Data, secured by questionnaire from single household dwelling units in Warwick, Rhode Island, were used to ascertain differences among social status groups with respect to attitudes and conceptualization pertaining to water pollution and water supply. A social status index was used to delineate three status groups having high, middle, and low rank (designated as groups I, II, and III, respectively). Tension related to water pollution was experienced in each status group; however, it was greater for groups of high and middle status than for the low status group and differed significantly only between groups I and III. An information index was used to measure the general level of knowledge about pollution and supply of ground water and surface water. No significant differences were found among status groups. The affirmation of belief in man's control of water pollution and supply was greater in the higher status groups than in the lower ones. A preponderance of respondents agreed that control of situations and responsibility for them are associated. Beliefs under conditions of no conflict and conditions of conflict differed significantly.
