How much alum to use for muddy water to clear for drinking?

To clarify muddy water for drinking, you can use about 1 teaspoon of alum (potassium aluminum sulfate) per gallon of water. Stir the alum into the water thoroughly and allow it to sit undisturbed for several hours, which will help the suspended particles settle to the bottom. Afterward, carefully siphon or pour the clear water from the top, ensuring you don't disturb the sediment. Always ensure that the water is boiled or treated further for safety before consumption.
