Pampa is the third-longest river in Kerala after Periyar, spanning about 176 km in total length and enriched by 13 tributary streams (Azhuthayar, Kakkiyar, Kakkattar, Kallar, AadhiPamba, Varattar, Kuttemperoor, Utharappalliyar, Kolarayar, Njunungar, Madatharuvi, Kozhithodu, and Thanungattilthodu). The river is known as the ‘DakshinaBhageerathi’, which emanates from Pulachimala on Peerumedu upper plateau of the Idukki district and flows through the midlands of the Pathanamthitta district, enriches the lowlands of Alappuzha-Kuttanadu, and eventually drains into Vembanad lake that joins the Arabian sea. The Pampa River is famous mainly for its sacredness associated with the Sabarimala Temple and Maramon Church pilgrimage. Millions of devotees visit Sabarimala to carry out the ultimate rituals ‘The Holy Dip’ every year with the act of disposing of their clothes in the flowing river tainting the river significantly. Due to modern agricultural practices along the river basin region from the midstream to downstream areas, excess pesticides, herbicides, and fertilizer effluents are discharged into the river, eventually ensuing in heavy metal accumulation, eutrophication, and algal blooms. There is a substantial degree of sand mining from the riverbanks of Pampa.
