II. Purpose: All Community water systems must analyze for coliform bacteria to determine compliance with

Arizona Administrative Code, Department of Environmental Quality – Safe Drinking Water. The purpose of this plan is to identify specific bacteriological sample locations for each water source (e.g. well) and locations that are representative of the water quality throughout the distribution system. This plan also addresses the timing, frequency and rotation period for the collection of water samples in compliance with Arizona Administrative Code. This plan will be available for review and possible revision during all sanitary surveys conducted by the Arizona Department of Environmental Quality (ADEQ).

III. Rules Regarding Bacteriological Sampling for Medium Water Systems

A. Routine Samples - Per ADEQ, R18-4-202, which currently requires the collection of the following number of distribution system samples each month for Total Coliform analysis:

a. Systems serving from 8,501 to 12,900 persons (e.g. AZ07305):

Ten (10) distribution system samples at sites that are representative of water throughout the distribution system.

3 of 10 compliance locations, BEF collects are requirements (Youth Center, Child

Development Center) per Air Force Instruction.

b. Non-Transient, Non-Community Water Systems:

One (1) distribution system samples at sites that are representative of water throughout the distribution system.

B. Repeat Samples - Positive Total Coliform or E. coli Sample

a. Luke AFB Water System - If a sample is determined as positive for total-coliform, it must be further tested for E. Coli and a set of three repeat samples must be collected on the same day within 24 hours (This time begins from when you were notified by the lab of the positive result).

The below table identifies site locations for resampling.

Original Location

Upstream tap w/in 5 service connections

Downstream tap w/in 5 service connections

All supplying active wells

(pre-treatment)

1 1 1 multiple

Total-Coliform Rule (TCR) – The re-sampling must be performed at the site where the original sample tested positive, and also two alternate locations five points upstream and downstream of the original site. If resample results come back negative, from original sampling point no further sampling is necessary. If resample results are positive for total coliform, CE Utilities will be contacted. Notification procedures must be followed; residents of housing/building where positive occurred will be notified.

Ground Water Rule (GWR) - Triggered source water monitoring is required after a total-coliform positive sample is collected from the distribution system in compliance with the TCR. Samples must be collected within 24 hours of notification, at least one sample from each ground water source (Wells) in use at the time the total coliform-positive routine sample was collected. The triggered source water samples must be analyzed for the presence of a State-approved fecal indicator (E. Coli). A positive fecal indicator GWR results is an Acute Violation requiring Public Notice. Contact ADEQ immediately at (602) 771-4560 or 1(800) 234-5677.

Repeat Sampling Locations - If a sample is taken at the beginning or at one service connection away from the beginning of the system is total-coliform positive, a repeat sample may not be required (can be waived by ADEQ, R18-4-202, H. d.) at an upstream site. If a sample taken at the end of the distribution system is total-coliform positive, then the original site plus 2 samples within 5 service connections upstream must be taken. In addition to these repeat samples, all active supplying well locations require sampling IAW the Groundwater Rule.

b. Gila Bend Water System- If a sample is determined positive for total-coliform, it must be tested for E. Coli and a set of at least three (3) repeat samples for each total coliform positive routine sample found (R18-4-202, H. 1.). Four (4) samples will be taken if a positive for total-coliform has been identified.

A public water system that collects fewer than five (5) routine samples per month and has one or more total coliform positive routine samples shall collect five (5) routine samples during the next month (R18-4-202, I.) (Not applicable Luke AFB has 10 routine samples per month)

c. Maximum Contaminant Levels (MCL) – If the MCL is exceeded, contact ADEQ at (602) 771-

4560/ 4561 immediately for further guidance concerning public notification of potential health risks. Notify 56 CES Utilities and Luke AFB Water Manager (56 CES/ CEOIU at DSN: 896- 6109). The following table presents MCL information gathered from the EPA quick reference guide for the TCR:

Samples collected MCL Non-Compliance

Less than 40 samples/month 1 sample is positive for total coliform bacteria

Any e. Coli positive repeat sample 1 positive repeat sample is an acute health risk (24 hr public notice)

Any total coliform positive sample following an E. coli positive routine sample

1 positive sample is an acute health risk (24 hr public notice)

d. Possible Health Risks – Confirmatory samples containing fecal coliforms or E. coli indicate the presence of contamination that could cause acute health problems. This may result in the ADEQ notice of violation.

