| Note to Environmental Health Specialist:                              |
|                                                                       |
| This data collection tool may be used where a thorough understanding  |
| of the integrated environmental health system of equipment,           |
| processes, people/policies, and economics is needed of an aquatic     |
| facility to better assess contributing factors during an outbreak     |
| investigation. It may also be used to assist the facility management  |
| to better control the factors that may impact the prevention          |
| practices. It should be completed in as much detail as possible. Not  |
| all the information specified may be available to environmental       |
| health specialists or applicable for every aquatic facility.          |
|                                                                       |
| Completion of the form may take several hours -- please keep in mind  |
| that this initial investment of time is quite important. In following |
| years, only changes to the facility need to be addressed after the    |
| initial data collection is done. Please do not leave sections blank.  |
| If a question doesn't apply, write N/A. If a question can't be        |
| answered please explain why. Where applicable, please specify the     |
| unit of measurement being used (e.g., meters vs. feet).               |
|                                                                       |
| Throughout this form the term "pool" will be generically used for     |
| individual water features such as spa, splash area, and water slide,  |
| as well as for a swimming pool. Use the chart below to link the       |
| collected data back to a specific aquatic feature. In the data        |
| collection, if there is more than one pool, specify whether answers   |
| apply to all pools, or just one. This form does not include space for |
| more than four pools. Use multiple forms if more pools are included   |
| (e.g., at a water park). If available, please attach a plan review    |
| diagram to this assessment. If the facility has a map, please         |
| include. If no map or plan review diagram is available, make a sketch |
| in the space provided on the last page, and/or attach labeled         |
| photographs.                                                          |
|                                                                       |
| It is recommended that if you are completing the form electronically, |
| you use a different font and/or italics for your answers. This will   |
| make the form much easier to read if additional information is added  |
| in the future to an existing form.                                    |

What is the maximum bather load standard in your state for various
facilities and sizes?

Are their policies to ensure that bather load is not exceeded?

Does the pool(s) meet current design standards?

> 2\. WATER FLOW & TREATMENT

a.  WATER SOURCE

    What is the source of water used in the pool (i.e., natural, well,
    municipal, reclaimed, etc.)? What are the water treatment processes
    used in source water production? Does the water source (i.e.,
    municipal water supply) use chloramine for disinfection?

b.  **STORAGE**

> Is the water stored on site under any condition (i.e. for future use)?
>
> **c. WATER FLOW / DELIVERY**
>
> How does the water flow from the pool(s), through the various (i.e.
> filtration, recirculation, heating, disinfecting) systems back into
> the pool?
>
> Explain the steps in the water flow process. (i.e. the water leaves
> the pool through the main drains -- x% enters through the heating
> system and then goes to the filtration system; y% goes directly
> through the filtration system -- the water then goes through the
> disinfection system---the water then enters the pool through the
> inlets)

Are the pipes labeled with the direction of the water flow?

Are the valves labeled with the direction of on/ off?

Are there any pipes with dead ends? If so, how are they capped off?

Are there any pipes where the water flow is not known?

How is the pool refilled?

> Does the water refilling the pool go through filtration? Disinfection?
> Heating? Recirculation? Other?

**Recirculation**

Fill in the number or description of the following and indicate their
locations on the diagram(s).
