NORWALK, Ohio (AP) - A northern Ohio city is battling a harmful algal bloom in a reservoir, but city officials say the drinking water remains safe.

Test results released Tuesday for the body of water in Norwalk showed raised levels of microcystin toxin, the Sandusky Register reports (https://bit.ly/1vgYtE6 ). The tests showed 22 parts per billion of the toxin, up from an initial result of 10 parts per billion. The EPA’s limit for recreational use is 6 parts per billion.

Norwalk does not draw drinking water from the Upper Reservoir, but residents are being warned not to let pets drink from it.

Earlier this month, toxins from algae in Lake Erie left about 400,000 people in Toledo without clean tap water for several days.

The algae that leave behind the dangerous toxins each summer are not supposed to peak until September.

Josh Snyder, Norwalk’s public works director, said the city’s treated water has not shown any algal toxins. He said drinking water comes from the Lower Reservoir, which is frequently treated with copper sulfate to keep algal blooms from arising.

The Ohio EPA is working with Norwalk monitor the issue. Snyder said the agency sent someone Tuesday to check on the bloom.
