Run sites appear to have undergone the greatest amount of recovery, 

 although they lack the number of taxa one would expect of an 

 unpolluted stream. Tick lower and Minkers upper would be next in 

 order from unpolluted to polluted, both having a moderate load of 

 compensated noncarbonate conductivity and lacking the abundance 

 of meiofauna expected of an unpolluted stream but both showing 

 greatest simileirity of the meiofaunal taxa present with the meiofauna 

 of unpolluted streams or those sites well along in the recovery 

 process. Next in order would be Minkers lower and Sandy lower, 

 both of which have abundant meiofauna, an intermediate to 

 depressed number of taxa, and a moderate to less than moderate load 

 of compensated noncarbonate conductivity. The meiofauna of each 

 of these two sites is most similar, each in its own way, to one of the 

 Raccoon Creek sites. Finally, and most anomalous, is the Tick upper 

 site which, aside from the low measured total conductivity, gives 

 some indications that it may have been adversely affected by the 

 recently stripped and reclaimed area at its headwaters.

 Research and Technology, U. S. Department of Interior, through the 

 Ohio Water Resources Center. We wish to thank George Billy, Ohio 

 Department of Natural Resources, Athens; Roger Jewell, Wayne 

 National Forest, Athens; and James Tong, Department of Chemistry, 

 Ohio University, Athens, for consultations regarding the nature and 

 extent of acid mine pollution in southeastern Ohio. We are 

 particularly indebted to Roger Jewell for suggesting the Raccoon 

 Creek and Tick Ridge collecting sites. Our thanks go to Deborah 

 Zmarzly, Lynn Sarles, and Stuart Arkett for aiding in various of the 

 field collections.
