Water-Year Summary for Site 02335880
Data for parameter code 63680 (turbidity) were collected using a probe with the following specifications: turbidity, water, monochrome near infra-red LED light, 780-900 nm, detection angle 90 +/-2.5 degrees, FNU (Formazin Nephelometric Units). Prior to October 1, 2004, turbidity data were published using parameter code 00076: turbidity, water, unfiltered, NTU (Nephelometric Turbidity Units).
Discrete sample turbidity measurements are taken in the lab using a Hach 2100 and are reported in Nephelometric Turbidity Ratio Units, (NTRU). Calibration is performed on the meter using Hach supplied and approved standards. USGS Georgia District policy has stated that turbidity will have a lower reporting threshold of 2 NTRU and an upper limit of 1,100 NTRU. The precision and accuracy associated with turbidity has required the overall record to be rated fair.
