The VLA was used to survey the fields of the three clusters of galaxies 0016 + 16, Abell 665, and Abell 2218 for radio sources that might contaminate observations of the Sunyaev-Zel'dovich effect. Surveys at 1440 and 4860 MHz covering the full fields were followed by pointed observations at 14,940 MHz for the brighter sources. Several of the sources are significant contaminants of Sunyaev-Zel'dovich observations. Corrections for the contaminating sources, and the best observing locations in the three clusters, may be found on the basis of the survey; as an example, the corrections to the results of Birkinshaw et al. (1984) are calculated. Each of the clusters appears to possess a faint central steep-spectrum extended source. It is speculated that the presence of a radio halo source is correlated with the existence of a strong Sunyaev-Zel'dovich effect. 25 refs.
