CITY OF TOLEDO SAYS ALGAL BLOOM SEASON IS OVER See the info from the City of Toledo about the end of algal bloom season & our drinking water: The 2014 Algal Season is over; Conservation No Longer Needed Light and temperature conditions which produce harmful algal blooms (HAB’s) no longer pose a threat to our city, according to Director Edward A. Moore, City of Toledo Department of Public Utilities. Lake water temperature has dropped to 55 degrees and there have been no detectable levels of toxin even in “raw” water taken directly from Lake Erie since October 4th, 2014. The City of Toledo Division of Water Treatment has been conducting analytical testing for harmful algal bloom toxins every other day using the new sampling and testing protocol instituted by Ohio EPA on August 3rd, 2014. Water has met all standards since the advisory was lifted August 4th, 2014 and testing has shown no detectable levels for the toxin in tap water since August 20th, 2014. The City posted testing results and daily water pumpage to track conservation on its website. Based on analytical data Toledo has provided to the Ohio EPA and surveillance of bloom conditions in Lake Erie from satellite imagery, the Ohio EPA concurs the algal bloom in Lake Erie has dissipated and that Toledo can safely test three days per week. The City will continue reporting sample results to Ohio EPA and use the results and other surveillance data to elevate sampling frequency if bloom conditions change. Toledo elected to exceed testing requirements for microcystin through the end of the algal season to provide an extra measure of security for customers to help rebuild confidence in the safety and quality of its water following the “Do Not Drink” advisory. Water quality monitoring and treatment adjustments at the plant continue to be done 24 hours per day, 365 days a year by licensed chemists aided by information provided through instrumentation installed at the intake crib in Lake Erie and low service pump station.
