MEMORANDUM FOR MAXWELL COMMANDERS AND COMMANDANTS

FROM: 42 ABW/CV

SUBJECT: Annual Consumer Confidence Report on Drinking Water

1. Each year in accordance with AFI 48-144, Safe Drinking Water Surveillance Program, all Air Force

drinking water systems are required to send out a annual Consumer Confidence Report (CCR)

highlighting the previous calendar year’s sample results and water treatment processes. As in the past,

our water continues to be healthy and exceed all Safe Drinking Water Act requirements.

2. In accordance with AFI 48-144, installations that receive a CCR from a local water supplier will

provide the CCR to the base population. The Maxwell-Gunter Community receives its water from the

Montgomery Water Works and Sanitary Sewer Board (MWWSSB) and their CCR is attached for your

review. Please take the time to review the MWWSSB CCR and feel free to contact our Bioenvironmental

Engineering (BE) Flight if you have any questions. Additionally, an e-copy of the CCR is available for

all base residents to review/download at the Maxwell-Gunter’s homepage (http://www.maxwell.af.mil/)

by following the “Water Quality Report” link on the right hand side.

3. In addition to the sampling performed by MWWSSB, our BE Flight collected an additional 192

drinking water samples in calendar year 2009, analyzing for pH, chlorine, fluoride and total coliforms

(i.e., bacteriological contaminants). Every sample collected and analyzed by our B E F light met or

exceeded Safe Drinking Water Act requirements, and indicates the water supplied to the Maxwell-

Gunter community is safe for consumption.

4. We also receive water from Walnut Hill Authority for Lake Martin Recreational area, Central Elmore

Water Authority (CEW&SA) for Vigiliant Warrior site at Lake Jordan, and Okaloosa County Water

Authority for Mid-Bay Shores Recreational site. Those reports may also be reviewed/downloaded by

following the “Water Quality Report” link at http://www.maxwell.af.mil/.

5. Rest assured the water provided to the Maxwell-Gunter Community is of the highest quality.

Questions regarding any drinking water issues you may have may be addressed to Mr. Thomas Rucker,

42 ADOS/SGPB, at 953-5848 or thomas.rucker@maxwell.af.mil.

2009 Water Quality Report


Annual Drinking Water Quality Report

Walnut Hill Water Authority

January-December 2009

Is my water safe?

Last year, as in years past, your tap water met all U.S. Environmental Protection Agency (USEPA) and the Alabama Department of Environmental

Management (ADEM) drinking water health standards. Your local water officials vigilantly safeguard its water supplies and once again we are proud

to report that our system has not violated a maximum contaminant level or any other water quality standards. We're pleased to present to you this

year's Annual Drinking Water Quality Report. This report is designed to inform you about the quality water and services we deliver to you every day.

Our constant goal is to provide you with a safe and dependable supply of drinking water. We want you to understand the efforts we make to

continually improve the water treatment process and protect our water resources. We are committed to ensuring the quality of your water. Our source

water comes from the Adams Filter Plant, which is located in Alex City. The water we supply to our customers requires no specialized treatment.

However, Chlorine is added to the water as disinfectant and the required residual is maintained to protect your drinking water from any possible

outside contaminants.

The Walnut Hill Water Authority routinely completes a water storage facility inspection plan, and utilizes a Bacteriological Monitoring Plan and a

Cross Connection Policy is in place to insure good safe drinking water for our customers. Alexander City has completed a Source Water Assessment

Plan, which is available at their office for review. This report provides information about potential sources of contamination and is set up to help

protect our source.

We want our valued customers to be informed about their water utility. If you want to learn more, please attend any of our regularly scheduled Board

meetings. They are held on the 3rd Monday of the month at the Walnut Hill Water Authority office that is located at 7791 Hwy 50 and begin at 6:30

p.m.

The members of the Board of Directors are: Ben Sands, Chairman, David Moore, E rnie Barnes

Important Drinking Water Definitions:

Action Level (AL) - The concentration of a contaminant that triggers treatment or other requirements that a water system shall follow.

Maximum Contaminant Level (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 (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 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.

Millirems per year (mrem/yr) - Measure of radiation absorbed by the body.

Nephelometric Turbidity Unit (NTU) - Nephelometric turbidity unit is a measure of the clarity of water. Turbidity in excess of 5 NTU is just

noticeable to the average person.

Non-Detects (ND) - Laboratory analysis indicates that the constituent is not present.

Parts per million (ppm) or Milligrams per liter (mg/L) - One part per million corresponds to one minute in two years or a single penny in $10,000.

Parts per billion (ppb) or Micrograms per liter (µg/L) - One part per billion corresponds to one minute in 2,000 years, or a single penny in

$10,000,000.

