Accident Investigation
PD Hours: 1 Viewing Format(s): Fee: $30.00 Purchase / Take Exam


This operator education course will examine accident investigation, identify the components of a prevention program, and describe how to implement the program. Treatment plant safety reflects literally thousands of hazards. Preparation for all hazards, regardless of their chance of occurring in one’s particular circumstances, is an almost impossible task. However, implementation of an accident investigation program can effectively focus a facility on safety issues..

Educational Objectives:
  1. Understand why accidents should be investigated.
  2. Know who should investigate accidents.
  3. Understand accident investigation follow-up.
  4. Be able to apply accident investigation concepts.

Biochemical Oxygen Demand and Carbonaceous Biochemical Oxygen Demand
PD Hours: 1 Viewing Format(s): PDF Fee: $30.00 Purchase / Take Exam


This operator education course explains in a step by step method how to perform the Biochemical Oxygen Demand (BOD) and Carbonaceous Biochemical Oxygen Demand (Carb BOD) analytical tests, including quality assurance and control measures. This method can be used to report BOD and Carb BOD results to Ohio EPA as required in wastewater treatment plant National Pollutant Discharge Elimination System (NPDES) Permits. All needed equipment, chemicals, and glassware is listed. Data and sample calculations are presented to provide templates for the operator to use when performing this test.

Educational Objectives:
  1. Understand what BOD and Carb BOD analytical tests measure and how to perform those tests.
  2. Have a clear understanding of the appropriate quality assurance checks used for this analytical test.
  3. Understand how to prepare materials for these tests.

Bloodborne Pathogens
PD Hours: 1 Viewing Format(s): PDF Fee: $30.00 Purchase / Take Exam


This operator education course will explain the dangers associated with bloodborne pathogens. In addition to bloodborne pathogens, other potentially infectious materials may present a risk of harm in the wastewater workplace. In this contact hour course, both blood and other infectious materials will be referred to as “PIM” (potentially infectious materials).

Educational Objectives:
  1. Understand the nature of bloodborne pathogens.
  2. Learn about types of potentially infectious material.
  3. Introduce students to wastewater infectious diseases.
  4. Understand means of transmission.

Drinking Water Precipitation Softening
Not Rated
PD Hours: 1 Viewing Format(s): PDF Fee: $30.00 Purchase / Take Exam


This course defines hardness as it relates to drinking water and discusses some of the associated problems. The precipitation softening process for drinking water treatment is also discussed with an emphasis on the chemistry of softening.

Educational Objectives:
  1. Upon completion of this course, the operator should understand the cause of drinking water hardness, the impacts and the precipitation process for softening.

Introduction to a Quality Assurance/ Quality Control Plan
Not Rated
PD Hours: 1 Viewing Format(s): PDF Fee: $30.00 Purchase / Take Exam


This operator education course will enable the operator/analyst to understand and develop a QA/QC plan for a Water and Wastewater Treatment Plant laboratory. Even though the Water and Wastewater Treatment Plant have different functions, the importance of the laboratory data accuracy remains the same.

Educational Objectives:
  1. Understand how to produce legally defensible analytical records of test results.
  2. Understand equipment calibration and preventative maintenance procedures.
  3. Understand the process for validating methods used to analyze a sample.

Microscopic Examination of Activated Sludge
PD Hours: 1 Viewing Format(s): PDF Fee: $30.00 Purchase / Take Exam


This operator education course explains differences between basic types of microorganisms present in activated sludge, their metabolism and correct distribution to achieve optimum wastewater treatment. In addition, the Settling test and food to microorganism (f/m) ratio is explained and sample calculations are provided to aid the operator in optimizing treatment of the wastewater prior to discharge.

Educational Objectives:
  1. Understand how to use a microscope to view microorganisms present in activated sludge.
  2. Understand microorganisms’ differences, metabolism and correct distribution to achieve optimum wastewater treatment.
  3. Understand the importance of the microorganism groups as they relate to determining the food to microorganism (f/m) ratio and settling characteristic.

Sampling and Field Analysis
PD Hours: 1 Viewing Format(s): PDF Fee: $30.00 Purchase / Take Exam


This course is designed to introduce the operator/analyst to sampling and field analysis methodology at water and wastewater treatment plants. At the heart of any effective analysis is the necessity for quality assurance and quality control. Not all water and wastewater analysis is done in the laboratory. It is often a single individual who must have the knowledge and capabilities of both an operator and an analyst. Inasmuch, he/she must be well-versed in the necessity of quality assurance and quality control in the collection and analysis of water or wastewater, not only in a laboratory setting, but also in the field.

Educational Objectives:
  1. Explain the importance of quality assurance and quality control in the field.
  2. Discuss the duties of the operator relevant to sampling and analysis.
  3. Describe proper steps for field collection of samples for water or wastewater analysis.
  4. Describe field analysis methods for water and wastewater systems.

Stainless Steel Feedwater and Condenser Tubing – Expectations, Results, and Choices
PD Hours: 2 Viewing Format(s): PDF Fee: $59.00 Purchase / Take Exam


Stainless steel has become the often preferred choice for replacement of old, or fabrication of new, condenser and feedwater heater tubes. The objective of this course is to provide the student with the fundamentals on how tubes are fabricated so that the student can make an informed decision on selection of stainless steel tubing for condenser or feedwater heater applications.

Educational Objectives:
  1. Understand the differences between seamless and welded condenser tubing.
  2. Be familiar with common stainless feedwater heater alloys.
  3. Understand the pros and cons of a variety of non-destructive testing approaches.
  4. Understand the advantages and disadvantages of weld bead cold working and heat treatment options.

Taste and Odor Control in Drinking Water
PD Hours: 1 Viewing Format(s): PDF Fee: $30.00 Purchase / Take Exam


For many years, surface water operators have recognized the ability of algae, phytoplankton, and bacterial organisms to produce tastes, odors, and clogging of sand filters. These organisms affect pH, alkalinity, corrosion, toxicity, color, turbidity in water, and the operations of water systems. This course will help the water plant operator to better understand problems associated with microorganisms in drinking water, how to identify and analyze taste and odor problems, and how to correct the problems associated with taste and odor problems in drinking water.

Educational Objectives:
  1. Identify the causes of taste and odor in municipal water supplies.
  2. Describe the characteristics of taste and odor problems.
  3. Discuss methods to control taste and odor in drinking water.
