Sediment or dirt in water from a well

Gritty or dirty well water usually means sediment is getting past the well's filtration point, often from a failing screen, pump issue, or lack of a sediment filter.

Symptoms

  • Visible grit or sand settling in a glass of water
  • Water looks cloudy or slightly tan
  • Sediment clogs faucet aerators frequently
  • Problem worsens after heavy rain or well pump changes

Likely causes

  • CommonWorn or damaged well screen allowing sediment intrusionThe screen at the bottom of the well is meant to filter out sand and sediment, and it can degrade or crack over time.
  • CommonNo sediment filter installed on the household sideMany well systems benefit from a dedicated sediment filter even with a properly functioning well screen.
  • PossiblePump positioned too close to the bottom of the well, stirring sedimentIf the pump intake sits too low, it can pull in settled sediment from the well bottom.
  • Less commonRecent well work or pump replacement disturbing sediment temporarilySediment can be stirred up right after any physical work on the well and usually settles within days.

What to do

  1. Clean faucet aerators and check how much sediment collects over a few days to gauge severity.
  2. If a whole-house sediment filter isn't already installed, consider adding one on the main line after the pressure tank.
  3. Check the filter regularly at first to see how quickly it's loading with sediment, which helps establish a replacement schedule.
  4. If sediment appeared suddenly after recent well or pump work, give it a few days to clear as things settle, since disturbance-related sediment often resolves on its own.
  5. For persistent or worsening sediment, have a well contractor inspect the well screen and pump placement.
  6. A contractor can also assess whether the well needs to be cleaned out (bailed) if significant sediment has accumulated at the bottom.
  7. Consider periodic well water testing for sediment along with other quality parameters as part of routine well maintenance.

When to call a pro

Call a well contractor if sediment is persistent or worsening, since it may indicate a screen problem or pump placement issue requiring well access.
