Well water and dioxygen.........

#### Explanation:

Hydrogen peroxide disproportionates according to the following reaction:

${H}_{2} {O}_{2} \rightarrow {H}_{2} O + \frac{1}{2} {O}_{2}$

The oxygen in hydrogen peroxide is formally oxidized from $- I$ to $0$ in oxygen gas, AND reduced from $- I$ to $- I I$ in water.

The simultaneous oxidation and reduction is formally known as a $\text{disproportionation reaction. }$
