Estuary Model Tests Expedite Prototype Studies of Pollution A. JOEL KAPLOVSKY, Director Delaware Water Pollution Commission Dover, Delaware In recent years added emphasis has been placed upon the need for knowledge about the assimilative capacity of estuaries. The increasing rate of industrial and population growth in the Coastal States of the Northeast,. the West Coast, and the South has "spotlighted" a need for cleaner estuarine waters especially in areas where the potentialities of recreation are reasonably great. The pollutional loadings attributed to this growth and development have begun to emphasize their presence in downstream areas heretofore unaffected by the various discharges. Pending water shortages in these areas and the need for multiple use have placed added emphasis upon water development and quality. Certain complexities and variables inherent in estuaries make the understanding of waste stabilization evaluation in such environments considerably more difficult than in streams subjected to one-directional flow. Similarities do exist in many estuaries; however, variations in width, depth, configuration and run-off makes it almost impossible to transfer completely knowledge from one estuarine study to another. In essence, each tidal stream must be given separate consideration since the dispersion characteristics which affect the movement of the waste discharges are essentially different. Fortunately, or unfortunately, as the case may be, some coastal streams are less complex with regard to stratification, lateral dispersion and other factors. Before one can intelligently evaluate waste stabilization in any tidal stream, the dispersion of a discharged material must be reasonably well known. It would be futile to attempt the application of known stabilization theory to a waste which is discharged into a system when little is known with regard to the distribution characteristics. Several proposals and theories (1), (15), (16), (18), have been set forth in the literature with regard to dispersion or circulation formulae for estuaries. Unfortunately, these proposals or theories have some application only in a specific estuary where the procedure was developed. Considerable effort of past research on estuaries has been directed toward providing a universal solution. In many cases, the solution to the more difficult variables has tended to create differences in the theory of solution among the various researchers. However, a closer scrutiny of the effect of these difficulty solvable variables upon the overall pollution problem has shown that in some areas little of the overall problem would be resolved if and when the complicated aspects were completely understood. If the rapid growth and development in the Delaware River Valley, and possibly in other similar areas, should continue, it is more important to the stream pollution administrator to have a solution to a present problem which represents a significant percentage of the loadings and resultant decomposition rather than to await a comparatively complete solution which mayor may- not be resolved in an indeterminate period of time. It is indeed possible that many of the variables or complications existing in other estuaries are not present in the Delaware River Basin. The dispersion - 193 -
