The PSC then ordered West Virginia American to cancel most of the layoffs and to collect a variety of statistical information to monitor the quality of its service.
Reviews of those statistics have found that West Virginia American has problems with lost water, valve maintenance and meter testing.
Last week West Virginia American argued, unsuccessfully, that the information it was collecting and reporting was "predominantly unrelated to its response to the chemical spill."
But the PSC thought that information could still be useful.
"Considering the potential strain imposed on the WVAWC distribution system in the Kanawha Valley by recent efforts to combat the chemical spill, the commission concludes that further monitoring is reasonable," the PSC wrote.
West Virginia American Water spokeswoman Laura Jordan said the company would abide by the PSC's decision.
