Locally, the city Round Rock, Texas went from chlorine to chloramine just 2=
-3 months ago. This was posted on their website at http://www.ci.round-rock=
.tx.us/news/ as follows;

Round Rock water conversion
On Monday, March 3, the City will convert its water disinfection process fr=
om chlorine to chloramine. Chloramine is a combination of chlorine and ammo=
nia and is a widely used alternative to free chlorine. During the change pr=
ocess, please note the following:
n The water is safe to drink.
n Customers may notice a change in the taste and odor of the water. This is=
 normal and should diminish after the system is fully converted.
n Dialysis patients and aquarium owners will need to change their filter pr=
ocesses.

How to remove chloramine according to the Water Quality Association at http=
://www.wqa.org/sitelogic.cfm?ID=348 So what is shell-based activation? an=
d how long for the zeolite absorption?
Chloramines can be removed from water with very low flow rates (5 to 10 min=
utes contact time) through shell-base activated carbon, followed by mineral=
 zeolite media for residual ammonia adsorption.

oup, though hard to pinpoint valuable information, and you have to have a p=
assword to get the guts of the info. But they're there.

  cloramines - never heard of em - Is this a better poison theyve found t=
o add to ouw water? Promoted by bottled water peddlers? At the cost of b=
ottled water we could afford O3, or colloidal Ag.

    Will a carbon filter remove chloramines?
    Yes. To be effective, however, it must contain high quality granular ac=
tivated carbon and you must permit sufficient contact time between the wate=
r and the carbon.

    Will letting water sit for a few days cause chloramines to disappear?
    No. Unlike chlorine, which dissipates when water sits for a few days, c=
hloramines may take weeks to disappear.

    Okay, Tom. So how do we remove chloramines?
