Suspended Solids

Background

Suspended solids are particles that exist in waterbodies affecting turbitiy, the clarity of a liquid, and water quality. Common suspended solids include bacteria, clay, silt and plant mater. A high presence of suspended solids indicates high turbidity making the water seem cloudier or muddier. Generally, higher turbidity is an indicator of lower water quality, as higher turbidity blocks sunlight for plants, can clog fishes' gills and reduce their ability to fight disease. 

Water sample collection site 

Methodology

Suspended solids from one of the Bridge Park Dr samples (post rainfall) were collected using a coffee filter, and left to dry over a span of a few days. The solids were then collected using a swab and analyzed under a microscope. 

Results and Discussion

Upon analysis under a microscope, the suspended solids from the sample were identified to be a combination of plant matter and sediment; no bacteria or other living organisms were found. The presence of sediment further proves previous notions about the presence of sediment pollution from storm water runoff. The presence of plant matter could also be due to organic matter from stormwater runoff or it could be the result of eutrophication and decomposing plants.
