Corrosion Control

Effective Corrosion Control Starts Here

To help water utilities comply with recent and potential regulations intended to better protect communities from lead exposure in drinking water, AWWA and the Association of State Drinking Water Administrators (ASDWA) have launched a new corrosion control eLearning program.

NEW! New corrosion control certificate program supports lead reduction planning

ABOUT THE PROGRAM

Three courses now available! This online education program will guide you from the chemistry of corrosion all the way through performing a corrosion control evaluation. Courses range in length from 2-4 hours, and are designed to be self-paced and completed in order. The final course will be released soon. 

With the announcements of upcoming Lead & Copper Rule Revisions, water utilities need targeted and credible resources to help craft the best lead reduction plan for their specific community, including strategies for corrosion control. This training guides participants through a decision process that experience has shown to be successful in developing corrosion control strategies.

Program Course Descriptions

Course 1: Corrosion Control Theory and Treatment Options | EL285

A comprehensive review

EL285 - Corrosion Control Theory and Treatment Options

Course Length: 2 Hours  |  $180 Member/$225 Nonmember

Course #1 is aimed at demystifying corrosion control and provides a guide to the basics of internal corrosion control.  The Corrosion Control Theory and Treatment Options course covers topics such as: 

  • Corrosion behaviors of common metals
  • Physical and water quality factors influencing metal release
  • Corrosion control treatment options and how they may be applied to minimize the release of lead and copper


Prerequisite/Background: Please note that the course Corrosion Control Theory and Treatment Options (EL285) assumes a basic knowledge of water chemistry.  If needed, we encourage you to pair EL285 with AWWA’s EL228 – Basic Math & Chemistry eLearning course for a water chemistry refresher. 
 

Module 1: Basic Concepts for Understanding Corrosion in Drinking Water Systems 
Module 2: Corrosion of Metals Commonly Present in Water Systems
Module 3: Predicting the Risk for Corrosion and Metal Release
Module 4: Corrosion Control Treatment Methods


EL285 Learning Objectives:

  • Name materials which are sources of lead or copper release
  • Explain electrochemical processes that are the source of corrosion
  • Interpret Eh/pH (Pourbaix) and solubility diagrams
  • Recall physical and water quality factors influencing metal release
  • Apply corrosion principles to recognize how metal is released from materials commonly used in distribution systems and premise plumbing
  • Identify Corrosion Control Treatment (CCT) options which minimize corrosivity of treated water toward lead, copper, iron, galvanized iron, brass, and leaded solder
  • Explain correct usage of corrosion indices
  • Outline major aspects of a corrosion control program

Course 2: Assessing Need for A Corrosion Control Evaluation | EL286

EL286 - Assessing Need for A Corrosion Control Evaluation

Course Length: 4 Hours | $230 Member/$275 Nonmember

This course, the second in the AWWA-ASDWA Corrosion Control Certificate Program, will help the learner explore aspects of corrosion control theory that can be used to select and test Corrosion Control Treatment (CCT) that best minimizes the release of lead and copper from distribution system and premise plumbing materials.
 
Module 1: Importance of Applying Corrosion Control Treatment
Module 2: Data To Collect To Support Decisions
Module 3: How To Analyze Data To Support CCT Decisions
Module 4: When Is It Appropriate To Initiate Or Revisit CCT?

Learning Objectives:

  • Explain the context for applying Corrosion Control Treatment (CCT)
  • Identify what data are needed to support CCT decisions and where data gaps exist
  • Describe key considerations and techniques for analyzing data
  • Determine when it is appropriate to initiate or revisit CCT
  • Recognize source or treatment changes that are likely to warrant a CCT evaluation
  • Identify possible water quality impacts as they relate to CCT that could results due to a change in source or treatment
  • Decide which corrosion control studies are appropriate for evaluating CCT
 

Course 3: Performing A Corrosion Control Evaluation | EL287

EL287 - Performing A Corrosion Control Evaluation

Course Length: 3 Hours | $185 Member/$230 Nonmember

This course consists of the following four modules: 

Module 1: Methods and Tools for Evaluating Corrosion Control Treatment

Module 2: Demonstration & Field Studies

Module 3: Selecting and Implementing CCT

Module 4: Monitoring and Evaluating CCT Effectiveness

 

Learning Objectives:

Explain methods and tools for evaluating CCT
Describe differences and considerations in demonstration testing methods
Identify additional criteria when selecting CCT
Define steps for implementing CCT
Recall tools and considerations for evaluating CCT effectiveness

 

Course 4: Using A Corrosion Control Evaluation to Help Meet the Lead & Copper Rule Revisions (LCRR)

EL - Using A Corrosion Control Evaluation to Help Meet the Lead and Copper Rule Revisions (LCRR) 

Coming in 2023
