Processing Chemical Analysis Samples

  Don't let the words "processing chemical analysis" overwhelm you! It is so easy once you do it a couple of times! You'll be working from memory before you know it! We will be collecting from FOUR different sites for SUMMER SEMESTER 2021 . You can find the addresses and some photos of the sites under the "SITES" tab.  We are currently running SIX chemical tests on the samples. For SUMMER 2021 , we will be testing for the following: Sulfate HR (High Range) Ammonia Nitrogen HR Nitrate-Nitrogen LR (Low Range) Chlorine (FREE/TOTAL/COMBINED) pH Phosphates Each test has it's own set of very to follow instructions. You can find these instructions in the binder in the lab. They are also listed here on the website for your convenience. Check under CHEMICAL ANALYSIS INSTRUCTIONS in the drop down menu on our site to find them digitally! EXAMPLE #1 ~ SULFATE Turn on calorimeter ENTER into testing menu (it should already be highlighted) Use arrow keys to toggle (an...

Project Description

This project will serve the purpose of the collaboration between  Georgia Highlands College  (GHC) and  Lake Allatoona Association  (LAA) to provide research and analysis needed to successfully build an ongoing lake water quality sampling and reporting system. Quantify  Escherichia coli  (E.coli) and  Fecal Coliform  bacteria to assess the water qualities of Lake Allatoona. Quantify various chemical levels in samples collected from Lake Allatoona. Water samples will be collected from  FOUR  different locations for lab analysis for summer semester 2021. Following EPA approved guidelines for quantification of total Fecal Coliform bacteria per 100 ml of water, our testing will continue for the duration of the eight week summer semester.  The success of this project will be determined by diligent reporting of the data. This data can come through the consistent collection and analysis of water samples from the continuous collaborati...

Collecting Microbiology Samples

  Sample Collection/Field Kit E. coli are naturally present in our guts, therefore, we have to avoid any contamination of the samples.  Put on gloves (make sure the glove bag stays closed as much as possible to avoid contaminants). Wipe gloved hands with alcohol. Collect water from 1" below the surface in large bottle and pour into small bottle  (SHAKE VIGOROUSLY)  Label bottles with a sharpie (Please make sure the labels are readable for the  data pe rson) . Once collected, samples are put on ice until the are ready to be processed at the lab. The ice ensures that any bacteria in the sample doesn't grow in the meantime.   **Samples are processed within SIX hours of collection** Rinse large collecting bottle with deionized water for the next site collection (Prevent cross-contamination). Place all dirty gloves and trash in provided paper bag. Keeping the samples cold with icepacks and processing in a timely manner ensures that bacteria don't have time to gr...
