Monitoring Air Quality

To protect public health and the safety of workers onsite and the community where people live, work, and shop, Honeywell, under the supervision and at the direction of the EPA, implements an extensive air monitoring program. The Health and Safety Plan and the Perimeter Air Quality Monitoring Plan, which were reviewed and approved by EPA, are key parts of the cleanup. These documents are available at the Edgewater Public Library, 49 Hudson Ave., Edgewater, NJ 07020.

Components of the air monitoring program include:

  • "Real-time" Site Perimeter Monitoring - Daily "real-time" monitoring for dust and total volatile organic compounds (VOCs) is conducted during soil remediation using fixed and mobile air monitors around the perimeter of the site. Results can be found on the air monitoring map below. Data collected and analyzed for individual site contaminants at the perimeter are found here: Phase 1 (no tents), demolition, and Phase 2 (most work under the tents).
  • Offsite Air Monitoring - To protect public health where people live, work, and shop, air sampling of site contaminants is conducted in the surrounding community as well as at the site perimeter fence line. Data is collected and analyzed for individual site contaminants. Samples are collected daily for 24-hour periods from three locations in City Place and iPark, and one location in The Promenade, The Metropolitan, and Independence Harbor.
    • Daily air sample results are used to calculate a running project average. The running average is updated weekly as results become available. That average is then compared with the Risk Screening Level that EPA has set for individual chemicals.

    • Risk Screening Levels are based on conservative assumptions and assume “chronic” exposure - a resident being exposed to a chemical (e.g., through breathing it) for 24 hours per day, 350 days per year for 7 years (10% of an average lifespan of 70 years). For naphthalene, people would need to be breathing it at levels above the Risk Screening Level continuously for 7 years to be at an unacceptable risk level for adverse respiratory effects.
    • Because the Risk Screening Level is based on long-term exposure to a chemical, it should be compared against the running average of that chemical during the project, rather than individual daily results. Individual daily results are not an indicator of long-term exposure.
    • The graphs accessed above show the running averages of naphthalene concentrations over the life of the project compared to the project-specific Risk Screening Level for naphthalene, developed in consultation with EPA. Naphthalene is the only contaminant that historically has been observed above the Risk Screening Level; therefore, similar graphs have not been developed for other chemicals.
