2.2 System Description
The Pumphouse Campground water system is a small water system that is used to supply water to campground users and BLM personal. The campground is located along the Colorado River approximately 13 miles south west of Kremmling, CO. The system is supplied water from a single well. The distribution system consists of two separate buried water lines. The system is a seasonal system which is typically open April-October depending on temperatures. The system is drained at the end of each season.
2.3 Water Types
Groundwater (GW) – Any water under the surface of the ground being neither “surface water” nor “groundwater under the direct influence of surface water.”
2.4 Availability
Seasonal (S) – A water facility that is typically used every year to aid a system in meeting high water demands. While a water system may not know when it will need a seasonal source, it is most often used every year. These also may be referred to as peaking facilities. Routine sampling will be required at the Entry Point to the Distribution System.

Provide a Detailed Description of the Water Treatment System (including descriptions of tanks used for disinfection contact time)
Well water is pumped through sediment filter and then through a proportional chemical injection system.
NSF certified Sodium Hypochlorite (bleach) is dosed proportionally with water systems flow. Treated water enters a pressure tank and from there into a 120 gallon baffled contact/storage tank prior to distribution.
Note – Sodium Hypochlorite (bleach) degrades over time. Policy recommendation for changing the chlorine/water mixture in the Chlorine Solution Tank is every 30 days, with the maximum replacement time of 60 days. Instructions on how to mix chlorine/water solution can be found in Section 11.8.

5.0 Distribution System Details
5.1 Definitions
Entry point –A location before or at the first customer which is representative of treated (finished) water. The entry point may represent treated water from multiple treatment plants and/or multiple sources. Sometimes the water treatment plant is the first tap.
Distribution system storage facility – Any treated (finished) water storage tank at the treatment plant or in the distribution system that is not considered part of disinfection contact time (i.e.
after the entry point).
5.2 Distribution System Information
The distribution systems consist of 2 independent buried water lines. Waterline #1 and Waterline #2. Each waterline branches from the main treated waterline immediately downstream of the disinfection system.

Phone: 303-692-3048
8.2 Routine Sampling Information
Number of routine total coliform samples to be collected each month: 3/Month, see “Table 1” for sample locations.
Seasonal systems must obtain a safe total coliform result approximately 10 days prior to opening for the season. For complete instruction of startup for the water system, see “Start-up Procedures for BLM Pumphouse Recreations Site Water System”.
The routine samples represent the entire distribution system. Raw Water Tap represents water quality in the well, Treated Water Tap represents the chlorinated water (Treated Water). Taps #1, #2, #3 represent water quality within Waterline #1. Taps #4, #5, #6 and #7 represent water quality within Waterline #2.
Samples shall be taken during the first week of each month, and taken early in the day, early in the week and as noted for seasonal start up.
The total coliform MCL is exceeded for this system if there are 1 or more positive sample in a calendar month.

8.3 Actions To Be taken When Routine Coliform Samples are NOT Taken
1. If a monthly samples are not taken, a Tier 3 public notification must be prepared and posted. See Section 12.0, Public Notifications and Appendix A for detailed guidance on the required content and when the notice must be posted.
2. Ensure the notification is signed on the second page by the Field Office Manager. This certifies that the notification has been prepared and posted in accordance with the appropriate regulations. Send a copy of the signed notification to CDPHE Drinking Water Program within 10 days of posting.
3. Post the completed public notification on all information kiosks at the campground within 30 days.
4. File a copy of the public notification with the monitoring results.
8.4 Actions To Be taken When Routine Coliform Sample Tests Positive
1. Ensure that the laboratory tests the sample for E. coli. State-certified laboratories should test positive total coliform samples for E. coli automatically, but the water system should verify that this has been completed.
2. Take 3 repeat samples plus 1 Ground Water Rule-triggered monitoring sample within 24 hours of notification of a positive routine sample.
3. To comply with the Ground Water Rule, after a positive coliform result, in addition to the three repeat samples, a sample must be taken from the well or sample tap closest to the well prior to
BLM Pumphouse Recreation Site Monitoring Plan – PWSID#CO0225625 Page 15 of 45 treatment. The Ground Water Rule refers to this sampling as triggered monitoring. Therefore, in the event of a positive coliform sample, the system must sample the tap closest to the source prior to treatment. The sample tap closest to the well is “Tap #1”.
4. Repeat samples shall be taken from the same tap as the original positive coliform sample and at the taps as shown in the “Repeat Coliform Sample Taps” shown on Table 2.
