Mitigation Assessment Team Report Hurricane Katrina in the Gulf Coast Building Performance Observations, Recommendations, and Technical Guidance FEMA 549 / July 2006 Appendix I. Description of Sampling and Analytical Methods As discussed in Chapter 8, samples of materials were collected from a number of flood-damaged buildings. Due to the damage to the materials in most of the buildings from the standing water, a large number of the samples were collected by breaking off a piece of already damaged wall finish. In other cases, a razor knife or drywall saw was used to cut through the surfaces and extract suitably sized samples. All bulk samples were then double sealed in plastic bags for transport to the Wonder Makers office in Kalamazoo, Michigan. Samples were then divided as necessary or prepared for submission to a laboratory for the requested analytical tests. I.1 Biological Bulk Samples I.1.1 Fungal Bulk Samples For each sample collected in the field, a laboratory procedure was necessary to prepare it for analysis for mold, and particulates. The bagged samples were carefully opened under controlled conditions and visually examined. Any visibly suspected biological contamination was captured for analysis by using a commercially available Air-O-Cell cassette connected to a high volume vacuum pump. The pump/cassette sampling apparatus was calibrated to 15 liters per minute (lpm) according to the manufacturer’s specifications. The cassette was then carefully hovered over the surface to collect particles from the visibly impacted areas. Sample analysis was conducted in conformance with Wonder Makers Environmental’s written analytical standard operating procedures, using light microscopy techniques. A minimum of 15 percent of the sample trace area was analyzed for each category of particulate (fungal spores, fibers, and opaque particles) identified, with fungal types identified to genus level when possible. An additional 12 to 17 percent of the sample was qualified to improve the accuracy of the analysis, noting any bioaerosols that were not quantified. For sample preparation, the collection slide was removed from the cassette, mounted under a cover slip, media side up, with Calberlas staining solution, and analyzed by direct microscopic examination at 1,000 times (1,000x) magnification with immersion oil used to connect the microscope objective to the cover slip. Sample results were reported as identified fungal spore types and presented in order of preponderance. If no spores were detected or observed during analysis, the result was reported as below minimum detectable limits (BMDL). I.1.2 Bacterial Surface Swab Samples As noted in the previous section, the bagged samples had to be prepared for submission to the laboratory. Each bag was carefully opened under controlled conditions and visually examined. Any visibly-suspect biological contamination was captured for analysis by using a commercially available sterile swab. These biological swabs were collected from various surfaces to yield quantitative and qualitative amounts of viable bacterial organisms. Sterile biological swabs and collection ampules containing a general transport medium were provided by a commercial manufacturer. Samples were collected based on a 2-inch by 2-inch template yielding 4 square inches of sample area. Samples were collected by wetting the cotton end in the transport medium and then rolling the swab completely across a surface to bring the entire surface of the swab into contact with the measured surface area. Disposable templates with predetermined dimensions were used to define the sampled area, which was then recorded on the sample collection log. The inoculated swabs were then inserted into the ampules and placed into a cooler containing fresh ice packs for overnight shipment to Aerotech Laboratories, Inc., in Phoenix, Arizona, for sample analysis. Cultures were propagated on standard blood agar medium for enumeration. Aerotech Laboratories is a recognized Environmental Microbiology Proficiency Analytical Testing (EMPAT) and Environmental Microbiology Laboratory Accreditation Program (EMLAP) certified laboratory. Sample results were reported as colony forming units per square centimeter (cfu/cm squared). I.2 Chemical Samples Following preparation of the biological bulk samples and biological surface swab samples, the remaining sample materials were forwarded to Clayton Group Services in Detroit, Michigan. If enough sample material was present, the samples were divided and prepped for numerous chemical analyses. As authorized by the Building Engineering Sciences and Technology Team (BESTT), samples were analyzed using EPA methods for organochlorine pesticides, PCBs, diesel range organics (DROs), and 13 common heavy metals. The information was recorded on the chain of custody and collection log and sent with the samples to Clayton Group Services. I.3 Sampling and Laboratory Test Results The results of the various laboratory tests conducted on the material samples collected in the field are provided on the pages that follow. Please refer to the legends and notes listed at the end of this appendix when reviewing the sample results. 1.

This Louisiana Department of Environmental Quality (LDEQ) program is designed to provide guidance for contaminant levels in non-industrial soils based on values from the U.S. Environmental Protection Agency (USEPA) or estimated from other sources such as the LDEQ and health professionals. The RECAP screening standards are intended to be protective of children and adults in typical residential settings with long- term exposure (i.e., 30 years) and identify areas of concern. In addition to the screening standards, the following RECAP Management Option 1 (MO-1) standards are available for soils to determine if the contaminant levels require further evaluation.

Additional Details and Limitations Regarding Chemical Sample Results: According to Clay­ton Group Services, the quality control results associated with the samples were within acceptable limits and do not adversely affect the reported results, except as noted in the fol­lowing bullets. - Some samples and/or analyses had to be voided due to insufficient sample quantity. The entire sample had to be voided on Wonder Makers' samples 37 - 4, - 5 and -40. Mercu­ry, pesticides/PCBs and DROs were voided on Wonder Makers' samples 37 - , - , -37 and -38. Pesticides/PCBs and DRO were voided on Wonder Makers' samples 37 - 5, - , - and -48. - For Wonder Makers' samples 37 -0 to - , - 3 and - 4, the holding time for sample preparation for DRO and pesticide/PCB analyses was 5 days after sample collection; which exceeded the EPA’s recommended holding time by day. - For Wonder Makers' sample 37 -04, the spike recovery for zinc on the matrix spike duplicate (MSD) was 300%, above the statistical limit of 0%, due to matrix interfer­ence. The matrix spike (MS) recovery on this sample was within limits, at 07%. The MS/MSD recoveries on samples 37 -34 and -44 were all within acceptable limits for zinc. - For Wonder Makers' sample 37 -44, the matrix spike/matrix spike duplicate (MS/MSD) recoveries for mercury were 40% and 880%, above the statistical limit of 44%, due to matrix interference. However, the MS/MSD recoveries on samples 37 -04 and -34 were all within acceptable limits for mercury. n For Wonder Makers' samples 37 -0 , -04, -05 and -08, the results reported for the or­ganochlorine pesticide DDD are estimated and could be high, due to a high recovery of the continuing calibration verification (CCV) standard. The high CCV recovery was like­ly caused by the sample matrices. - n For Wonder Makers' Samples 37 -07, - 0, - 0, - 3, - , -35, -3 , and -4 through -47, the recoveries of the two surrogates (TCMX and DCB) for analysis of pesticides/PCBs were below statistical limits and lower reporting limits could not be achieved, due to matrix interference. - For Wonder Makers' Samples 37 -0 , -03, -05, -0 , -08, - 8, - 0, - , - 3, - 3 , -35, -3 , -45 through -47, -4 and -50, the lower reporting limit for pesticides/PCBs could not be achieved, due to limited sample quantity.
