If non-biodegradable substances are put into water, a very unpleasant foaming may occur—for example, at weirs and over patches of rough water.
A higher level of biodegradability would also reduce the likelihood of foaming in rivers, a phenomenon currently under investigation by the water research centre.
The idea that everyone is foaming at the mouth to get regional assemblies misreads the popular mood.
Local authorities which try to break down this foaming agent are put to considerable expense.
I understand that the manufacturers are still trying to develop substances suitable for industrial use in place of those that mainly cause the foaming.
This should help a little to reduce foaming.
Some can even be caught foaming at the mouth.
Except in some isolated circumstances there are now no serious problems of foaming.
