Hi Karen

 

The cause may be natural – bacteriological.

 

See link for more information – section on oily film:

If linked to bacterial growth then be aware that under certain conditions the bacteria can flourish to form a mass that is gelatinous. This mass can cause blockages in confined spaces such as culverts.

 

Kind regards

Subject: Orange water

 

Hello all,

 

I have three different locations around the canals in the north where we are seeing orange water ponding adjacent – I attach  a couple of photos.  My first thoughts were possibly mining related but analysis has shown that all metals (including iron) are around or below limits of detection.  Has anyone any ideas what this might be please?  Thank you
