I really do like this one, too. Gives off the kind of vibe I was looking for. I do have some suggestions, though:
The line "The chamber holding RPC-005 must be located at least 100 kilometers from any large body of saltwater," being thrown in at the end of containment procedures instead of with the other water proximity-related requirements makes it seems like an afterthought.
Technically water is an "organic liquid," so it might be better to say "bodily fluids" instead, since the only examples are blood and sweat. The term "organic liquid" is also commonly applied to industrial products.
You refer to other people as "subjects" when explaining the anomaly's effects later in the article, so it might be better to change "alters people's perception" to "alters subjects' perception."
Just for syntax reasons, I'd recommend changing "intimidation, lure or disguise measure" to "intimidation measure, lure or disguise."
Just for clarity's sake, I'd also recommend adding "in height" to "Elderly woman measuring approximately 145 cm." so it says "Elderly woman measuring approximately 145 cm. in height."
Really good job though. This is a solid SCP that doesn't need much polishing, so kudos.
