(A) = Erosion of natural deposits.
Note: The EPA requires monitoring of over 80 drinking water contaminants. Those listed
above are the only contaminants detected in your drinking water. For a complete list of testing
results, showing all tests performed, contact our Water Department
at (563) 262-3360.
Unregulated Contaminants are those for which EPA has not established drinking water standards. The purpose of unregulated contaminant monitoring is to assist EPA in determining the occurrence of unregulated contaminants in drinking water and whether future regulation is warranted.
Definitions
Action
Level - The concentration of a contaminant that, if exceeded,
triggers a treatment or other requirement that a water system
must follow.
Inorganic
Chemicals - Chemical substances of mineral origin.
Maximum
Contaminant Level (MCL) - The highest level of a contaminant
allowed in drinking water. MCLs are set as close to the MCLGs
as feasible using the best available treatment technology.
Maximum
Contaminant Level Goal (MCLG) - The level of a contaminant
in drinking water below which there is no known or expected
risk to health.
Microbiological
Contaminants - Very small organisms, such as bacteria,
algae, plankton, and fungi.
N/A
- Not applicable
N/D
- Not detected at testing limit.
NTU
- Nephelometric Turbidity Units.
Organic
Contaminants - Naturally occurring or synthetic substances
containing mainly carbon, hydrogen, nitrogen and oxygen. This
includes more pesticides and industrial chemicals.
PCi/l
- Pico curies per liter
ppb
- Parts of contaminant per billion parts of water. One
part per billion (ppb) is equivalent to a single penny in
ten million dollars.
ppm-
Parts of contaminant per million parts of water. One part
per million (ppm) is equivalent to a single penny in ten million
dollars.
mg/l
- micrograms per liter (parts of contaminant per billion parts
water). One part per billion (ppb) is equivalent to a single
penny in ten thousand dollars.
µg/l
- milligrams per liter (parts of contaminant per million parts
of water). One part per million (ppm) is equivalent to a single
penny in ten thousand dollars.
Radionuclides
- Contaminants giving off ionizing radiation.
TOC
- Total organic carbon in untreated water.
Treatment
Technique (TT) - A reguired process intended to reduce
the level of a contaminant in drinking water. |
