The objective of sampling is to collect a portion of
material small enough in volume to be transported conveniently and yet large
enough for analytical purposes while still accurately representing the material
being sampled. But,
statistically, greater than 66% of all analytical errors contained in
analytical results come from the sampling process. Therefore, when you are
assessing the uncertainty of the final result; you must remember the
contribution from sampling errors. These errors cannot be evaluated or
controlled using standards or reference materials.
This course has been prepared to assist employees in the general awareness of water and wastewater regulatory sampling and in dealing with often-complex procedures and requirements for safely handling hazardous and toxic materials. The scope of the material is quite large, requiring a major effort to bring it under control. Employee health and safety, as well as that of the public, depend upon careful application of regulations and safe working procedures.
Individuals who are responsible for water/wastewater sampling and the health and safety of workers at hazardous waste sites must obtain and comply with the most recent state and local regulations relevant to these sites and are urged to consult with OSHA, EPA and other appropriate state and local agencies.
The course will cover the required procedures and work rules relating to water and wastewater sampling.
