Essential Water Analyses Series
Full Series (All 4 Sessions)


Course Description:

This four-course series is an overview of analyses commonly performed in a wastewater laboratory. Each session will focus on the “why” we analyze for a particular parameter as well as the “how.” Sessions are designed to be interactive with poll questions to monitor understanding and step by step demonstrations of procedures and calculations.

Series Topics
Session 1: Sampling, Safety, Quality Control, pH, fecal coliform, chlorine residual
Session 2: Residues – TSS, TS, TVS, TVSS, TDS
Session 3: BOD, COD, TOC
Session 4: Nutrients – ammonia, TKN, phosphorus, nitrate, nitrite

Expected Learning Outcomes:

Completion of the course will provide attendees with a basic understanding of sampling, reference methods, quality control, and safety.

For each analysis discussed, attendees will know:

  • Wastewater program requirements
  • What the analysis measures and how operators may use analysis results
  • How to perform the method
  • Associated quality control
  • Tips for optimal performance
  • Calculations associated with the method
  • Common issues with method performance and troubleshooting tips

Intended Audience:

This course is designed for Accreditation Bodies, Assessors, Internal Auditors, Quality Managers, Analysts, and Laboratory Managers.
