At Lafayette College (It's in PA, not the south! People always ask me that, so I thought I'd clarify):
Sororities:
Alpha Gamma Delta
Alpha Phi
Delta Delta Delta
Delta Gamma
Kappa Kappa Gamma
Pi Beta Phi
Fraternities:
Chi Phi
Delta Kappa Epsilon
Delta Upsilon
FIJI
Kappa Delta Rho
Phi Kappa Psi
Theta Chi
Zeta Psi
I believe that there are a few people trying to colonize a chapter of Alpha Phi Alpha, too, but don't quote me on that. Some people were trying to recolonize the Alpha chapter of Alpha Phi Omega during my junior and senior years, but that fell through. While I was in college, Sigma Alpha Epsilon and Theta Delta Chi were both kicked out, and Sigma Nu and Sigma Chi were kicked out 1-2 years earlier. That's 4 chapters in about 6 years! Lafayette is becoming very anti-greek.
