DocuSi n Envelope ID: B94F2D40-3B3C-47A7-86C2-6F1 B4F92C62C <br /> E tnvironmentai 3omuons uroup <br /> Leading people,companies and communities to live, Report with Protocols for Re m e d i a t i o n <br /> work and prosper in a sustainable environment. <br /> Assessment Protocol: <br /> This report is based upon a non-destructive visual assessment, laser particle detection and material samples collected on <br /> October 5, 2018. Components to be sampled were selected by the investigator. As mold can spread quickly under <br /> optimal conditions, both visual mold and spores can vary from day to day. For this reason, Environmental Solutions <br /> Group certifies that the mold counts contained in this report are valid on the date of inspection. <br /> Protocols for remediation are valid for a period of thirty(30) days from the date this report was issued. Furthermore, <br /> Environmental Solutions Group (ESG) certifies that material inside the building contains the spore counts as indicated in <br /> the report. ESG is not able to certify that mold does not exist in areas that were inaccessible during the inspection <br /> process or that mold spores are not present in the air of the building. Testing and analysis of this investigation only <br /> pertains to damage from moisture and mold, and this report is intended to be relied on solely by the client. ESG's <br /> liability is limited only to the fees paid by the client. <br /> Brief History(based upon information provided by the client and the onsite assessment): <br /> The two-level commercial building is located at 510 Meadowlands Dr., Hillsborough, NC. ESG was engaged to collect <br /> samples throughout the building. <br /> The building is currently occupied and was identified as being impacted by elevated humidity, moisture damage, and <br /> microbial contamination resulting from a lack of proper conditioning and moisture infiltration around the windows and <br /> lower level exterior walls.The occupants reported noticing a musty odor and suspect microbial growth was reported at <br /> the HVAC cassette units and on furniture in some of the offices. <br /> The client has requested an evaluation be performed so that ESG can develop a scope of work for remediation of <br /> identified environmental hazards relative to moisture damage. <br /> ESG's assessment of the property occurred on the afternoon of October 5, 2018. <br /> Methods• <br /> Moisture Meter: a Delmhorst 'Moisture Check' meter was used to test and verify the moisture content of building <br /> materials. The meter utilizes the principle of electrical resistance, and uses wood or other hygroscopic materials as an <br /> element in a circuit between two pins or electrodes that are inserted into the material. <br /> Surface Sampling for Laboratory Analysis: representative bulk surface samples were collected using a sterile swab. <br /> Results of the lab analysis are discussed below. <br /> Air Sampling for Laboratory Analysis: samples were collected using a Micro-5 cassette for a 25 Liter collection of total <br /> spores,viable and non-viable. A Buck L-5 sampling system was used for sample collection. ESG's Buck pumps are <br /> serviced and calibrated by the manufacturer and were calibrated prior to and during the assessment with a Zefon air <br /> flow rotometer. The sample collection locations were throughout the building, warehouse, and outdoors for <br /> comparison purposes. <br /> Environmental Solutions Group • 1000 N.
