What state or federal agencies are responsible for evaluating records from the PADOH cancer registry? Are all types of cancers considered in this evaluation [including rare and/or environmentally associated cancers]?
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…

What is a site assessment and what is the difference between a site assessment and a site investigation?
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…

What questions was EPA trying to find answers to during its first round of sampling at the Norwood Landfill site?
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…

What does it mean when EPA finds contamination that “exceeds screening levels?”
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 EPA finds any contamination associated with the Norwood Landfill site that “exceeds” what is considered safe, will EPA clean up that contamination - even if the Agency cannot find any “pathways” for that contamination to reach humans or sensitive environments?
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…

How do you know you are not missing some areas that might be contaminated?
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.

Why hasn’t the Norwood Landfill Site been identified as a Superfund Site? Two nearby landfills, Folcroft and Clearview, which were established and in use at the same time as Norwood Landfill and Dump have both been designated as Superfund sites.
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…

How do the different parts of particulate matter (PM) fit together?
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…

How does PM2.5 relate to PM species such as EC, OC, SO4, NO3, PMFINE, and DIESEL-PM25?
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…
