3 1.0 Introduction and Objective of Post Remediation Verification Summit (Summit) conducted fungal post remediation verification (PRV) assessment for 845 W. Center Street, Pocatello, Idaho. Assessments conducted by Summit are performed by a Council-certified Microbial Consultant (Harr) or a Council-certified Microbial Investigator (Larango). Summit s professional staff is certified through the American Council for Accredited Certifications. This report provides the results of the April 2014 PRV assessment. This report is prepared for users experienced in indoor air quality assessments and technical terms are often not defined within the report. If the user desires additional technical information related to microbial and bioaerosol assessments, a short glossary, reference list and general discussion of fungal sample data evaluation, the information is provided on Summit s web site: The laboratory reports and sample chain of custody records are attached. 1.1 Project Background The building is an old historic (pre 1920s) three story brick sided building with a walk out basement on the east side and a below ground basement on the west side. The building contains hip style tile roofs on the north and south ends and a flat gravel type roof in the center section. The interior is wood framed with wall and ceiling substrates ranging from sheetrock, plaster, concrete, and drop down ceiling tiles. According to the building managers, Mr. Jim Morphey and Mr. Joe Roberts, the building experienced several roof leaks under the 2 nd floor flat roof area during heavy rains in August The roof leaks were causing water to drip through the ceiling, down walls, and wetting the carpets in several areas. The moisture caused water staining to ceiling tiles and walls and suspect fungal growth was noted in several locations by the occupants. The same rain events in August 2013 also caused flooding in the west basement of the building. The flooding wetted the carpet and lower walls inside the basement door, hallway, and adjacent rooms. Summit performed an initial fungal assessment with recommendations. Findings and discussions can be found in the Summit report dated October 8, 2013, Initial Fungal and Moisture Assessment with Recommendations for Corrective Action to Water Damage. 1.2 PRV Objectives and Overview of Environmental Sampling Strategy Post Remediation Verification (PRV) is conducted to document that the moisture source has been addressed and materials are adequately dry; that proper mold remediation has been completed; and that the area or building can be occupied or rebuilt using regular construction practices. The level of effort and specific tasks of the PRV will vary PRV Report Page 3

4 with the nature of the mold contamination, the concern related to potential future liability, resale concerns, and the risk of potential health effects. Another key criterion for proper restoration is that the occupants can live or work in the building and not have fungal related health impacts. Large or high-risk projects may require collection of surface and / or bioaerosol samples from various locations using similar methods. The bioaerosol results can be compared to assess if any locations appear to have an amplification of the microbials tested (ACGIH, 1999; IESO, 2002); damp building marker type molds, or if the locations have similar organisms and concentrations; or if the indoor locations are similar in composition to the normal or expected outdoor seasonal bioaerosol. The different bioaerosol sampling methods have different bias and benefits, and the indoor environment professional must understand these issues when interpreting the sampling results (AIHA 2005, AIHA, 1996; ACGIH, 1999; Institute of Medicine, 2004; EPA, 2001). Environmental sampling should be conducted when it adds value and then it needs to address a specific hypothesis where the decision criteria should be clear prior to conducting the field sampling. Remediated areas should at least be returned to a Condition I conditions (see IICRC S520). Site specific conditions will influence fungal sample results and professional judgment needs to take all factors into consideration during interpretation. Surface fungal samples are generally collected (1) to document spore and fragment levels on cleaned or remediated surfaces (Condition 1, IICRC 2008); (2) to assess if excessive settled spore levels are present in non-affected areas or on building contents (Condition 2, IICRC 2008); and (3) to document fungal source areas (Condition 3, IICRC 2008). Tape samples are taken using a laboratory-provided tape lift kit. Surface swab samples are collected by swabbing an approximate 1 square inch area, using a laboratory-supplied, sterile swab with Butterfield s buffer solution. Surface swab samples can be cultured for representative viable fungi. Bulk samples can be collected; however they are not usually the preferred method for remediation PRV. Surface dust or carpet dust can also be collected to evaluate fungal remediation. Non-porous surfaces should generally be zero or at below 20 to 30 / cm2 spores of mixed types; semi-porous surfaces like wood should generally be below 50 to 100 spores /cm2 of mixed types; porous contents impacted by secondary contamination should not have dust with dominant fungal types which were amplified / present prior to remediation and dust results should reflect to local normal fungal ecology. Comparative indoor / outdoor air sampling between locations should indicate typical regional and seasonal outdoor fungal types and levels or better indoors because the affected area was remediated under controlled conditions. Site specific conditions must always be considered because indoor air spore types and levels will vary with the recent or current outdoor conditions. For example, winter snow cover often makes outdoor levels very low. Indoor A/P and Cladosporium concentrations should generally be ~ 20 to 100 PRV Report Page 4

