## Organizational Background

**American Water Works Association Research Foundation**
**In existence since 1965**
**Most active since about 1984**
**AWWARF Charter**
**Related to but separate from AWWA**
**AWWA created in 1881**
**AWWA Charter**
**Perchlorate brought to Foundation’s attention in June 1997**
**California water utilities concerned about impact**
**AWWARF BOT approved limited involvement in June 1997**

## Treatment Project Background

**Variety of treatment methods needed**
**Address concentrations in utility source waters**
**Treat to less than detection limit/4 PPB**

**Notes:**

## Perchlorate Research Program

**Most of 1998 work will be funded from a $2,000,000 Congressional earmark**
**Congressman Jerry Lewis of California was the champion for obtaining this earmark**
**Earmark for treatment-related research **
**Funding to go to East Valley Water District (EVWD)**
**EVWD in turn working with AWWARF to manage the research**

## EVWD/AWWARFIssue Group Meeting

**Held in anticipation of the Congressional earmark **
**Held in fall of 1997, in Ontario, California**
**Issue Group:  Workshop to Develop a Multiyear Research Plan**
**Focused on treatment and analytical methodology research needs**
**Funded by**
**EVWD**
**Main San Gabriel Basin Watermaster**
**Metropolitan Water District of Southern****California**
**San Bernardino Valley Municipal Water District**
**Southern Nevada Water Authority**

## EVWD/AWWARFIssue Group Meeting, continued

**Twenty-seven** **participants   **
**Stakeholders**
**Experts in potential treatment technologies**
**Experts in analytical issues for perchlorate**
**Addressed status of the problem, discussed issues**
**Identified relevant research needs**
**Broke up into small working groups to define individual projects**

## Planned 1998 Activitiesand Schedule

**Five treatment-related projects moving forward**
**Application of Bioreactor Systems to Low-Concentration Perchlorate Contaminated Water**
**Treatability of Perchlorate-Containing Waters****by Reverse Osmosis and Nanofiltration**
**Treatability of Perchlorate Using Ion Exchange Technology**
**Removal of Perchlorate and Bromate in Conventional Ozone/GAC Systems**
**Investigation of Methods for Perchlorate ****Destruction in Aqueous Waste Streams**

**Notes:**

## Planned 1998 Activitiesand Schedule, continued

**Two analytically-related projects advertised**
**Survey the Performance of the California DHS****(Ion Chromatography) Analytical Protocol**
**Short Term Perchlorate Laboratory Issues**
**No proposals received**

Notes

## Planned 1998 Activitiesand Schedule, continued

**Treatment projects have Phased scope**
**Intent for realistic/applied projects**
**Known conditions**
**Phase 1: Laboratory/Bench scale**
**Phase 2: Pilot scale**
**General Phase 2 work in proposals**
**Pilot scale specifics identified end Phase I**
**Phase 2 on Crafton-Redlands Plume - Terms of Congressional earmark**

**Notes:**
Notes

## Planned 1998 Activitiesand Schedule, continued

**Winning proposal by mid-June**
**Contracts completed 4 to 8 weeks after mid-June**
**Probably August/September before work**
**Timetable contingent on EPA grant released to EVWD**
**Many responding teams include both universities and consulting firms**

## AWWARF Process

**During project period the investigator makes periodic reports of project progress to AWWARF and the Project Advisory Committee (PAC)**
**PAC identified for all projects**
**PACs are volunteer technical expert reviewers**
**The PAC provides ongoing peer review on a project from drafting of the RFP through the final report**
**Perchlorate treatment projects will also****be peer reviewed by EVWD**
