, Aerojet's director of environmental restoration at the facility, repeatedly has assured residents that they are not in danger.The activities of Aerojet [ have ] not affected surface water and ground water and certainly not your drinking supply, he
publicly stated last year, days after DTSC's accounting of the company's sludge slopping into streams leading to the Santa Ana River.
Despite that finding, neither DTSC nor DHS has asked the Orange County Water District (OCWD) to test for Aerojet contaminants ; district officials in Fountain Valley said they knew nothing about the Chino Hills site and were having trouble locating it on a map..
An OCWD official said the district doesn't test for the explosive chemicals HMX and RDX–indeed, HMX isn't in the OCWD data base and the federal Environmental Protection Agency is still developing a test for RDX.While the official said perchlorate has been found in trace amounts, he
pointed out that the district tests water at the base of the Prado Dam in Riverside County and at the Santa Ana River at the Imperial Highway juncture in Anaheim Hills ; both sites are miles upstream from where state officials figure Aerojet toxins are entering the river from Carbon Canyon Creek.
Since Aerojet received the DTSC's approval to begin dismantling the facility in 1995, some 364 tons of soil tainted with perchlorate have already been hauled away, according to geoscientist Joseph Bahde, who works for McLaren / Hart, an Irvine-based environmental contractor brought in by Aerojet.
