NOTES:
Analysis type based on distribution of compliance well dataset and percentage of nondetects.
1/2 detection limits were used for inter-well parametric and poisson prediction limits.
For non-parametric prediction limits dection limits were used for inter-well non-parametric prediction limits.
Confidence interval used during calculations = 99%
ND<40 The nondetected value for antimony for MW-4B on 3/10/2009 was <40 µg/L. All other antimony nondetect values <2.5 or <0.5 for this well.
Outlier High concentrations lacking correlated turbidity measurements and may potentially be statistical outliers.
<Value is less than detection limit
B Data flagged due to detection in field blank
NS Not Sampled
*
**
Assessment monitoring well data compared to inter-well parametric prediction
limit due to higher statistical power (1-β) in relation to non-parametric and poisson
Inter-well non-parametric and poisson prediction limits will be used (dependent on
distribution and % NDs) when a sufficient number of samples have been collected

Velocity is based on the Seepage Velocity Equation where velocity equals (K x i) / n

Hydraulic Conductivity (K)
Hydraulic Gradient (i)
Porosity (n) 20 to 50 percent

Notes:
1. The hydraulic conductivity, K, is calculated from the geometric mean slug tests. See Table 6-7.
2. Soil type based on field lithologic description of soil borings.
3. Porosity is assumed based on Table 3.4 Porosity Ranges for Sediments from Fetter (2001). Applied
hydrogeology (Vol. 3, No. 3). Upper Saddle River: Prentice hall.
