If you get your water from a private well, black and brown pieces of sand and silt may be present in your tap water. These are caused by minerals, soil or mud, or organic matter and are not harmful. You can treat black sediment by installing a sediment filter or a water treatment system.
Every well is different as far as how long it takes to clear. Some wells need only a few minutes, others can take days before it is back to normal.
Depending on the size and depth of the well and extent of contamination, pumping times will vary; it may take thirty minutes, or it could take several hours or days until the water runs clear.
Well-Known Member I suspect you have a leak in the line coming from the well. When the pump shuts off it sucks dirty ground water into the pipe, and when the pump starts it pushes the dirty water into your system. I had a similar thing happen once.
If your house has access to well water or you've connected it to a well source yourself, chances are that the black particles in tap water are just bits of dark sand or silt. If the silt isn't as tightly packed or well mixed into a hard layer, the bits get pulled into the water supply to your home.

Solution? Flush your hot water heater if needed, inspect your piping, clean your aerators on your faucets and then try flushing your cold water for 5 minutes and it should clear up the discolored water.
To remove sediment from your well water supply, you can try a separation filter, a centrifugal system, whole house filtration systems, or even a water softener system. Learn more about how a water test can detect sediment in your well water, and find the best system to help you purify your well water supply.
A solid like fine sand or silt can take seconds to minutes to settle out of liquid suspension. However, fine silts and colloids can take weeks or even years to fall out of suspension naturally. Of course, companies and municipalities can't wait years or even hours for solids to settle naturally.
Rainwater and snowmelt can carry contaminants and microorganisms that may leave your drinking water looking dirty. * This water can mix with your well's source, such as an underground aquifer, or it may wash directly into your well system. Either way, the result can be unpleasant — and a little alarming.
In many cases of sudden sediment appearance, the culprit involves a well screen that has become excessively damaged or degraded. Such a screen can no longer prevent particulate matter from being sucked up through your well pump. Fortunately, most contractors can replace a well screen with relatively little difficulty.
Well pumps left to run for extended periods will overheat and burn out. Frequent or increased pre-priming needs checking by professionals. Contact our team of professional pump specialists to check out your foot valve soonest. This will avoid damage.
To remove sediment, your well should be pumped for a minimum of 48 hours at a rate greater than the maximum pumping rate expected when the system is operating normally. Throughout the pumping process, the pressure gauge on your cold water tank should read 20 psi or less.
Sediment Filters: Installing a sediment filter in your main water line can help trap and remove suspended particles from your water. Depending on the type of sediment and its size, you might need a mesh screen filter or a more intricate water filter system.
Newly drilled wells will need to be run at least 24 hours before testing. This allows the well to "settle in" so that the water being tested is more indicative of the water you will be using.
Treatment options
Sediment and particulate can be removed from a water supply using mechanical filtration. Suspended particles are removed as water flows through a filter cartridge, inside of a filter housing. Sediment filters can be installed anywhere in the home but point-of-entry is recommended.
Cloudy water can also result from the suspension of the smallest soil particle, clay. Suspension means that the clay particle will not settle and can give the water a muddy appearance. Cloudy water from wind, rain or animal activity should clear within a few days, however if the source is suspended clays may not.
The physical process of sedimentation (the act of depositing sediment) has applications in water treatment, whereby gravity acts to remove suspended solids from water. Solid particles entrained by the turbulence of moving water may be removed naturally by sedimentation in the still water of lakes and oceans.
It can take up to 30 days after a well is drilled and the water is used daily before the well settles and sediments are gone. o Older wells, or wells drilled in loose bedrock, may experience sediment piling up at the bottom of a well, which might then be pumped into the plumbing system. o Damaged or degraded well ...
Vinegar is part of clearing and cleaning a clogged drain, and it's also helpful in removing sediment from water heaters.
While sediment in well water doesn't typically pose any direct health threats, it can wreak havoc on plumbing, fixtures, and appliances if left unresolved. Sediment particles can clog pipes, leading to restricted water flow and lower water pressure. Why Is There Sediment In My Well Water?
Re: Well Water - black residue
Manganese is pretty common in well water and can leave a black stain. It's not a health concern but has a metallic taste.
Begin by pouring up to a whole box of baking soda down the drain, depending on the severity of the slime. Then pour in the vinegar, up to half a bottle. You should hear or see the fizzing. Let it react for about five minutes, then slowly pour the boiling water down the drain.
