CONSUMER CONFIDENCE REPORT
DEFINITIONS |
| NA |
Not
available or not determined. |
| ND |
Non-detected
or below detection limit; constituent is not present or detectable. |
| ppm
or mg/L |
Parts
per million: approximately one minute in two years. |
| ppb
or ug/L |
Parts
per billion: approximately one minute in 2000 years. |
| ppt
or nanograms/L |
Parts
per trillion: approximately one minute in 2 million years. |
| ppq
or picograms/L |
Parts
per quadrillion: approximately one minute in 2 billion years. |
| pCi/L |
Pico
curies per liter: is a measure of radioactivity in water. |
| MFL |
Million
fibers per liter: measure of the presence of asbestos fibers that are
longer than 1.0 micrometer. |
| NTU |
Nephelometric
Turbidity Units – measure of the clarity of water. Turbidity in above 5 NTU is just noticeable with the eye. |
| AL |
Regulatory
Action Level: the concentration of a contaminant, which if exceeded,
triggers treatment or other requirements which a water system must
follow. |
| MCL |
Maximum
Contaminant Level: The highest level of a contaminant that is allowed
in drinking water.
Primary MCLs are set as close to the PHGs (or MCLGs) as is
economically and technologically feasible.
Secondary MCLs are set to protect the odor, taste, and
appearance of drinking water. |
| MCLG |
Maximum
Contaminant Level Goal: The level of a contaminant in drinking water
below which there is no known or expected risk to health.
MCLGs are set by the U.S. Environmental Protection Agency. |
| PHG |
Public
Health Goals: the level of a contaminant in drinking water below which
there is no known or expected risk to health.
PHGs are set by the California Environmental Protection Agency. |
| PDWS |
Primary
Drinking Water Standards: MCL’s for contaminates that affect health
along with their monitoring and reporting requirements, and water
treatment requirements. |
| Range |
The
lowest and highest level of constituent testing during the period. |
