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…

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…

Is there a Pennsylvania registry that tracks non-cancer diseases or immunological disorders?
PADOH and the U.S. Department of Health and Human Services do not have a registry for multiple sclerosis (MS), MS-related diseases or immunologic disorders. Despite extensive research on the mechanisms of MS development and progress, the exact mechanism is not known and there are no definitive studies to show causation…

What is included in the emissions “Tiers”?
The Tiers are assigned by a Source Classification Code (SCC), which has the most detail about the emissions processes that generate the emissions. The full list of SCCs, their associated Tiers, and the SCC descriptions is available online at https://ofmpub.epa.gov/sccwebservices/sccsearch/ .

How do we know our drinking water has not been affected over the past 40+ years when the landfill was operating and after it closed since there were no regulations governing its operation or closure?
The Norwood community is serviced by a public drinking water source. The public water supply must meet federal and state Safe Drinking Water Act Standards. Public water systems are required to share annual reports that describe what, if anything, is found in the water supply.

Why is it difficult to establish a link between cancers or other illnesses and environmental exposures?
The complex nature of cancer makes it inherently challenging to identify, interpret, and address cancer clusters. Cancer is a term describing different diseases that share a similar characteristic: uncontrollable cell growth and division. As a group, cancers are very common. Cancers are the second leading cause of death in the…

What are the units of NEI emissions data?
NEI emissions values represent total annual emissions for the inventory reporting year. Criteria air pollutants and precursors (CAPs) are reported in short tons per year , and hazardous air pollutants (HAPs) are reported in lbs per year .

How do we know that we have not been exposed to contamination from the Landfill for the past 40+ years?
EPA works closely with its partner, the Agency for Toxic Substances and Disease Registry (ATSDR) in evaluating potential health exposures from waste sources. ATSDR has the ability to look at the cancer registry data to evaluate potential past exposures, while EPA’s role is to evaluate current and future exposure. ATSDR…

Can Norwood residents be exposed to contamination if we grow and eat our own vegetables from gardens in our yards?
To date, contamination has not been found on residential properties that would pose a risk. In addition, the concentrations of the contaminants found at the Norwood Site are often found in urban communities. Studies show that exposure to contaminants via vegetable gardens is negligible. With the exception of some root…

What does "NEC" stand for in the emissions sectors?
NEC means “not elsewhere classified” and includes SCCs that are not assigned to any of the other specific industrial process sectors. If you look at the SCC code table available at the SCC web site and filter on the Sector name that includes “NEC”, you can see the type of…
