This course has been developed using the ABC Water Treatment, Water Distribution, Wastewater Treatment, and Wastewater Collection Need-to-Know Criteria. The ABC Need-to-Know Criteria describe the core competencies covered on the ABC standardized exams used by the Iowa DNR Operator Certification Program for their Water Treatment, Water Distribution, and Wastewater Treatment certification exams and by the Iowa Water Environment Association Certification Program for their Wastewater Collection certification exams.

The ABC Need-to-Know Criteria covered by this course are:

  1. Evaluate Characteristics of Source Water
  2. Monitor, Evaluate, and Adjust Treatment Processes
  3. System Information/Components
  4. Laboratory Analyses
  5. Operate, Maintain, and Evaluate Equipment and Lift Stations
  6. Perform Security, Safety, and Administrative Procedures

Competencies
  1. Utilize the ABC Formula/Conversion Table to prepare for state certification exams and for treatment process operations.
    1. Calculate areas, volumes, capacities, and velocity.
    2. Calculate detention time, chemical dose, and various overflow rates.
    3. Recognize the correct equation to solve a given word problem.
    4. Determine treatment process loadings and chemical dosages.
  2. Employ the correct formula for specific math problems.
    1. Determine whether to multiply or divide to obtain the correct answer to a given problem.
    2. Solve algebraic equations having variables in members, parentheses, and fractions.
  3. Apply calculated data to determine process efficiency and make process changes.
    1. Demonstrate how to determine process efficiency.
    2. Utilize laboratory and process data to optimize process performance.
    3. Detect poor or substandard process performance using math.
  4. Practice the correct conversion factor for specific math problems.
    1. Determine whether to multiply or divide to obtain the correct answer to a given problem.
    2. Demonstrate that the units of expression are correct for the conversion.
