How can I tell if the water in my tap is safe to drink?

The best way to tell if the water in your tap is safe to drink is to check for any visible signs of contamination. Look for discoloration, cloudiness, or a foul odor. You should also test the pH level of the water and compare it with the recommended range (6.5-8.5). If the pH level is outside of this range, you may want to consider boiling the water before drinking it.
