Tap water in Puerto Rico is generally treated and regulated to meet safety standards, and many sources indicate it is safe to drink. However, public opinion and some reports note distrust and occasional concerns about testing and contaminants in certain areas or during infrastructure issues. If you’re visiting or newly settled, consider these practical checks:

• Where you are matters: urban centers with newer infrastructure (like San Juan) tend to have stricter monitoring, but some rural or older systems may have more variability.
• Annual reports: utilities publish water quality reports; these can tell you about contaminants detected and any advisories for your area.
• Taste and odor: if water tastes or smells off, you may prefer filtered or bottled water temporarily.
• Boil-water advice: during advisories or after events (like Hurricanes), authorities may recommend boiling tap water for safety.
• Personal precautions: if you have concerns about pipes or local advisories, using a certified home water filter or drinking bottled water for a short period is reasonable.
