I thought it was a strange way to begin a story with

"The river began turning the color of a nice marinara sauce on Thursday".

Looks like a typical Australian inland river full of soil particles from bank erosion.

Like the colour of a nice Aussie National pie with tomoto sauce, minus the pastry.

But quite seriously, I hope the locals who are gathering samples aren't drinking or bathing in it either, just in case.

It can't be due entirely to sediment/sand.

It actually looks like iron oxide which is a common problem in some streams here as a leachate from natural ironstone deposits.

Could also be some sort of microbial activity.

Whatever it doesn't look healthy and I'd be surprised if the extreme urbanisation and industrialisation of the banks in that area isn't a major factor.
