CITY OF ROSEVILLE 2001 WATER QUALITY DATA | Unnamed: 1 | Unnamed: 2 | Unnamed: 3 | Unnamed: 4 | Unnamed: 5 | Unnamed: 6 | Unnamed: 7 | Unnamed: 8
The presence of these contaminants in the water does not necessarily indicate that the water poses a health risk.
Unless otherwise noted, the data presented in these tables is from testing done January 1 - December 31, 2001.
The State requires the City of Roseville to monitor for certain contaminants less than once per year because the
concentrations of these contaminants is not expected to vary significantly from year to year.
Microbiological Primary Drinking Water Standards
 |  |  | PHG or | Roseville Water |  | Sample |  | Typical Source of
 | Units | MCL | (MCLG) | Highest | Lowest | Date | Violation | Contamination
Turbidity* | ntu | TT = 5 ntu | ns | 0.16 |  | 2001-06-01 00:00:00 | *NO* | Soil runoff
 |  | TT = samples
 |  | less than 0.5 ntu | ns |  | 1 | 2001 | *NO* | Soil runoff
*For turbidity the highest single measurement and the lowest monthly percentage of samples meeting the turbidity
limits are specified. Turbidity is a measurement of the clarity of the water.  Turbidity, of itself, may not be harmful
in drinking water, but too much suspended material can shield organisms from the disinfecting qualities of chlorine.