5 spores / m3, given the initial assessment results for the area and time of year. No or very few Stachybotrys or other water indicator fungal spores should be present in indoor air samples, unless they are also observed at similar levels outside. Culturable samples add value if resources are available. 1.3 Summit Scope of Work Summit was retained to evaluate the mold remediation project and verify that the remediation work was complete and that building conditions were returned to normal environmental conditions. The project Scope of Work and budget establish the building areas evaluated and the number and type of environmental sampling that can be collected and analyzed. This PRV assessment included inspection of the 2 nd floor and west basement remediated areas only. A multi-sensorary and physical evaluation are completed for the remediated area. Summit collected limited fungal surface and air samples to assist in documenting satisfactory remediation completion and the current indoor fungal levels. 2.0 Multi Sensory and Field Measurement Observations and Findings Summit performed a progress visit on November 27, 2013 to assess the remediation progress and containment effectiveness. During the progress report; - containment in the west basement affected area appeared to be negative and vented satisfactorily. - the basement remediation appeared to be progressing satisfactorily with wood moisture readings below 12% in all areas tested. - the second floor remediation was still undergoing containment preparation. The Final PRV assessment included an evaluation of the remediated center 2 nd floor and the west basement areas. Field measurements include wood moisture, relative humidity, and temperature. The pertinent findings and improvements to the building are: PRV Report Page 5

6 2.1 Dampness and Moisture Source The basement moisture was caused by pine needles blocking the floor drain in the west basement entry access area. This drain has since been cleared and better management to keep clear is planned to prevent this problem in the future. The 2 nd floor moisture was caused by roof leaks from the old flat gravel type roof over this area. This roof has since been replaced with a membrane roof to repair this problem. There does seem to be excess water that still collects on the north side of this roof, which does not appear to be correct. Recommend having roofer reassess / buildup this area for proper drainage. During the PRV assessment indoor temperatures (65 o F to 72 o F) and humidity (25% to 35%) were within normal ranges and moisture readings collected in wood framing members (low to 9%). and sheetrock (low to 0.1%) were within normal ranges. PRV Report Page 6

7 2.2 Fungal Growth Removal and Cleaning The following is a summary of some of the remediation tasks that were performed as observed and according to interviews with the remediation contractor: Prior to remediation containment was constructed around the affected areas. Penetrations in the contained area were sealed (holes in walls, vents, piping, etc.). PRV Report Page 7

8 Areas to be remediated were placed under negative air using HEPA air scrubbers exhausted to the exterior and monometers were used to ensure negative pressure was achieved. Lower 2 feet of sheetrock was removed and in some cases the whole wall of sheetrock was removed in remediated areas. Stained ceiling tiles in the 2 nd floor remediated area were removed, the area ceiling void area inspected for fungal impacts, remediating any suspect fungal areas, and then sealing the entire ceiling with plastic. Sealing with plastic was done due to the age of the building and multiple ceiling substrates (i.e. concrete / plaster type ceiling, wood ceiling, acoustical tile ceiling, drop down ceiling) to ensure dust in the ceiling area from the old pre 1900 building did not interfere with the remediation. PRV Report Page 8

9 The affected 2 nd floor area and basement was remediated by aggressively cleaning and HEPA vacuuming and then cleaning with an anti-microbial and treating with Concrobium, an anti-microbial treatment. During Summit s final PRV assessment, there was no visible mold, no excess remediation dust, or mold type odors in the impacted areas. Judgmental based environmental samples (surface and air) were collected to provide additional information and document conditions at the time of the PRV assessment. 3.0 Environmental Fungal Sampling and Findings 3.1 Overview of Sampling Methods Surface tape samples are taken using a laboratory-provided tape lift kit. The tape was removed from the backing, placed on the sample area, and lightly pressed. The tape was removed using steady force and applied to the microscopic slide provided in the kit. When collected, surface swab samples are collected by swabbing an approximate 1 square inch area, using a laboratory-supplied, sterile swab with Butterfield s buffer solution. Surface swab samples can be cultured for representative viable fungi. Airborne fungi spore samples were collected using a high volume air-sampling pump. fungal spore samples were collected through Allergenco D microbial spore trap cassettes supplied by the laboratory with flow rate set at approximately 15 liters per minute for five minutes, or a total volume of approximately 75 liters of air. Airborne culturable fungi samples are collected within the environmental air on Malt Extract Agar (MEA) plates through an Andersen N-6 sampler with the flow set at approximately 28.3 liters per minute for five minutes, for a total volume of approximately liters of air. Culturable results are reported as Colony Forming Units (CFU) and CFU/cubic meter of air. Not all viable fungi will culture on the MEA plates due to various reasons. A key benefit of culturable fungi is the ability to distinguish between Aspergillus and Penicillium types. The samples were placed into sealed plastic bags with an appropriate sample identification number and submitted for analysis to EMSL Analytical, Inc., Phoenix, Arizona. EMSL is an accredited laboratory in the Environmental Microbiology Laboratory Accreditation Program (EMLAP). Samples were managed under Chain of Custody and usually shipped next day delivery to EMLab P&K. Sample collection and management was completed in a manner generally conforming to Standard Practices PRV Report Page 9

