CRE Receives Comment Offering Different Perspective on Data Quality
While CRE agrees that pinpoint accuracy of scientific values in every situation may be unwarranted, Data Quality in the context of current congressional legislation focuses on federal agencies' information use and dissemination. The onus to correct inaccuracies would be on the agencies and would only be triggered where an interested party brings a petition, thereby presumably limiting instances of Data Quality challenge for mere academic benefit. However, CRE values this important perspective which should surely be kept in mind.

There has been a trend toward increasing quality assurance requirements for environmental samples. These can include multiple sampling personnel, rinsing equipment with pure water, etc. All with the intent of assuring that the laboratory result is absolutely correct.
However, it should be recognized that regulated facilities are not necessarily interested in obtaining the absolute value. The only purpose of most samples is to determine if the result is greater or less than a regulatory limit. If a sample is contaminated but still demonstrates compliance, it should be sufficient. Even if it is not suitable for other regulatory purposes.
