摘要:Appropriate field sampling and the proper handling of water samples to the point of their arrival in laboratories for analysis is a prerequisite for any successful groundwater assessment. Yet, in many cases, simple mistakes are made due to a lack of knowledge of fundamental field sampling practices. This new video responds to this need by clearly demonstrating ‘best practices’ in collecting and handling samples in the field needed for utilizing isotopic techniques to support groundwater assessment activities. Field staff are often not involved in either planning of sampling campaigns or in assessing the data acquired. The wide distribution and use of this video should lead to improved abilities of field staff to conduct sampling appropriately and lead to better results in groundwater assessment activities.