5. Repeat sample process must be repeated until a complete set of repeat samples are total coliform negative.
6. Attempt to find the cause or source of the positive result.
7. If the sample is positive for E. coli, the water system is to be immediately shutdown to prevent use.
Notify CDPHE Drinking Water Program, BLM Field Office Manager, and State Water Coordinator within 24 hours of the positive result. The water system must remain shut down until samples are absent of coliforms.
8.5 Repeat Coliform Monitoring
1. Collect three repeat coliform samples plus one Ground Water Rule-triggered monitoring sample from the predetermined sample taps indicated in the “Repeat Coliform Sample taps” table below. Collect repeat samples within 24 hours of being notified of the positive result by the laboratory.

2. If any or all of the three repeat samples are not taken or if the Ground Water Rule-triggered monitoring sample is not taken complete the following:
a. Perform a Level 1 assessment. See Section 9.0, Treatment Technique Triggers and
Assessments and Appendix B for detailed guidance on how to perform the assessment.
b. Prepare a Tier 3 public notification and post it on all kiosks or bulletin boards located within the campground within 30 days (See Section 12.0, Public Notifications, and Appendix A).
Ensure the notification is signed on the second page by the Field Office Manager. This certifies that the notification has been prepared and posted in accordance with the appropriate regulations.
c. Send a copy of the certified public notification that was signed by the BLM Field Office Manager to CDPHE-Drinking Water Program within 10 days of posting the public notification.
d. File a copy of the public notification, including the certification and the letter that accompanied the notification to CDPHE-Drinking Water Program with the monitoring results.
8.6 Actions to be Taken if One or More Repeat Samples Tests Positive for Total Coliform
1. If one or more of the repeat samples tests positive for total coliforms ONLY, a Level 1 Assessment must be performed within 30 days. See Section 9.1, When and How to Perform a Level 1 Assessment, and Appendix B for detailed guidance. This is referred to as a “triggered assessment” and the maximum contaminant level (MCL) is NOT violated. NOTE: If a second Level 1 assessment is triggered within a 12-month rolling period, a Level 2 assessment must be performed.
2. Inform the CDPHE Drinking Water Program, BLM Field Office Manager and State Water Coordinator within 24 hours of the positive repeat sample, clarify that the results were positive for total coliforms only, and that a Level 1 assessment will be performed.
3. Document guidance received from CDPHE-Drinking Water Program if applicable.
8.7 Actions to be Taken when Monthly or Repeat Samples Test Positive for E. coli or One or More Repeat Samples Test Positive for Total Coliforms
1. If the sample tests positive for E. coli, the water system is to be immediately shutdown and all taps closed to prevent their use. Notify CDPHE Drinking Water Program, BLM Field Office Manager and State Water Coordinator within 24 hours of the positive result. The water system must remain closed until samples are absent of coliforms. Document guidance received from CDPHE Drinking Water Program and BLM personal.
2. Document guidance received from CDPHE-Drinking Water Program, local management, and BLM State Water Coordinator, noting the actual guidance received, date, and time of the call. Document the same information even if it is provided in a voice mail.
3. Implement the guidance provided by CDPHE-Drinking Water Program, local management, and BLM State Water Coordinator.
4. Prepare a Tier 1 public notification and post it on all information kiosks and bulletin boards within the campground within 24 hours (See Section 12.0, Public Notifications, and Appendix A).
5. Ensure the notification is signed by the Field Office Manager.
6. Send a signed copy of the notification to CDPHE Drinking Water Program within 10 days of posting and file a copy of the public notification with the monitoring results.
7. Arrange to have CDPHE Drinking Water Program or a 3rd party approved by CDPHE to perform a Level
2 assessment within 30 days. See Section 6.3, How to Perform a Level 2 Assessment, and Appendix B for detailed guidance.
BLM Pumphouse Recreation Site Monitoring Plan – PWSID#CO0225625 Page 17 of 45
8. Ensure that the Level 2 assessment is performed, corrective actions are completed, and documentation of their completion is sent to CDPHE Drinking Water program within 30 days of the triggering of the Level II assessment. If all of these items cannot be completed within 30 days negotiate a schedule for their completion with CDPHE-Drinking Water Program.
If unsure as to what must be done, consult Table 3 to determine whether a Level 1 or Level 2 assessment is triggered and if a public notification must be prepared and posted. See Section 9.0, Treatment Technique Triggers and Assessments, for detailed guidance on performing the assessment. See Section 12.0, Public Notifications, and Appendix A for detailed guidance on the required content and when the notice must be posted.
8.8 Routine Monitoring After a Positive Sample
Seasonal systems on monthly monitoring schedules are no longer required to collect “temporary routine” bacteriological samples the following month after a total coliform-positive sample result.
