Treating your well once or twice a year has proven effective in reducing or eliminating the “rotten egg smell” which is caused by hydrogen sulfide gas. Continue reading “Rotten Egg Smell In Your Tap Water”
Disinfecting Water Well
How Much 35% Hydrogen Peroxide To Use In Well Disinfection
The amount of 35% Hydrogen Peroxide to use when disinfecting or cleaning a well will depend on a few factors.
- The depth of the well.
- The water level.
- The diameter of the well.
- What contaminants are present.
- The amount of each contaminant.
- The construction material of the well components.
Dilution Reference Chart
Diluting 35% Food Grade Hydrogen Peroxide is easy.
1 oz 35% diluted with 11 oz distilled water 3%
1 oz 35% diluted with 22 oz distilled water 1.5%
10 oz 35% diluted with 118 oz distilled water 3%
I will expand this post soon.
Shelf Life 35% Hydrogen Peroxide
What is the shelf life of 35% Hydrogen peroxide? It depends how we define shelf life. Hydrogen peroxide does not spoil or “go bad”. Our 35% Hydrogen Peroxide does not have unwanted added stabilizers and is not “stabilized” with added chemicals or toxic heavy metals. For this reason on average a 1%-1.5% loss over 12 months may be possible.
Our peroxides do have a two year expiration date from the date of production. Federal regulations require organic food producers and packaging facilities, when using hydrogen peroxide that the hydrogen peroxide must meet standards defined in the Food Contact Chemical Codex and can not be less than 33.5%. It is likely that over a two year period 35% hydrogen peroxide may have dropped below this threshold.
Hydrogen peroxide at 33.5% is still very strong and usable for home use. We certainly encourage customers to utilize the benefits of their peroxide however if you find a bottle and six years has passed use our concentration calculator and make adjustments when diluting to take in consideration any estimated drop in strength.
Our peroxide is always fresh and we never store our inventory for extended time. We are constantly evaluating demand, paired with our procurement. This guarantees customers will receive high quality and strong 35% hydrogen peroxide. We do multiple batch tests during certification and require our 35% to be 35% or greater yet can not exceed 35.9%. Most batches test between 35.2% and 35.7%.
Storing in a refrigerator or freezer can help prevent degradation over time although a cool dark storage is adequate. 35% hydrogen peroxide will freeze at -35C / -31F which is well below temperatures common for residential freezers.
Remember to store away from children.
