Mold Remediation Testing Results

The following mold spore test analysis were performed at a client’s home in Cheltenham, Maryland. Alfred Hawkins, Mold Medics’ commercial mold remediator, by and through Millman Systems had the results of tested the residence three times – prior to remediation on April 14, 2012, 10 days after remediation on April 24, 2012 and 5 months subsequent to remediation on September 11, 2012. Below is a brief explanation of the meaning of the spore counts and the results from Hayes Microbial Consulting, an independent testing company.

From Hayes Microbial Consulting: Indoor / Outdoor Comparisons: There are no national standards for the numbers of fungal spores that may be present in the indoor environment. As a general rule and guideline that is widely accepted in the indoor air quality field, the numbers and types of spores that are present in the indoor environment should not exceed those that are present outdoors at any given time. There will always be some mold spores present in “normal” indoor environments. The purpose of sampling and counting spores is to help determine whether an abnormal condition exists within the indoor environment and if it does, to help pinpoint the area of contamination. Spore counts should not be used as the sole determining factor of mold contamination. There are many factors that can cause anomalies in the comparison of indoor and outdoor samples due to the dynamic nature of both of those environments.

On April 14, 2012, prior to mold remediation, the mold spore count in the client’s basement for Aspergillus/Penicillium was 74,667 or 99.3% of the total. Hayes Microbial Consulting rated the basement as having a mold spore count “significantly higher than the outside air” which was 267 or 31.3% of the total.

The Cladosporium count in the client’s basement was 533 or .07% of the total. Hayes Microbial Consulting rated the basement as having a mold spore count “slightly higher that the outside air” which was 480 or 56.3% of the total.

From Hayes Microbial Consulting:

Aspergillus/Penicillium Adverse Health Effects: Known to be allergenic and many species also produce mycotoxins and carcinogens. They are a common cause of extrinsic asthma and hypersensitivity pneumonitis. Many species are opportunistic pathogens and are known to cause sinus lesions, ear infections, respiratory infections, and invasive systemic disease. Aspergillus species are the most common filamentous mold to cause infection and disease in humans.

Cladosporium Adverse Health Effects: Cladosporium species are rarely pathogenic to humans, but have been reported to cause infections of the skin and toenails. Prolonged exposure to elevated spore concentrations can elicit chronic allergic reactions leading to hypersensitivity pneumonitis, asthma and allergic rhinitis. Prolonged exposure to spores may lead to suppression of the immune system which allows other opportunistic viruses and bacteria to infect the host. Cladosporium species produce no major mycotoxins of concern, but do produce volatile organic compounds (VOCs) associated with odors.

After remediation, on April 22, 2012, the mold spore count in the client’s basement for Aspergillus/Penicillium was 2987 or 77.2% of the total. Hayes Microbial Consulting rated the basement as having a mold spore count “significantly higher than the outside air” which was 533 or 7.2% of the total.

The Cladosporium count in the client’s basement was 373 or 9.7% of the total. The outside air was then 1120 or 15.1% of the total.

On September 11, 2012 – five months after mold remediation – the mold spore count in the client’s basement for Aspergillus/Penicillium was 120 or 8.7% The outside air spore count was 27 or 20.0% of the total.
