Detroit Reservoir has algal blooms each year. Why is it that bad this year?

"Every flower is different," said Goeres-Priest.

She said it depends, among other things, on how high the toxins are in the watershed and whether toxins are being formed all the way down to the water treatment plant.

"It's hard to say why this year is different from last year," said Goeres-Priest. "We only know that this is the case because of the sample results."

Three toxic blooms were identified at locations around Detroit Lake – on the blowout arm, on the Heater Creek Arm, and near the dam. That's more than in the past.

The flowering in blowout arm had a particularly high concentration of toxins, officials said. A liver toxin called "microcystin" was tested on May 23 at 48.21 parts per billion at this location. A health consultation is triggered when the values ​​are only 4 parts per billion.

What is recommended for expectant or nursing mothers?

Farrer said he has no good data on whether toxins can be transmitted from a nursing mother to her baby. But officials definitely do not want mothers to drink the water – they should be bottled with water.

He said breastfeeding in this case was preferable to making formula with tap water.

Which cities outside Salem are affected by drinking water restrictions?

Stayton and Turner agree with Salem's Water Consulting.

"We're testing our water," said Keith Campbell, Stayton's City Manager. "I do not know if it's as common as Salem, but our tests did not show anything."

Still, "We're just following the advisories with the city of Salem," he said.

David Sawyer, Turner's city administrator, said Salem officials contacted his city last week and told them about the concern.

"All the water that comes to Salem, basically, we use those lines when they come through the canyon, it's the same system," Sawyer said. "Because of the size of our distribution system, we test for E. coli, and we test for chlorine and things like that, just to make sure."

What about restaurants?

Farrer said that restaurants that use city water should not use the water to serve customers.

Health officials also advise against using the water for cooking and washing food, he said.

Why is it safe to bathe and wash dishes with water?

City officials said the water was fine for cleaning, bathing, and washing dishes, and for cleaning laundry, handwashing, and toilet flushing.

"Infants and toddlers under the age of six should, however, be supervised during bathing and during other tap water activities to prevent accidental ingestion of water," the consulting states said.

Farrer said that these toxins are not absorbed through the skin and the only way for them to get in people is when they are swallowed.

Healing Officials recommend that children who are being bathed be supervised to ensure that they do not drink the water, Farrer said.

Even so, a small amount of consumption will not be detrimental, like the amount you swallow when you wash your face, or that bit of water that comes into your mouth when you shower,
