Aquatechnex Opens Montana Office

Noxon Reservoir Eurasian Milfoil Treatment

Aquatechnex has expanded operations into the State of Montana starting May 1, 2021.

Montana water ways have been plagued by invasive aquatic weeds such as Eurasian Milfoil and are starting to see episodes of Harmful Algae Blooms (HAB).  Aquatechnex biologists are expert in developing and implementing management programs to restore lakes and river systems impacted by these water quality issues.

Montana Eurasian Milfoil and Montana Flowering Rush infestations can be controlled by programs we develop.  Our team has successfully removed Eurasian Milfoil from plots in the Clark Fork River using ProcellaCOR herbicide technology.  This work was performed in the summer of 2019, and evaluation by the State of Montana in the summer of 2020 found that no milfoil remained in these treatment plots.  This technology is available only through Pro Certified Applicators approved by SePRO Corporation.  More information can be found at https://sepro.com/aquatics/procellacor-product

Many lakes in Montana are experiencing toxic HAB conditions, a map of those waterbodies that have or are experiencing toxic events can be viewed at https://mtdphhs.maps.arcgis.com/apps/MapSeries/index.html?appid=e8ac7302f8cd4d778461d422492a9d7f

Montana Toxic Algae Blooms can be mitigated in a number of ways by our team.  We have application technologies that will remove the threat.  We also have programs that utilize phosphorus precipitation such as Phoslock to mitigate phosphorus pollution that drives these blooms.

Nanobubbles for Lake Restoration and Algae Management

For decades we have known that providing dissolved oxygen to the lower layer of lakes can improve water quality.  Lakes can stratify thermally in the spring and summer months isolating the lower layer from the atmosphere.  When that happens, aerobic bacteria can consume the dissolved oxygen that is trapped there in short order and that causes a number of chemical and biological changes to occur.  The primary method of solving this problem has been aeration.

In the last year Nanobubble generators have burst onto the scene.  These systems pump water from the lake into the generator and return water laced with Nanobubbles to the lake.  Nanobubbles are extremely small and negatively buoyant.  About 2,000 of them are smaller than a grain of sand.  These bubbles disperse through the lake.  As they “bump” into organic material, they attach and burst delivering oxygen.  This action will also cause a hydroxyl radical to form and that chemistry can oxidize algae cells and the toxins they may produce.  This can provide 24/7 algae control and over time supplement other lake management activities.

Nanobubble Algae Management Study at ASU

Another unique feature of this type of control is that you can oxygenate the lower portion of the water column without disrupting the thermal stratification that is occurring.  This can provide refuge for fish in the cooler deeper waters.

Aquatechnex can provide a Nanobubble system sized to your lake.  These can be sold directly to your orgainzation, or they can be part of an overall lake management program we perform for you with a set monthly fee.  For more information please get in touch at tmcnabb@aquatechnex.com

New HAB/Toxic Algae Monitoring and Response System

This buoy measures chlorophyll a and the pigment that is unique to HAB Blue Green Algae and uploads to the Cloud every 15 minutes. We can monitor your lake from our computer or phone and respond

Aquatechnex biologists have deployed the first of many algae monitoring buoys for our clients in Southern California.  This system measures a number of water quality parameters and reports via onboard cellular system every 15 minutes.  Two of the key parameters measured are Chlorophyll a with provides a measure of algae biomass and Phycocyanin which is a pigment that is unique to Blue Green Algae species.  Blue green algae or cyanobacteria are toxin producers that cause significant problems in our nations lakes and reservoirs.

Every day we examine conditions in these lakes remotely.  When we see Chlorophyll a or Phycocyanin levels increase, we mobilize treatment teams to target and control that growth before it becomes a full blown bloom or toxin producing event.  This allows us to be more proactive and responsive in our mission to keep your lakes free from toxin producing conditions.

Phoslock Work Continues to Impress

Free Reactive Phosphorus drops to near below detection

Free Reactive Phosphorus drops to near below detection

Aquatechnex pioneered the use of Phoslock technology to improve water quality in Western US Lake Systems starting in 2010.  We have treated over 20 water bodies with similar results, a dramatic reduction in Phosphorus available in the water column to sustain toxic algae populations.

The latest project in Southern California continues this trend.  Our team has been combating cyanobacteria blooms in this lake for a number of years using conventional treatment technology.  While applying US EPA registered algaecides provided relief, this was more of a reactionary approach to the situation.  The team had to monitor algae levels and target the lake for treatment when cell count and/or species shifts to blue greens indicated the lake was beyond management thresholds.

This May Phoslock was applied following a management plan developed for the lake.  The application took approximately four days to complete.

Sampling results in the months since look extremely promising.  We have noted no problem algae blooms and the algae that is present is beneficial.  Transparency has improved dramatically.  Total phosphorus levels have dropped dramatically and continue to trend down.  The ortho or free reactive phosphorus has seen a dramatic drop.

We will continue to monitor and report on this project as time goes on.
