SCOPE OF WORK

Summary of Work:

The Bureau of Land Management (BLM), Arizona State Office (ASO), in support of the Yuma Field Office (YFO), is requesting proposals from qualified companies to provide Certified System Operator service and supply for all treatment chemicals, testing media, and treatment system maintenance materials. Applicants shall be licensed as a Certified Water System Operator in Arizona and California, and able to provide chemical treatment for delivery of potable water, laboratory testing, treatment system maintenance, and other related technical services such as preparing and filing reports and producing reporting system input as related to the delivery of potable water for public consumption and use. The Imperial System generates up 600,000 gallons per year and the existing La Posa South system generates up 400,000 gallons per year the additional system located at La Posa Tyson will generate an additional 600,000 gallons annually. This system is not yet online or in production

ASO intends to award a contract with a base year and 4 option years, up to 5 years total. An itemized proposal shall include the furnishing of all labor categories, equipment, materials, tools, supervision, and all other items incidental to and required to provide testing for safe drinking water, laboratory testing with reports, and related technical services that comply with the County of Imperial, California, La Paz County, Arizona, and ADEQ.

YFO is requesting service at the three recreation sites. La Posa South and La Posa Tyson Long Term Visitor Area (LTVA) located in Quartzite, AZ (See appendix A: La Posa Drinking Water Monitoring Plan) with 2 seperate water sources and 10 sample sites (see site map) and Imperial Dam LTVA, (See Appendix B South Mesa Drinking Water Monitoring Plan) located in Winterhaven, CA north of Yuma, AZ on the California side of the Colorado River with 1 water source and 5 sample sites (see site map). The government requests the contractor provide a cost for the following, also to include option years:

• The contractor will furnish all labor and materials necessary to collect and analyze drinking water samples for the two existing drinking water systems. The contractor will work directly with the field office to develop a sampling plan that will meet all the requirements for the Counties of Imperial, CA, La Paz, AZ, and ADEQ requirements. The contractor will coordinate with YFO to agree on the analytical methods used that will detect all contaminates in question. The analysis for the government samples will be at a laboratory approved for drinking water analysis by Imperial County Department of Health Services La Paz County and

ADEQ.

• The services rendered shall be to perform testing for monthly Coliform and annual Nitrate/Nitrite sampling for the purposes of complying with all Federal and State of AZ and CA drinking water regulations and as required for water and related technical services and assistance as directed. Contract to include a rush analysis service this is a requirement that the contractor must take the required three repeat samples within 24 hours of a repeat sample testing positive, see CASHE Finding PW-20-CA91 attached.

• All testing services performed shall conform to the Safe Drinking Water Act (SOWA), United

States Environmental Protection Agency (EPA) regulations, National Pollutant Discharge Elimination System (NPDES), Clean Water Act (CWA) and any other state and/or federally mandated regulations and use current EPA approved test methods or EPA authorized and approved equivalent methods. Laboratories performing tests under this contract must be certified to perform drinking water analyses in the following programs: by Imperial County Department of Health Services (ICDHS), La Paz County and ADEQ.

General Tasks:

1. Assume Certified Water System Operator oversight and action responsibility for the two identified water systems. This action includes providing and applying necessary treatment chemicals, tests and test materials, providing treatment system maintenance, generating and filing all applicable system reports and ensuring quality control of the potable system.

2. Update/Prepare a Sampling and Analysis Plan (SAP) which describes the sampling locations, numbers, and types of samples to be collected, and the quality control requirements of the project.

3. The Contractor shall provide the following rush analysis services when a positive test result is present and notify the ASO Contract Officer or its designated representative of the test results by telephone and e-mail confirmation.

a) This contract will include provisions for rush analysis services requiring the sampling contractor to take the required repeat samples (up to 4) within 24 hours of being notified of a positive coliform routine sample.

4. All analysis performance and reporting shall be compliant with all current Federal and State of California and Arizona minimum detection limits (MDLs) and minimum reporting levels (MRLs).

5. Collect samples in an area free of excessive dust, rain, snow, or other sources of contamination.

6. Select a cold-water faucet for sampling which is free of contaminating devices such as screens, aeration devices, hoses, purification devices or swiveled faucets. Check the faucet to be sure it is clean. If the faucet is in a state of disrepair, select another sampling location.

