The Cerro Grande FireOn May 4, 2000, National Park Service personnel ignited a prescribed burn at Bandelier National Monument, which escaped their control and was declared a wildfire on May 5th. It ultimately burned nearly 50,000 acres in and around Los Alamos, New Mexico. ImpactsCerro Grande Fire Impact SummaryA summary of fire impacts is now available. The first group of samples that may have been impacted by fire emissions was the biweekly particulate matter filters removed from our AIRNET samplers and replaced with new filters on May 9th or May 10th. It should be noted that this set of samples is generally designated as the May 8th, 2000, or the 000508 samples. To expedite analysis, these samples were hand-carried to the Wastren-Grand Junction Analytical Laboratory for normal biweekly analyses and additional isotopic analyses. In an effort to assess the impact of the fire, most filters were replaced at least one more time from May 10th through May 14th. Even though filters are normally used in the field to collect continuous two-week samples, the smoke from the fire was clogging the filters after several days. Therefore, we replaced the filters more frequently to ensure that we would have as much short-term ambient air quality data as feasible for the duration of the fire.
