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”

The Canyon Lake Newspaper has published a good article on our treatment program to sequester phosphorus and help improve water quality.  The article can be viewed at http://fridayflyer.com/2014/04/18/alum-treatments-proving-effective-in-lake-clarity

 

 

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.
