Regulatory context

Your Permit Specifies the Test. We Run It.

NPDES effluent limits, industrial pretreatment programs, and local discharge ordinances all mandate metals analysis. Exceeding permit limits triggers violations, fines, and permit suspension. Accurate effluent characterization is your first line of defense.

Exceeding permit limits triggers violations, fines, and permit suspension. Accurate effluent characterization is your first line of defense against enforcement action.
NPDES Compliance
  • Clean Water Act Section 402 — all point source discharges require NPDES permits
  • Permit specifies effluent limits for metals — typically daily max and monthly average
  • Monitoring frequency defined in permit — monthly to quarterly for most metals
Industrial Pretreatment
  • 40 CFR Part 403 — indirect dischargers must meet local limits before discharge to POTW
  • Categorical pretreatment standards for electroplating, metal finishing, food processing, and circuit board manufacturing
  • Local POTW may have stricter limits — IRIS results directly comparable to permit limits
Baseline & Closure
  • Pre-discharge baseline characterization documents natural background
  • Site closure or permit termination requires exit sampling to document final discharge quality
  • Litigation support — chain-of-custody reports accepted in administrative and civil proceedings

IRIS NJ NELAP certification means results are accepted for all NJ NPDES permit reporting.

Decision guide

Which Service Matches Your Situation?

Match your permit type and regulatory obligation to the right service.

NPDES permit holder — direct discharge to surface water Permit specifies metals, frequency, and method — EPA 200.5/200.7 results submitted directly to NJ DEP on discharge monitoring reports.
NPDES Compliance Monitoring
Industrial facility discharging to municipal sewer (POTW) 40 CFR Part 403 and local POTW limits apply — categorical or local limits must be met before discharge to the sewer system.
Industrial Pretreatment
New facility permit application or permit renewal — need baseline data Pre-permit baseline documents existing effluent quality; supports application and limit negotiation with the permitting authority.
Effluent Characterization
Site closure, litigation support, or regulatory response Chain-of-custody reports and NJ NELAP certification ensure defensible documentation for administrative and civil proceedings.
Effluent Characterization
Construction stormwater — metals in dewatering discharge Construction general permits require stormwater metals monitoring — EPA 200.5 results satisfy monitoring report requirements.
