SEASONALITY OF TOTAL FATTY ACID PROFILES IN ACID MINE DRAINAGE IMPAIRED STREAMS
Pre-regulation coal mining and subsequent acid mine drainage (AMD) has drastically altered stream quality in the Appalachian region of the United States. Streams impaired by AMD often demonstrate lower pH, increased specific conductance, and high dissolved metal concentrations compared with streams not receiving AMD. The purpose of this study was two-fold, (1) to use fatty acid profiles to distinguish between biofilm communities in AMD impaired and unimpaired streams and (2) to determine the consistency of results throughout the summer sampling period. Fatty acid profiles easily and rapidly separated biofilm communities into their respective categories, either impaired by AMD or unimpaired, using multivariate statistical approaches. Fatty acid profiles were similar within stream type throughout the summer sampling season and the profiles were correlated with pH and specific conductance. The results of this study show that fatty acid profiles can rapidly and accurately categorize the biofilm community as a result of environmental impairment during the sampling season for biomonitoring.
