(a) Congress fv


(b) Office of the President

t is divided into 3 branches: executive - the President; legislative -
fv fv fv fv fv fv fv fv fv fv fv


Congress (the Senate and the House of Representatives); and judicial -

The law that governs wastewater analysis is:
fv fv fv fv fv fv




(a) Safe Drinking Water Act
fv fv fv fv


(b) Resource Conservation and Recovery Act
fv fv fv fv fv


(c) Clean Water Act
fv fv fv


(d) Federal Water Pollution Control Act - ANSWERS-C

Explanation
The correct answer is the Clean Water Act. The Safe Drinking Water Act covers drink

ing water, while the Resource Conservation and Recovery Act covers hazardous was
fv fv fv fv fv fv fv fv fv fv fv


te disposal. The Federal Water Pollution Control Act is a precursor to the Clean Wate

Explanation
The Clean Water Act specifically authorizes the EPA Administrator to identify testing
