Toxic foam covers sacred Indian river

In India this week, hundreds of devotees waded in a toxic river to offer prayers during a Hindu festival.
Many are worried about the high pollution levels in the Yamuna, one of the country's most sacred rivers.

Toxic foam has been floating down the waterway that runs through New Delhi since earlier in the week. Despite the health risks, worshippers took a holy dip to celebrate the four-day festival.

Experts say the foam is caused by the discharge of untreated sewage and industrial waste. There are 35 sewage treatment plants in the capital, but 25 do not meet the required standards. Three-fourths of the pollution is concentrated in a section that flows through the capital.

Water pollution is a major concern in India in addition to air pollution.
Officials of states that share the river are blaming each other for the failure to tackle the problem.
