Hall Environmental Analysis Laboratory received 1 sample(s) on 12/16/2020 for the analyses presented in the following report.

Andy Freeman

These were analyzed according to EPA procedures or equivalent. To access our accredited tests please go to www.hallenvironmental.com or the state specific web sites.

In order to properly interpret your results, it is imperative that you review this report in its entirety. See the sample checklist and/or the Chain of Custody for information regarding the sample receipt temperature and preservation. Data qualifiers or a narrative will be provided if the sample analysis or analytical quality control parameters require a flag.

When necessary, data qualifiers are provided on both the sample analysis report and the

QC summary report, both sections should be reviewed. All samples are reported, as received, unless otherwise indicated. Lab measurement of analytes considered field parameters that require analysis within 15 minutes of sampling such as pH and residual chlorine are qualified as being analyzed outside of the recommended holding time.

Please don't hesitate to contact HEAL for any additional information or clarifications.

ALS Work Order: 20120696 NARRATIVE: Analysis performed on FEI Tecnai TEM equipped with EDAX Octane T Plus Silicon

Drift Detector and Z2 Analyzer. Fiber morphology, selected area electron diffraction (SAED), and energy dispersive x-ray analysis (EDXA) used to determine species.

All sample collection is performed outside of ALS Cincinnati is therefore the sole responsibility of the client. Contact your local authority for information on method selection, sampling instructions, and reporting requirements prior to submission.

NOTICE: The EPA requires drinking waters from Public Water Systems (PWS) for EPA compliance be filtered by the laboratory within 48 hours of sampling.

Results cannot be reported to the EPA unless ALL information required by the EPA was provided via the paperwork submitted with the sample at the time it was received by ALS Cincinnati. Report revisions resulting from failure to provide the necessary information at the time of receipt will incur additional administrative fees. ALS is not responsible for late or inaccurate EPA reporting as a result of client sample collection errors or sample information omissions.

METHOD CODE: "EPA 100.2" refers only to drinking (potable) waters for EPA compliance filtered on 0.22µm pore sized MCE filters. "EPA 100.1" refers only to potable waters for EPA compliance filtered on 0.1µm pore sized polycarbonate filters. "ENV 005" refers to all non-potable waters regardless of origin, use, or method requested. All excess water samples are disposed after adequate filtration. Filtered samples are disposed after 60 days. TEM grids archived 3 years. Results apply only to portions analyzed.

SUMMARY: An AS of <0.2 MFL is desired for drinking (potable) waters, and an AS of <7 MFL is generally acceptable for non-potable waters. Whenever possible, a sufficient volume is analyzed to yield the desired AS based on the detection of one confirmed asbestos fiber in the total area analyzed. However, samples containing excessive suspended solids may require filtration of volumes too low to achieve the desired AS.

All water samples are analyzed at >10,000x magnification for asbestos fibers >10µm long. A minimum of 4 and maximum of 10 grid openings are analyzed regardless of the AS reached or the asbestos concentration detected. Representative EDXA spectra and/or photomicrographs are available upon request for an additional fee.
