Groundwater treatment update presentation - City of Scottsdale

Just received the following from Vicki Rosen, the EPA's Community Involvement Coordinator for the North Indian Bend Wash (NIBW) Superfund site. It concerns the Central Groundwater Treatment Facility (CGTF) operated by the City of Scottsdale (in other words - *not* the facility that has had all the issues recently, the one operated by Arizona American Water) -

Dear NIBW CIG:

Here's an invitation from the City of Scottsdale regarding the Central 

Groundwater Treatment Facility.  Please feel free to contact Suzanne 

Grendahl directly with any questions.

Vicki


The City of Scottsdale would like to invite you to an 

informal presentation and discussion of the control systems in place at 

the CGTF.  Since the incident in January at the MRTF, we have been 

questioned about whether this could happen at the CGTF.  We hope 

to explain the redundant systems and alarms that are in place at the 

CGTF to address any concerns.  In addition, the City will give 

a brief description of some additional treatment (TDS reduction) 

that will be added to the CGTF over the next two years, unrelated 

to the remedy. The presentation will be held Thursday, March 13, 2008

at 9:30 a.m. at the City of Scottsdale Water Campus (8787 E. Hualapai Drive).

We look forward to seeing you.

Suzanne Grendahl, Water Quality Director

Any questions should be directed to Ms. Grendahl at the above address or to
Vicki at Rosen.Vicki[at]epamail.epa.gov.

Later!
