TIER 1
Educational Level

Acceptable Data Uses

  • Community Education
  • Municipal Engagement
  • Targeting Additional Advanced Monitoring

Data Quality Requirements

  • Study design documenting monitoring site information, methods, and timeframe

TIER 2
Targeting Level

Acceptable Data Uses

  • All Tier 1 Uses, plus:
  • Report Cards
  • BMP Effectiveness Assessment
  • BMP/Restoration Implementation Targeting
  • Targeting Additional Advanced Monitoring
  • NJDEP Regional Comprehensive Assessment

Data Quality Requirements

  • QAPP approved at Tier 2 by affected NJDEP Bureaus on file with NJ Watershed Watch Network
  • Use of standard field, lab, and analysis methods

TIER 3
Advanced Level

Acceptable Data Uses

  • All Tier 1 and 2 Uses
  • Regulatory Assessments of Water Quality Standards Attainment

Data Quality Requirements

  • QAPP approved at Tier 3 by NJDEP, EPA, or USGS
  • Water Chemistry: Use of NJDEP Certified Lab or OQA-certified “analyze-immediately” parameters for handheld and continuous meters
  • Macroinvertebrates: Use of NJDEP-approved sampling design

Tier 3 Macroinvertebrate Sampling Designs

TIER 3.1
Good

  • Americorps NJWAP sampling methods
  • Streamside organism identification to Order/Level
  • Volunteers must pass a 50-organism test with 90% success

TIER 3.2
Better

  • Sample preservation in the field
  • Volunteer organism identification to family level
  • Volunteers must pass a 50-organism test with 90% success

TIER 3.3
Best

  • Sample preservation in the field
  • Laboratory identification to genus level
