A moisture collection apparatus is provided to collect and store percolating ground water for increased water absorption by foliage growing above the moisture collection apparatus. Namely, relative scanning is carried out between a substrate and a function liquid droplet ejection head having introduced therein a light function material is selectively ejected toward the emitting function material. This stage allows for improved removal of certain toxins in the fluid, such as protein-bound substances that disassociate more readily from proteins at lower pH. A programming arrangement is provided separate from the device for customizing a read channel within the Storage Element.