*triggered source water sampling identified in EPA, Ground Water Rule, collect at least one ground water source sample from each source in use at the time the total coliform+ sample was collected.

Take during the 3rd.

year of the first 3-yr compliance period of each 9-year compliance cycle.

V. Chemical Sampling & Compliance Section

A. Confirmation Samples

Confirmation samples must be taken whenever a sample exceeds the MCL for nitrate or nitrite and/or if an unregulated contaminant is detected. Confirmation samples should be taken for other inorganic contaminants, organic contaminants, radionuclides, or secondary contaminants. For regulated contaminants, average the confirmation sample result with the first sample result, and use the average to determine compliance. Confirmation samples must be collected at the same sampling point as soon as possible (no later than two weeks) after the initial sample was taken.

B. Determinating Compliance with Sampling Requirements

Compliance with Arizona Administrative Code (AAC) Title 18, Chapter 4, is based on the analytical results obtained at each sampling point. If one sampling point violates the MCL, the system is in violation of the MCL. If more than one sample is collected during the year, compliance is determined by averaging all samples taken at each sampling point. If the annual average of any sampling point is exceeds the MCL, the system is out of compliance. Any sample result below the regulatory detection limit is calculated as zero in determining the running annual average.

Except for nitrate and nitrite, if sampling is conducted annually or less frequently, a sample result exceeding the MCL will not be considered in violation of the MCL until one year of quarterly sampling has been completed. For nitrate or nitrite, the system is immediately out-of-compliance if any sample result exceeds 50% of the MCL.

If an initial or a subsequent sample would cause the annual average to exceed the MCL, then the system is immediately out of compliance. If a system that is not in compliance with an MCL or MRDL, ADEQ must be notified as soon as possible (within 24 hours) of receiving the results and the public must be notified. Also notify 56 CES Utilities and Luke AFB Water Manager (56 CES/ CEOIU at DSN: 896-6109).

B. Content of Public Notices

* IMPORTANT: For Public Notices the rule specialist should be contacted for the violation template to be completed. The template includes the below information as well as up-to-date requirements.

Each notice must be conspicuous, contain only neccessary technical language, be printed in easily readable print and contain all of the following elements:

a. Description of the violation, exceedance, situation, or failure, including the contaminant(s) of concern, and (as applicable) the contaminant level(s);

b. When the violation, exceedance, situation, or failure occurred;

c. Potential adverse health effects resulting from the violation, exceedance, situation, or failure, including the applicable language on potential adverse health effects for those contaminants and disinfectants found in Appendix B to Subpart Q of 40 CFR 141, “Standard Health Effects Language for Public Notification,”

d. The population at risk, including subpopulations particularly vulnerable if exposed to the contaminant in their drinking water;

e. Whether boiled water or alternative sources of water should be used;

f. What action consumers should take, including when they should seek medical help;

g. What the system is doing to correct the violation, exceedance, situation, or failure;

h. When the system expects to return to compliance or resolve the violation, exceedance, situation, or failure;

i. Name, business address, and phone number of the water system owner, operator, or designee of the public water system as a source of additional information concerning the notice;

j. The following standard language to encourage the distribution of the public notice to all persons served: “Please share this information with all the other people who drink this water, especially those who may not have received this notice directly (for example, people in apartments, nursing homes, schools, and businesses). You can do this by posting this notice in a public place or distributing copies by hand or mail.”

For monitoring violations, the following standard language must be used: “We are required to monitor your drinking water for specific contaminants on a regular basis. Results of regular monitoring are an indicator of whether or not your drinking water meets health standards.

During [fill in compliance period], we did not monitor or test for [fill in contaminant(s)], and therefore cannot be sure of the quality of your drinking water during that time.”

C. Recission of Public Notices

The rescission notice must be distributed in the same manner to the same target audience as the initial public notice. Rescissions must include all of the following information:

a. Description and the date of the original notice;

b. Actions taken that resulted in the lifting of the notice;

c. Effective date of the rescission;

d. Name, business address, and phone number of the water system owner, operator, or designee of the public water system as a source of additional information concerning the rescission.

VII. Rules Regarding Compliance Monitoring for Copper and Lead

A. Initial and Routine Monitoring – 40 CFR 141, sections 141.80 -141.91 requires community water systems to conduct the following initial and routine monitoring for lead and copper:

All first-draw tap samples must be one liter in volume and have stood motionless in the plumbing system of each sampling site for at least six hours. First draw samples from residential housing must be collected from the cold water kitchen tap or a bathroom sink tap. First-draw samples from a nonresidential building must be collected at an interior tap from which water is typically drawn for consumption.

