Foam Breakers for air / foam drilling

We are using air foam to drill limestone surface hole. Unfortunately our next well is in close proximity to surface waters used for drinking by the local community. Although non toxic, foam in the water streams has a serious visual impact which requires substantial mitigation measures and potential compensation payouts.

Does anyone have any experience of any non toxic products or other methods to break or contain the foams to minimise the chance of them entering the nearby water systems?
