639 Symposium on Remote Sensing for Resources Development and Environmental Management / Enschede / August 1986 Remote sensing assessment of environmental impacts caused by phosphat industry destructive influence S.C.Mularz University of Mining and Metallurgy, Poland ABSTRACT: A number of remote sensing techniques, such as colour aerial photography, black and white aerial photography and thermal imaging have been used to detect adverse environ mental impacts associated with the location of the phosphogypsum dump area. As an effect of processing and interpreting remotly sensed data, assessments of water pollution, solid waste disposal impacts on toe-failure deformations zones and the degree of vegetation co ver damages, have been specified. Results of experiments indicate that remote sensing me thods are an irreplaceable tool to solve environmental monitoring, as well as planning problems. Wide-area repetitive coverage by remote sensors provides information which is not readily available by conventional measuring techniques. 1 INTRODUCTION In a wet-process of phosphoric acid produ ction from apatite and phosphorite, phos phogypsum is generated as the major by-pro duct. In such technology large quantities of waste are produced(as a rule, 5-5 tons of phosphogypsum are produced for each ton of phosphoric acid produced). Phosphogypsum is composed mainly of gyp sum (CaSG^. 211^0 ) , which makes 93-95$ of total waste mass. The remaining 5-7$ is com posed od different admixtures like: noncom- bined molecules of phosphoric acid and phos phates (together 0.4 - 1.5$ of P^O ) * sili ceous acid, fluorine compounds, organic mat ter and also some radioactive substances. Phosphogypsum is very burdensome substance to the natural environment, and causes its degradation because of harmful contamina tion. Therefore, it is necessary to study and to monitor environmental changes occur- ing in phosphogypsum dumping areas. Remote sensing techniques are very useful for this purpose, as they make it possible to record the complex data, which is nece ssary for a thourough interpretation of na tural conditions. They also make a qualita tive and quantitative analysis of phenome- nas and processes that happen on dumping and adjacent regions, possible. The results of investigations, based on remote sensing techniques, of a phospho gypsum dumping area of a chemical factory, near Szczecin, are presented in the paper. Presently, 3-5 million tons of waste are acumullated here annually, which accounts for 70$ of the phosphogypsum generated in Poland. The main purpose of the investigation was to asses the usefulness of remote sensing techniques for: - the creation of a complex environmental monitoring system for the dumping area, - periodically mapping the progress in dumping operations, - the assessement of the hazard for st^ff, heaping machines and constructions, which are located close to the dump area. The objective of the research reported here was to also examine the environmental dama ges in the dump influence zone. 2 STUDY AREA, PROBLEM DEFINITION AND DATA Geographically, the dumping area is loca ted near the Odra river estuary, north of Szczecin ( Figure 1). 25 km ■ - —» Figure 1. Location of the study area on Landsat MSS ( Band 4) image portion. Morphologically,it lays on the flooding terrace of the Odra river. Originally the terrain was flat, with an average height of 1 m below sea level. Considering the geolo gical conditions, it was found that the dump subgrade is composed of holocene deposits, which are organic in the upper part (peats, organic outwashes) and, in the lower part, consist of sand and gravel layers. They are underlaid by older pleistocene clays, some times interbeded with sands. The holocene deposits are 8-11 meters thick, locally up to 15 meters. The pleistocene deposits are several tenths of a meter in thickness. From a geotechnical point of view the up per organic layer is very weak, practically unstable, easy to defOrmate under loading. This feature of the base was confirmed by toe-failure which occurs on a large scale during the dump formation. As a result of
