- A. Clean Water Act
- B. Virginia Graeme Baker Pool and Spa Safety Act

The Virginia Graeme Baker Pool and Spa Safety Act (2007) is the federal law establishing drain safety requirements for public pools.
An operator finds a thick, persistent layer of foam on a spa's surface, particularly when the jets are running. The sanitizer and pH levels are within their ideal ranges. This foaming is most commonly caused by:
- A. Excessively high calcium hardness levels.

- C. The use of a polyquat-based algaecide.
- D. Low total alkalinity below 50 ppm.
Answer: B. A buildup of bather-introduced contaminants like soaps, lotions, and oils.
Foaming in spas is typically caused by a buildup of surfactants, which are compounds introduced by bathers through body oils, lotions, cosmetics, and detergents left on swimwear. The aeration from the jets agitates these substances, creating stable bubbles that accumulate as foam.

- A. Compare with another operator's reading
