The Regional Aquifer-System Analysis (RASA) Program was started in 1978 following a congressional mandate to develop quantitative appraisals of the major groundwater systems of the United States. The RASA Program represents a systematic effort to study a number of the Nation's most important aquifer systems, which in aggregate underlie much of the country and which represent an important component of the Nation's total water supply. In general, the boundaries of these studies are identified by the hydrologic extent of each system and accordingly transcend the political subdivisions to which investigations have often arbitrarily been limited in the past. The broad objective for each study is to assemble geologic, hydrologic, and geochemical information, to analyze and develop an understanding of the system, and to develop predictive capabilities that will contribute to the effective management of the system. The use of computer simulation is an important element of the RASA studies, both to develop an understanding of the natural, undisturbed hydrologic system and the changes brought about in it by human activities, and to provide a means of predicting the regional effects of future pumping or other stresses. The final interpretive results of the RASA Program are presented in a series of U.S. Geological Survey Professional Papers that describe the geology, hydrology, and geochemistry of each regional aquifer system. Each study within the RASA Program is assigned a single Professional Paper number, and where the volume of interpretive material warrants, separate topical chapters that consider the principal elements of the investigation may be published. The series of RASA interpretive reports begins with Professional Paper 1400 and thereafter will continue in numerical sequence as the interpretive products of subsequent studies become available.

“…The belt is nearly 19 miles long; and at Watch Hill, in the southwestern tip of Rhode Island, it extends into Block Island Sound. Upham (1879) suggested that this moraine is a continuation of the chain of morainic hills along the north shore of Long Island to which Veatch (1903) later gave the name Harbor Hill moraine. The Buzzards Bay moraine of southern Massachusetts (Woodworth and Wigglesworth, 1934) has been generally considered its continuation to the east ( fig.…”

Surficial geology of the Kingston quadrangle, Rhode Island

Evidence of only' 1 Pleistocene glaciation is recognized in the Kingston quadrangle, although exposures to the south on Block Island indicate that 2, and possibly 3, glaciations took place. The glacial drift in the Kingston quadrangle is divided into (a) that deposited by ice from the New England Upland and characterized by light-colored till made up of debris from the crystalline rock of the upland, and (b) that deposited by the Narragansett basin ice and characterized by dark-colored till derived from the distinctive rocks of the Narragansett basin. Although the division between the two drifts is relatively sharp, this fact does not denote separate ice sheets but rather different sectors of the same ice sheet whose flow paths crossed different rock terra nes. The recognition of Pleistocene ablation moraines is discussed because this type of deposit is of particular importance in the Kingston quadrangle. Deposits of ablation origin may be characterized by one or more of the following features: stratified till, deposits that show all degrees of sorting, interstratification of till and sorted drift, contorted bedding on a large scale, the occurrence of ice-fracture fillings, and the tendency for bedding of the more superficial strata to parallel the hummocky surface. The Charlestown moraine, the eastern third of which lies within the Kingston quadrangle, probably represents a marginal belt of ablation moraine that developed at the edge of the upland ice during a retreatal stillstand. The moraine consists largely of ridges and mounds; these are interpreted to be icefracture fillings and ice-block casts, respectively. The narrow belt of the Charlestown moraine merges on the east with a broad development of ablation moraine that is lower in elevation. This moraine, which is probably contemporaneous with the Charlestown moraine, was deposited on the Narragansett basin ice. The distribution of these moraines indicates that the Narragansett basin ice formed a lobate projection well beyond the front of the upland ice, when the latter stood at the Charlestown moraine. The ice receded from the area mostly by dowmvastage. Blocks of stagnant ice remained in the valleys after the hills were entirely exposed. Where ice was insulated by a blanket of thick moraine, its melting was retarded. Several of the ablation moraines, therefore, had cores of stagnant ice that lasted long after ice to the north had melted away. Glacial melt waters transported and deposited morainic debris between and over much of the stagnant ice in low-lying places. The courses taken by melt-water drainage changed as deglaciation progressed. Thus drainage of the area north of the Charlestown 34.1

Quaternary stratigraphy in the northeastern region has developed slowly because researchers have been few and because quartzose bedrock and extensive forest have inhibited field study. The earliest stratigraphic studies antedated 1850, but in most parts of the region the stratigraphic units still recognized today were identified in the present century. Ancient and modern sequences are generalized and are shown in charts.