Parts per trillion (ppt) or Nanograms per liter (ng/L) - One part per trillion corresponds to one minute in 2,000,000 years, or a single penny in

$10,000,000,000.

Parts per quadrillion (ppq) or Picograms per liter (pg/L) - One part per quadrillion corresponds to one minute in 2,000,000,000 years or one penny

in $10,000,000,000,000.

Picocuries per liter (pCi/L) - Picocuries per liter is a measure of the radioactivity in water.

Treatment Technique (TT) - A required process intended to reduce the level of a contaminant in drinking water.

Threshold Odor Number (T.O.N.) - The greatest dilution of a sample with odor-free water that still yields a just-detectable odor.

Variances & Exemptions - ADEM or EPA permission not to meet an MCL or a treatment technique under certain conditions.

Explanation of reasons for variance/exemptions

Based on a study conducted by ADEM with the approval of the EPA a statewide waiver for the monitoring of asbestos and dioxin was issued. Thus

monitoring for these contaminants was not required.

The Walnut Hill Water Authority routinely monitors for contaminants in your drinking water according to Federal and State laws. Unless otherwise

noted, the data presented in the following tables show the results of our monitoring period of January 1 st to December 31 st , 2009.

All drinking water, including bottled drinking water, may be reasonably expected to contain at least small amounts of some contaminants. It's

important to remember that the presence of these contaminants does not necessarily pose a health risk. The EPA or ADEM requires us to monitor for

certain contaminants less than once per year because the concentrations of these contaminants do not change frequently. The table below lists all of

the drinking water contaminants that we detected.

If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is

primarily from materials and components associated with service lines and home plumbing. Walnut Hill Water Authority is responsible for

providing high quality drinking water, but cannot control the variety of materials used in plumbing components. When your water has been sitting for

several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking or

cooking. If you are concerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing

methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline or at http://www.epa.gov/safewater/lead.

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 radioactive material, and it can pick up substances

resulting from the presence of animals or from human activities.

As you can see by the tables, our system had no monitoring violations of allowable limits of contaminants in drinking water. We’re proud that your

drinking water meets or exceeds all Federal and State requirements. We have learned through our monitoring and testing that some contaminants

have been detected. The EPA has determined that your water IS SAFE at these levels. MCL’s are set at very stringent levels. To understand the

possible health effects described for many regulated contaminants, a person would have to drink 2 liters of water every day at the MCL level for a

lifetime to have a one-in-a-million chance of having the described health effect.

Total Coliform: The Total Coliform Rule requires water systems to meet a stricter limit for coliform bacteria. Coliform bacteria are usually

harmless, but their presence in water can be an indication of disease-causing bacteria. When coliform bacteria are found, special follow-up tests are

done to determine if harmful bacteria are present in the water supply. If this limit is exceeded, the water supplier must notify the public by newspaper,

television or radio. To comply with the stricter regulation, we have increased the average amount of chlorine in the distribution system.

Some people may be more vulnerable to contaminants in drinking water than the general population. People who are immuno-compromised such as

cancer patients undergoing chemotherapy, organ transplant recipients, HIV/AIDS positive or other immune system disorders, some elderly, and

infants can be particularly at risk from infections. People at risk should seek advice about drinking water from their health care providers. EPA

(Environmental Protection Agency)/CDC (Center of Disease Control) guidelines on appropriate means to lessen the risk of infection by

Cryptosporidium and other microbiological contaminants are available from the Safe Drinking Water Hotline. All Drinking water, including bottled


drinking water, may reasonably be expected to contain at least small amounts of some contaminants. More information about contaminants and

potential health effects can be obtained by calling the Environmental Protection Agency’s Safe Drinking Water Hotline (800-426-4791).

Thank you for allowing us to continue providing your family with clean, quality water this year. In order to maintain a safe and dependable water supply we

sometimes need to make improvements that will benefit all of our customers. These improvements are sometimes reflected as rate structure adjustments. Thank

you for understanding.

We at the Walnut Hill Water Authority work around the clock to provide top quality water to every tap. We ask that all our customers help us protect our water

sources, which are the heart of our community, our way of life and our children’s future.

2009 Water Quality Report


2009

Annual Drinking Water Quality Report

Of the Okaloosa County

Water and Sewer System

We are pleased to present to you this year's Annual Water Quality Report. This report is designed

to inform you about the quality water and services we deliver to you every day. Our constant goal

is to provide you with a safe and dependable supply of drinking water. We want you to

understand the efforts we make to continually improve the water treatment process and protect

our water resources. We are committed to ensuring the quality of your water. Our water source is

ground water drawn from the Floridan Aquifer. Due to the excellent quality of our water the only

treatment process required at most systems is disinfection using chlorine at each well.

