There is more to surface-water sampling than simply submerging the empty sample container into a river or lake! The importance of implementing correct sampling strategies and methods for surface-water sampling is often overlooked in environmental site investigation and characterization programs. This series of two modules introduces you to some of the important and unique terminology associated with sampling surface-water systems. It also reviews why it is important to understand how aquatic systems behave, how they are hydraulically connected to ground-water systems and why it is important to incorporate surface-water sampling into ground-water sampling programs at many sites. The first module discusses a variety of objectives of surface-water sampling projects, discusses in depth the many details that need to be considered when designing an effective surface-water sampling event, provides guidance on determining when to collect discrete vs. composite samples, and explains why taking vertical profiles with multi-parameter sondes can be an important part of determining where samples should be collected. Field videos in this module explain how to plan and prepare for a sampling event. The second module describes in detail the operational characteristics and applications of a variety of surface-water sampling devices, from pond samplers or “dippers” to depth-discrete sampling devices like Kemmerer samplers and Van Dorn bottles. Field videos in this module explain the use of a wide variety of sampling devices for collecting representative samples from surface-water bodies under a variety of field conditions. While you may opt to take just one of these modules, it is strongly recommended that you take both modules in the prescribed order if you want comprehensive coverage of the subject.
