Water Quality

After some research, I discovered that the primary source of my water is the Sacramento-San Joaquin Delta. Originating from the rivers within the Sierra, the water flows into the Sacramento and San Joaquin rivers, eventually finding its way into the Delta. The water is then transported in the Contra Costa Canal. 

The water that comes from the Sacramento-San Joaquin Delta is treated at 6 different water treatment plants. I learned that these plants use a process called conventional treatment to clean and disinfect the water. First, the larger materials, such as dirt, pebbles and debris are screened out. Then the water is mixed with treatment chemicals that cause the smaller particles to clump together and settle to the bottom. The water is then disinfected with ozone, chlorine or chloramines to kill any bacteria. Finally, it goes through sand and carbon filter beds to make it clean and clear. 

After viewing the recent water quality results, I was a little shocked to see some of the substances that were found. Arsenic, mercury, and radon were just a few of the contaminants listed. I like how the Contra Costa Water District provides these annual water quality reports. This allows the public to view the quality of water they are receiving and the level of contaminants that are found. 

In terms of drinking water, the only filtering product I have used is the Brita water filter pitcher which I have purchased from Costco awhile back. It is basically a pitcher with a built in filter that is changed after several months depending on use. According to Brita, 1 water filter can replace 300 standard water bottles, which I think is pretty impressive. I am, however, still guilty of using bottled water from time to time. I try my best to stick to reusable water containers.
