A natural rainforest, Mount Davidson — at 927 feet — is the highest point in San Francisco and one of it’s original “Seven Hills”. Situated on it’s crest is a 103# steel and concrete cross, site of Easter sunrise services. I walked my dogs to the summit of Mount Davidson to enjoy the Stern Grove summer music festival.

Urinary toxicology screen conducted on a Hunters Point hilltop homeowner who reports her asthma is triggered by dust she sees in her environment. She presented during an asthma attack. The chemicals detected in high normal to toxic range correspond to shipyard soils. Cesium, nickel, copper, zinc , lithium, vanadium and thallium are detected in high normal concentrations. Rubidium, manganese, and potassium are detected in potentially toxic levels. The patient does not take potassium or zinc supplements.
EPA cancer and non cancer preliminary remediation goals (PRG’s) for shipyard Parcel soils. Note the presence in Parcel A soils of the same chemicals detected in the urine of the Hunters Point hilltop resident screened during an active asthma episode including copper, manganese, nickel, thallium, vanadium and zinc. Cesium and Rubidium are radionuclides of concern documented by the Historical Radiological Assessment.
The HP Biomonitoring “ROC” cluster detects six radioactive biomarkers concentrated along the shipyards historic main entry at 3rd & Palou east to the radiation contaminated Parcel E shoreline. Each pin corresponds to the detection of a radionuclide in elevated concentrations. Yellow — uranium, green — cesium, black — thallium, red — rubidium, blue — gadolinium, white — strontium. The gamma and alpha emitters Manganese and Vanadium are frequently detected.
The United States Naval Radiological Defense Laboratories operated at HPNS from 1946 to 1969. The main campus occupied the Building 800 series along Crisp Road on the southeast shoreline east to Parcel D.

Hunters Point Community Biomonitoring Program geospatial mapping of radioactive biomarkers detected in residents and workers within the one mile perimeter of the Hunters Point Naval Shipyard. Note distribution of radioactive elements detected on urinary screening along the shipyards historic main entry on 3rd & Palou east toward Crisp Road and the radiation contaminated Parcel E-2 shoreline, industrial landfill — a federal Superfund site and the UCSF compound sited in Building 830.
Biomonitoring California urinary detection frequency of chemicals screened by HP Biomonitoring. Manganese was detected in 19% of 357 people tested. The concentrations detected for up to 75% of screenings are barely detectable.
“From 1955 to 1969, the military consolidated the NRDL campus activities sited along Crisp Road into the multistory windowless Building 815, which was sold to a private party in 1979 and now is leased as a records storage business. At the time, the lab drains emptied into two 10,000 gallon steel holding tanks, then to the city sewer system.”
EPA diagram of potential pathways of exposure to environmental toxins. The findings by the Hunters Point Community Biomonitoring program of multiple chemicals and radionuclides of concern documented to be present in shipyard soils in multiple screenings of nearby residents and workers points to airborne transmission.
Original EPA Pre-Cleanup Hazard Ranking Score for Treasure Island Naval Station-Hunters Point Annex

“A federal Superfund site is, by definition, a property where the EPA used a Hazard Ranking System to calculate a score based on actual or potential release of hazardous substances causing harm to human health. On a scale of 1 to 100, a score of 28.5 or more places a property on the National Priorities List as a Superfund site. The Hunters Point Shipyard has a Hazard Ranking Score of 80 overall and 100 for groundwater migration, corresponding to an 80 to 100% risk the “toxic stew” documented to be present at the shipyard will contact sensitive nearby receptors via airborne, dermal, waterborne and/or ingestible routes. Thus, by legal definition and government classification, the Hunters Point Shipyard is a harmful property and negative health effects in residents and workers on and adjacent to it, under the Precautionary Principle, must be presumed causal.”

Urinary toxicology screening conducted by HP Biomonitoring on a resident who has lived for 20 years within quarter of a mile of the shipyards Parcel E shoreline and served as an elected member of the Restoration Advisory Board. She walks her dog regularly along the southern shoreline and has undergone surgery for breast cancer excision and multiple surgeries for recurrent brain tumors. Her screening yielded alarming findings. Radioactive elements cesium, gadolinium, rubidium and thallium are detected in potentially toxic levels. High normal to toxic levels of copper, manganese, strontium, vanadium, zinc and magnesium are detected.

