Below you will find answers to the questions we get asked the most about treatment notices, water use restrictions, and the products we use. You’ll also find links to documents and information frequently requested.

FAQ

Swimming Restrictions

When Can I Go Swimming?
Most products applied to your water body require a 24-hour swimming restriction. The date marked in the swimming restriction section on the treatment notice is the date you can enter the water again. Please locate and read your treatment notice and follow all restrictions.
Some products do not have swimming restrictions. If there is no date marked, there is no restriction for that water use. You are able to swim as usual.
For your safety, residents should stay out of the water and keep their pets out of the water until our field technicians have completed your treatment and left the water body.
Our crews may treat your water body at any hour of the day, so it may be difficult for a resident to know when they can swim. For example, if we finish a treatment at 6 PM on a Monday, you should not go swimming at 8 AM on Tuesday. To ensure the safety of residents, our signs would say “Do not swim until Wednesday” to be certain at least 24 hours have passed since the treatment.

If you find yourself in this situation, do not panic. Your first step should be to get out of the water and take a shower to wash off the treated water. Monitor for any symptoms that may be due to contact with the treatment products. If symptoms are present, consult the product Label and Safety Data Sheet. All Labels and Safety Data Sheets are available here on our website.

If you find yourself in this situation, do not panic. Your first step should be to get your pet out of the water and rinse them to wash off the treated water. Provide fresh water for your pet to drink and monitor for any symptoms that may be due to contact with the treatment products. If symptoms are present, consult the product Label and Safety Data Sheet. All Labels and Safety Data Sheets are available here on our website.

The safest measure is to avoid swimming for the duration of the posted restriction. However, during a single treatment, we will not treat the entire water body, so swimming may occur in the untreated areas. You should stay more than 100 feet from any treatment area. If you are unsure of the treatment area, please ask the crew while they are on-site or call our office.

Irrigation Restrictions

There Is No Date Marked In The Irrigation Restriction Section. When Can I Use The Water Again For Irrigation?
Some products do not have irrigation restrictions. If there is no date written, there is no restriction for that water use. You are able to use the water as usual for irrigation.
The date marked for “Do not use treated water irrigate grasses until” is the date when you may resume irrigation with treated water.
The date marked for “Do not use treated water to irrigate flowers or ornamental plants until” is the date when you may resume irrigation with treated water.
The date marked for “Do not use treated water to irrigate vegetables or food crops until” is the date when you may resume irrigation with treated water.

Drinking Water

My Dog Drank The Treated Water, What Should I Do?

If you find yourself in this situation, do not panic. Your first step should be to get your pet out of the water and rinse them to wash off any treated lake water. Provide fresh water for your pet to drink and monitor for any symptoms that may be due to contact with the treatment products. If symptoms are present, consult the product Label and Safety Data Sheet. All Labels and Safety Data Sheets are available here on our website.

Fishing

Is It Safe For Me To Go Fishing In Treated Water?
Yes. There are no restrictions for fishing with any products we use. If you are fishing in a treatment area, it is a good idea to wash your hands if you come in contact with the water.
Yes. There are no restrictions for consuming fish with any of the products we use.

Posting

Why Do I Have A Sign Posted At My House?
The EGLE permit requires we post a treatment notification sign at every home along a treatment area and any home within 100 feet of a treatment area. The sign includes the date of treatment, products applied, and applicable water use restrictions.
You may remove the sign after the longest restriction expires. Please follow all restrictions for the durations indicated.
The EGLE permit requires we post a treatment notification sign between your home and water body. We may staple the sign to a tree or dock post. We may also use a small plastic stake.

Posting Questions and Information

Posting Requirements

Every resident on the waterbody that undergoes treatment must receive a notification of when the water was treated, with what products, and any water use restrictions related to those products. The Sign must be placed between the residence and the shoreline, be a minimum of 12 inches above the ground, and be posted in a location that is visible.

7-Day Treatment Notice

Anyone in immediate proximity to the waterbody will receive a notice detailing all products that may be used for the upcoming season and their restrictions. This 7-45 Day Treatment Notification will be delivered to the customer at least 7 days prior to the first treatment.

Treatment Notifications

Customer communication is of utmost importance. After each application, a director reviews the treatment with the applicator. A Treatment Notice is then emailed to whoever is responsible for organizing the treatment. This allows both our team and the customer to be on the same page throughout the entire season and to share any notes or recommendations if needed.
