About three weeks after the grounding, the Coast Guard reported no 



more floating oil in the area. By that date, a total amount of approx- 



3 

 imately 1700 m of liquid material, including oil, water, debris, etc., 



had been recovered. Taking into account that samples of the spilled oil 



contained 18 to 76% water, the Coast Guard estimated that 600 to 700 



tons of whole oil were actually recovered. It is difficult to determine 



the quantity of the remaining oil because accurate tank soundings were 



not available. However, a reasonable estimate could be made that the 



total volume of the spill was somewhat larger than 1000 tons (Table 



1.1). This implies that about 400 tons were left in the environment 



after the initial clean-up operation. Some of this oil could be found 



adhering to rocks, stones, and mud beaches along 18km of shoreline. The 



area of impact is shown in Figure 4.10.
