Columbus Water Works' Response to the Water Crisis in Flint Michigan
The City of Flint, Michigan has been in the news recently regarding lead contamination in their drinking water. In response to customer concerns, Columbus Water Works (CWW) is committed to providing you with timely and accurate information, particularly in regards to the safety and quality of our water.

According to published reports, there were two major factors which contributed to the crisis in Flint Michigan:
  • the lack of adequate corrosion control treatment, and;
  • the presence of lead service lines and partial lead service lines within the water distribution system
As per CWW, in regards to the quality of drinking water in Columbus, our customers can rest assured that all is well.  Unlike the City of Flint, there are no lead service lines in the CWW system and corrosion control is effective and monitored closely.  As a component of our corrosion control inspection and treatment program, CWW’s compliance with the EPA’s lead and copper rule has remained within regulatory limits since analysis began in 1992.  Effective corrosion control is essential for good water quality and CWW balances the water chemistry consistently around the clock three times more often than standard practice. Additionally, CWW performs testing quarterly to measure metal corrosion rates to confirm that corrosion control is at the optimum level.

As reported in CWW’s most recent Annual Water Quality Report mailed to all customers, water is tested at the customer’s tap and these tests show that the water is safe and meets EPA’s lead and copper regulations. The Water Quality Report also contains general information about lead in drinking water.  To view the 2014 Water Quality Report, click here.
