Expressing disappointment over high levels of pollution in the Yamuna, the Supreme Court on Tuesday pulled up the Delhi, Haryana and Uttar Pradesh governments for little being done in the past 18 years for cleansing the river despite over `4,400 crores being spent for the purpose.

“All the agencies have spent crores of rupees. What is the purpose? What work has been done ultimately?” said a bench of justices Swatanter Kumar and M.B. Lokur.
