Xtremes 30 Steps for Successful Remediation Project
STATE REQUIRED MOLD REMEDIATION STEPS
Pre-remediation visual inspections and testing should be conducted by an environmental consultant or third party consultant. These professionals should be
considered the architects of the remediation project. Test samples taken during the pre-remediation walk-through should be sent to an independent certified laboratory. (Independent refers to
independence of ownership or business relationship to the remediation contractor. The environmental consultant should develop a pre remediation report including recommendations of areas to be
remediated based on analysis of test sample results supplied by a certified laboratory and the environmental consultant’s visual observations of the site. A qualified remediation contractor
should conduct a site walkthrough. The contractor should review the pre remediation report submitted by the environmental consultant. The remediation contractor should develop a thorough
scope of work and bid outlining methods and procedures, as per industry standards and guidelines, to rectify microbial issues outlined in the environmental consultant’s pre remediation report.
The environmental consultant should review the contractor’s scope of work to ensure that the scope of work incorporates all of the recommendations outlined in the pre remediation report.
The remediation contract should be signed and a date for the remediation work should be scheduled. The environmental consultant should be contacted and advised of the remediation
schedule. This enables the environmental consultant to check on the remediation project in progress and to schedule the post remediation verification testing. (PRV) Upon starting the
remediation project, the contractor should install poly isolation barriers to contain specific areas where mold work is to proceed. Place isolated areas under negative air pressure using
micro traps with HEPA filtration. Before any remediation work begins, workers should dress in proper PPE (Personal Protective Equipment) before entering into isolated remediation areas.
Remove contents in isolated areas to be cleaned offsite or stored. Contents should be poly wrapped prior to exiting isolated areas. Remove and dispose of non-salvageable
contents. Such contents should be poly wrapped before exiting the containment area. Protect any remaining contents in isolated area. Conduct gross demolition following proper
procedures. Conduct gross clean-up. Any items removed from isolated areas during gross clean-up must be poly wrapped prior to removal from isolated area. Sand, wire brush, or
sanitize specific areas where surfaces, primarily wooden structural surfaces, have been stained due to microbial growth.
HEPA vacuum all surfaces within the contained area, HEPA vacuuming should be conducted from top to bottom, from the point furthest from the negative air machine to the point closest to the negative
air machines. (Surfaces within the isolated area include any contents within the isolated area) After initial HEPA vacuuming and prior to contact wet wiping, introduce fresh air into the
isolated area as part of the negative air supply. Clean all surfaces within the isolated area by contact wet wiping. Environmental consultants may recommend the use of sanitizer or detergents
like tri-sodium phosphates, for contact cleaning. HEPA vacuum all areas within the isolated containment again. Apply fungicidal encapsulate to areas designated in the scope of
work. (The environmental consultant may want to inspect surfaces prior to the application of fungicidal coatings. Environmental consultant should be notified as to completion date of
project in order to schedule post remediation verification testing. Sometimes, a third HEPA vacuuming may be required to remove particulate generated from fungicidal coating
application. Change configuration of negative air from micro traps to air scrubbers. Isolated breach ways should be sealed during this process. A minimum of 200 air exchanges should
occur during air scrubbing prior to post remediation verification testing. This usually takes 8 to 12 hours. Post remediation testing should occur within 72 hours of completion of air
purification. The post remediation verification testing should be conducted by the original environmental consultant. Post remediation test sampling methods should match those used in pre
remediation test sampling. Test sampling methods that vary can be used but if such sample results do not pass post remediation verification criteria, the scope of work may have to be
expanded. Post remediation test samples are then sent out to an independent certified laboratory. Visual observation and analysis of the post remediation test sampling results are
used to determine if the remediation project is successful. Visual observation conducted would confirm that the space is absent of any loose particulate, and the mold colonization has been
properly remediated. Test sample PRV would show that either no mold or rare amounts of mold were on tested surfaces, and that air-ocell samples maintained spore levels at or below baseline
samples. The remediation contractor should be responsible, as part of the original contract, to remediate areas until they pass post remediation verification testing. A post
remediation verification report should be generated by the environmental consultant clearing the isolated remediated areas, and confirming that the mold remediation project has been
