In-­‐Situ  Thermal  Remediation    Short  Course  

 

 

 

This  short-­‐course  will  provide  regulators,  consultants,  and  field  applicators  with  an  understanding   of   the   three   types   of   in-­‐situ   thermal   remediation   available  commercially  including:  thermal  conductive  heating,  electrothermal  desorption  and  steam.   Additional   benefits   from   heat   generation   will   be   discussed   regarding  increasing  the  rates  of  naturally  occurring  processes  including  hydrolysis,  reductive  dehalogenation   and   aerobic   or   anaerobic   biodegradation.   Some   important   design  factors  for  their  applicability  and  operation  will  be  discussed  to  identify  when  in  situ  thermal   is   appropriate  as  well   as  when   it   is  not.   The   case   studies   reviewed   in   the  course  will  identify  the  thermal  technology  employed  and  the  results  at  various  site  conditions.    

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

In-­‐situ   thermal   remediation   (ISTR)   offers   rapid   soil   and   groundwater   remediation   that   can  reduce   the   time   to   remediate   volatile   organic   compounds   (VOCs)   and   semi-­‐volatile   organic  

compounds  (SVOCs)  from  years  to  months.  From  multiple  years  of  applying  this  technology  on  many   different   contaminants   and   site   lithologies,   ISTR   now   provides   site   owners  with   both  performance  and  financial  certainty  in  their  site-­‐closure  process.  The  ability  of  the  technology  

to   remediate   soil   and   groundwater   impacted   by   chlorinated   solvents   and   petroleum  hydrocarbons,   regardless   of   sediment   type   and   fractured   bedrock,   proves   to   be   extremely  beneficial   over   conventional   in-­‐situ   technologies   that   are   dependent   on   adjective   flow.   The  

technology  is  very  tolerant  of  subsurface  heterogeneities  and  performs  as  well  (if  not  better)  in   low-­‐permeability   silts   and   clay   as   it   does   in   higher-­‐permeability   sands   and   gravels.   By  utilizing   simple   engineered   controls,   ISTR   is   routinely   implemented   around   and   under  

buildings  and  public  access  areas  without  significantly  upsetting  normal  business  operations.  ISTR  may   also   be   combined   with   other   treatment   technologies,   such   as   bioremediation   or  chemical  oxidation,  to  optimize  and  enhance  its  performance.