Return to routine monthly monitoring.

8.9 Residual Disinfectant Monitoring
Distribution System Residual Disinfectant Monitoring The residual disinfectant must be measured at the same time and the same location as each total coliform bacteria sample. Measurements must be conducted in the field by a certified operator or under the direction of the certified operator and must be written on each total coliform chain of custody when it is submitted to the laboratory.
Disinfectant used in the distribution system: Sodium Hypochlorite (bleach)
Residual disinfectant quality assurance/quality control (QA/QC) – explain the exact procedures to be followed to ensure that the field test measurement will be accurate. This may be found in the manufacturer’s literature: Free chlorine residual shall be measured as instructed by the Hach Pocket II Colorimeter instruction manual. Samples shall be taken at the Treated Water Tap and each of the samples tap designated for the start-up or scheduled monthly coliform bacteria sample. See locations for samples on Table 1.
BLM Pumphouse Recreation Site Monitoring Plan – PWSID#CO0225625 Page 18 of 45
After system disinfections as described in the start-up procedures, and before opening of the water system, multiple free chlorine residual samples may be required while adjusting the free chlorine residual to be within acceptable limits. Free chlorine residual shall not fall below 0.2mg/L or exceed 4.0 mg/l while supplying water to users.
8.10 Residual Disinfectant Monitoring Treatment Technique Compliance Determination
The system is required to maintain a detectable residual disinfectant level in the distribution system. The minimum detectable level is 0.2mg/L.
BLM Pumphouse Recreation Site Monitoring Plan – PWSID#CO0225625 Page 19 of 45
9.0 Treatment Technique Triggers and Assessments
Water systems are required to perform and document assessments to identify and correct defects that could provide a pathway of entry for microbial contamination into the distribution system or that are indicative of a failure or imminent failure in a barrier that is already in place.
There are two levels of triggered assessments, Level 1 and Level 2. The assessment level depends on the trigger’s potential impact to public health.
9.1 When and How to Perform a Level 1 Assessment
A Level 1 assessment is triggered if one of the following occurs:
A routine sample tests positive for only total coliforms and one or more of the repeat samples tests positive for only total coliforms; or All three repeat samples and the Ground Water Rule-triggered monitoring sample are not collected following a positive coliform sample.
1. A Level 1 assessment is a basic examination of the source water, treatment, distribution system, and relevant operational practices. It is intended as a self-assessment and is typically performed by a person or persons responsible for the system or with BLM personnel who are knowledgeable of the water system, or approved CDPHE Drinking Water program third-party consultants.
2. Perform and document the assessment within 30 days of the trigger.
3. Public water systems are required to follow CDPHE Drinking Water Program Level 1 Assessment procedures. See Appendix B for more information.
9.2 When to Perform a Level 2 Assessment
1. Any of the three repeat samples or the Ground Water Rule-triggered monitoring sample test positive for E. coli;
2. A routine sample tests positive for E. coli and any of the repeat samples test positive for E. coli or total coliform. This means that a Level 2 Assessment must be completed if any of the repeat samples test positive for coliforms, even if all the repeat samples test negative for E. coli.
3. Failure to take all required repeat samples following a routine sample that tests positive for E. coli;
4. Failure to test for E. coli following any repeat samples that test positive for coliform;
5. A second Level 1 assessment is required within a rolling 12-month period. Instead of performing a second Level 1 assessment, a Level 2 assessment is required. See Appendix B for more information.
9.3 How to Perform a Level 2 Assessment
1. Inform CDPHE Drinking Water Program, BLM Field Office Manager and BLM State Water Coordinator that a Level 2 assessment is required. Follow and document guidance received.
2. Ensure that the Level 2 assessment is performed, complete the Level 2 Assessment form as shown in

11.0 Instructions
The Revised Total Coliform Rule, provided in section 11.16 of Regulation 11, became effective April 1, 2016, and included:
A definition for a seasonal system public water system.
A NEW requirement that seasonal systems must complete department-approved start-up procedures each season.
11.1 System Inspection and Integrity Check
a. Look for any damage or evidence of contamination associated with any part of the waterworks that may have occurred during the offseason.
b. Inspect the wellhead and verify that the well casing is structurally sound, the well cap is tightly attached, vents are downturned with intact screens, and the electrical conduit is securely in place. Inspect the area surrounding the wellhead.
c. Inspect the water treatment equipment and tubing. Inspect storage and pressure tanks, plumbing lines, and fitting. Do a walk-through of the water distribution systems. Look at pipes, valves, and backflow prevention devices – ensure such devices have been appropriately tested. Ensure that all components of the water system operate correctly, and are repaired/replaced as needed.
