Valmiki Ramayana states that Ganga is considered sacred because it came by touching Anga (Head) of Lord Shiva:
तत्र ऋषि गण गन्धर्वा वसुधा तल वासिनः १-४३-२६
भव अंग पतितम् तोयम् पवित्रम् इति पस्पृशुः |
And asserting that the water as holy, because it descended touching the body of Shiva, viz., the head of Shiva, the assemblages of sages, gandharva-s, and those that are residents on the plane of earth have sipped that water at that place.
During the course of Hinduism, the local elements played a crucial role in forming the sacred.
During the Rigvedic Ages, Saraswati and Indus played a crucial role in forming the hymns and myths.
During the Vedic Ages, mainly Upanishads and Puranas, which occurred in the Gangatic Planes, Ganga and it's tributaries gained more prominence and importance.
Ancient Indians also claim to have found some medicinal and anti-bacterial properties for the water in Ganga, which has been somewhat corroborated by recent research.
