Potassium ferricyanide(III) is a potassium salt widely employed as an external indicator in potassium dichromate titrations. A sensor containing potassium ferricyanide assisted enzyme electrode for estimating maltose and glucose in samples has been reported. Addition of potassium ferricyanide in the catholyte can improve the generation of power in microbial fuel cells (MFCs).

This likely means that your water contains some iron (II) (i.e., ferrous iron). Potassium ferricyanide and hydrochloric acid are actually the reagents typically used to demonstrate ferrous salts using the Turnbull Blue reaction.
There are many variations on the basic Turnbull Blue technique. A commonly performed procedure is the procedure of Lillie and Geer. See Lillie, R.D. & Geer, J.C.

The rostromedial tegmental nucleus (RMTg), a GABAergic afferent to midbrain dopamine neurons, encodes aversive stimuli and inhibits motor responses.
Separate studies have implicated the lateral habenula (LHb) or amygdala-related regions in processing aversive stimuli, but their relationships to each other and to appetitive motivational systems are poorly understood. We show that neurons in the recently identified GABAergic rostromedial tegmental…
