MINERAL ANALYSIS REPORT - WATER WORKS PARK

CITY OF DETROIT

2007

Legend

MCL: Maximum Contaminant Level

Sec. Std.: Secondary Standard

NTU: Nephelometric Turbidity Unit

mg/L: Milligram Per Liter

MDL: Method Detection Limit

<: Less than

EF: Equipment Failure

IV: Invalid Sample

T= Plant tap

R = Raw water

Notes:
(1) Turbidity must not exceed 0.3 NTU in 95% of daily samples in any month
(2) EPA Guidance Level
(3) As Calcium Carbonate
mg/L is equivalent to part per million (ppm)
(4) By Titration
(5) Tap Water Hardness in Grains per Gallon GPG
(6) Reported results are below the low calibration standard but above the instrument
Detection limit.
