Thank you for choosing NAL East Environmental Services for your Post Remediation Assessment (PRA). Sampling helps determine if the work was done correctly by getting scientific documentation of what’s present in the property. If sampling was conducted before the remediation was conducted, we will compare the levels from before the remediation was done with the results from this evaluation as well as using all the industry recommended guidelines. If it was a fire and/or natural disaster, we will use those industry guidelines for the inspection and sample results That way you are assured of what’s present after the remediation work was completed without any hidden obstacles and the property can be certified, CLEARED.

The goal of remediation is to remove or clean contaminated materials in a way that prevents the emission of fungi and dust contaminated with fungi from leaving a work area and entering an occupied or non-abatement area, while protecting the health of workers performing the abatement as well as the occupants.

The purpose of Post Remediation Sampling (PRS) is to provide a measure of assurance that that the property has been remediated correctly. This is done through sampling and visual inspecting the property. The moisture problem should have been completely fixed and all visual molds should have been removed. If the remediation was due to a fire and/or natural disaster, the sampling and visual inspection is extremely important because it verifies the levels inside the property to re-confirm acceptable clean-up. The property should be free of a musty odor and no airborne Stachybotrys atra should be present. In case of a fire, no black carbon, soot should be detected. Black carbon, soot sampling information will be forwarded to you in a separate attachment.  

This Post Remediation Assessment (PRA) and Post Remediation Sampling (PRS) inspection includes a complete visual inspection of all the entire property. Pictures are taken showing all of the remediated areas and you will get a copy of those pictures with your Post Remediation Assessment microbial results report.

The most important concern and our number one interest is protecting your liability. The Post remediation Assessment (PRA) certifies that all airborne concerns have been addressed and that the airborne levels are low and acceptable. The visual inspection also confirms that no visible issues were present. We protect your interest by confirming with sampling results and visual inspection that there are no issues now, which in turn, protects you once occupants move in. You will also have a certified certificate, a results report and laboratory results charts confirming acceptable levels. 

The Post Remediation Assessment (PRA) includes in-depth visual inspection of remediated areas and seven (7) total samples. 

If a smaller area was remediated, only (4) samples may only be needed. If only one area was remediated, then three (3) samples can be conducted. Our sample results will tell us what kind of molds are present and at what levels so we can determine if the levels have been significantly reduced or if no initial sampling was conducted, we can compare the levels to industry standard guidelines for post remediation assessments.  

All samples are submitted to EMSL Analytical, a fully accredited nationwide Laboratory. One outdoor air sample establishes a baseline for the comparative evaluation of the indoor samples. All inspections are strictly confidential and coded for your privacy. You will receive a comprehensive report of the Environmental Consultants’ findings during the inspection, as well as an analytical report written by the microbiology lab stating what kinds of molds are present and at what levels within 12 to 24 hours after the samples are received by the laboratory (EMSL). 

Keep in mind that every property has mold, it’s just a question of what kinds and how much. 

The EPA recommends that the kinds and concentrations mold spores should be similar inside to those found outside, once cleaning activities have been completed. It is highly recommended that new materials not be installed until post-remediation evaluation, and post-remediation verification (sampling) is done to indicate that installation is now appropriate.

The EPA recommends that the types and concentrations of mold spores should be similar inside compared to those found outside, once cleaning activities have been completed. It is highly recommended that new materials not be installed until post-remediation evaluation, and post-remediation verification (sampling) are done to indicate that installation is now appropriate.

The post-remediation acceptance criteria in the various trade associations and governmental guidelines are listed below:

The American Industrial Hygiene Association (AIHA) states that the indoor levels of airborne mold spores should be less than the outdoor levels. If the Post-Remediation sampling shows similar species and relative magnitudes indoors and outdoors, then the indoor levels would most likely be due to normal infiltration from the outside air. If the types of molds are not similar, or if indoor levels of a certain type of mold are higher than the outside levels, then this could indicate continued indoor amplification or remaining indoor reservoirs of spores from Post Remediation.

The Environmental Protection Agency (EPA), states that all visible mold, mold-damaged materials and moldy odors should not be present after the remediation work has been completed. The kinds and concentrations of mold and mold spores inside the property should be similar to those present in the outdoor sample. Also, people should be able to re-occupy the property without health complaints or physical symptoms.

The Occupational Safety & Health Administration (OSHA), and the New York City Department of Health (NYCDOH) use the same basic guidelines listed above.

If the results confirm that the airborne levels are acceptable, you will receive a certificate stating so.

If after the inspection is completed and the airborne results are still elevated, we will demand that the remediation company come back, at no charge to you and do additional cleaning which will be recommended by us in-detail based on your laboratory results. 

Post Remediation Sampling (PRS) will confirm if the work was conducted correctly because the levels should be significantly reduced and/or low and acceptable. We use four (4) different industry standards to determine if your current levels are acceptable.

The Centers for Disease Control and Prevention (CDC) state that some people are sensitive to molds. For these people, exposure to molds can cause symptoms such as nasal stuffiness, eye irritation, wheezing, or skin irritation. Some people, such as those with serious allergies to molds, may have more severe reactions. Severe reactions may include fever and shortness of breath. Some people with chronic lung illnesses, such as obstructive lung disease, may develop mold infections in their lungs.

NAL East only uses American Indoor Air Quality Council Certified Environmental Consultants. Our Certified Environmental Consultants go through constant schooling and certification updating throughout the year. 

NAL East currently follows the guidelines set forth by the United States Environmental Protection Agency (US EPA), the Delaware Department of Health (DEDOH), the New Jersey Department of Environmental Protection (NJDEP), the New York City Department of Health (NYCDOH), the Pennsylvania Department of Health (PADOH), and the California Occupational Health and Safety Administration (Cal-OSHA).

Please feel free to call us with any questions @ (877) 665-3837. Payment is due at the time of the inspection. All results are strictly confidential and coded for your privacy.  Again, you will receive your results within 12-24 hours after your inspection is completed. This will include results report, laboratory results charts, copies of your pictures and clearance certificate.