11.2 Charging the Distribution System
a. Place signs on all spigots and hydrants in the water system stating, “Warning: Do Not Drink Water - Water System Maintenance Being Performed”.
b. Close all drain valves, #1-#5, by removing the plastic covers from drain valve boxes to expose curb stop. Place the curb stop key onto curb stop and turn clockwise 90 degrees until valve is closed. Note: not all curb stops are visible within standpipes, lower curb key as needed into standpipes until curb stop is located and key fits securely onto curb stop.
c. Inside of the storage building, close the valve directly upstream of the filter on the proportional injections panel. Close the drain valves on the pressure and contact tanks. Verify fitting on waterlines within the disinfection system are attached, i.e.
unions, etc. Place a bucket under the Raw Water tap or install piping below the Raw Water Tap and extend outside and downslope of the building for discharge of water.
d. Install a new sediment filter, inspect “O” ring and replace “O” ring if cracked or damaged.
e. Locate the electrical circuit panel and turn on circuit breakers for “Well Pump”.
Open the Main Water Valve and then the Raw Water Tap, to start water flowing.
Allow water to flow until water runs clear, then close Raw Water Tap. Open the valve directly upstream to the filter on the proportional injections panel.
f. On Waterline #1, hold open Taps #1, #2, and #3 on. (Use duct tape or wire, etc. to hold taps open.)
g. In storage building, slowly open Waterline #1 Valve to a maximum of ¼ open, BLM Pumphouse Recreation Site Monitoring Plan – PWSID#CO0225625 Page 23 of 45 allow water to flow approximately 2-3 minutes before fully opening. (Note:
Waterlines #1 and #2 valves are not shown on the “Disinfections System Photo” but are near the Treated Water Tap and are marked for identification.)
h. Allow water to flow through Waterline #1 for approximately 5-10 minutes to purge trapped air, and then close all spigots.
i. On Waterline #2, open Taps #4, #5, #6 and #7. (Use duct tape or wire, etc. to hold taps open.)
j. In storage building, slowly open to a maximum of ¼ in the open position, the Waterline #2 Valve” and allow water to flow approximately 2-3 minutes before fully opening. (Note: Waterlines #1 and #2 valves are not shown on the “Disinfections Photo” but are near the Treated Water Tap and are marked for identification.)
k. Allow water to flow through Waterline #2 for approximately 5-10 minutes to purge trapped air, and then close all hydrants/spigots.
11.3 Integrity Check
a. Leaks in the waterworks, especially in buried piping, provide potential conduits for contaminants to enter when the water system is drained or when system pressure is lost. To help gain a better understanding of leakage within the distribution system(s), conduct an integrity check once the system is re-pressurized as follows:
i. After filling the system with water and with all the taps turned off, switch off the power supply to the well pump. Read the water system’s pressure gauge and note the initial system pressure.
ii. After one hour, read the pressure gauge again and document the system pressure. Any pressure loss over this one hour time span indicates leaks. The pressure must remain within 15% of the original pressure.
iii. Some system leakage is to be expected; however, if pressure loss is greater than 15%, the leak must be found and repaired.
iv. Ensure that repaired/replaced distribution system components are properly disinfected (see the section below that addresses system disinfection) prior to serving water.
vi. Comparing pressure loss data from year to year can provide insight into the relative degree of leakage within the distribution systems.
11.4 System Disinfection and Flushing
a. Disinfection of waterworks is a required step in the start-up procedure.
i. Add 3 gallons of well water to the Chlorine Solution Tank along with 5 cups of
NSF Certified 8.25% bleach. (Note: Use only NSF Certified, un-scented bleach). Place tubing into Chlorine Solution Tank and verify tubing is connected properly to the Proportional Injection Panel as described in the manufacturer’s instructions. Plug panel into the outlet above the Proportional Injection Panel. Remove air from tubing as instructed in the manufacturer’s instructions. Set the control knob on the pump control located in the upper left portion of the panel to approximately 50%. Verify chlorine is being pumped into the system.
