2、ber in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice describes the procedure and equipment fortaking surface samples of water or other liquids using a dipper.A pond sampler or dippe
3、r with extension handle allows theoperator to sample streams,ponds,waste pits,and lagoons asfar as 15 ft from the bank or other secure footing.The dipperis useful in filling a sample bottle without contaminating theoutside of the bottle.1.2 This standard does not purport to address all of thesafety
