Perjure Away Pollution in Runkle Canyon?

Perjure Away Pollution in Runkle Canyon? has discovered evidence that Boeing-supplied documents contain false data as it pertains to Runkle Canyon, which calls into question whether additional sampling and testing in Runkle Canyon may be necessary to fully and accurately investigate the nature of the contamination and its source.

Meltdown Dustup

Meltdown Dustup

The worst meltdown in U.S. history happened 30 miles northwest of Los Angeles from July 13-26, 1959. A reactor spewed hundreds of times more radiation than Three Mile Island did in 1979. The effects of this covered-up meltdown still reverberate throughout Southern California today.

Environmental investigations can take a lot of time and are arduous to research, write and produce. We call it “the slog.” There are times that are especially trying like getting Version 2 of up and running properly. It’s just at times like these that kind words remind Denise Anne and I why we do what we do. And now that we are in our eleventh year reporting on the lab, it also reminded us never to take any complements too seriously.

Sodium Reactor Experiment Meltdown

Sodium Reactor Experiment Meltdown

The 50th anniversary of the worst nuclear reactor disaster in U.S. history happened just outside of Los Angeles July 13-26, 1959 and still resonates today.

In the course of our Ahmanson Ranch investigation, has assembled hundreds of documents totally thousands of pages. This treasure trove of information includes the entire hard copy and computer files of two former newspaper editors who were on the scene before we were (but who had done nothing significant with the information).
In addition to […]

White Blight Chromium – March 26 and June 10, 2008

On March 26, 2008, Radiation Rangers “Fearless Frank” Serafine and “The Good Reverend John” Southwick visited Runkle Canyon and found a strange sight – thousands of white rocks and what appeared to be some kind of white evaporate or precipitate covering large swaths of land. Southwick called by cell phone from the canyon. […]

Runkle Canyon 11-08-08

During the debate over whether Runkle Canyon’s surface water is a drinking water source for Simi Valley, a number of folks have insisted that it isn’t, including members of the Department of Toxic Substances Control. Indeed, Runkle Canyon drains into the Arroyo Simi which replenishes the aquifer under Simi Valley which is pumped out and […]

Sodium Reactor Experiment 6 – Demolition

JIM GARNER WORKED IN THE LATE 70S for a company; called Brownyard Steel Fabrication, which was doing contract work for Rocketdyne at the Santa Susana lab, we wrote in “Hot Zone,” a 1998 Los Angeles magazine cover story. He recalls standing in a steel vault 60 feet underground, tearing out old ironwork and putting new […]


KB Home promises mass grading of Runkle Canyon
By Michael Collins
Ventura County Reporter – April 16, 2009
Leave it to Simi Valley’s Radiation Rangers to uncover more than just contamination in Runkle Canyon, where KB Home hopes to build 465 homes in the shadow of radioactive Rocketdyne. The citizens group has discovered that the developer has dug […]


City planners make a slick zone change for easy building on toxic lands

LA Weekly – March 5, 2009
West Hills resident Bonnie Klea is vivacious and no-nonsense. She won a battle over a rare bladder cancer diagnosed in 1995, and has long suspected the toxins that taint a big piece of land near her […]

SSFL Area IV – Sodium Reactor Experiment

The Sodium Reactor Experiment, or SRE, was the first nuclear reactor in this country to supply commercially-available electricity. It powered the lights for the-then tiny town of Moorpark in Ventura County, California, population 1,200. The reactor is best known for suffering the worst meltdown in American history, releasing hundreds of times more radiation in the […]

SSFL Area IV – SNAP wrote about the SNAP reactor’s two partial meltdowns in a September 23, 2004 Ventura County Reporter article entitled “In Hot Water – More good news about contamination from your friends at Rocketdyne,” where it was noted:
“At the meeting last week, Rocketdyne divulged that two new wells had high levels of tritium registering approximately 82,000 […]

“The Radiation Measurements Facility (Building 4029) was used between 1959 and 1974 for the storage and use of radioactive sources to calibrate radiation detection instruments for the SRE and other reactor tests,” according to the DOE. “In March, 1964, a radium source was dropped in a storage thimble; the plastic […]

(Click thumbnail to view entire photograph)
“During reactor test operations, it was often necessary to examine reactor fuel assemblies and other test specimens to determine how they were performing,” according to the Department of Energy. “This involved handling and examining highly radioactive items. These operations were done remotely in the heavily shielded Hot Laboratory (Building 4020) […]

SSFL Area II – Gallery C

In Area II of SSFL is the Delta site, first constructed in 1957 for Thor engine testing and later modified for the Lance J-2 programs, including altitude testing. The area has also been used for the loading of propellant for Peacekeeper Stage IV. The DELTA 1 and 2 test stands conducted 105 and 462 rocket […]

The Santa Susana Field Laboratory’s Area IV’s extensive radiological contamination is the result of partial meltdowns, accidents, spills along with burning and dumping. Six out of ten experimental reactors suffered major accidents including the 1959 partial meltdown of the Sodium Reactor Experiment, or SRE, which released hundreds of times more of certain […]


Area III of the Santa Susana Field Laboratory (SSFL) encompasses a number of facilities, most of which are astronomically polluted. The drainage from Area III makes its way down Bell Canyon and into the Los Angeles River to the east. These facilities include the ECL Pond which was used for treatment and storage and is […]

SSFL Area II – Gallery B

SSFL Area II includes the rocket test stands at the Coca Area, seen here. “Three test stands were initially constructed at the Coca area in 1956 to support the development of the Navaho and Atlas engines,” according to Rocketdyne Archives. “In 1963, two of the original stands were demolished and replaced by two large engine […]

SSFL Area II – Gallery A

SSFL Area II includes the rocket test stands at the Alpha Area and Bravo Area, seen below. Operational with three test stands beginning in 1955, Alpha supported the first manned orbital flight of Atlas-Mercury in 1962. Both Alpha and Bravo areas are heavily polluted as are some of the surrounding structures including the Hazardous Waste […]

SSFL Area I – Gallery B

SSFL’s Area I consists of 671 acres owned by Rocketdyne and 42 acres owned by NASA (formerly owned by U.S. Air Force) in the northeast portion of the site. It includes the former Area I Thermal Treatment Facility and three rocket engine test areas, the Bowl, Canyon, and Advanced Propulsion Test Facility (APTF) areas. The […]

SSFL Area I – Gallery A

The 2,850-acre Santa Susana Field Laboratory sits high in the hills between the Simi and San Fernando valleys in eastern Ventura County, California. Our ongoing investigation of Rocketdyne, as it is commonly called, began in 1998. Area I is the site of years of rocket tests, laser experimentation and a host of activities that have […]

RFI Groupings – Investigation Areas

Resource Conservation Recovery Act Facility Investigations, or RFI groupings, are areas of the Santa Susana Field Lab that are characterized for contamination. Once this work is completed, the lead agency for the cleanup of Rocketdyne, California EPA’s Department of Toxic Substances Control, solicits public comment before final approval of each RFI’s work plan.
At least that […]

Aerojet Chino Hills Clean Up

What a difference a $46 million cleanup makes! Aerojet Chino Hills would already be covered in upscale homes without our investigation that uncovered unexploded munitions, depleted uranium and toxic fuel oxidizer perchlorate problems at this former military industrial plant. The Aerojet Chino Hills facility is 29 miles (45 km) east-southeast of downtown Los Angeles […]
