PCB Remediation and Consulting

VERTEX’s technical staff can assist clients with identifying potential Polychlorinated Biphenyls (PCB) containing materials through sampling.  Depending on the extent of PCB containing materials as well as project scheduling, and ultimate project goals (renovation, demolition, change in use), VERTEX will consult with the client to determine the most cost-effective and timely approach to remediate the PCB waste. Our work is always performed in accordance with United States Environmental Protection Agency (EPA) regulations, no matter if it involves conducting Self Implementing Plan (SIP), Performance Based Remediation, or Risk Based Remediation.  VERTEX can also assist the client in navigating and interpreting specific regulations associated with testing, handling and disposing of PCB waste and act as a liaison between the client and the EPA regulators.

Indoor Air Quality Assessments

VERTEX’s expertise and highly skilled Certified Industrial Hygienists (CIHs), Certified Indoor Environmentalists (CIEs), and other technical staff coupled with our extensive knowledge of building sciences lend us the capability to develop specific assessment protocols to assist clients in determining the non-specific pollutant sources typically associated with Indoor Air Quality (IAQ) concerns. VERTEX designs each IAQ assessment on a case-by-case basis as no two IAQ issues are alike. Depending on the complexity of the IAQ concerns, VERTEX has the ability to utilize our in-house professional engineers, mechanical engineers, and HVAC experts to assess all aspects of a buildings functionality such as construction design, ventilation, intake and exhaust air ratios. Once suspected sources of the IAQ concerns are identified, VERTEX can assist the client with the implementation of measures to mitigate adverse sources and improve IAQ.
