Additional Services

Working with subcontract laboratories

In addition to the analyses performed by our laboratory, ETS works with several subcontract laboratories.  This enables all parameters found in your NPDES permit to be accommodated.  For many clients, this provides a single point of contact for all of their analytical requirements.

Turn-Around Time

    • ETS is in contact with all subcontract laboratories to provide the specified turnaround time.

Data Review

    • Upon receipt of subcontract reports, ETS reviews the analytical data for proper hold times, detection limits and quality control limits.
    • All subcontract data, including the cover page, report, quality control data and subcontract COC are incorporated into the ETS report.

Quality Control Information

    • NC DENR inspections, performance evaluations and certifications of subcontract laboratories are reviewed by ETS and maintained on file.
