How to Calculate Hydrogen Peroxide Concentration for Well Water Treatment
Need to know how much water to add to dilute your hydrogen peroxide?
A common question we get is: “I had a question about diluting my 7% hydrogen peroxide. How much water would I have to add to the gallon to dilute it to 7000ppm or 12500 ppm.” 
This is a good question, and the first step is understanding how many PPM 7% peroxide is.
Since we want to solve for parts per million, 7% of 1,000,000 is 70,000. So 7% peroxide is just another way of saying 70,000 PPM. If you used the 7% solution without dilution, your solution strength would therefore by 70,000 PPM.
By adding 9 parts of water, for every 1 part 7% peroxide, you would end up with 7000 ppm.