7. Collect samples from faucets which are high enough to put a bottle underneath without contacting the mouth of the container with the faucet.

8. Open the faucet and thoroughly flush. Generally, 2 to 3 minutes will suffice, however longer times may be needed, especially in the case of lead distribution lines. Typically, the water temperature will stabilize which indicates flushing is completed. Once the lines are flushed, adjust the flow so it does not splash against the walls of the bathtub, sink or other surfaces.

9. Fill out the chain of custody form with the sample collection information. Record the site location, name of the sampler, date and time of collection, method of collection, type of analysis to be completed, and preservative in use.

10. Deliver or ship samples to the laboratory to ensure that holding times are met. Holding time starts at sample collection and ends at preparation and/or analysis. Be sure to allow time for the laboratory to process the samples.

11. If a TC positive result occurs, the contractor should contact BLM immediately and perform appropriate testing/samples in alignment with the Total Coliform Rule.

12. Work with BLM local office to designate a point of contact/record keeper to review and maintain records results to include annual nitrate and nitrite testing results.

13. Take coliform samples early in the month to ensure that repeat samples can be taken in the same month.

14. Contact the State, County, and BLM CASHE Program Lead (Ken Morin at 303-231-6418 or kmorin@blm.gov) following a positive repeat sample for guidance on what actions should be taken.

15. BLM/YFO will be responsible to post public notifications of MCL violations when applicable and maintain a copy of the violations provided by the contractor.

2.0 SAMPLE COLLECTION METHOD

AquaPulse and/or Eaton Laboratories accepts samples for coliform, nitrate, and nitrite for analysis Monday through Wednesday. Samples must be Shipped to the laboratory by 3:00 PM. Samples should be taken at the beginning of the week to ensure holding times are met.

1. Use sample containers and chain of custody from the laboratory and place them in a clean zip lock bag.

2. Fill out the lab chain of custody. The Laboratory chain of custody should be used for all water samples.

3. Before taking the sample, label the sample container with the same information as the chain of custody. Put the labeled container back into the zip lock bag.

4. Locate the proper sampling site and remove any attachments such as hoses, screens, and aerators. Reinstall these items after the sample is taken.

5. Thoroughly flame the faucet using a small propane torch or cigarette lighter for 1 to 2 minutes or until any leaking water dries. Do not heat the faucet excessively as it may damage rubber seals. Or use chlorine spray bottle to clean faucet.

6. Turn on the water and let it run at a steady stream until a temperature change is felt. Do not run the tap for more than 5 minutes. Do not open the tap as far as it will go. A very high flow or sudden changes in water pressure can dislodge sediment and make the sample unusable. Before collecting the sample, turn the water down so that the stream is the width of a pencil.

7. Remove the labeled container from the zip lock bag and unscrew the cap. Hold the cap on its outer edge being careful that fingers do not come in contact with the underside, as the underside will come in contact with the sample.

8. Hold the open container well below the rim. Place the container under the running water being careful to avoid water splashing onto the sampler’s hands. Splash-back from the sampler’s hands into the container has the potential to contaminate the sample.

9. Do not use a sample container if the cap was not originally screwed on tightly, as it may have been tampered with or otherwise contaminated.

10. Do not set the sample container or cap on the ground. Coliform bacteria are present in the soil and contact with the ground may contaminate the sample.

11. Hold the sample container below the rim and fill the bottle to the neck or indicated fill line, ensuring the lab has enough water to run the test. Do not allow the container to overflow. [Note: A 100 milliliter (mL) sample is required for coliform sampling.

An air space should be provided in the container.]

12. Replace the cap as soon as the sample container is full and removed from the flow of water.

13. Re-sample using an extra sample bottle if the sample container or its cap is dropped on the ground before, during, or after sampling.

14. Place the labeled sample container and completed lab slip in a zip lock bag.

Place the sealed bag in a clean cooler. Samples should be chilled to 4°C (39°F) using wet ice.

15. Turn off the water and replace any attachments.

16. Deliver samples to the lab. Analysis of the sample must begin within 30 hours.

The lab will reject samples if the holding time is exceeded.

