confirm meaning of negative water depletion impacts #70
Hi @DEQpcanepa , recently we switched the water metric used in WIC from "water consumption" to "water depletion". I noticed some interesting numbers and just wanted to confirm I understood their physical basis.
As shown in the attached screenshot, sometimes water depletion impacts are negative. This is especially notable for incineration of certain materials, such as plastic and wood. Of course when anything solid and organic is burned, it produces H20 and CO2, and is thereby generating water vapor that can go back into the environment. Is this the reason for negative water depletion numbers?
