Date: May 2000 Creator: Ochandio, Mario Roberto Description:
This study assessed the water quality of the Elm Fork Watershed
with regards to the herbicide Atrazine. Atrazine is a potential
environmental endocrine disruptor and carcinogen. Overall,
concentrations were lower than the four-quarter drinking water
average of 3 µg/Lthe Maximum Contaminant Level set by the USEPA.
However, three creek stations had four-quarter average
concentrations greater than 3 µg/L, and virtually all samples
exceeded the 0.1 µg/L standard set in Europe [1,2].
Statistically significant differences in concentrations were
detected between the 27 sampling stations and areas of high
concentrations were identified. However correlations between
Atrazine concentrations and land-use and precipitation were not
statistically significant. Further analysis with more detailed
data should be conducted before any relationships are discarded.
