Contaminants of concern · per EPA SEMS

What's In This Site

Each row pairs a contaminant with the medium it was found in (the exposure pathway). Hover any named contaminant for an agency-cited health-risk summary. Cited count = number of SEMS decision records (RODs and related) that name the pair.

ContaminantPathwayCited
ArsenicHealth riskIARC Group 1 carcinogen via inhalation and ingestion. EPA MCL 10 µg/L; chronic exposure causes skin, lung, bladder cancer and cardiovascular disease. (IARC, EPA, ATSDR)Groundwater2
BenzeneHealth riskIARC Group 1 carcinogen. Long-term inhalation causes leukemia and bone-marrow disorders. (IARC, EPA)Groundwater2
Chloroethene (Vinyl Chloride)Health riskIARC Group 1 carcinogen — angiosarcoma of the liver. Final TCE/PCE biodegradation product; commonly found in groundwater plumes. EPA MCL 2 µg/L. (IARC, EPA)Groundwater2
LeadHealth riskNeurotoxin. Even low childhood exposure impairs cognitive development; chronic adult exposure damages kidneys and the cardiovascular system. (EPA, ATSDR)Groundwater2
N,N-Diphenylnitrous AmideGroundwater2
NickelHealth riskNickel compounds are IARC Group 1 carcinogens; inhalation exposure raises lung and nasal cancer risk. (IARC)Groundwater2
AcetoneHealth riskLow chronic toxicity; high acute exposure causes CNS depression and respiratory irritation. (EPA, NIOSH)Groundwater1
Alpha-HexachlorocyclohexaneHealth riskLindane. IARC Group 1 carcinogen (added 2015); banned for agricultural use in the US in 2007. (IARC, EPA)Groundwater1

BariumHealth riskSoluble barium compounds are toxic if ingested, affecting the heart, kidneys, and nervous system. Insoluble forms (e.g. barium sulfate) are far less toxic. (EPA)Groundwater1

Chloroethene (Vinyl Chloride)Health riskIARC Group 1 carcinogen — angiosarcoma of the liver. Final TCE/PCE biodegradation product; commonly found in groundwater plumes. EPA MCL 2 µg/L. (IARC, EPA)Landfill Gas1
ChromiumHealth riskHexavalent chromium (Cr-VI) is an IARC Group 1 carcinogen via inhalation, causing lung cancer; trivalent chromium is far less toxic. (IARC, EPA)Groundwater1
ChromiumHealth riskHexavalent chromium (Cr-VI) is an IARC Group 1 carcinogen via inhalation, causing lung cancer; trivalent chromium is far less toxic. (IARC, EPA)Leachate1
CopperHealth riskInhaled copper fumes cause metal-fume fever; chronic ingestion above EPA's 1.3 mg/L action level damages the liver. (EPA)Leachate1
CyanideHealth riskAcutely lethal at high doses by blocking cellular respiration; chronic low-dose exposure damages the thyroid and nervous system. (EPA, ATSDR)Leachate1
Dichloromethane (Methylene Chloride)Health riskIARC Group 2A probable carcinogen; central-nervous-system depressant; banned for most consumer paint-stripper uses. (IARC, EPA)Landfill Gas1
DieldrinHealth riskIARC Group 3 (inadequate evidence) but EPA classifies as 'probable human carcinogen'; neurotoxin and persistent organic pollutant. (EPA, ATSDR)Groundwater1
Gamma-Hexachlorocyclohexane (Lindane)Health riskLindane. IARC Group 1 carcinogen (added 2015); banned for agricultural use in the US in 2007. (IARC, EPA)Groundwater1
HeptachlorHealth riskIARC Group 2B possible carcinogen; metabolizes to heptachlor epoxide. (IARC, EPA)Groundwater1
IronGroundwater1
ManganeseHealth riskExcess inhalation can cause manganism, a Parkinson-like neurological disorder. (ATSDR)Leachate1
PhenolHealth riskCorrosive on contact; absorbed through skin; high exposure damages kidneys, liver, and the central nervous system. (NIOSH)Leachate1
SilverHealth riskChronic exposure can cause argyria — irreversible blue-grey skin discoloration. Generally low systemic toxicity. (ATSDR)Groundwater1

Drinking-water linkage · SDWIS

No Groundwater PWSes Serving Communities Within 3 Miles

No SDWIS public water systems drawing groundwater (or mixed sources) serve a community whose centroid sits within 3 miles of this site. Empty results are not a guarantee of non-impact — distance is computed to served-place centroids, and SDWIS does not expose individual wellhead locations.

Methodology: served-city centroid (TIGER 2020) is used as the PWS coordinate. Source-water classification from SDWIS primary_source_code; only groundwater and mixed-source systems are queried. Click any system above for its full SDWIS profile.

What this is not. We report EPA's published Superfund record — site listing, status, and contaminants of concern as named in EPA's decision documents. We do not perform site visits, independent air or water sampling, or current-state health-risk assessment. NPL listing reflects EPA's Hazard Ranking Score at a point in time; it does not by itself describe present-day exposure.