The Okaloosa County Water and Sewer System routinely monitors for contaminants in your

drinking water according to Federal and State laws, rules, and regulations. Except where

indicated otherwise, this report is based on the results of our monitoring for the period of January

I to December 31,2009. The state has reduced monitoring requirements for certain contaminants

to less often than once per year because the concentrations of these contaminants do not change

frequently. Some of our data, though representative, is more than one year old. All drinking

water, including bottled drinking water, may be reasonably expected to contain at least small

amounts of some contaminants. It's important to remember that the presence of these

contaminants does not necessarily pose a health risk.

In 2009 the Department of Environmental Protection performed a Source Water Assessment

(S WA) on our systems. These assessments were conducted to provide information about any

potential sources of contamination in the vicinity of our wells. There are 16 potential sources of

contamination identified for the Main system (PWS 1460506) with low to moderate susceptibility

levels. In the Bluewater/Raintree system (PWS 1460775) there was no potential sources of

contamination. The County West system (PWS 1460597) has 2 potential source of contamination

with moderate susceptibility levels. The SWA for the Mid County system (PWS 1464044)

revealed I potential source of contamination with a moderate susceptibility level. The assessment

results are available on the FDEP Source Water Assessment and Protection web site:

www.dep.state.tl.us/swapp or they can be obtained from OCWS at 651-7133.

The sources of drinking water (both tap 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 storm water 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 storm water 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 storm water runoff, and septic systems.

(E) Radioactive contaminants, which can be naturally occurring or be the result of oil and gas

production and mining activities.

In this table you will find many terms and abbreviations you might not be familiar with. To help

you better understand these terms we've provided the following definitions:

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.

Not Applicable - (N/A)

"ND" means not detected and indicates that the substance was not found by laboratory analysis.

Parts per million (ppm) or Milligrams per liter (mg/I) - one part by weight of analyte to 1

million parts by weight of the water sample.

Parts per billion (ppb) or Micrograms

by weight of the water sample.

per liter - one part by weight of analyte to 1 billion parts

Picocuries per liter (pCi/L) - Picocuries per liter is a measure of the radioactivity in water.

Action Level (AL) - the concentration of a contaminant which, if exceeded, triggers treatment or

other requirements which a water system must follow.

Maximum Contaminant Level - The "Maximum Allowed" (MCL) is 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 Containment Level Goal - The "Goal" (MCLG) is 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 or MRDL: The highest level of a disinfectant allowed in

drinking water. There is convincing evidence that addition of a disinfectant is necessary for

control of microbial contaminants.

Maximum residual disinfectant level goal or 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.

While your drinking water meets USEPA's standard for arsenic, the Mid-County and Main

systems do contain low levels of arsenic. USEPA's standard balances the current understanding

of arsenic's possible health effects against the costs of removing arsenic from drinking water.

USEPA continues to research the health effects of low levels of arsenic, which is a mineral

known to cause cancer in humans at high concentrations and is linked to other health effects such

as skin damage and circulatory problems.

In order to ensure that tap water is safe to drink, EPA prescribes regulations which limit the

amount of certain contaminates in water provided by public water systems. FDA regulations

establish limits for contaminants in bottled water which must provide the same protection for

public health. All drinking water, including bottled water, may reasonably be expected to contain

at least small amounts of some contaminants. The presence of contaminants does not necessarily

indicate that the water poses a health risk. More information about contaminants and potential

health effects can be obtained by calling the Environmental Protection Agency's Safe Drinking

Water Hotline at 1-800-426-4791.

If present, elevated levels of lead can cause serious health problems, especially for pregnant

women and young children. Lead in drinking water is primarily from materials and components

associated with service lines and home plumbing. Okaloosa County Water and Sewer is

responsible for providing high quality drinking water, but cannot control the variety of materials

used in plumbing components. When your water has been sitting for several hours, you can

minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before

using water for drinking or cooking. If you are concerned about lead in your water, you may

wish to have your water tested. Information on lead in drinking water, testing methods, and steps

you can take to minimize exposure is available from the Safe Drinking Water Hotline or at

http://www.epa.gov/safewater/lead.

MCLs are set at very stringent levels. To understand the possible health effects described for

many regulated constituents, a person would have to drink 2 liters of water every day at the MCL

level for a lifetime to have a one-in-a-million chance of having the described health effect.

Some people may be more vulnerable to contaminants in drinking water than the general

population. Immuno-compromised persons such as persons with cancer undergoing

chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or

other immune system disorders, some elderly, and infants can be particularly at risk from

infections. These people should seek advice about drinking water from their health care

providers. EPAlCDC guidelines on appropriate means to lessen the risk of infection by

cryptosporidium and other microbiological contaminates are available from the Safe

Drinking Water Hotline (800-426-4791).