On March 6, 2019, the City’s Chief Health Officer in charge of population surveillance — Tomas Aragon, MD — sent a letter to Mayor London Breed in which he selectively reviewed data collected by the Greater Bay Area Cancer Registry and determined there was a 31% increase in lung cancer detected in men living in the 94124 zip code during the years 2008–2012. Aragon attributed this startling increase to smoking despite evidence smoking incidences had plummeted and a 2006 DPH report that found smoking to be lower in the 94124 zip code where only 4.0% of Bayview Hunters Point households allowed smoking in the home, compared to 5% in the Western addition and 10% in Ingleside.

Between 2006 and 2007 over 2 million tons of sepentinite rock was graded from the Hunters Point hilltop for an ambitious mixed use development project that created Lennar Corporations neighborhood on Parcel A-1. Serpentine is a source of asbestos and heavy metals including manganese, vanadium, chromium,copper, zinc, iron, cobalt and nickel. These heavy metals along with radioactive elements are being detected with 100% detection in residents and workers within a one mile radius of the Hunters Point Naval Shipyard.
Greater than 20 tons of particulate matter emissions are generated in the 94124 zipcode each year according to the EPA.
Urinary screening conducted by HP Biomonitoring on Building 830 long time worker detects high normal to toxic levels of cesium, gallium, platinum, rubidium, thallium, manganese, vanadium, zinc, calcium and potassium. These findings correspond with chemicals and radionuclides documented by the Parcel E-2 ROD to be present in Parcel E-2 soils.
The Declaration of the Parcel E-2 Record of Decision documents soil, sediment and groundwater contaminants that have been detected in 15 UCSF workers occupying Building 830 on the Parcel E-2 shoreline within feet of the Industrial Landfill
UCSF Radiation Report 2018 includes photo documentation of soil contamination of Building 830. In a privileged email dated 05/11/2020, Robert Greger- Senior Health Physicist California Department of Public Health states, “I wanted to let you know that CDPH-RHB has not performed any radiation testing of Buildings 830/831.” In 2018 Dr. James Cook of UCSF EH&S performed a limited scoping survey.
A gamma scan conducted by the California Department of Public Health detected 110 above background gamma anomalies and the finding of a radium emitting deck marker in this shipyard neighborhood.

City’s Toxic Shipyard Development is Killing Us!

2018 District 10 Supervisor Candidate Gloria Berry sent a decade in the U.S. Navy climbing antennas for ship maintenance. In 2012 she was diagnosed with a rare chronic blood disorder. Berry sponsored a Resolution to the California Democratic Party on behalf of “her generation of residents battling health disparities and for the children in the Baview who have yet to be born. “

“It was adopted that the San Francisco DCCC urges the City of San Francisco, the State of California, the US Navy and the Federal Government to halt all construction and further resolves that reparations be paid to the residents of Bayview Hunters Point in the form of healthcare to include toxic testing and personal injury compensation in order to begin repairing the damage caused by years of exposure to radioactive waste and environmental injustice.”

The Hunters Point Shipyard Redevelopment Project is the largest redevelopment initiative undertaken in San Francisco since the 1906 earthquake. It is the brainchild of former Mayor Willie Brown who remains a principal driving its development and “The Elephant in the Room at the Hunters Point Shipyard.”

Heavy Metals and Epigenetic Alterations in Brain Tumors

Urinary screening conducted on 30 year old Hunters Point resident since childhood diagnosed with a brainstem glioma and underwent radiation treatment two years ago. Brainstem gliomas and induced by exposure to heavy metals. The urinary screening detects numerous heavy metals in high normal to toxic range including aluminum, antimony, cadmium, gadolinium, nickel, chromium, copper, iron, manganese, molybdenum and vanadium. Deficiencies in essential nutrient elements are also noted including selenium, zinc, calcium, strontium, manganese, potassium and sulfur.
