Each day, the city visually inspects the reservoir for algae.
On June 21, the city issued a warning, telling residents to avoid contact with the water at Veterans Memorial Lake Park until further notice.
The safety warning also prohibited pets from swimming in the reservoir.
“As our part of our exceptional and unconditional commitment to public health and safety, the reservoirs are monitored at the highest quality standards by the water department. During this monitoring we have identified that there is an unknown type of algae present,” interim Norwalk Public Works Director Wally Ritchie said at the time. “We are conducting further testing at this time to identify what type of algae it is. As a precautionary measure, we would like to ask citizens to avoid contact with the water and to not let their pets swim in the memorial reservoir until we have done comprehensive treating to eliminate the algae.”
Further testing led to the city lifting those restrictions this week.
“At this time all tests have come back negative and there are no restrictions,” city officials said.
