Tag: TSS

Day 3 @CAAE

The first thing we did was calibrate the scale, weigh the washed filter sheets, and weigh the baked filtered sheets with TSS on it.

This is the final compiled data after baking and weighing filter sheets with TSS from water taken from Falls Lake and Lake Wheeler, which we tested on Tuesday, May 28th.

We had 4 more samples of water from Lake wheeler that came in yesterday and we tested today. This test includes one daily dry filter, one filter solely filtered with water, one lab duplicate, and the 4 standard samples.

Taking a break to enter the data from Tuesday’s filtering, we went into Joy-Lynn’s cubical and she showed me her super cool ergonomic chair!

After lunch, endures the long process of writing down the layout of both stormwater and Neuse River SRP (orthophosphate) samples and typing them in for the auto-analyzer to run.

Day 1 @CAAE

Welcome to the NC State Center For Applied Aquatic Ecology!

Here are some machines that I learned how to use today as well as some important processes to remember:

Testing template for silica in water and seawater

High purity water machine

quAAtro machine flushing and stabilizing before analyzing [the quAAtro machine is also referred to as the Continuous-Flow Injection Auto-Analyzer] (see attached link below)

32 silica samples taken from falls lake for a student working on her PhD

Testing for total suspended solids from falls lake with labeled water samples and glass microfiber filters

Data recorded from the filtering- includes filter paper number, filter paper weight in milligrams, volume of water added, and sample name. The filter and residue weight will be measured Thursday after the filter paper is dried in the oven at 104.1°C. The samples included 3 field duplicates usually meaning they were collected using the same collecting methods and for every ten samples, we did a lab duplicate to see if our filtering methods yielded consistent results. Gathering all the data from filtering took 3 hours, which did not include weighing 30 glass microfiber filters before which took another full hour!

These are the glass microfiber filters after filtering the lake samples
