(National Pollutant Discharge Elimination System)

NPDES is a federal permit program used to regulate wastewater discharges to Illinois streams and lakes. They provide facility owners with a discharge-specific set of conditions under which discharges may occur and establish monitoring and reporting requirements.

Environmental Consulting Group, Inc. can conduct testing of your discharge. Typically, the work involves the following steps:

  • Visiting the site to collect water samples using clean disposable polyethylene bailers and laboratory-provided glassware appropriate for the specified analysis.
  • Submitting the samples to an accredited laboratory for analysis. The results are compared to Title 35 Ill. Adm. Code (IAC), Section 304, Subpart A: General Effluent Standards (GES). The GES are the basis for the NPDES discharge standards.
  • Completing a report that summarizes ECG’s field activities and the analytical results for all sampled materials.
