Key Influences to Water Quality

Inflow creeks: sediment, nutrients, etc.

Air deposits: dust, seeds, leaves, acid rain, mercury, etc.

Stormwater pipes/ditches:salt, sediment,oil & grease, nutrients,

metals, etc.

Groundwater (springs or water table):fertilizers, salts, pesticides, herbicides, heavy metals, etc.

Non-vegetated surfaces: Dust, eroded soil/silt, oil & grease, metals, seeds, etc.

Contributing Pollution to a Storm-water pond or

natural water body

Vegetated surfaces: leaves, pesticides, herbicides, fertilizers, grass clippings, feces, etc.

Industrial discharges:silt, sand, alkali, oil, chemical residues, etc.

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)

Effects of High Turbidity on Aquatic Life

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
