A new report by the American Society of Civil Engineers gives Ohio’s drinking water a grade of D +, saying the way the state treats its wastewater, aging underground water lines, and removal of lead pipes all threaten the drinking water system.

By the year 2050, Ohio is expected to experience a 30 percent increase in extreme rainfall events which could further strain water treatment systems and reduce clean water availability during flooding.

The report went on to say that the state needs to do more to remove lead and galvanized pipes.

Stormwater run-off is also a statewide issue.

The report says Ohio water systems need an estimated $16 billion in investment to maintain capacity and meet growing demand.
