heating appliances.
• Cooking, Indoor Smoking, and outside
conditions can contribute to PM 2.5 levels.