Each first draw tap sample must be taken from the same sampling site where previous samples were collected. If entry to a sampling site is prevented, the follow-up tap sample may be collected from another sampling site in its sampling pool as long as the new site meets the same targeting criteria, and is within reasonable proximity of the original site.

b. Sampling Requirements for Tap Water – Number of Samples and Monitoring Frequency

A pool of targeted sampling sites within distribution system for each water system must be identified that meets regulatory requirements, and is large enough to ensure that the correct number of samples for lead and copper tap samples are collected. The sampling sites must consist of buildings that contain copper pipes with lead solder installed after 1982 or contain lead pipes;

and/or are served by a lead service line. Sampling sites cannot include faucets that have a point of use or point of entry treatment devices that remove inorganic contaminants. Any water system whose distribution system contains lead service lines must draw 50% of the samples for each monitoring period from sites that contain lead pipes or copper pipes with lead solder and 50% of the samples from sites served by a lead service line. If the water system cannot identify enough sampling sites served by a lead service line, first draw samples must be collected from all sites being served by such lines.

A medium community water system is required to collect at least one (1) sample from 40 sampling sites for initial sampling. The number of sampling sites may be reduced to 20 after the lead and copper action levels are achieved for two consecutive six month monitoring periods.

Continued operation and monitoring. All systems optimizing corrosion control must maintain optimal corrosion control treatment, including WQPs at > minimum values or within ranges designated by ADEQ. Compliance is determined every six months, as specified under §141.87(d). System is out of compliance with the requirements of this paragraph for a six-month period if it has excursions for any State-specified parameter on more than nine days during the period. An excursion occurs whenever the daily value for one or more of the water quality parameters measured at a sampling location is below minimum value or outside range designated by ADEQ.

c. Sampling Requirements for Source Water and Water Quality Parameters

A water system that fails to meet the lead or copper action level on the basis of tap water samples must also concurrently collect lead and copper source water samples and source water and distribution system samples for water quality parameters (WQP). Monitoring requirements for WQP and source water are presented in figures 8 and 9.

VIII. Public Education and Notification Requirements for Lead and Copper Exceedance

A. Consumer Notice - A consumer notice of lead tap water monitoring results must be provided to persons served at the sites (taps) that are tested. If the lead action level (AL) is exceeded, a public education material must be delivered to affected consumers, and that tap water must be sampled by any customer who requests it. Public education materials are not required in the event of a copper action level exceedance.

B. Content of Public Education Materials - All of the following information (in the same order as listed below) must be included in printed materials. ADEQ may require approval of the content of written public materials prior to delivery.

a. “IMPORTANT INFORMATION ABOUT LEAD IN YOUR DRINKING WATER. [INSERT

NAME OF WATER SYSTEM] found elevated levels of lead in drinking water in some homes/buildings. Lead can cause serious health problems, especially for pregnant women and young children. Please read this information closely to see what you can do to reduce lead in your drinking water.”

b. “Health effects of lead. Lead can cause serious health problems if too much enters your body from drinking water or other sources. It can cause damage to the brain and kidneys, and can interfere with the production of red blood cells that carry oxygen to all parts of your body. The greatest risk of lead exposure is to infants, young children, and pregnant women. Scientists have linked the effects of lead on the brain with lowered IQ in children. Adults with kidney problems and high blood pressure can be affected by low levels of lead more than healthy adults. Lead is stored in the bones, and it can be released later in life. During pregnancy, the child receives lead from the mother's bones, which may affect brain development.

c. Possible sources of lead in drinking water and how it enters drinking water, including information on home/building plumbing materials and service lines that may contain lead

d. Other important sources of lead exposure in addition to drinking water (e.g., paint).

e. Steps consumers can take to reduce their exposure to lead in drinking water such as running the water to flush out the lead.

f. Concerns with using hot water from the tap and a specific caution against the use of hot water for preparing baby formula.

g. A statement that boiling water does not reduce lead levels.

h. Other options consumers can take to reduce exposure to lead in drinking water, such as alternative sources or treatment of water.

i. A suggestion that parents have their child's blood tested for lead.

j. Why lead levels are elevated in the system's drinking water (if known) and what the water system is doing to reduce the lead levels in homes/buildings in this area.

k. “For more information, call us at [INSERT YOUR NUMBER] [(IF APPLICABLE), or visit our Web

FA8903-16-R-0009

site at [INSERT YOUR WEB SITE HERE]]. For more information on reducing lead exposure around your home/building and the health effects of lead, visit EPA's Web site at http://www.epa.gov/lead or contact your health care provider.”

