A recent edition of the Woodstock City Manager’s Newsletter details the city’s water treatment process.
The newsletter said that most water sources contain corrosive materials that are capable of bringing contaminants from supply pipes. If left unchecked, this can lead to increased amounts of copper, iron and lead in drinking water.
Woodstock's water treatment includes the application of sodium polyphosphate, which acts as a barrier between the water and pipes, and minimizes the chances of unwanted elements and contaminants getting into the water supply.
In addition, water operators also flush out distribution pipes in order to clear them out. According to the newsletter, when this occurs, or when there is a break in the line, the water can be discolored for a brief period of time.
The treatment plants also carry out multiple tests for different factors on a daily basis. The newsletter said that 30 field tests for iron are conducted each month.
Water sources in the U.S. consist of surface sources, such as rivers, lakes and other bodies of water, and underground wells. The source of the water is a factor that determines what level of treatment it needs. The newsletter said groundwater is less likely to come into contact with contaminants.
