CLEANUP TIMELINE

Listing-date and cleanup-phase enrichment from EPA's per-site SEMS profile is queued for a follow-up ingest pass. Until then, this section will populate from EPA's published timeline data.

Contaminants of concern · per EPA SEMS

What Contaminants Are In Pearl Harbor Naval Complex

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)Soil5
AntimonyHealth riskInhaled antimony trioxide is an IARC Group 2B possible carcinogen; respiratory and cardiovascular effects from long-term exposure. EPA MCL 6 µg/L. (IARC, EPA)Soil3
Benzo[A]PyreneHealth riskPAH; IARC Group 1 carcinogen; the prototypical PAH used to benchmark PAH-mixture cancer risk. EPA MCL 0.2 µg/L. (IARC, EPA)Soil3
LeadHealth riskNeurotoxin. Even low childhood exposure impairs cognitive development; chronic adult exposure damages kidneys and the cardiovascular system. (EPA, ATSDR)Soil3
Polychlorinated Biphenyls (Pcbs)Health riskPCBs. IARC Group 1 carcinogen; immune, reproductive, and neurological effects; bioaccumulate in fish and breast milk. Banned in 1979; persist as legacy contamination. (IARC, EPA)Soil3
Alpha-ChlordaneHealth riskIARC Group 2B possible carcinogen; neurotoxin; banned for most uses in 1988 but residues persist. (IARC, EPA)Soil2
Aroclor 1260Health riskPCBs. IARC Group 1 carcinogen; immune, reproductive, and neurological effects; bioaccumulate in fish and breast milk. Banned in 1979; persist as legacy contamination. (IARC, EPA)Soil2
Benzo(B)FluorantheneSoil2
CadmiumSoil2
ChromiumHealth riskHexavalent chromium (Cr-VI) is an IARC Group 1 carcinogen via inhalation, causing lung cancer; trivalent chromium is far less toxic. (IARC, EPA)Soil2
CopperHealth riskInhaled copper fumes cause metal-fume fever; chronic ingestion above EPA's 1.3 mg/L action level damages the liver. (EPA)Soil2
Dibenzo(A,H)AnthraceneSoil2
DieldrinHealth riskIARC Group 3 (inadequate evidence) but EPA classifies as 'probable human carcinogen'; neurotoxin and persistent organic pollutant. (EPA, ATSDR)Soil2
Gamma-ChlordaneHealth riskIARC Group 2B possible carcinogen; neurotoxin; banned for most uses in 1988 but residues persist. (IARC, EPA)Soil2
MercuryHealth riskNeurotoxin. Methylmercury bioaccumulates up the food chain and damages the developing nervous system. (EPA, ATSDR)Soil2
P,P'-DdeHealth riskIARC Group 2A probable carcinogen; persistent bioaccumulator; banned in the US in 1972 but residues persist in soil and sediment. (IARC, EPA)Soil2
P,P'-DdtHealth riskIARC Group 2A probable carcinogen; persistent bioaccumulator; banned in the US in 1972 but residues persist in soil and sediment. (IARC, EPA)Soil2
ZincHealth riskGenerally low acute toxicity. Chronic high-dose exposure disrupts copper absorption and immune function. (ATSDR)Soil2
2-(2,4-Dichlorophenoxy)Propanoic AcidSoil1
2-Butanone (Methyl Ethyl Ketone)Soil1
2-MethylnaphthaleneSoil1
3,6-Dichloro-2-Methoxybenzoic AcidSoil1
4-Methyl-2-Pentanone (Methyl Isobutyl Ketone)Soil1
9H-FluoreneSoil1
AcetoneHealth riskLow chronic toxicity; high acute exposure causes CNS depression and respiratory irritation. (EPA, NIOSH)Soil1
AntimonyHealth riskInhaled antimony trioxide is an IARC Group 2B possible carcinogen; respiratory and cardiovascular effects from long-term exposure. EPA MCL 6 µg/L. (IARC, EPA)Sediment1
AsbestosHealth riskIARC Group 1 carcinogen. Causes mesothelioma, lung cancer, and asbestosis. (IARC, EPA)Soil1
BenzeneHealth riskIARC Group 1 carcinogen. Long-term inhalation causes leukemia and bone-marrow disorders. (IARC, EPA)Groundwater1
Benzo[A]AnthraceneHealth riskPAH; IARC Group 2B possible carcinogen; common combustion byproduct and creosote constituent. (IARC)Soil1

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.
