Walt Baenziger has been a leader in providing
Home Environmental Services and Comprehensive Onsite Building Science Investigations
for homes and businesses in New England for fifteen years. Using sensitive equipment, laboratory analysis, and extensive
building systems knowledge, he can identify the causes of problems and guide clients in obtaining healthy indoor conditions.
In both residential and commercial settings, he provides a clear scientifically based understanding of the causes of Biological,
Chemical, or Particulate pollutions and the steps necessary to eliminate them. Many Indoor Air Quality problems are caused by excess moisture from water leakage or chronic high relative humidity and dew point issues. The EPA states that fungal development is suspected on materials that have been damp for 48 hours. A clear understanding of the physics and biology of an indoor ecosystem will allow the changes needed to maximize Indoor Air Quality. The growth of fungal material, Mold, is an increasing concern as buildings are tightened for energy conservation. The proper Remediation of biological materials must be accompanied by the reversal of the conditions that promoted the growth or the problems will reoccur. Please call with any Indoor Air Quality or Environmental questions or concerns, or to arrange for an investigation and consultation. 413-568-7701 Biological Pollutant Identification, Including Mold and Bacteria: Sampling for laboratory analysis can include air, surface, or bulk sampling. Laboratory analysis of samples is done through direct microscopic examination of collected material or examination of cultured viable biological growth under controlled conditions in the laboratory. The laboratory data can be helpful to the investigator for remediation planning and preventive recommendations. In addition, the scientific data can be helpful to the clients primary care physician in diagnosing and treating environmental illnesses or allergies. Many people have allergies to molds (fungus), dust mites, or animal dander. Chemical Pollutant Identification: Chemical samples are analyzed using Gas Chromatography or Mass Spectrometry to identify the particular constituents present in the subject environment. This can be helpful for clients with Multiple Chemical Sensitivity or where chemical offgassing is suspected indoors. There are now many more low or even no-VOC products available to the consumer. Radon: Radon is the second leading cause of lung cancer. The Surgeon General and the EPA recommend testing for radon and reducing radon in homes that have high levels. Fix your home if your radon level is confirmed to be higher than 4 pCi/L. Lower levels still pose a risk and can be reduced. If you smoke and your home has high radon levels, your risk of lung cancer is especially high. Remediation Planning: When the remediation of offending materials is required, the EPA recommends that a clear and appropriate plan be developed and carried out. This will ensure a successful outcome and provide for the protection of the occupants and the clean portions of the building. Containment and Personal Protection Procedures are critical in some cases, and mistakes can be costly. The EPA discourages the introduction of biocides (chlorine bleach), harsh chemical cleaners, or Ozone (ionization) as unnecessary and possibly harmful. The EPA and the IICRC have developed clear guidelines for removing Mold and other contaminants from occupied spaces. Ask the Expert!
