Key Influences to Water Quality Inflow creeks: sediment, nutrients, etc. Vegetated surfaces: leaves, pesticides, herbicides, fertilizers, grass clippings, feces, etc. Air deposits: dust, seeds, leaves, acid rain, mercury, etc. Stormwater pipes/ditches: salt, sediment, oil & grease, nutrients, metals, etc. Contributing Pollution to a Storm-water pond or natural water body Non-vegetated surfaces: Dust, eroded soil/silt, oil & grease, metals, seeds, etc. Groundwater (springs or water table): fertilizers, salts, pesticides, herbicides, heavy metals, etc. Industrial discharges: silt, sand, alkali, oil, chemical residues, etc.

Effects of High Turbidity on Aquatic Life �Suspended sediment can have severe negative effects on aquatic life �Salmonids � Direct effects on survival, growth rate, immune system � Effects on egg and larval development � Effects on migration and natural movement � Effects on food source abundance �Aquatic Invertebrates � Effects on food sources (algae and other forms of periphyton) � Effects on filter feeding (clogging, reduced growth, death) � Scouring (damage respiratory organs, dislodgement)

Pool and Lagoon Treatment

Bio Clear Pond Treatment Concept

�Passive water treatment for Total Suspended Solids �Easy installation in ditches, creeks, flow channels or man made baffle grid systems �Multiple block types available depending on sediment type an water chemistry �Recommended to send water sample to Clearflow lab for test. �Onsite Jar tests can be conducted �Need flow rate, flow volume, effluent type, TSS value, hydrocarbon level, release point, release parameters 11