A lead public education report for the PWS must be completed and submitted to ADEQ for systems that exceed the lead action level within ten days after the end of each period that the system is required to perform public education tasks per 141.85.

C. Delivery of Public Education Materials - Public education materials must be delivered within 60 days of a lead exceedance, continue every six months for PSAs and annually for all other forms of delivery for as long as the lead exceedance continues. Delivery can be discontinued once sampling results indicate compliance with the lead action level but must resume if there is a subsequent exceedance. Public education materials must meet all of the following delivery criteria:

a. Informational posters on lead in drinking water must be posted in a public place or common area in each of the buildings served by the system.

b. Informational pamphlets on lead in drinking water must be delivered to each person served by the water system. ADEQ may approve electronic transmission in lieu of printed materials if it achieves at least the same coverage.

These tasks must be repeated at least annually at least once during the time that the system exceeds the lead action level. A water system may discontinue delivery of public education materials if the system has met the lead action level during the most recent six-month monitoring period.

IX. Sanitary Survey

A safe and reliable drinking water supply is essential to the health and well-being of our Air Force personnel and to sustain the many mission-critical operations that depend on it. Large quantities of potable water are required on a continuous basis for drinking, firefighting, decontamination, personal hygiene, sanitation, industrial operations, and other needs. These requirements can be met only if our water systems are properly designed, operated, maintained, and monitored. A sanitary survey periodically reviews these aspects in accordance with Safe Drinking Water Act (SDWA) regulations and DoD/Air Force directives. A sanitary survey is a proactive public health measure designed to identify and correct deficiencies before they can lead to contamination or disruption of the public water supply.

A sanitary survey examines and evaluates the adequacy of eight specific critical elements associated with water systems, as identified by the EPA:

� Source (Protection, Physical Components and Condition);

� Treatment;

� Distribution;

� Finished Water Storage;

� Pumps/Pump Facilities and Controls;

� Monitoring/Reporting/Data Verification;

� Water System Management/Operations; and, FA8903-16-R-0009

� Operator Compliance with State Requirements.

A sanitary survey identifies deficiencies associated with water safety and survivability, assesses the risks they pose, identifies practical control recommendations, and enables compliance with applicable regulatory requirements. A sanitary survey does not assess security-related deficiencies associated with water systems and supplies; this is the function of a Water Vulnerability Assessment (WVA). However, due to a number of overlapping factors, efficiencies can be realized when the sanitary survey and WVA are conducted in conjunction with each other.

AFI 48-144 states that the Bioenvironmental (BE) will ensure a sanitary survey is performed to satisfy the requirements of applicable regulations and standards. The BE is also responsible for recommending measures to be taken to maintain the sanitary quality of the base drinking water system. Currently, ADEQ funds and conducts the required sanitary survey.

Deficiencies found during the sanitary survey requiring infrastructure repair, redesign, or construction will be forwarded to the Base Civil Engineer (BCE) with recommendations for corrective action.

Water Source Community System Non-Community System Ground Water 3 years** 5 years *Community systems that have outstanding performance (as determined by the state) may have sanitary surveys conducted every five years.

** Community systems that have outstanding performance (as determined by the state) or treat to 4-log (99.99%) inactivation of viruses may have sanitary surveys conducted every five years.

X. Aircraft Watering Points Sampling

Aircraft Watering Point (AWP) sanitary surveys shall be conducted IAW AFI 48-144, “Safe Drinking Water Surveillance Program” and the Drinking Water Surveillance Technical Guide, published April 2011.

An AWP includes all of the equipment used to transfer potable water for human consumption to an aircraft. It does not include any part of the base distribution system or the aircraft’s internal water storage and dispensing system. It may include water trucks; hoses and faucets not permanently plumbed to the distribution system; and jugs, cans, and other containers that deliver potable water to aircraft.

Luke AFB does not have Aircraft Water Points.