Note: When filling out the chain of custody, it is imperative that the sample location be written as indicated in this plan. If a positive coliform result is reported and the sample location on the form is not noted as described in this plan, it will be difficult to determine which tap was sampled. Because the location of the repeat samples is dependent on the location of the original sample, using consistent sampling location designations is important. If the exact sample location is not consistently noted, it will also be difficult to use historic results in a trend analysis conducted to determine the source of coliform contamination.

3.0 ROUTINE COLIFORM MONITORING

Coliform analysis must be performed at an Arizona DEQ-certified laboratory. Monitoring results are to be organized by date and maintained in the water system file.

3.1 Maximum Contaminant Level (MCL) for Coliform

The MCL for bacteriological contamination (i.e., coliform contamination) in a water system that takes fewer than 40 samples in a month is “no more than one positive result” in a month. The

La Posa Campground typically takes two routine coliform samples a month. Therefore, the MCL for coliforms is violated if two samples test positive for coliforms in a month.

In other words, to violate the coliform MCL, a routine monthly sample must test positive and one or more of the repeat samples must also test positive. A coliform MCL violation may also occur if two or more additional routine samples test positive.

3.2 Coliform Sample Quantity and Location

1. Collect one routine coliform sample from the predetermined sample site shown in Table 1 and Figure 1.

2. Collect the sample in a sterilized sample container provided by the laboratory and follow the procedures described in Section 2.0 of this plan.

3. If a sample is not taken during a month, a public notification must be prepared and posted. See Section 9.0, Public Notifications, and Appendix A for detailed guidance on the required content and when the notice must be posted.

4. Submit a copy of the certified public notification to the Arizona Department of Environmental Quality (ADEQ) within 10 days of its posting.

5. File a copy of the forwarding letter to ADEQ and the public notification, including the certification, with the monitoring results.

Table 1 – Coliform Sampling Locations

Month Sample Location January HBS 001 and 004 February HBS 002 and 003 March HBS 001 and 004 April HBS 002 and 003 May HBS 001 and 004 June HBS 002 and 003 July HBS 001 and 004

August HBS 002 and 003 September HBS 001 and 004

October HBS 002 and 003 November HBS 001 and 004 December HBS 002 and 003

Coliform sample locations are selected and assigned to ensure that all sections of a water distribution system are sampled throughout the year or operating season. At least one sampling location has been chosen for each major portion and each isolated portion of the water distribution system. Sampling the isolated portions and low-pressure areas of distribution systems is recommended because those areas are most likely to have bacteriological contamination.

Always sampling in the same section of a distribution system biases the coliform sampling results. Water provided from a faucet in one building can be contaminated even if a sample from another tap is absent of coliform contamination. Hairline cracks in the piping, a cross connection, or a submerged valve or tap in the distribution system each could provide a pathway for coliform contamination.

3.3 When Routine Coliform Samples Must be Taken

1. The first week of the month. This is necessary to ensure that, if a routine sample tests positive for coliforms, the required four repeat samples can be taken the same month the positive result occurs.

2. It is necessary to ensure the laboratory is open and will be able to begin the analysis before the 30-hour holding time is exceeded.

3. If a monthly routine sample is not taken, a public notification will be prepared and posted. See Section 9.0, Public Notifications, and Appendix A for detailed guidance on the required content and when the notice must be posted.

3.4 What Actions Must be Taken if a Routine Coliform Sample Tests Positive

1. Take four repeat samples within 24 hours of being notified by the laboratory of the positive routine result. See Section 4.0, Repeat Coliform Sampling, for detailed guidance on these samples.

2. Attempt to find the cause or source of the positive result.

3. If the sample is positive for E. coli, consult with management and the State Engineer on whether the water system should be shut down until it tests absent of coliforms.

4. Take five additional routine samples the next month the system provides water to employees or the public. These samples must be taken regardless of whether any of the repeat samples test positive. See Section 5.0, Additional Routine Coliform Sampling, for detailed guidance on these samples.

