KALAMAZOO, Mich. (WOOD) — Kalamazoo city officials were recently issued a water treatment violation by the state of Michigan.
Authorities say the violation didn’t create any immediate health or safety concerns. The city says water customers don’t need to take any action.
Officials say they added phosphate to the water system, which is a chemical found in many foods and helps protect pipes against corrosion.
The state requires systems to be within an acceptable range of phosphate levels.
A public water supply can be out of those ranges nine days in a six-month period, which is called an excursion.
The city had 26 excursion days in the first half of 2018 and 13 days in the second half of 2018 at the point of entry were the phosphate was added to the water.
There were also 20 excursion days in the parchment distribution system.
The city had readings of being outside the range at five out of 16 pumping stations between the first half of 2018. In the second half of the year, three pumps had readings outside the normal range.