XI. Consumer Confidence Report

The Consumer Confidence Report (CCR) Rule is an effort to improve the communication between the purveyor and the consumer, or public. The CCR Rule was promulgated on 19 Aug 98 (63 FR 44511) and is codified in Subpart O of 40 CFR 141. The Public Notification Rule revises timing and distribution requirements for public notices, expands the lists of violations and situations requiring immediate notification, simplifies mandatory health effects and monitoring violations language, consolidates public notification requirements, increases primacy agency flexibility, and amends the CCR Rule to conform

FA8903-16-R-0009

with these changes. The CCR Rule applies to all Community Water Systems (CWSs) and provides material to consumers to assist in making risk based decisions pertaining to their drinking water supply. It requires purveyors to prepare and distribute an annual water quality report summarizing information on the drinking water system and providing educational information.

The CCR is due to the base general public no later than 1 Jul of each year to be in compliance with the State regulator. The CCR is based on calendar-year data from the previous year. For example, all data from Jan-Dec 2012 must be included in the 2012 CCR, which is due to customers by 1 Jul 2013. Saying that, start compiling the information needed for the CCR early in the calendar year, to avoid possibly being late. At Luke, the CCR is prepared and routed for review NLT May of each year.

All CCRs must include the following eight basic items, at a minimum:

1. Required Information about the Water System (Name/phone number of contact person;

information on public participation opportunities; information for non-English speaking populations, if applicable)

2. Source(s) of Water (Type, name, and general location of water sources; availability of source water assessment; information on significant sources of contamination, if available)

3. Definitions (specific language) (MCL; MCLG; others as needed (i.e., variances, exemptions, Treatment Technique (TT), Action Level (AL), MRDL, and MRDLG)

4. Reported Levels of Detected Contaminants (Table summarizing data on detected regulated & unregulated contaminants; known or likely source of each detected contaminant; health effects language and explanation for any violations

5. Information on Monitoring for Cryptosporidium, Radon, and Other Contaminants (Warning for vulnerable populations about Cryptosporidium, if detected; explanation of radon and its presence in the finished water, if detected; explanation of unregulated contaminants and their presence in drinking water, if detected)

6. Compliance with Other Drinking Water Regulations (Explanation of violations, potential health effects and steps taken to correct the violations; special notices for GWR)

7. Variances and Exemptions (Explanation of variance/exemption, if applicable)

8. Required Educational Information (specific language) (Explanation regarding contaminants that may reasonably be expected to be found in drinking water, including bottled water; information to customers that some people may be more vulnerable to contaminants in drinking water; explanation of contaminants and their presence in drinking water, if detected; informational statements on arsenic and nitrate, if necessary, and lead, always required)

XII. Swimming Pool Inspection

A. Pool season usually begins in May at Luke AFB. Contact Pool Manager from Services (56 FSS/SVR) around 1 May to find out projected season opening date. Pre-season inspections must be accomplished within 72 hrs of pool opening. The following are steps to accomplish a pre-season pool inspection.

1. Review AFI 48-114 for guidance regarding Bioenvironmental Engineering Flight (BEF) responsibilities.

2.11.5. Bioenvironmental Engineering (BE).

Conduct inspection IAW AFI 48-114 Attachment 5 or Attachment 6 of this document.

3. Measure pH and disinfectant residual levels (FAC). Compare results to the lifeguard’s readings. Enter results into Water Log book.

4. Write MFR swimming pool inspection letter and forward to 56 FSS/SVR and 56 CE/CEOIU.

Letter should include: who conducted the inspection, date, and summary of findings, as necessary.

5. Letters are saved to Swimming Pool (click on the hyperlink for location).

B. Emergency* Swimming Pool Inspection Procedures: If you are notified of an incident, such as feces, blood, or vomit in the pool: Follow the requirements listed in AFI 48-114 Attachment 6. You

FA8903-16-R-0009

may also reference the CDC’s recommendations at their website for Healthy Swimming:

http://www.cdc.gov/healthywater/swimming/pools/vomit‐blood‐contamination.html. Below is an abbreviated version of the contact time required for proper disinfection.

1. What is recommended when there is a vomit or blood spill in a swimming pool?

- These germs do not survive long when diluted into properly chlorinated pool water. There is no public health reason to recommend closing the pool after a blood spill. However, some pool staff choose to do so temporarily to satisfy patrons.

2. What is recommended when there is a formed stool in a swimming pool?

-remove the stool with a net or a bucket ASAP and follow disinfection removal times… -E. coli (bacteria) – less than 1 minute -Hepatitis A (virus) – approximately 16 minutes