3.5 Summary of Actions That Must be Taken if the Coliform MCL is Exceeded

1. Prepare and post a public notification that has been certified by local management (e.g., Area or District Manager) by having it signed on the second page (i.e., certification portion of the public notification). This certifies that the notification has been prepared and posted in accordance with the appropriate regulations.

2. Select the appropriate notice from Appendix A, and complete it in accordance with the requirements in Section 9.0, Public Notification.

3. Inform ADEQ immediately after learning of the MCL violation, clarify whether any results were positive for E. coli, and ask for further guidance.

4. Inform local management and the State Engineer of the MCL violation, clarify whether any results were positive for E. coli, and ask for further guidance.

5. Document guidance received from ADEQ, management, and engineering noting the name, title, and telephone number of the State regulator, manager, or engineer, the actual guidance received, date, and time of the call. Document the same information even if it is provided in a voice mail.

6. Implement guidance received from ADEQ, management, and/or engineering.

7. Submit a copy of the public notice and certification to ADEQ within 10 days of its posting.

8. File a copy of the forwarding letter to ADEQ and the public notification, including the certification, with the monitoring results.

9. Attempt to find the source or cause of the positive coliform results.

10. Take either repeat samples within 24 hours of being notified of the MCL violation or additional routine samples the next month the system provides water to the public, depending on the circumstances.

4.0 REPEAT COLIFORM MONITORING

Repeat samples must be collected whenever a routine sample tests positive for coliform contamination. [Note: Investigative samples are not considered routine or repeat samples.] The primary reasons for taking repeat samples are to verify the initial positive result and to determine if the bacteriological contamination is limited to a single tap or is widespread in the distribution system.

4.1 Repeat Coliform Sample Quantity and Location

Do not disinfect the system prior to taking repeat samples. Disinfecting the well or distribution system after a positive routine coliform sample defeats the purpose of determining if the initial positive result was due to sampling error, or if the contamination is widespread or isolated.

1. Collect four repeat coliform samples from the predetermined sample locations indicated in Table 2 and Figure 1 within 24 hours of being notified of the positive result by the laboratory.

Table 2 – Repeat Coliform Sample Locations

Location of Positive Sample Repeat Sample Locations 1 Original sample site 2 Manager’s house 3 Welcome building 4 well

2. Collect the sample in a sterilized sample container provided by the laboratory and follow the procedures described in Section 2.0 of this plan.

3. Prepare and post a public notification if the repeat samples are not taken or if less than four repeat samples are taken. See Section 9.0, Public Notifications, and Appendix A for detailed guidance on the required content and when the notice must be posted.

4.2 When Repeat Coliform Samples Must be Taken

1. Take all four repeat samples within 24 hours of being notified of the positive routine result by the laboratory.

2. Contact ADEQ if the repeat samples cannot be taken within 24 hours of being notified.

Examples of reasons the repeat samples cannot be taken within the 24-hour time period include the laboratory being closed or doing so poses a work conflict (e.g., notification was received too late on Friday and sampling on Saturday would require overtime). Take repeat samples as directed by ADEQ, but no longer than 3 days after being notified by the laboratory.

3. If the repeat sample cannot be taken within 24 hours, document the conversation with ADEQ or the voice mail message left with ADEQ, noting the name, title, and telephone number of ADEQ regulator and comments or direction provided in regards to when the four repeat samples must be taken.

4. If the routine sample tested positive for E. coli, the four repeats must be taken within 24 hours.

4.3 What Actions Must be Taken if One or More Repeat Samples Tests Positive for Coliforms

1. Prepare and post a public notification that has been certified by local management (e.g., Area or District Manager) by having it signed on the second page (i.e., certification portion of the public notification). This certifies that the notification has been prepared and posted in accordance with the appropriate regulations.

2. Consult Table 3 to determine if the MCL violation is a Tier 1 or Tier 2 violation.

3. A Tier 1 violation has occurred if the routine or any of the repeat samples are positive for E. coli.

4. A Tier 1 violation public notification must be posted within 24 hours.

5. A Tier 2 violation has occurred if repeat coliform results are positive for total coliform and no positive E. coli results are received.

6. A Tier 2 violation public notification must be posted within 30 days.

7. Inform ADEQ immediately after learning of the MCL violation, clarify whether any results were positive for E. coli, and ask for further guidance.

