CITY COMMISSION MEETING
STAFF REPORT
AGENDA ITEM: Annual Water Quality Report
SUBMITTED BY: Donna Kaluzniak, Utility Director
DATE: May 31, 2012
BACKGROUND: A copy of the 2011 Water Quality Report for the City of Atlantic Beach is
provided for the City Commission's review. The Florida Department of Environmental
Protection requires annual water quality reports be mailed to all customers by the first of July
every year.
The City is required to test for over 80 drinking water contaminants, but only those detected
during analysis are included in the report. As shown, detected values were within the levels
allowed and we had no violations of water quality limits.
BUDGET: A total of $600 is budgeted in the Water Fund for printing the reports, under account
numbers 400 - 5502 -533 -4700.
RECOMMENDATION: No action necessary. The report is provided for information only.

AGENDA ITEM # 4C
JUNE 11, 2012
In the table you will find many terms and abbreviations you might not be familiar with. To help you
better understand these terms, we have provided the following definitions:
Action Level (AL) — The concentration of a contaminant which, if exceeded, triggers treatment or other
requirements which a water system must follow.
Initial Distribution System Evaluation (IDSE )—An important part of the Stage 2 Disinfection
Byproducts Rule (DBPR). The IDSE is a one -time study conducted by water systems to identify
distribution system locations with high concentrations of trihalomethanes (THMs) and haloacetic acids
(HAAs). Water systems will use results from the IDSE, in conjunction with their Stage 1 DBPR
compliance monitoring data, to select compliance monitoring locations for the Stage 2 DBPR.
Maximum Contaminant Level or MCL — The highest level of a contaminant that is allowed in
drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment
technology.
Maximum Contaminant Level Goal or MCLG — The level of a contaminant in drinking water below
which there is no known or expected risk to health. MCLGs allow for a margin of safety.
Maximum Residual Disinfectant Level (MRDL) – The highest level of a disinfectant allowed in
drinking water. There is a convincing evidence that addition of a disinfectant is necessary for control of
microbial contaminants.
Maximum Residual Disinfectant Level Goal (MRDLG) – The level of a drinking water disinfectant
below which there is no known or expected risk to health. MRDLGs do not reflect the benefits of the use
of disinfectants to control microbial contaminants.
Non - Detects (ND) — Means not detected and indicates that the substance was not found by laboratory
analysis.
Not Applicable (N /A) – The information does not apply in this category or for this contaminant.
Parts per billion (ppb) or Micrograms per liter (ug/L) – One part by weight of analyte to one billion
parts by weight of the water sample.
Parts per million (ppm) or Milligrams per liter (mg/L) – One part by weight of analyte to one million
parts by weight of the water sample.
Picocuries per liter (pCi/1) – Measure of the radioactivity in water.
The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds,
reservoirs, springs and wells. As water travels over the surface of the land or through the ground, it
dissolves naturally - occurring minerals and, in some cases, radioactive material, and can pick up
substances resulting from the presence of animals or from human activity. Contaminants that may be
present in source water include:
(A) Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment
plants, septic systems, agricultural livestock operations and wildlife.
(B) Inorganic contaminants, such as salts and metals, which can be naturally- occurring or result from
urban stormwater runoff, industrial or domestic wastewater discharges, oil and gas production, mining or
farming.
(C) Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban
stormwater runoff, and residential uses.
(D) Organic chemical contaminants, including synthetic and volatile organic chemicals, which are by-
products of industrial processes and petroleum production, and can also come from gas stations, urban
stormwater runoff and septic systems.
(E) Radioactive contaminants, which can be naturally occurring or be the result of oil and gas production
and mining activities.

STAGE 1 DISINFECTANTS AND DISINFECTION BY- PRODUCTS
For broniare, chloramines, or chlorine, the level detected is the the highest running annual average (PAA), computer) quarterly,
of monthly averages of all samples collected. For haloacetic acids or 7 11 M, the level detected is the highest RAA, computed quarterly,
of quarterly averages of all samples collected if the system is monitoring quarterly or is the average of all samples taken during the
year if the system monitor's less frequently than quarterly. Range of Results is the range of individual sample results (lowest to
highest) for all monitoring locations, including Initial distribution System Evaluation (i0SE) results as well as Stage 1 compliance
results,
