What chemical is used to adjust the pH of water at California Pajarosa?

Explanation:
Adjusting water pH means adding an acid strong enough to bring the pH down to the desired level. Nitric acid is used at California Pajarosa because it is a strong, fast-acting acid that lowers pH efficiently without introducing chloride ions, which can cause corrosion and taste issues, or adding large amounts of sulfate. Acetic acid is weaker and would be less effective for quick pH control, while hydrochloric and sulfuric acids would introduce chloride or sulfate ions that aren’t as desirable for this purpose.
