'Aquahacking' Aims To Improve Water Quality In Lake Erie

When we hear about hacking, it’s usually not a “good news” story. “Aquahacking” is an exception.

To improve water quality in Lake Erie, teams of engineers, software developers and students worked for months on a hacking competition. Erie Hack is billed as the intersection of the environment and the regional economy.  The Cleveland Water Alliance offered up cash and support, and the ideas started flowing. The final nine teams pitched their ideas to a panel of judges.

Thirty separate water systems in Southwestern Pennsylvania violated the federal Safe Drinking Water Act in 2015, according to a new report from the National Resources Defense Council.

On Sunday, the city of Flint, Mich., will no longer be under a federal state of emergency. A new report suggests that lead levels in the city's water are dropping, though researchers still recommend caution because of the health dangers posed by even small amounts of lead.

In 2014, the Pittsburgh Water and Sewer Authority changed the treatment chemical used to prevent the corrosion of lead pipes, which keeps the toxic metal from leaching into drinking water.

The Pennsylvania Department of Environmental Protection said the switch—from soda ash to caustic soda—posed no threat to public health, but the DEP has cited PWSA for not clearing the change with the agency first, as is required by the state's safe drinking water regulations.

The city's water authority got a slap on the wrist Monday from the Wolf administration two years after making a critical change to the chemicals added to Pittsburgh drinking water.

State Department of Environmental Protection Secretary John Quigley said Pittsburgh Water and Sewer Authority should have gotten approval from the state before switching from soda ash to caustic soda for corrosion control.

More than 100 water systems in Pennsylvania have had lead levels above a federal threshold at least once since 2013, according to an Associated Press analysis of the data.
