Oh no I've been poisoned

Oh no, I've been poisoned...
Poisoned by my water source.

Oh no, I've been poisoned...
Poisoned with some sort of alkaline.

Who is it who wants me dead?
He have caused my health to fade.
Alkaliness 10 out of 14 met,
Spiking healthy water that is fed.

Intentional or not,
Someone is at fault.
A negligence practice,
Of failure to notice.