8. Inform local management and the State Engineer of the MCL violation, clarify whether any results were positive for E. coli, and ask for further guidance.

9. Document guidance received from ADEQ, management, and engineering noting the name, title, and telephone number of the State regulator, manager, or engineer, the actual guidance received, date, and time of the call. Document the same information even if it is provided in a voice mail.

10. Select the appropriate notice from Appendix A and complete it in accordance with the requirements in Section 9.0, Public Notification.

11. Ensure the notification is certified by local management (e.g., Field Office or District Manager) by having it signed on the second page (i.e., certification portion of the public notification). This certifies that the notification has been prepared and posted in accordance with the appropriate regulations.

12. Post the completed and certified public notification within the required time frame.

13. Submit a copy of the public notice and certification to ADEQ within 10 days of its posting.

14. File a copy of the forwarding letter to ADEQ and the public notification, including the certification, with the monitoring results.

15. Take five additional routine samples the following month the system is in operation. See Section 5.0 for additional details.

16. Attempt to find the cause of the positive coliform results.

17. Disinfect the water system.

5.0 ADDITIONAL ROUTINE COLIFORM MONITORING

The primary reason for taking five additional routine samples is to collect a statistically valid number of samples over an extended time period to determine whether the coliform contamination was isolated or widespread, and whether the corrective action taken following the positive coliform result prevents a recurrence of coliform contamination over the long term.

Taking all additional routine samples from the same tap on the same day does not provide the statistically valid data needed to determine if the corrective actions taken following a positive coliform result have eliminated the source of the coliform contamination.

5.1 Additional Routine Samples Quantity and Location

1. Collect five routine coliform samples: one sample from the tap that initially tested positive and four others from sample locations 1, 2, 9, and 5. If the tap that initially tested positive is one of the four listed sample locations, a different fifth sample location must be sampled. If two or more taps initially tested positive for coliforms, it is not required to sample from all four of the listed sampling locations, as long as five samples are taken.

The intention is to take one sample from the location of the original positive result, another from the location closest to the well, and the remaining from locations farthest from the well.

2. Collect the samples using sterilized sample containers provided by the laboratory following the procedures described in Section 2.0 of this plan.

3. Prepare and post a public notification if the additional routine samples are not taken or if less than five samples are taken. See Section 9.0, Public Notification, and Appendix A for detailed guidance on the required content and when the notice must be posted.

4. Submit a copy of the public notice and certification to ADEQ within 10 days of its posting.

5.2 When Additional Routine Coliform Samples Must be Taken

Take all five additional routine samples between the 10th and 15th of the next month the water system provides water to the public or employees following the initial positive routine result. As an example, if the routine coliform taken in April tests positive, five additional routine samples are to be taken in May if the water system is open. If the water system is closed after the positive result in May, and does not reopen until July, the five additional routine samples must be taken in July.

5.3 What Actions Must be Taken if One or More Additional Routine Samples Tests Positive for Coliforms

1. Begin the repeat sampling process again. See Section 4.0 for details on the samples that must be taken.

2. Prepare and post a public notification if more than one additional routine sample tested positive because the coliform MCL has been violated. See Section 9.0, Public Notification, and Appendix A for the sample notifications that must be completed and posted.

3. Consult Table 3 to determine if the MCL violation is a Tier 1 or Tier 2 if more than one additional routine sample tests positive.

4. A Tier 1 violation has occurred if the routine or any of the repeat samples are positive for E. coli.

5. A Tier 1 violation public notification must be posted within 24 hours.

6. A Tier 2 violation has occurred if the repeat coliform results are positive for total coliform and no positive E. coli results are received.

7. A Tier 2 violation public notification must be posted within 30 days.

8. Inform ADEQ immediately after learning of the MCL violation, clarify whether any additional routine sample results were positive for E. coli, and ask for further guidance.

9. Inform local management and the State Engineer of the MCL violation, clarify whether any additional routine sample results were positive for E. coli, and ask for further guidance.

10. Document guidance received from ADEQ, management, and engineering noting the name, title, and telephone number of the ADEQ regulator, manager, or engineer, the actual guidance received, date, and time of the call. Document the same information even if it is provided in a voice mail.

