This notification by a designated government employee of the California Department of
Toxic Substances Control is made pursuant to the state?s Safe Drinking Water
and Toxic Enforcement Act of 1986 (?Proposition More specifically, this
notification is being made pursuant to California Health and Safety Code section
25180.7, which is part of Proposition 65.

DTSC has obtained information in the course of its of?cial duties pertaining to the
property address specified above, indicating that several chemicals have been detected
in soil gas and groundwater at 790 Greenfield Drive in the City of El Cajon. DTSC has
conducted soil gas, groundwater and indoor air sampling at properties adjacent to this
aerospace manufacturing facility and will be using this information to develop a plan to
further assess surrounding properties and mitigate chemical contamination, as
necessary. Several of the chemicals detected are considered human carcinogens and
may pose unacceptable short and long term risks to human health and the environment.

In September 2016, 29 soil gas samples were collected by an environmental consultant
working for the responsible party. These samples were collected along the adjacent
Magnolia Elementary School property fence line. Trichloroethylene (TCE) is a chemical
which has been found in the groundwater and soil gas at the property address and
surrounding community. Vapors off-gassing from underlying contaminated groundwater
can migrate through the soil and through cracks in the floor and accumulate in the air
inside buildings. The levels of TCE found in soil gas were up to 560 pg/L, which could
potentially exceed indoor air levels that pose an unacceptable risk to human health.

Measures to reduce the risk of breathing in TCE may include increased ventilation,
sealing openings in the floor, treating the indoor air, or recommending temporary
relocation.

If you have any questions, please feel free to contact me at (714) 484-5368 or


I hereby certify that I am a designated employee and that have reported the above
information concerning a discharge or threatened discharge of hazardous waste to the
appropriate officials pursuant to Section 25180.7 of the Health and Safety Code.
