Water in Pittsburgh’s eastern suburbs may have excess levels of total organic carbon (TOC), a measurement of organic contaminants in water.
The Wilkinsburg-Penn Joint Water Authority reported Tuesday that it had violated standards for the removal of TOC — falling below the required ratio.
TOC does not pose a health risk on its own but may influence other measurements of water quality.
As a result, the water authority is increasing the frequency of its water analysis, from quarterly to monthly. It expects to resolve the issue by the fourth quarter of 2014.
