Indoor Air Investigation:

Fields Environmental provides knowledgeable and cost-effective solutions to indoor air quality (IAQ) issues.  Fields has numerous years of experience managing IAQ projects in a variety of commercial and residential properties.  Fields has staff who understand the exposure scenarios from IAQ issues resulting from temperature changes inside and outside the building, exterior air quality, and IAQ impacts due to operation of heating, ventilation, and air conditioning (HVAC) systems.  Assessment of IAQ through analytical testing, analysis, and remediation provides for healthy, clean, and safe places for living and working. Fields is familiar with the requirements and rules regarding the evaluation and remedies for IAQ issues as mandated by statewide agencies.     

IAQ can also be influenced by the process of vapor intrusion. Vapor intrusion is the process in which volatile chemical compounds from the soil or groundwater beneath a structure migrate through subsurface soils and into indoor air spaces. Vapors can enter a building through cracks in the building's foundation, and opening in utility lines.

Fields has led the the region in providing sophisticated, and cutting edge IAQ assessments though the utilization of electropolished, passivated stainless steel vacuum sampling devices, or SUMMA canisters.  Fields utilizes SUMMA canisters not only for their reliability, but also in the versatility of application.  Fields indoor air assessments can include both analysis of indoor air and sub-slab soil gas conditions.    


Mold Investigation:

Fields Environmental provides comprehensive and thorough inspections and testing services into potential indoor air quality (IAQ) issues resulting from mold.  Fields has staff who are able to conduct preliminary inspections, design sampling plans, conduct mold, sampling, and report results in a direct and concise manor.  Factors including outdoor and indoor temperature, and humidity as well as HVAC conditions are important in assessing the viability of airborne molds.  

Fields utilizes ambient air (AA) and Indoor Air (IA) spore trap sampling, surface mold sampling, and measures relative humidity and temperature in assessing IAQ in terms of mold conditions. The United States Environmental Protection Agency (USEPA) does not currently maintain regulations or standards for airborne mold contaminants and therefore mold concentrations are often reported in high, moderate, low, and absent concentrations and cannot be directly compared to specific criteria.
