Kula air monitoring ‘shows good air quality’

The Maui News

Air monitoring and sampling conducted in Kula between Nov. 8 and Nov. 15 shows good air quality, the state Department of Health reported on Thursday.

DOH is conducting air monitoring and air sampling in Kula as the U.S. Army Corps of Engineers conducts Phase II debris removal at fire damaged sites. Air sampling is conducted 24 hours a day for specific contaminants. After the sampling is completed, samples are sent to a certified laboratory for analysis, a news release said.

This sampling is being conducted to ensure that the USACE debris removal activities do not significantly impact air quality in the area of Kula and will continue throughout the debris removal work.

Other findings by the DOH include that there were no asbestos sample results above the laboratory's detection limit, indicating asbestos fibers were not present in the sampled air.

There were some heavy metal sample results that were below the laboratory's detection limit. Low levels of other heavy metals were detected, but all are below the public health screening levels indicating that the detections do not impact human health.

There were particulate matter screening levels that were elevated at one Kula sampling point which can be attributed to the operation of woodchippers and the spreading of woodchips on, and adjacent to, the property where the air monitor is located, the DOH said. The exceedances are not attributable to the USACE Phase II debris removal activities.

"DOH will continue both real-time air monitoring and air sampling to provide the community with data on whether debris removal or other activities are impacting air quality," said Deputy Director for Environmental Health Kathleen Ho. "It's important to remember that air monitoring and sampling are indicative of the ambient air quality at the time the samples were collected. Cleanup activities could cause hazardous dust and ash to become airborne. When in the impacted area where exposure risk is high, people should wear a well-fitting N95 or higher-rated mask and other personal protective equipment.

DOH and the U.S. Environmental Protection Agency have installed 53 real-time air monitors in Lahaina and Upcountry Maui--data from these monitors is available at https://fire.airnow.gov/. The real-time monitors measure for PM 2.5, particulate matter that is 0.0025 millimeters and smaller in size (about 30 times smaller than a human hair) that can be a component of ash, dust, smoke, and air pollution. 

Similar air sampling will be conducted by DOH in Lahaina when Phase II removal activities begin, the DOH said.
