INTERNATIONAL WASTEWATER LABORATORY ANALYST CERTIFICATION
EXAMINATION 2026| CERTIFIED WASTEWATER LABORATORY ANALYST
(CWLA) EXAMINATION
FINAL ASSESSMENT IN WASTEWATER ANALYSIS, SAMPLING, LABORATORY
INSTRUMENTATION, QUALITY ASSURANCE/QUALITY CONTROL (QA/QC), AND
ENVIRONMENTAL REGULATIONS – 2025/2026
Within the federal government, the following branch generates laws:
(a) Congress
(b) Office of the President
(c) Supreme Court
(d) Library of Congress
A
Explanation
Just a little reminder from your high school government class. The federal government is divided
into 3 branches: executive - the President; legislative - Congress (the Senate and the House of
Representatives); and judicial - the Supreme Court. The legislative branch generates laws so the
correct answer is Congress. The Library of Congress is not correct, but those into speed reading
may have just seen the word "Congress" and selected this answer.
The law that governs wastewater analysis is:
(a) Safe Drinking Water Act

, (b) Resource Conservation and Recovery Act
(c) Clean Water Act
(d) Federal Water Pollution Control Act
C
Explanation
The correct answer is the Clean Water Act. The Safe Drinking Water Act covers drinking water,
while the Resource Conservation and Recovery Act covers hazardous waste disposal. The
Federal Water Pollution Control Act is a precursor to the Clean Water Act and has been
superseded.
Within the federal agency that develops wastewater regulations, the Office that is responsible
for the wastewater programs is:
(a) Office of Enforcement
(b) Office of Research and Development
(c) Office of Solid Waste and Emergency Response
(d) Office of Water
D
Explanation
The Environmental Protection Agency (EPA) develops wastewater regulations and within the
EPA the Office of Water is responsible for wastewater programs under the Clean Water Act. The
Office of Solid Waste and Emergency Response regulates hazardous waste disposal, not
wastewater. The Office of Research and Development may at times be involved in the
development of wastewater methods, but it does not administer the wastewater programs.
