don't shave in a pond, creek, stream as if yo use shaving foam it may pollute the local wildlife. Take some water from the pond, creek, stream, shave at least 100m away from pond, creek, stream and throw water away at least 100m from pond, creek, stream.
Also try and get a bio degradable shaving foam if applicable.
