Site Assessments
Environmental Site Assessments (Phase I & II ESAS (Environmental Site Assessment)) are regularly requested by our clients when they are taking into consideration buying, mortgaging, valuing, or selling their property. Commonwealth Tank works closely with owners or their agents prior the purchase or sale of a property to assure that potential environmental problems and considerations are well understood.

Indoor Air Quality Testing
We use a ground-up approach to perform Indoor Air Quality (IAQ) Assessment for our customer. Targeted building components are inspected for signs of water intrusion and mold growth. Any impacted areas are defined and remedial recommendations made based on the type of microbe and concentration present. We use a variety of microbial bulk and air-sampling techniques based on the assessment result to best quantify the potential microbes. Using this approach, we are able to quickly and cost-effectively identify factors that can impact overall air quality.
