Statistical Notes: (Stalisical catculations were performed using Washington Department d Ecologj's MTCASlat Excel V.5 Macro (Module 2.1). downloaded lrom their web site.)
Max~mum and minlmum concentrattons are based on detected values only.
Range of reponing limits (RL) are based on resulh reponed as not detected.
Distribution is determined based on the MTCA slal program by analyzing the data through the 'W-Tesr or 'D'Agostino's tesr. Where data is nd lognormally nor normally dtshlbuted, the distribution is noted as 'Neithef
When approximate dish~bution is reponed as -oelthef. the maximum concenhalion is reported as the 95% UCL and is presented in BOLD lonl.
The mean is an arithmetic mean if data are normally distributed or 11 distribution is indicated as 'Neithef. The reponed mean for lognormally distributed data is a lognormal mean.
Statistical analysis was not performed on data sets where 50% or greater of the results were reported as not detected. Only maximum and minimum concentrations are reported, if applicable.
For these data sets, a calculated median is based on detected values only.
