Griffin-Schruers, incorporated


Griffin-Schruers, incorporated has extensive experience in Data Validation, Data Assessment and Laboratory Auditing. 

Data Validation:  the task of solely evaluating data completeness, accuracy, basic usability (i.e., is a data point rejected or valid) and performance from both a laboratory and sample matrix standpoint.  Codes referred to as qualifiers are added to sample results that indicate some sort of deficiency.

Data Assessment:  the task of translating the results of Data Validation into useful and usable information for engineers, end-users, etc.   This task takes a deeper look at the meaning of qualifiers and applies reality checks on data qualifers within the scope of a project's wider bounds.

The following is a partial list of parameters and programs we can assess and validate:

  • Volatile Organics (CLP, 8240, 8260, etc.)