17. Attempt to find the cause of the positive coliform results.

18. Disinfect the water system.

6.0 NITRATE MONITORING

The minimum monitoring requirements for any BLM water system are for coliforms and nitrate/nitrite because all are acute contaminants. Individuals consuming drinking water contaminated with coliforms and nitrate/nitrite can become sick in a couple of days.

6.1 Nitrate Maximum Contaminant Level

The MCL for nitrate is 10.0 mg/L as nitrogen. This is equivalent to a concentration of 45.0 mg/L of nitrate.

6.2 Nitrate Sample Quantity and Location

1. Collect one sample from sample location 1 because it is the closest to the well.

2. Take the sample using the container provided by the laboratory.

3. Prepare and post a public notification if a nitrate sample is not taken. See Section 9.0, Public Notification, and Appendix A for detailed guidance on the required content and when the notice must be posted.

4. Submit a copy of the certified public notification to ADEQ within 10 days of its posting.

6.3 When Nitrate Samples Must be Taken

Collect the annual sample in January.

6.4 What Actions Must be Taken if Annual Nitrate Sample Concentration Exceeds the MCL of 10 mg/L

Compliance with the MCL for nitrate is determined based on one sample, if the concentration of this contaminant is below the MCL. If the nitrate concentration exceeds the MCL in the initial sample, compliance with the MCL is determined based on the average of the initial and confirmation samples.

1. Take a confirmation sample within 24 hours of receiving the initial sample result.

2. Prepare and post a public notification if a confirmation sample is not taken within 24 hours. The notification must state that the nitrate MCL has been violated and the notification must be posted on site within 24 hours. Under this circumstance, a sample must be taken and analyzed within 2 weeks of receiving notification of the analytical results of the initial sample.

3. Take the confirmation sample.

4. Prepare and post a public notification if the average of the annual and confirmation sample exceeds the MCL.

5. Select the appropriate notice from Appendix A, and complete it in accordance with the requirements in Section 9.0, Public Notification.

6. Ensure the notification is certified by local management (e.g., Area or District Manager) by having it signed on the second page (i.e., certification portion of the public notification).

This certifies that the notification has been prepared and posted in accordance with the appropriate regulations.

7. Post the completed public notification within 24 hours.

8. Inform ADEQ of the nitrate MCL violation and ask for further guidance.

9. Inform local management and the State Engineer of the nitrate MCL violation and ask for further guidance.

12. Submit a copy of the public notice and certification to ADEQ within 10 days of its posting.

13. File a copy of the forwarding letter to ADEQ and the public notification, including the certification, with the monitoring results.

7.0 NITRITE MONITORING

ADEQ requires that transient, noncommunity water systems be monitored for nitrite every 9 years. So as not to overlook the 9-year cycle, take the nitrite sample every year at the same time as the nitrate sample.

7.1 Nitrite Maximum Contaminant Level

The MCL for nitrite is 1.0 mg/L as nitrogen.

7.2 Nitrite Samples Quantity and Location

1. Collect the nitrite sample at the same time as the annual nitrate sample.

2. Collect one sample from sample location 1 because it is the closest to the well.

3. Take the sample using the container provided by the laboratory.

4. Prepare and post a public notification if a nitrite sample is not taken at least once every 9 years. See Section 9.0, Public Notification, and Appendix A for detailed guidance on the required content and when the notice must be posted.

7.3 When Nitrite Samples Must be Taken

Collect the annual sample in January.

7.2 What Actions Must be Taken if an Annual Nitrite Result is Greater Than or Equal to 50% of the 1.0 mg/L MCL, but Less Than 1.0 mg/L

1. Take a quarterly sample for at least 1 year following any nitrite result where the concentration was greater than or equal to 0.50 mg/L, but less than 1.0 mg/L.

[Note: Quarterly nitrite monitoring may be discontinued if, after 1 year, the nitrite results are consistently below 1.0 mg/L.]

2. After 1 year of quarterly sampling results less than 1.0 mg/L nitrite, consult with ADEQ regarding resuming annual nitrite monitoring. ADEQ will likely require monitoring for nitrite during the quarter in which the highest nitrite concentrate was reported, pursuant to Federal regulations.

