Alum Applications | Case Studies and Success Stories

The proper balance of nutrients like phosphorous and nitrogen is vital to the health of your lake or pond. However, high levels of these nutrients can threaten the health and overall aesthetics of the aquatic ecosystem. Our lake and pond management professionals can help control nutrient levels and restore your waterbody through phosphorus-locking technologies like Alum.

Below are case studies highlighting a few of our success stories involving alum applications.