10 established by the Indoor Environmental Standards Organization (IESO) 2002 and the AIHA, 1996 and During this final PRV assessment, 8 surface tape, and 14 fungal air (8 total spore and 6 culturable) samples were collected for analyses. The attached Chain of Custody lists the final PRV samples and their locations. Below is a summary of samples collected.

Condtion 2 NA NA 3.2 Laboratory Results and Interpretation The report user should understand that single event bioaerosol sampling only documents the conditions measured at the time and location of sample collection. Fungal aerosols vary temporally and spatially due to numerous factors. A significant difference in spore levels and spore distribution between sample locations is often needed to document that air quality is truly impacted by an indoor source of fungi. Detailed visual observation and bulk and surface sampling of suspect building materials should also be used to evaluate a complaint building or room. Microscopic Screen and Fungi Identification Surface Tape Eight surface tape samples were collected to evaluate the remediated areas. Myxomycetes/Periconia/Smut were the most common and highest level of spores found indoors. The top of the basement mechanical room electrical panel contained medium dust (T ), which was the only area with higher than low to no mold. Myxomycetes/Periconia/Smut spores are common mold spores found in dust. This sample contained the highest level Myxomycetes/Periconia/Smut spores (289 spores/cm 2 ), however, not unusual for the dust content. Recommend properly cleaning the top of the electrical panels in this area upon remediation contractor equipment collection and demobilization. PRV Report Page 13

14 Summit interprets all of the other tape samples collected as unremarkable with normal to low fungal spore levels. See attached laboratory reports and chain of custody. Fungal Spore, Mycelia, and Pollen Counts Air During the PRV the weather was cool with rain and some snow during the day. Snow and rain may cause outdoor spore levels to be low. Eight total-fungal spore and fragment samples were collected and compared to two outdoor locations. Air is pulled through the spore trap device and spores and other airborne particles are impacted on the collection adhesive. The method is biased toward larger spore sizes. The analysis is by direct microscopic examination and does not include culturing. A typical mix of common mold types was found in the six indoor samples. These same types and levels (per M 3 ) were generally indentified in the outdoor air. The 2 nd floor north entance sample (N ) contained 1 raw count or 10 spores/cm 2 of Stachybotrys spores and 2 raw count or 90 spores/cm 2 of Curvularia and none were found outdoors. This area is outside the remediated contained area and in an area that was not accessed. These are moisture indicating mold types, however, these levels are not considered significant and may be due to the age of the building. Summit interprets the limited fungal spore /M 3 data as acceptable given project observations. The dominant outdoor mold types were similar to the dominant indoor types. Raw spore counts of 1 to 3 are generally considered trace and not significant in terms of an indoor amplification of mold growth. Fungal Air Culturable Analysis 25 degree C Summit interprets the culturable fungal air CFU / M 3 data as low levels for the time, location, and season of the sampling. The total culturable fungi CFU / M 3 were lower in the building than outdoors and generally consistent with the total spore air data. The various indoor locations had reasonably similar fungal levels and types. Raw colony counts of 1 to 3 are generally considered trace and not significant in terms of an indoor amplification of mold growth. 4.0 Summary of Key PRV Findings The key findings of the PRV assessment are: Moisture sources appeared to be corrected. All remediaiton work was completed using proper containment and HEPA filtered negative air. Exhaust air was directed outdoors. Wood and sheetrock moisture readings were acceptable in all areas tested. PRV Report Page 14

