To find the combined capacity of the two pools, you need to add the capacities together:

1. Olympic size pool: \( 8.12 \times 10^5 \) gallons
2. Smaller pool: \( 5.27 \times 10^5 \) gallons

Now, we can perform the addition:

\[
8.12 \times 10^5 + 5.27 \times 10^5 = (8.12 + 5.27) \times 10^5
\]

Calculating the addition within the parentheses:

\[
8.12 + 5.27 = 13.39
\]

So now we have:

\[
13.39 \times 10^5
\]

Since \( 13.39 \times 10^5 \) can be expressed in scientific notation, it can be converted as follows:

\[
13.39 \times 10^5 = 1.339 \times 10^6
\]

Thus, the combined capacity of the pools is:

\[
\boxed{1.339 \times 10^6} \text{ gallons}
\]

The correct answer is **B**.
