Toledo Water Quality

Thank you to our citizens and our area partners. Water has been safe every day in 2015—Our water is safe because of the enormous amount of time, energy and planning over many months expended by dedicated people, many of whom are here this morning.  In addition, some 50 million dollars has been spent in 2015 alone making upgrades and improvements here at our water treatment plant. 

Dashboard CLEAR

Our water is safe to drink. Microcystin is not detected in the intake crib in Lake Erie or in the tap water.

We have an advanced warning system for early detection we did not have in August 2014 with buoys and sondes that allows us to implement operational changes prior to the microcystin reaching the Collins Park Water Treatment Plant.

Raw water conditions are being monitored carefully with data collection sondes all located prior to the treatment plant: nearby the intake crib in Lake Erie, in the intake crib and at the Low Service Pump Station.

We will continue to closely monitor water conditions in the intake crib in Lake Erie. The Ohio Environmental Protection Agency, Great Lakes Observing System, plus university research teams, all join Toledo water treatment professionals in monitoring lake water conditions to provide early warning of potential Harmful Algal Blooms that would affect drinking water supplies.

The quality of water at Toledo's intake crib is monitored 24 hours a day every 10 minutes through sondes. Intake water samples are taken at least once a day, with testing of all daily samples timed according to the characteristics of the water. When conditions warrant, testing is increased. Toledo's testing protocol exceeds those recommended by the 2015 Ohio EPA HAB Strategy.

Frequently Asked Questions

Toledo Water Test Results 

Data from Sondes

Currently, there are three water quality Sonde sensors that detect the water temperature, specific conductivity, pH, turbidity, chlorophyll and blue-green algae sponsored by the City of Toledo. There are 18 other Sonde sensors sponsored by partnering agencies, acting as an early warning system. 


Intake Buoy Data

The water treatment industry recognizes the potential harmful effects of HABs and is attempting to close gaps in understanding and detecting HABs.  The Department of Public Utilities, Division of Water Treatment is concerned about the long-term protection of consumers from the potential consequences of algal toxins in drinking water and is pursuing innovative ways of monitoring water quality as related to HABs.
