Re: 22 River Terrace, NYC
Dear Mr. Walsh,
GCI Environmental Advisory, Inc. collected ambient air samples within all of the apartments as well as various common spaces within the above referenced building during September 21 - 25, 2001.
Air sampling was conducted within the building utilizing 0.8 u, MCE sampling cassettes employing high volume air sampling pumps during "normal" building activities. A minimum of Nine Hundred (900) liters of air was collected to provide a detection limit below 0.01 f/cc (fibers per cubic centimeter). All samples were pre- and post-calibrated by means of a precision rotometer that had been calibrated with a primary standard. Sampling blanks were collected and submitted with each group of samples analyzed. Air sample analysis was according to NIOSH Analytical Method 7400 with results reported as fibers per cubic centimeter (f/cc). Laboratory Analysis performed by an ELAP approved and NIOSH PAT proficient laboratory.
Laboratory analysis indicated airborne levels either below the current recommended "Clearance Air Criteria" of 0.01 fibers per cubic centimeter (f/cc) of air according to Phase Contrast Microscopy (PCM) or well below the Environmental Protection Agency (EPA) standard for Transmission Electron Microscopy (TEM) of Seventy (70) Structures per cubic centimeter (Stuct/cc).
Should have any questions or need additional information, please contact me at you
