Heterogeneous mixture term best describes the matter in the bottle.

Explanation:

In a heterogeneous mixture, the substances do not merge smoothly throughout, and the individual particles that the mixture comprise can be detected easily. The Heterogeneous mixtures can typically be segregated back into their individual components through any chemical or physical processes.

This Heterogeneous mixture are of two type namely suspensions and colloids. Suspension are particles in the mixtures settles down when left undisturbed for certain time period whereas in colloids the particles do not settle down. In Darryl bottle ,Though the water seems to be clear the dirt is settled at the bottom after some time . So it must be an heterogeneous mixture.
