I have always had sediment in my water here and lots of things contribute to it. Originally the well was 180 feet. Some time around 1998 it went try do to a drought and had it drilled to about 240. The casing does not go all the way down. Since then the sediment can be worse than it was. It mostly happens when it rains, the heavier the rain the more sediment it gets. My well guy figures that when the ground water level goes up due to rain that water pours into the well from higher inlets and this stirs up the water. A week without rain and there's no sediment.
I have a hole house filter, three 20 micron filters in parallel.
Also, if you just replaced the pump, that could have had something to do with it. I had my pump replaced 2 years ago, it was running almost continuously to get and keep my system up to pressure. A pump that is running continuously can stir things up.
Like other said, wait a few days and see if it clears. If it's raining now wait a few days after the rain has stopped.
