Missing Values in ICR Tables

NO DATA

The value is missing for many possible reasons:

The sample may not have been required under the ICR for this water treatment plant's source water characteristics or the plant's treatment type.
Quality control requirements for the ICR sampling and analysis may not have been met, thus causing the result to be rejected by EPA, the water system, or the laboratory.
Examples of quality control requirements that would cause data rejection include failure of analytical quality control standards required during sample analysis, or sample holding times being exceeded.
The sample may have been lost during shipment to the laboratory, thus no results could be reported.
The sample may not have been taken.
