Molds usually grow in damp places, behind walls, under floors, above ceiling tiles, and behind shower walls. Water is the key — without it, molds cannot grow, much less spread. When water is left to sit for even 24 hours, mold infestation begins. If water continues to sit and areas become completely saturated, the ideal environment is created for toxic molds to grow, such as Stachybotrys.
What Causes Mold?
Molds may grow at high levels indoors in a home or building, if the right environmental conditions exist. Factors that influence mold growth include: moisture sources, improperly ventilated bathrooms, high humidity levels, broken pipes and washing machine hoses, floods, leaking roofs, leaking
exterior siding products, and leaking windows and doors.
How Common Are Household Molds?
A 1994 Harvard University School of Public Health study of 10,000 homes in the United States and Canada found half had "conditions of water damage and mold associated with a 50 to 100% increase in respiratory symptoms."
What If Mold Is Found?
MDS does not provide remediation services as it is a conflict of interest. However, the underlying cause of water accumulation must be rectified or fungal growth will recur.
What Is Remediation?
The purpose of mold remediation is to remove and/or clean contaminated materials in a way that prevents them from spreading mold to uncontaminated areas. It is necessary to clean up mold contamination, not just kill the mold.
Questions To Ask Before Remediation:
- Has the source of moisture been fixed?
- Are there existing moisture problems in the building?
- Have building materials been wet more than 48 hours?
- Are there hidden sources of water or is the humidity too high?
- Is there a musty or moldy odor in the building?
- Are building materials or furnishings visibly damaged?
Air Sampling: Air samples test for viable (living) mold. Testing for viable mold is done by placing the sample onto agar culture medium that supports the growth of the organism(s) in question and allows identification of the species and level of contamination. When colonization occurs one mold has overtaken your entire home. Colonization is the formation of compact population groups of the same type of mold species. Air samples also test for nonviable (dead) mold. Testing for nonviable mold is done by microscopic examination of the sample to identify fungal and non-fungal particles that may be allergenic to individuals.
Bulk Sampling: Bulk samples include, but are not limited to, chunks of carpet, insulation, and wallboards. Bulk samples are collected from visibly moldy surfaces by scraping or cutting materials with a clean tool and placing the sample into a petri dish for mold testing.
Surface Sampling: Surface samples are collected by wiping a measured area with a sterile swab or by lifting a sample with bio tape. The surface sample is cultured and then placed into a petri dish. After allowing 3 - 7 days for the samples to show visible fungal growth, the petri dish is inspected by a lab technician under a microscope so that the fungi can be removed and identified by species.
Sampling Is Necessary Where:
- Health Concerns
Are a Problem
- The Source(S) Of the Mold Contamination Is Unclear
Sampling Allows Us To:
- Locate the Source Of
- Identify Some Of the
Mold Species Present
- Differentiate Between
Mold & Soot or Dirt
