Seeking Formula to separate cells that contain specific terms

I have thousands of data entries (each in their own row, all in one column) and need to separate the basic info. In the example below, say you want to isolate the Town names by entering a formula that can produce a TRUE or FALSE result. Is there a way to use the FIND function and a pool of terms to isolate cells that contain excess data (i.e.- produce a FALSE result for cells containing any words from a term pool like : "Police, Park, Power, Water, Community, Bakery, Grocery, Field, Garden, Post Office, School" etc... ) ?