3. Prepare and post a public notification if a nitrite sample is not taken. See Section 9.0, Public Notification, and Appendix A for detailed guidance on the required content and when the notice must be posted.

4. Submit a copy of the certified public notification to ADEQ within 10 days of its posting.

7.5 What Actions Must be Taken if a Nitrite Result Exceeds the MCL of 1.0 mg/L

Compliance with the MCL for nitrite is determined based on one sample if the levels of these contaminants are below the MCLs. If the levels of nitrite exceed the MCL in the initial sample, compliance with the MCL is to be determined based on the average of the initial and confirmation samples.

1. Take a confirmation sample within 24 hours of receiving the initial sample results.

2. Prepare and post a public notification if a confirmation sample cannot be taken within 24 hours. The notification must state that the nitrite MCL has been violated and it must be posted onsite within 24 hours. Under this circumstance, a sample must be taken and analyzed within 2 weeks of receiving notification of the analytical results of the initial sample.

3. Prepare a public notification if the average of the annual and confirmation sample exceeds the MCL. The notification must be posted onsite within 24 hours.

4. Inform ADEQ immediately after learning of the MCL violation and ask for further guidance.

1. Read the descriptions for each type of public notification: Tier 1, Section 9.1; Tier 2, Section 9.3; and Tier 3, Section 9.5; to determine the correct classification of the violation.

2. Select the appropriate public notice located in Appendix A. Fill in the required information, and laminate the notice for durability. The public notifications are two sided.

3. Complete the certification block located on the backside of the public notice. This block must be completely filled out prior to laminating the notice.

4. Post all public notifications conspicuously at hydrants and hosebibs, the kiosk, and site entrance.

5. Notify the host as soon as possible.

9.1 What is a Tier 1 Violation?

A Tier 1 violation exists, and a certified public notification must be prepared and posted, when one or more of the following events occur:

1. Coliform MCL violation - a repeat sample tests positive for coliforms, and E. coli are present in either the routine or any of the repeat samples (see Table 3). [Note: A repeat sample is only taken if a routine sample tests positive for coliforms.]

2. Coliform MCL violation - two or more additional routine samples test positive for coliforms, and E. coli are present in one or more of the samples (see Table 3).

3. Coliform monitoring violation - failure to test for E. coli when any repeat samples test positive for coliform.

4. Nitrate MCL violation – the average of the initial and confirmation sample concentration exceeds 10.0 mg/L (nitrate as nitrogen).

5. Nitrate monitoring violation - failure to take a confirmation sample within 24 hours of being notified by the laboratory of any sample showing exceedance of the nitrate MCL.

6. Nitrite MCL violation – the average of the initial and confirmation sample concentration exceeds 1.0 mg/L (nitrite as nitrogen).

7. Nitrite monitoring violation - failure to take a confirmation sample within 24 hours of being informed by the laboratory of any sample showing exceedance of the nitrite MCL.

8. An occurrence of a waterborne disease outbreak or other waterborne emergency that is attributed to the Burro Creek Campground water system.

9. Other Tier 1 situations may exist as determined by ADEQ, local management, or the State Engineer.

9.2 What Actions Must be Taken if a Tier 1 Violation has Occurred?

1. Consult with ADEQ the next business day of the Tier 1 violation to receive direction on subsequent requirements. Failure to report a violation or potential public health situation is also a violation. The water system operator must consult ADEQ for required course of action.

2. Document the name of the person contacted at ADEQ, name of the person spoken with, telephone number, the date of the contact, and the direction received. Follow the guidance provided by ADEQ on how to proceed. Document the same information even if it is provided in a voice mail.

3. Inform local management and the State Engineer of the Tier 1 violation and ask for further guidance. Document and follow the guidance on how to proceed.

4. Determine which public notice in Appendix A (two sided) is appropriate, and fill in the required information.

5. Ensure the Area or District Manager signs the second page (i.e., the certification portion of the public notification), certifying that the notification has been prepared and posted in accordance with appropriate regulations.

6. Laminate the notice for durability after it is certified.

7. Post the public notification within 24 hours, and provide a copy to the host.
