The Ulhas river has turned highly turbid, reducing treated-water supply by roughly 20% to Badlapur, Ambernath, Ulhasnagar and Kalyan. The Maharashtra Jeevan Pradhikaran plant normally treats 140 million litres per day but is supplying only 110-120 MLD, official Suresh Kadri told Hindustan Times. Officials suspect illegal sand-mining during the Ganesh festival may have disturbed the riverbed.

The Times of India reports that the Ulhas Bachao Kriti Samiti conducted a two-day inspection at 28 locations between Kalyan and Karjat. They documented hill cutting, tree felling and construction activity, identifying Pimploli near Karjat as a key area. The committee said its observations are preliminary and require scientific testing. It has sought a joint probe by the MPCB, district administration and forest department. Activists will submit findings, photographs and samples to the authorities.
Hindustan Times and Times of India both report the same water-supply disruption but frame its cause differently. HT leads with suspected illegal sand-mining during the Ganesh festival, which a single official says is unconfirmed. TOI leads with activist findings of hill cutting and construction activity along the upper reaches, backed by a two-day inspection at 28 sites. TOI names a specific location (Pimploli) and a development project, while HT leaves the cause vague. The balanced read: the turbidity has multiple possible sources. The activists have promised to submit their evidence to the MPCB and other agencies, which will determine the next step.
