Sample Class

You may search the entire database for the following different classes of samples and results:

•  TCR Samples – Total Coliform sample results (whose Analyte Code is 3100, 3013, or 3014) that meet your selection criteria.

•  TCR Samples Detection Only – Total Coliform sample results (whose Analyte Code is 3100, 3013, or 3014) where Coliform is identified as present and that meet your selection criteria.

• TCR Summaries – Total Coliform sample summaries (whose Analyte Code is 3100) that meet your selection criteria.

• Lead and Copper Summaries – 90th percentile Lead and Copper sample summaries (whose Analyte Code is PB90 or CU90) that meet your selection criteria

• Summarized Field Sample Results – Summarized Field Sample Results (MDPB summaries) that meet your selection criteria.  (These results are collected to support the federal Interim Enhanced Surface Water Treatment Rule and Disinfectant ByProduct Rule.)

•  Non-TCR Samples All – Chemical, radionuclide, microbiological, and water quality parameter samples (whose Sample Results’ Analyte Code is not 3100, 3013, or 3014) that meet your selection criteria.

• Non-TCR Samples by Analyte – All non-TCR analytes referenced by sample results (excluding those where Analyte Code is 3100, 3013, or 3014) that meet your selection criteria.  If the analyte does not appear on this list, no sample results for that analyte and your criteria exist in the database.

•  Non-TCR Samples Detection Only – Chemical, radionuclide, microbiological, and water quality parameter samples (whose Analyte Code is not 3100, 3013, or 3014) where the Result Concentration is greater than 0 and that meet your selection criteria.
