Bathing in the Ganges is recommended in all Vedic śāstras, and one who takes to this path will certainly be completely freed from all sinful reactions.

SB 9.9.14, Translation and Purport

Because mother Ganges emanates from the lotus toe of the Supreme Personality of Godhead, Anantadeva, she is able to liberate one from material bondage. Therefore whatever is described herewith about her is not at all wonderful.

It has actually been seen that anyone who regularly worships mother Ganges simply by bathing in her water keeps very good health and gradually becomes a devotee of the Lord. This is the effect of bathing in the water of the Ganges. Bathing in the Ganges is recommended in all Vedic śāstras, and one who takes to this path will certainly be completely freed from all sinful reactions. The practical example of this is that the sons of Mahārāja Sagara went to the heavenly planets when water from the Ganges merely touched the ashes of their burnt bodies.
