ESF on Half-Life: Source?

[Windmill]

Sorry, the forums will not allow me to post in the Help section. Is ESF compatible with Half-Life: Source? That is the only copy of Half-Life 1 I own, unfortunately. I've researched around but it doesn't seem like there's an open answer (that I've seen at least).

Thanks for your time.
