Table 4: Summary of Monitoring Results for MW -4
Notes:
B = Estimated value, less than the practical quantitation limit for that analyte, but greater than the method detection limit
U = Result less than method detection limit for that analyte
H = Analysis exceeded method hold time. pH is a field test with an immediate hold time.
* Reanalysis preformed for analyte, reanalysis result reported.
Values in Bold exceeded benchmark levels
