ACIL's voice was successful in convincing the EPA to revise their guidance for sample holding times.  When holding time is specified in days, the window for analyzing samples for EPA's SW-846 Program is now the end-of-day of the expiration day, rather than at the time of day the sample was initially collected.  The SW-846 and Office of Water requirements are now consistent.
