Data Validation - A well-defined procedure for assessing whether or not a set of environmental data have met acceptability criteria defined in the Data Quality_ objective process. This procedure may follow existing guidelines, for example those define by EPA (Guidelines for data validation; EPA New England data validation guidelines) or they can be defined by the user as part of the DQO process.
