<br /> I=The analyte concentration was reported from a dlkried sample.Baseline levels for tOtel phosphorous were not implemented until August 23,2004.
<br /> g-Groundwater sample was analyzed for orthophosphate by EPA method 365.2.
<br /> It=Groundwater sample was analyzed for orthophosphate by EPA methods 365.2 and 300.0.Analytical results by EPA method 300.0 am noted len parentheses.The discrepancies between the ortho-phosphate remits by
<br /> method 300.0 and method 3652 are beloved to be due to high levels of turbidilyin the sample matrix,which results In erroneously high results when using mfilhOd 365.2
