<br /> Subject: Report#040701-L,concerning the measured levels of ambient air and surface contamina-
<br /> tion that remain in the 3 bedroom,3 bath,single story home located at:
<br /> 10285 N. Hildreth Lane
<br /> Stockton, CA 95212
<br /> This on-site'evaluation was completed at 10:45 AM,on�tednesday,�•�tLys ��"'�.w Wit.`•
<br /> The;above tefercnced home was raided by Nazcotics Officers who Had been advised at the time of tiicit.
<br /> tiYSltsctfo6iirg3s a'°Srrug Lab,"3itosfpiobably for the manafacnlre
<br /> of methamphetamines or "Crank." Because of tho nature and the inherent dangers associated with
<br /> clandestine drug manufacturing,and because a number of toxic chemicals are routinely used during
<br /> these types of operations, concern remained about the possibility that hazardous and/or toxic residues
<br /> might still exist at this location. In completing my evaluation of this structure,however,I observed that
<br /> the San Joaquin Sheriff's documentation that had been left in this home indicated the presence of
<br /> marijuana ONLY, thus I am not certain why it was necessary for me to validate that this structure was
<br /> cleat of the toxic residues commonly associated with"Drug Labs."
<br /> In any case,on the morning of Wednesday,7 July 2004,I monitored the ambient air in every part of
<br /> this home. In completing this monitoring task,I used two analytical instrusnerlts that had been calibra-
<br /> tion checked on the afternoon of Tuesday,6 July 2004. These two instruments are capable of detecting
<br /> and quantifying low concentration levels(0.01 -0.10 ppm)of all the volatile solvents commonly used
<br /> in the manufacture of illicit drugs. In order,I monitored for:(1) acetone,(2)dichloromethane, (3)iso.-
<br /> propanol,
<br /> so-propanol,(4)methanol, (5) toluene,(6)chloroform,and finally,(7) 1,1,1-trichloroethane. I was able to
<br /> determine that every area within this house was clear of hazardous or toxic levels of the vapors of each
<br /> of these seven chemicals.
<br /> In addition, I checked all of the most likely work surfaces and chemicals disposal locations in this.
<br /> home. In completing these checks I looked for signs.of acidic or alkaline residues. None of the areas I
<br /> checked showed any evidence of these types of residues,or of any other type of toxic contamination. It
<br /> imy judgment that none of the interior portions of this living unit pose any type of health lid to
<br /> _ j1 J
<br /> to vfd'it73 6e iequtred Yk be in any part of it.
<br /> Shouldyou have any questions on any of the conclusions of this report,please do not hesitate to con-
<br /> tact me. Thank you very much for petirlitting me to be of service to you in this matter.
