ABSTRACT  Soil   gas   surveys   are   used   extensively   as   a   screening   tool   for   delineaEng   contaminant  plumes   in   the   subsurface.     For   20   years,   local   regulatory   agencies   accepted   and   oOen  required   soil   gas   surveys   on   sites   to   “pin   point”   contaminant   hot   spots   for   further  invesEgaEon  and  delineaEon.    In  2003  the  DTSC  provided  guidelines  for  performing  soil  gas  surveys   and   they   are   currently   working   on   a   revised   guideline.     More   recently,   soil   gas  surveys   are   used   by   regulators   to   evaluate  whether   a   site   is   adequately   remediated   and  provides  no  vapor  intrusion  risk  to  site  occupants.    In  2005,  the  DTSC  provided  an  addiEonal  guideline  on  the  evaluaEon  and  miEgaEon  of  vapor  intrusion  to  indoor  air.    But  are  all  soil  gas   surveys   the   same?     Are   different   surveys   necessary   for   different   site   condiEons,   or  different  project  goals?    What  condiEons  affect  the  results  of  surveys?    What  types  of  lab  analyses  will  provide  the  most  accurate  results  for  the  project  goals?  

This   lecture  will  discuss  the  theory  behind  soil  gas  migraEon,  the  many  factors  that  affect  migraEon   and   the   variability   of   chemical   consEtuent   concentraEons   in   the   subsurface.    Proper   construcEon  and  placement  of   soil   gas  probes  will  be  discussed  as  well   as  proper  sampling   techniques.     The   significance   and   variability   of   purge   volume   tesEng   will   be  presented  as  well  as  the  significance  of  purge  volume  tesEng  on  concentraEons  of  specific  chemical   consEtuents.     Examples   of   soil   gas   surveys   from   contaminated   sites   will   be  presented  for  plume  delineaEon  and  vapor  intrusion  to  indoor  air.    Soil  gas  monitoring,  or  the   repeated   measurement   of   soil   gas   from   the   same   vapor   probes   over   Eme,   will   be  discussed   as   well   as   the   affect   of   temperature   and   soil   moisture   on   results.     Lastly,  anEcipated  future  revisions  to  the  current  DTSC  soil  gas  guidelines  will  be  discussed  as  well  as  the  use  of  soil  gas  surveys  for  the  evaluaEon  of  the  soil  and  groundwater  remediaEon.

CHAIR  MESSAGE  I   would   like   to   begin   this  month’s  message  with   congratulaEons   to   the   new   Board   of  Officers   for   the  upcoming  2010-­‐2011  year  starEng  in  October.    ElecEons  were  held  during  our  previous  July  meeEng  and  I  am  pleased   to  announce  Frank   Jordan  as  your  new  Chapter  Chair,    Debbie  Kunath  who  will   remain  as  Vice  Chair,  Kerry  Cato  as  your  new  Secretary,  and  Dave  Gaddie  who  will  also  remain  as  Treasurer.    We  will  have   a   smooth   transiEon   to   the   new   board   as   this   group   of   dedicated   professionals   has   a   strong  background   in  serving  our   local  AEG  chapter  as  well  as  other  professional  organizaEons  over  the  years.    Please  keep  in  mind  that  we  are  always  looking  for  volunteers  in  other  capaciEes  as  well  which  includes  support  for  the  annual  fieldtrip,  short  course,  memberships,  newslener  or  even  as  a  guest  speaker.    If  you  would  like  to  get  involved  in  our  AEG  Chapter  in  any  capacity  please  let  us  know.    Email  contacts  are  listed  in   the  newslener  or  you  can  speak  with  any  one  of   the  board  members  at  our  monthly  meeEngs.     It’s  never  too  late  to  Get  Involved!  

Thanks   again   to   everyone  who  made   it   to   our   last   chapter  meeEng   in   July   at   the   Spaghep  Factory   in  Rancho  Cucamonga.    Due  to   the  posiEve   feedback  we  received   from  many  members  we  will  make   it  a  point  to  try  to  get  back  to  this  venue  in  the  near  future!    We  had  a  large  and  lively  turnout  for  our  guest  speaker  Jerry  Treiman  with  the  California  Geological  Survey  (CGS).  Jerry  had  some  fascinaEng  up  to  date  data  on  numerous  fault  segments  within  the  Imperial  Valley  that  had  triggered  slip  due  to  the  April  4,  7.2  MW  El  Mayor-­‐Cucapah  earthquake   south  of  Mexicali.     Field  mapping,   as  well   as   cross   evaluaEon  with  newer  aerial  mapping  programs  such  as  Interferrograms,  not  only  confirmed  triggered  slip  on  numerous  known   faults,   but   also   resulted   in   the   discovery   of   previously   unidenEfied   fault   segments.     The  informaEon  from  the  CGS’s  mapping  and  evaluaEon  will  be  published  at  some  point  in  the  future  and  we  will  keep  you  posted  when  that  informaEon  becomes  available.      

Our   upcoming   meeEng   and   chapter   presentaEon   will   be   held   once   again   at   the   Sizzler   restaurant   in  Temecula  and  we  are  pleased  to  present  Mr.  Anthony  Severini,  president  and  owner  of  Environmental  Support   Technologies,   as   our   guest   speaker.     Mr.   Severini’s   presentaEon   will   concentrate   on   the  environmental  side  of  our  industry  specifically  with  regards  to  soil  gas  surveys.    This  talk  will  highlight  the  technical  side  of  conducEng  and  interpreEng  soil  gas  surveys  as  well  as  looking  at  the  regulatory  agencies  and   how   this   affects   the   environmental   industry.   This  will   be   a   great  meeEng   for   any   students   and/or  those   professional   geologists   whose   primary   work   is   in   the   environmental   field   who   don’t   normally  anend   our   engineering   geology   presentaEons.     Spread   the   word   to   anyone   you   might   know   in   the  environmental  field.      

Also,   please   keep   in   mind   there   will   be   no   chapter   meeEng   in   September   due   to   the   naLonal   AEG  meeLng   in  Charleston,  South  Carolina.     There  will  not  be  another  meeEng   in   the  Temecula  area  unEl  November   (October   will   be   at   a   “northern”   venue).     If   you   would   like   informaEon   on   anending   next  months   naEonal   meeEng   you   can   email   me   at   djohnston@petra-­‐inc.com.   If   you’ve   never   been   to  Charleston  I  highly  recommend  it!  

 Please  join  us  at  our  August  18  meeLng  in  Temecula;  the  social  will  start  at  5:00pm.      

         Regards,  

Douglass  Johnston,    Chair,  AEG  Inland  Empire  Chapter
