Analysis of Lake Tana

Undergraduate #37
Discipline: Biological Sciences
Subcategory: Pollution/Toxic Substances/Waste

Diamond Crumby - Howard university


The pollution in Lake Tana, Ethiopia, is a problem for the ecosystem, as well as for the local people who use the water for cooking, cleansing, and recreation. Analyzing the pH, conductivity, total dissolved solids, and the content gives a general overview of the health of the lake. To analyze these measures, 25 samples were collected from different areas of the lake, and the 99720 Water Quality Tester Kit was employed to measure aforementioned parameters. The average for pH was 7.38, the average for conductivity was 110 μS/cm, the TDS was 76.3 ppm, and the salt content was 53.96 ppm. Comparing these findings to 2013’s data, results indicated that pollution has decreased. Future research should analyze more samples per location and more parameters to better measure the true health of the lake.
