Frequently asked questions

What is stagnant water?


Stagnant water is standing water that has been sitting without moving for a significant amount of time.




Can Clean Water Pro implement the recommendations they make?


Clean Water Pro is ready to implement all the recommendations they make.




Should I start with a remediation plan without conducting a proper assessment?


We do not recommend starting with remediation solutions until you know the exact stage your water body is in.




How much is an assessment and what would it provide my committee or municipal board?


Please contact us for pricing information. You will receive a comprehensive report including a chemical and physical analysis of the water in question, as well as three or more recommendations on how to remediate your pond or lake.




Can Clean Water Pro come to my municipality and precisely assess my lake or pond?


Clean Water Pro is available to conduct a precise assessment of your lake or pond.




If I wanted to know the precise condition of my lake or pond, what would be the first step?


If you have completed your 'do it yourself' assessment your next step would be to have Clean Water Pro conduct a thorough assessment.




When should I call Clean Water Pro for help with my pond or lake (body of water)?


You can call Clean Water Pro anytime to ask questions. Clean Water Pro staff will always recommend you start with a do it yourself assessment – refer to question #3 "How do I know I have stagnant water?"




What treatments are typically used to remediate stagnant water?


Treatments used to remediate stagnant water include: ● Aeration. We recommend fine bubble aeration over course bubble aeration. Fine bubble aeration is less costly to operate and much quieter.
● Water or pond friendly bacteria.
● Pond dye. This is not always recommended and would depend on the outcomes desired as well as the type of water system involved.
● Ultra sound waves are used to stop algae growth.
● We often make several recommendations to cabin or home owners on things they can do to slow down the deterioration of their lakes or ponds.




How do I know I have stagnant water?


You know you have stagnant water when you can answer yes to most of these questions: ● Is the lake water murky or hard to see through? ● Do you have floor muck at the shoreline? If so, how far does the floor muck go out from the shoreline? ● Do you have aquatic weeds growing near the shoreline? If so, how excessive are they? Are they spotty, along the entire shoreline, or widespread throughout large portions of the lake/pond? ● Do you see algae blooms? If so, do you see them periodically, in the summer and fall, or all season long? ● Do you see cyanobacteria (often referred to as blue/green algae)? ● Has your lake/pond suffered any fish kills? If so, did the kills occur in the summer, the winter, or both? ●Do you know if your pond or lake has a high phosphorus level?




Why should I care about stagnant water near my home or cottage?


Stagnant water is characterized by having low oxygen levels. This makes it unsafe for consumption by humans & livestock and hazardous to life that normally exists in the water including fish. Perfectly undisturbed water is an adequate breeding ground for mosquitos and the low oxygen content makes it favorable for algae blooms. Cyanobacteria algae blooms can be dangerous to swimmers. New data indicates even low levels of ingested cyanobacteria can be deleterious to a person’s health. Due to the low oxygen levels in stagnating water, living organisms that normally would survive and thrive in the water don’t and instead they die and rot. Rotted organic material in stagnating water creates a foul odor. Eventually rotting organic material sinks to bottom of the pond or lake and re-exists as “floor muck”. Excessive floor muck becomes a haven for another pest, aquatic weeds.
