Case Study: Orb-3 Sludge Pellets Test by Lake & Pond Solutions

Organic matter reduction program

Method: grab samples of the substrate from within the ... beach area were taken before, during, and after the test period. Composite sediment samples from 4 to 24" of water were used for this test. Samples were sent to a state certified laboratory, where they were dried at 105C to remove water and weighed, followed by ignition in a muffle furnace at 550C for 2 hours. The remaining weight is mineral content (sand, metals, clay, etc.).

Total Product Used - 24#'s

• 4# per week for the first 4 weeks
• 2# every other week thereafter

Beach area sampled 15'x40'

April 28, 2009 sample: 1.51% of the sample was organic in nature
July 17, 2009 sample: 1.4% of the sample was organic in nature
August 27,2009 sample: 0.9% of the sample was organic in nature

Results: The SCVA pellets [Orb-3 Sludge Pellets] used in the beach area appear to have reduced the overall organic content significantly. Prior to the addition of the product, organic matter composition was 1.68 times greater than the composite at the end of the testing period.