15 Surface and air fungal samples were collected to document normal building conditions. There does seem to be excess water that still collects on the north side of the roof, which does not appear to be correct. Recommend having roofer reassess / buildup this area for proper drainage 5.0 Conclusions Summit conducted the fungal PRV assessment in April The water / moisture sources were addressed.. All the building materials in the wetted areas, which were tested by Summit, had been removed or were adequately dry (see above for additional details). The contractor conducted the mold remediation under controlled conditions using proper procedures. During Summit s final PRV assessment, there was no visible mold, no remediation dust, or mold type odors in the impacted areas. Environmental surface and air fungal sampling indicates that the indoor locations sampled were normal fungal types and concentrations at the time of sampling (similar to or lower than seasonal outdoor types and concentrations). The mold remediation in the Scope of Work affected areas of the building has been completed consistent with the guidelines currently accepted in the United States by government agencies and relevant industry organizations. As with all buildings, continued attention to conditions that might allow microbial growth must become part of the long-term strategy. Maintenance by the owners should include routine inspections and prompt response to problems; adequate preventive maintenance of the HVAC system and plumbing; and adequate housekeeping including proper and routine cleaning. New leaks or flooding may create excess building moisture that may result in new fungal growth, if not properly corrected. PRV Report Page 15

Description of Analysis EMSL Order: Customer ID: Collected: Received: Analyzed: SUME85 4/01/2014 4/03/2014 4/09/2014 Analytical Laboratory EMSL Analytical, Inc. (EMSL) is a nationwide, full service, analytical testing laboratory network providing Asbestos, Mold, Indoor Air Quality, Microbiological, Environmental, Chemical, Forensic, Materials, Industrial Hygiene and Mechanical Testing services since Ranked as the premier independently owned environmental testing laboratory in the nation, EMSL puts analytical quality as its top priority. This quality is recognized by many well-respected federal, state and private accrediting agencies, such as AIHA s EMLAP and EMPAT programs, and assured by our high quality personnel, including many Ph.D. microbiologists and mycologists. EMSL is an independent laboratory that performed the analysis of these samples. EMSL did not conduct the sampling or site investigation for this report. The samples referenced herein were analyzed under strict quality control procedures using state-of-the-art microbiological methods. The analytical methods used and the data presented are scientifically and legally defensible. The laboratory data is provided in compliance with AIHA policy modules and ISO guidelines for the particular test(s) requested, including any associated limitations for the methods employed. These data are intended for use by professionals having knowledge of the testing methods necessary to interpret them accurately. Air Samples - Spore traps: Spore traps are commercially available sampling devices that capture airborne particles on an adhesive slide. Air is pulled through the device using a vacuum pump. Spores, as well as other airborne particles, are impacted on the collection adhesive. Using spore trap collection methods has inherent limitations. These collection methods are biased towards larger spore sizes. The analysis for total spore counts is a direct microscopic examination and does not include culturing or growing the fungi. Therefore, the results include both viable and non-viable spores. Some fungal groups produce similar spore types that cannot be distinguished by direct microscopic examination alone (i.e., Aspergillus/Penicillium, and others). Other spore types may lack distinguishing features that aid in their identification. These types are grouped into larger categories such as Ascospores or Basidiospores. Fungal spores are identified and grouped by morphological characteristics including color, shape, septation, ornamentation, and fruiting structures (if present) which are compared to published mycological identification keys and texts. EMSL reports provide spore counts per cubic meter of air to three significant figures. Please note that each spore category is This report has been prepared by EMSL Analytical, Inc. at the request of and for the exclusive use of the client named in this report.

Due to rounding and the application of three significant figures the sum of the individual spore numbers may not equal the total spore count on the report. EMSL does not maintain responsibility for final volume concentrations (counts/m3 ) since this volume is provided by the field collector and can not be verified by EMSL. EMSL analyzes spore traps using phase contrast microscopy. There is a wide choice of collection devices (Air-O-Cell, Micro-5, Burkhard, etc.) on the market. Differences in analytical method may exist between spore trap devices. Spore trap results are reported in spores per cubic meter of air. Due to the other airborne particles collected with the spores, EMSL reports a background particle density. Background density is an indication of overall particulate matter present on the sample (i.e. dust in the air). High background concentrations may obscure spores such as the Penicillium/Aspergillus group. The rating system is from 1-5 with 1 = 1-25% of the background obscured by material, 2 = 26-50%, 3 = 51-75%, 4 = 76% - 99%, 5 = 100% or overloaded. A background rating of 4 or higher should be regarded as a minimum count since the actual concentrations may be higher than those reported. EMSL will not be held responsible for overloading of samples. Sample volumes are left to the discretion of the company or persons conducting the fieldwork. Skin fragment density is the percentage of skin cells making up the total background material, 1 = 1-25%, 2 = 26-50%, 3 = 51-75%, 4 = %. Skin fragment density is considered an indication of the general cleanliness in the area sampled. It has been estimated that up to 90% of household dust consists of dead skin cells. 2.
