Hi guys, near where i live is a national Park and there is a lot of springs and pleanty of people are coming to take somw water to home becouse our tap water is really bad.On one of them is a sign that water is for drinking but it's rich with nitrates. I checked EC and its 515ppm and i don't know can i use that water since is rich with nitrates, especialy now when i have N excess?
Thanks.
