Chatham Barrel Yard

         MORE ACTION IS NEEDED TO CLEAN UP THE CHATHAM BARREL YARD                   STATE SUPERFUND SITE

Issue:

The Chatham Barrel Yard is a State Superfund hazardous waste site that has contaminated groundwater, soil, and surface water off-site in southwest Escondido and in Felicita Park.

Summary:

According to official documents, the Chatham Brothers Barrel Yard is the largest site in our region contaminated with toxic chlorinated hydrocarbon pollution.   It was discovered in the 1980’s and designated as a ‘State Superfund’ site.  During the past 30 years, the plumes of contamination have migrated in groundwater over a mile from the site and have polluted local domestic wells, groundwater, and Felicita Creek in violation of water quality standards established in the Basin Plan, and requirements in the MS4 permit.  The contaminated plumes have migrated from the yard and are now under Felicita Park, existing homes, and farmland.  This is a tragic situation that has not been resolved in the over 20 years of remedial action.  Major cleanup efforts have occurred at the Barrel Yard itself, but no cleanup of contaminated groundwater has been done downstream/down gradient of the Chatham site.   Several chemicals from the site are on the Proposition 65 list—a state list of chemicals known to cause cancer or birth defects or other reproductive harm.

Discharges to the surface water of Felicita Creek are continuing unabated in violation of water regulations, adopted remedial objectives, and the Basin Plan.  Local residents have had beneficial and healthful use of their groundwater compromised.  The contamination in the plumes has also been captured by domestic wells which discharge the contamination to land and air without treatment and creating another route of exposure. 

The full Health Risk Assessment was completed in 1996 and many conditions have changed from that time.  New homes are under construction and proposed on areas contaminated by the plumes. The plumes have migrated under more properties and new routes of exposure may occur with the new development plans. The potential for future actions by the county and city that could impact migration of the plume and/or exacerbate erosion through groundwater recharge, discharges, runoff or increased intensities and volumes of flows should be stopped.

And, the plume continues to migrate south toward Lake Hodges, and east and west into developed areas.  As stated in official documents,  “ Temporal changes in constituent concentrations dissolved in groundwater suggest water quality with the off-Yard plume is getting worse in the downgradient direction and will adversely impact groundwater that is not currently impacted. “ 

From June 2004 to March 2010 the plume of TCE has moved 600 feet further downgradient, Tetrachlorethylene (PCE) is 1,200 feet further downgradient, and 1,4 Dioxane is shown in multiple wells that did not have detectable limits before.

The Water Board stated in comments on the 5-Year remedy review in October, 2010, “Therefore, it appears that this remedial objective is not being achieved in the groundwater plume extending south from Hamilton Lane. Should this trend be allowed to continue, the plume may eventually discharge into Lake Hodges, a potable water supply for the City of San Diego.  Such a discharge is unacceptable to this agency.”

ENU Position and Recommendations:

We agree that the current situation is unacceptable.  Although cleanup operations have been underway for 20 years, we are still in this serious condition with discharges on-going.  ENU does not feel that the current remedial strategy is working and  strongly urge that additional measures be taken.

ENU filed its second set of comments on the Five-Year remedial Remedy Review.  Sadly, many of the comments we made in the first review are still true.   

Our August, 2018 letter is here. 

Current Status

We understand there will be a community meeting soon.  We will ask that  additional actions be taken to reduce the contamination from the site. 

Please sign up for ENU's announcements so that you will be kept up-todate.
