Residents’ vigilance on Marinwood toxic cleanup pays off

Marinwood residents sent a message, loud and clear, to the state board responsible for the cleanup of a toxic spill at a neighborhood shopping center.
The spill is from dry-cleaning solvents used at one of the center’s shops. Today, that shop is one of the many closed stores in the center, as the focus has been on cleaning up the tainted soil and redeveloping the property.
Until recently, the site was seen as a potential location for building affordable housing; but the spill, local opposition and the economy stood in the way of plans. County supervisors, at one time, had agreed to reduce potential housing development on the St. Vincent’s School for Boys and Silveira ranches because of local support for building it on part of the mostly vacant Marinwood Shopping Center property.
Backers of the plan saw the redevelopment as a way to support their local grocery store, and some had visions of expanding some of the community services district’s recreation programs to the site.
But in recent years, after finding the spread of an underground plume of tetrachoroethylene, a compound that had been commonplace in dry cleaning stores, the focus has been on cleaning up the property.
Neighbors focused on the clean-up have found that their definition of clean is different than that of the state Regional Water Quality Control Board, whose staff had recently been prepared to declare the site ready for development.
Some 450 Marinwood residents signed a petition and dozens of emails were sent to the water board urging it not to sign off on the cleanup.
“I asked the board, ‘would you like this your neighborhood?’” said resident Bill Nicholas, who requested that the board do more to address soil vapor found onsite and require additional testing of neighboring Caltrans land.  READ THE FULL ARTICLE HERE

How toxic soil vapor will be removed if Casa Marinwood residents speak up.



Toxic soil gas needs ACTIVE clean upat Marinwood Plaza to protect neighboring Casa Marinwood from the toxic soil vapor that the owners want to leave in the ground to dissipate gradually.

Active soil vapor extraction should commence immediately.

Photographs of the Toxic waste site known as the Eastern Hot Spot behind Prosperity Cleaners in Marinwood Plaza


A series of groundwater testing sites first established in 2007 revealed high level of contamination.
The wells are located a few feet from the chainlink fence. On the other side is Caltrans Right of Way (Miller Creek Ave. Southbound on ramp.)

The door on the right is the back door to the room where the dry cleaning machinery was kept.  A toxic hot spot was found underneath the machinery and excavated to 15 feet in 2017.  Toxic waste was discovered at a depth greater than 35' ( below the water table).  Treatment was administered in 2017 which dropped toxic levels but still it is above residential standards. The toxic soil vapor remains a threat to Casa Marinwood and workers inside Marinwood Plaza.

The second door to Prosperity Cleaners has been boarded up  and debris remains after work in 2017.

A view from Caltrans property to that shows the toxic hotspot in the foreground and you can make out the back door to Prosperity Cleaners in the background. 

When the workers in the Prosperity Cleaners plant cleaned machinery, they would dump the buckets of liquid containing toxic PCE into the grassy area next to the chain link fence.  Although the toxic soil has been treated on the Marinwood Plaza side of the fence, there have been NO soil testing and treatment on the Caltrans property.  The discharger claims that the toxic soil has been fully treated but this is preposterous as the toxic waste would tend to run downslope through the chainlink fence and into the ground on both sides.  Unless both sides of the fence are tested and treated  there is NO ASSURANCE that the toxic waste has been fully treated. It may continue to generate toxic soil vapor and pollute the groundwater for DECADES.

Toxic waste is very harmful to pregnant women, children and the immune compromised.  It is vital that ENVIRONMENTAL JUSTICE is served to protect the health of the most vulnerable.  Marinwood Plaza has been the site of two affordable housing proposals.  It almost got built last time when there was an attempt to cover up the toxic waste issue.  Fortunately, citizens uncovered the data and are now advocating on the behalf of the community, Casa Marinwood, St Vincents and Silviera Ranch.

Five Minutes to understand the Basics of the Marinwood Plaza Toxic Waste Problem







Only a few drops of PCE can poison an entire pool.
The original "spill" reported in July 2013 was reported as "only a few pounds" by Geologica and the spill less than a few hundred square feet.  It is now estimated to be 1/2 mile to the East and we still not have full defined the plume. We estimate hundreds of pounds may have spilled since the business began in 1965.
Geologica is recommending only to remove a 10' x 10 x 15' deep section of toxic soil. The known plume is well over 500,000 square feet and they will only remove 100 square feet?  RIDICULOUS!


This is the size of "a few pounds" of PCE. It is about 1 pint or .47 liters.

The Geologica Remedial Action Plan is incomplete and relies on inaccurate and incomplete data for its recommendations.  Worse still, it does not have a start date which means that they are asking the board to permanently delay remediation until after a buyer is found. Meanwhile NO ACTIVE REMEDIATION has occurred since 2011 while TOXIC WASTE has spread.  This is not acceptable.



Tetrachloroethylene (Perchloroethylene)

127-18-4

Hazard Summary-Created in April 1992; Revised in December 2012
Tetrachloroethylene is widely used for dry-cleaning fabrics and metal degreasing operations. Effects resulting from acute (short term) high-level inhalation exposure of humans to tetrachloroethylene include irritation of the upper respiratory tract and eyes, kidney dysfunction, and neurological effects such as reversible mood and behavioral changes, impairment of coordination, dizziness, headache, sleepiness, and unconsciousness.  The primary effects from chronic (long term) inhalation exposure are neurological, including impaired cognitive and motor neurobehavioral performance.  Tetrachloroethylene exposure may also cause adverse effects in the kidney, liver, immune system and hematologic system, and on development and reproduction. Studies of people exposed in the workplace have found associations with several types of cancer including bladder cancer, non-Hodgkin lymphoma, multiple myeloma.  EPA has classified tetrachloroethylene as likely to be carcinogenic to humans.
