Fact of the Week #4: Banned Pesticides and School Playgrounds?

Proposed Conejo Creek development and School Site

 

DDE and Toxaphene Pesticides  “Drift” and Proximity to Playgrounds

The Draft Environmental Impact Review (DEIR) found legacy pesticides “exceeding screening levels” on the school site for the proposed Conejo Creek Development (DEIR P. 4.8-12). DDE  is a form of DDT which is persistent in the environment and at least as toxic as DDT.   Toxaphene is also persistent in the environment and can be carried long distances in the air.  They both belong to the so-called “dirty dozen” list of very toxic substances. In 1990 both were banned for all uses in the United States.

Both DDE and Toxaphene combine strongly with soil particles.  As a result these compounds concentrate in sediments and can be transported from application sites as dust.  With the extensive dredging of the bypass channel (2 miles long, 300 foot wide, 10 – 20 foot deep), and 2 lakes (40 acres) and all the grading required to “lift” this area out of the floodplain, these airborne legacy pesticides could create the threat of pesticide drift exposure to adjacent Camarillo High School and nearby Rancho Rosal School.

In addition to the risk of toxic drift during construction there is the fact that this elementary or middle school site would be within one mile of the already existing Pancho Road industrial/manufacturing area.  Table 4.8-1 on page 4.8-7 (in the Environmental Impact Analysis section of the DEIR) lists all the hazardous material designations that are at these existing businesses.  The Conejo Creek Properties industrial development would surround and expand this existing area by 100+ acres…adding over 1 million square feet of industrial activity to this site.
