PUBLIC RIGHT-TO-KNOW: Something In The Water Here In Mesa?

An announcement from the City of Mesa Newsroom yesterday

Mesa residents may notice a slight change in the taste and odor of their water for the next few weeks.

The temporary change is caused by a byproduct of seasonal algae in surface water called geosmin.    
Cyanobacteria: Anabaena solitaria ~ the organism associated with geosmin 

This it what it looks like >

Even at low concentrations, geosmin causes a musty or soil-like taste and odor in the water.

Geosmin is not harmful and the water is safe to drink and use in daily activities.
???

The City of Mesa's Brown Road Water Treatment Plant is using carbon treatment to reduce geosmin in the water distribution system.
Question: Reduce to what level that is safe and how fast does the carbon treatment produce results?
Here's an Info-Graphic with absorption rates >


Mesa's water continues to meet all state and federal drinking water standards.
That may be true, but there are certain potential carcinogens that are not required to be tested for. . .  the monitoring sites the City of Mesa uses may not be in sufficient numbers to do water sample testing nor may they be frequent enough to monitor and detect incidents.
