The U.S. Environmental Protection Agency (EPA) Region 6 collaborated with the EPA Office of Research and Development in another passive ozone monitoring study during the summer of 2005. Using completely passive (i.e. no electric power required) sampling devices with nitrite coated filters, Region 6 state and tribal volunteers, along with interested lay people (e.g. retired farmers, 4-H Club members, master gardeners), will successfully deployed up to 30 passive ozone sampling sites around EPA Region 6.

The passive sampling devices for ozone produced excellent correlations with conventional continuous ozone samplers (.95-.97 for 24-hour samples) in 2004. Passive ozone sampling is very helpful in inexpensively (at about 20% the cost of conventional sampling) gathering large amounts of ozone monitoring data to help fill in data gaps and to screen new areas, including more remote rural areas.

Region 6 Tribes participating in this year’s passive ozone sampling include:

 

Osage Tribal Land (Osage County)
Pawnee Tribal Land (Pawnee County)
Cherokee Nation collocated with a continuous site (40-021-9002)
Cherokee Nation (Marble City, Sequoyah County)
Jemez Pueblo collocated with a continuous site (35-043-9004)
Zuni Pueblo (New Mexico)
Taos Pueblo (New Mexico)
San Pueblo Tribal Land (New Mexico)