BLM Pumphouse Recreation Site Monitoring Plan – PWSID#CO0225625 Page 24 of 45
b. For seasonal systems that consist of buried water lines, the Department requires highly chlorinated water be used in accordance with American Waterworks Association (AWWA) published standards. Chlorine residual must be greater than 10mg/L after each segment of the waterworks is isolated for at least 12 hours.
i. Adjust the chlorine injection pump or increase the amount of chlorine in the chlorine solution tank until the chlorine residual is 10.0 mg/L or greater and fill all distribution lines with the chlorinated water. Allow this water to remain in the distribution system for a minimum of 12 hours.
ii. After system disinfection, be sure that any highly concentrated chlorine is flushed from the system prior to collecting the sample to be analyzed.
iii. Once disinfection is completed, the water system must be operated and allowed to return to the typical level of background chlorine residual prior to serving customers. Per Regulation 11 and effective April 1, 2016, free chlorine residual must be greater than or equal to 0.2 mg/L throughout the distribution system.
iv. Add an additional water (8-12 gallons) of well water to the solution tank and adjust the chlorine injection pump as needed to decrease the free chlorine residual so that it is greater than 0.2 mg/L but less than 4.0 mg/L. The desired free chlorine level at the “Treated Water Tap” is between 0.5 mg/L – 0.8 mg/L.
11.5 Entry Point and Distribution System Monitoring (Sampling)
a. Prior to serving water to the public for a given season, Regulation 11 requires the collection of a sample from within the distribution system and have it tested for total coliform. The sample must test absent for the presence of coliform bacteria prior to the supplier serving water to the public for that season.
b. During normal operations, total coliform samples must be collected in the distribution system every month and analyzed for chlorine residual and total coliform bacteria during the operating season.
c. Also during normal operations, all required entry point sampling must be performed in accordance with the system’s monitoring schedule.
d. An EPA approved chlorine test kit must be used to assure there is appropriate chlorine residual in the distribution system.
11.6 Additional Start-Up Requirements
a. Complete seasonal system start-up instructions, procedures, and requirements are found in the “Revised Total Coliform Rule Start-up Procedures for BLM Pumphouse Rec. Site Water System, PWSID #CO0225625. Submit appropriate paperwork to CDPHE as required.
11.7 System Shut-Down Procedures
a. Post signs that the water system is closed.
b. Locate the electrical circuit panel and turn on off circuit breakers for “Well Pump”.
Remove vacuum breaker from the contact tank drain valve and extend hose outside

c. Place bucket under Raw Water Tap and open valve to drain. Repeat process for Treated Water Tap. Leave valves open.
d. Remove sediment filter housing directly downstream of Raw Water Tap, drain water, dispose of filter, and rinse housing. Loosely re-attach housing. Open valve below filter on Proportional Injection System to drain.
e. Open PVC unions on waterline that are located upstream and downstream of pressure tank to release water trapped water.
f. Separate unions on each side of the flow meter on the Proportional Injection System to drain water from meter. Remove and drain water from ¼” tubing between the chlorine solution tank and Proportional Injection System. Disconnect ¼” tubing that flows into and out of the injection pump and drain lines. Run a few cycles on the injection pump to remove water from tubing inside housing. See manufacturer instructions if needed. Once drained, re-connect all items. Unplug the Proportional Injection System.
g. Verify “Waterline Valve #1” and “Waterline Valve #2” are open. (Note: Waterlines #1 and #2 valves are not shown on the “Disinfections Photo” but are near the “Treated Water Tap” and are marked for identification.)
h. Open all drain valves, #1-#5, by removing the plastic covers from drain valve boxes to expose curb stop. Place the curb stop key onto curb stop and turn counter-clockwise 90 degrees until valve is open. Note: not all curb stops are visible within standpipes, lower curb key as needed into standpipes until curb stop is located and key fits securely onto curb stop.
i. Hold open Taps #1-#7 one tap at a time to release trapped water. Remove vacuum breakers prior to opening if applicable.
j. Allow Drain Valves #1-#5 to remain open.
11.7 Disposal of Chlorinated Water in Solution Tank
a. Empty chlorinated water from solution tank and replace with a new chlorine/water mixture a maximum of every 60 days. Empty the solution tank in tank outside of the storage building but do not allow water to come in contact with the Colorado River.
11.8 Chlorine Solution Tank-Chlorinated Water Routine Replacement
a. Add approximately 10 gallons of well water to the Chlorine Solution Tank along with 5 cups of NSF Certified 8.25% bleach. (Note: Use only NSF Certified, un-scented bleach).
Place tubing into Chlorine Solution Tank and verify tubing is connected properly to the Proportional Injection Panel as described in the manufacturer’s instructions. Plug panel into the outlet above the Proportional Injection Panel. Remove air from tubing as instructed in the manufacturer’s instructions. Set the control knob on the pump control located in the upper left portion of the panel to approximately 50%. Verify chlorine is being pumped into the system. Add additional well water and/or adjust the chlorine injection pump as needed to decrease the free chlorine residual so that it is greater than 0.2 mg/L but less than 4.0 mg/L. The desired free chlorine level at the “Treated Water Tap” is between 0.5 mg/L – 0.8 mg/L.
