Samples of precipitation such as rain, snow or sleet are collected at more than 25 stations across the U.S. Samples are collected using specially designed precipitation collection devices which funnel the precipitation into a bucket for transfer to a shipping container. EPA’s National Analytical Radiation Environmental Laboratory (NAREL) receives the…
Hourly emissions data files are available from the Clean Air Markets Division of EPA, collected as part of 40 CFR Part 75. The download location has changed in February, 2023. The new location is https://campd.epa.gov/data/bulk-data-files. Once on this new site, use the menu (at the left) and the Keyword search…
A few important items to note regarding the Pennsylvania Cancer Registry: PADOH’s Pennsylvania Cancer Registry is a statewide data system responsible for collecting information on all new cases of cancer diagnosed or treated in Pennsylvania. It is part of the National Program of Cancer Registries administered by the Centers for…
The first step of the site assessment process is known as a preliminary assessment (PA). This assessment gathers historical and other readily available information on site conditions and surroundings to evaluate whether the site poses a potential threat to human health and the environment and/or whether further investigation is needed…
The main question that EPA seeks to answer is whether the identified waste areas warrant consideration for placement of the Site on the National Priorities List (NPL) or Superfund List. In the first round of sampling, EPA collected surface soil samples (0-2 feet) from the landfill property, and surface water…
Screening levels are not the same as cleanup or action levels. An exceedance of a screening level indicates the need for additional evaluation, potentially including a site-specific risk assessment.
If the sampling data shows an exceedance of a screening level, EPA will consult with the site Toxicologist and the Agency for Toxic Substances and Disease Registry (ATSDR) to conduct a human health risk screening assessment to determine any potential threat to human health. EPA will also consult with the…
EPA uses all credible information available, including community input, regarding the boundaries and geographic areas of waste that may have been deposited or where contaminated soil may have been placed. The team selects its sampling locations based on those areas and consults historic aerial images that help depict those boundaries.
EPA is still conducting its investigation of the Norwood Landfill Site to determine if it should be placed on the National Priorities List (NPL), or Superfund List. Thus far, the data collected has not demonstrated that the site warrants placement on the NPL. Both the Folcroft and Clearview Landfills went…
The raw data and summaries that are still available (dating back to 1990) can be obtained from the web page https://www.epa.gov/air-emissions-inventories/pollutant-emissions-summary-files-earlier-neis. Starting with 2001 data, a more limited selection of summary files are available.
The former Glenolden Laboratory property located on South Avenue is a separate site. The previous owners conducted a voluntary cleanup pursuant to the Pennsylvania Department of Environmental Protection’s (PADEP) Environmental Cleanup Program, known as Act 2. Concerns regarding remedial actions conducted under Act 2 should be directed to PADEP as…
The EPA’s RadNet monitoring network is designed to track fluctuations in airborne radioactive particles. RadNet does not track non-ionizing radiation that comes from power lines, transmitters, or cell phone networks like 5G.
The various parts of PM in the NEI are related as follows. PM10-FIL > PM25-FIL because PM10-FIL includes PM25-FIL PM25-PRI = PM25-FIL + PM-CON This equation only applies at the process level. Because some sources only can report PM2.5 (due to test method differences), this equation does not apply to…
Primary PM2.5 estimates are speciated into the five PM species in the NEI: elemental (black) carbon (EC), organic carbon (OC), nitrate (NO3), sulfate (SO4), and the remainder of PM25-PRI (PMFINE). Diesel engine PM25-PRI and PM10 emissions are also labeled as DIESEL-PM25 and DIESEL-PM10 for mobile source diesel engines. For all…
