Let the bleach remain in the system for a minimum of 12 hours; 24 hours is best. The longer the bleach remains in the system, the more time the chlorine has to destroy the bacteria.
Wait 48-72 hours until you wash your hair.
How long should I wait to wash my hair after bleaching? Do not wash your hair within the first 72 hours of bleaching your hair. Wait as long as possible, ideally five to seven days. Give hair a minimum of 48 hours before washing. Waiting allows the colour to fully develop.
Run the water to flush the bleach solution out of the well. Monitor the process, it can take 30 minutes to 24 hours or more to flush all of the bleach solution from the well. Use a chlorine test strip to verify that water coming from the outside faucet or yard hydrant is free from any bleach solution.
Wait at least 7 to 10 days to test the water after disinfection to ensure that the chlorine has been thoroughly flushed from the system. Until well water has been tested, boil it (rolling boil for 1 minute) before using or use another alternative water source.
Very few wells will need more than one gallon of bleach. Using more bleach than necessary will not disinfect the water faster, may cause corrosion of the steel casing and will hinder the disinfection effectiveness. To calculate the amount of bleach needed, you need to know the well's depth and static water level.
Wait one to two weeks after shock chlorinating the water supply system to re- test for total coliform and E. coli bacteria. Follow sample collection instructions carefully. If the test results show the absence of coliform bacteria, the water is safe to drink.
For wells 4” in diameter or less, we recommend that one quart of common household bleach or two cups of pool chlorine be poured down the well casing for each 20' of depth. 5. For wells 6” or 8” in diameter, one gallon of bleach or ½ gallon of pool chlorine should be poured down the well casing for each 20' of depth.
Just subtract the depth to the water from the total depth of the well. Multiply that by 0.65 for a 4-inch well or 1.47 for a 6-inch well. Then add another 100 gallons for the tank and hot water heater. Use 3 pints of chlorine bleach for every 100 gallons.
Wait 48-72 hours to wash your hair after bleaching it. Bleaching causes your hair cuticles to swell, so washing your hair before they shrink can affect the color. Hair expert Frankie Sanderson says that “within two days, [the cuticles] should have come back down.”
Avoid going outside in the sun right after getting bleached to prevent skin irritation and redness. Chemical-intensive beauty procedures like facials should be avoided with face bleaching.
Bleach solutions require a full 10 minutes of contact time to ensure complete disinfection. If bleach solution evaporates in less than 10 minutes, a greater volume of solution should be applied. 5. After disinfection with bleach solutions, surfaces should be rinsed and dried.
Overall, hydrogen peroxide is more expensive than chlorine and works best when iron and sulfur are present in the water supply. Since it works faster than chlorine, no contact tank is required. Additionally, H2O2 is effective at a more comprehensive pH range, meaning that it is more effective on more types of water.
Pumps should not run longer for 1 or 2 minutes. The reason is this could cause motor damage.
With shock chlorination, the entire system (from the water-bearing formation, through the well bore and the distribution system) is exposed to water that has a concentration of chlorine strong enough to kill iron and sulfate-reducing bacteria.
Once you have shocked a well, avoid bathing or doing laundry for at least 24 hours, if not longer. The amount of bleach needed to shock a well depends on the size of your well. you need to calculate how much bleach you need.
The frequency of shock chlorination depends on several factors, including the type of well, water usage, and local environmental conditions. Generally, it is recommended to chlorinate your well at least once a year. However, certain situations may require more frequent chlorination.
If your well is very deep, it may take a long time for the bleach to reach the taps. Let the bleach mixture sit in the well and pipes for at least 6 hours, or overnight if possible. Do not drink this water. After the waiting time has passed, turn on the electricity to the pump.
Note: Liquid bleach should not be used with a steel well casing; it can break loose accumulated corrosion and cause pump failure.
Once the odor of chlorine is detected, turn off the hose. If you have a water softener, activated carbon or other water treatment system put it on bypass NOW so the chlorine will not damage the unit or be removed by it.
Allow the chlorinated water to stand in the well and the entire water system for a minimum of 12 hours (24 hours is recommended). During this time the system should be considered unusable - with the exception of moderate toilet use.
How Often Should I Shock My Well? It depends on the level of contamination. Generally, it should be done annually or when bacteria are detected. Since you can't see, smell, or taste bacteria in your water, you'll need to test your well water often.
Shocking is crucial for removing any pathogens in the water and making a pool safe for swimming. It also involves using heavy-duty chemicals, including chlorine, so it's best to wait at least 24 hours after you shock a pool to go swimming. Going in too soon can potentially cause skin, eye, and even lung problems.
