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.

Is “Bio-Dredging” a thing? Yes it can be

Lakes and ponds are the lowest point in the watershed and over time can fill in with deposits of rich organic sediments.  Over time, these sediments are an accumulation of dead aquatic weed and algae growth, fish and other organisms and become a sink for nutrients that can cycle back to the water column and fuel additional growth degrading water quality.

Removing this organic build up is often required to restore water quality and to add depth to the pond.  Conventional dredging can be problematic in urban settings.  There often is not room to pump dredge spoils in a HOA or golf course pond environment.

Our mapping systems can determine lake sediment composition, the lighter colored areas show organic sediment accumulation

One solution is to enhance the natural processes to digest this organic matter and increase water depth.  This can be accomplished by our biologists using a combination of Nanobubble Technology and the addition of Probiotic natural bacteria cultures.

A nanobubble generator deployed to lake to increase sediment oxygen levels

Dissolved oxygen levels in organic lake sediments is generally very low to zero.  Dissolved Oxygen is key to the success of aerobic digestion of these organic sediments.

Nanobubble generators deliver high levels of dissolved oxygen right to the sediment interface and the interstitial waters within the sediments.  These generators pump water from the lake though the nanobubble generator and inject nanobubble rich water back into the lake.  Nanobubbles are very small, on the molecular level, and they are negatively buoyant and sink to and into the sediment layer throughout the lake.  They then attach and burst delivering dissolved oxygen right into the sediments.

Sediment oxygen levels rise dramatically after installation of nanobubble generator and increase digestion of organic sediments

We install either a temporary or permanent Nanobubble Generator at the lake sized to the volume of the lake

We then apply Naturalake BioSciences MuckBiotics pellets evenly across the targeted area monthly.  MuckBiotics pellets saturate the sediment layer with rare earth stimulants and a broad spectrum of natural aerobic bacterial cultures.  This accelerates the digestion of organic matter

MuckBiotics pellets are then applied monthly to increase the speed of sediment digestion.

We measure the reduction in sediment depths over time to document the recovery of the lake from the impact of accumulated sediments.  This process will not reduce deposition of sand or soils, but can greatly benefit the lake and avoid having to physically dredge organic sediments to restore water depth and lake health.

Our biologists can design a program that meets your needs.  Please reach out if your pond needs remediation of organic sediments.

We also work with conventional dredging equipment when this approach isn’t suitable for your situation.

Good Article on our work at Ketchum Lake

Ketchum Lake has been one of the more prolific algae toxin producing lakes in the state of Washington.  Aquatechnex biologists were brought in to implement an ALUM treatment program that focused on sequestering phosphorus.  This project has been very successful.  For additional information on this project and results go to the County Web Site at http://snohomishcountywa.gov/2451/Lake-Ketchum-Restoration

Gene Williams also presented this work at the Washington Lakes Protective Association meeting in Walla Walla this week with his paper titled “A new life for Lake Ketchum, Restoration of a hyper-Eutrophic Lake”

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.
