Water Health: Testing and Determining Health of Local Bodies of Water

Christian Samuel Shire, Ryan Seunoy Nisay 

Ponds and rivers represent distinct aquatic ecosystems characterized by significant differences in size, flow, and water quality metrics through pH, salinity, total dissolved solids (TDS), specific gravity, temperature, electric current, and oxidation-reduction potential (ORP). While general metrics for assessing pond health are well-established, regional tolerance ranges can vary from commonly accepted values. This study aimed to evaluate the health of local ponds and rivers by comparing water quality data to standardized ranges and observing temporal changes in key metrics. Selecting three bodies of water in Loudoun County, Virginia (Living, Stagnant, and River), and using an all-in-one water quality tester, we measured pH, salinity, TDS, specific gravity, temperature, electric current, and oxidation-reduction potential (ORP) across three local bodies of water. These findings were compared to the data and results of the National Institutes of Health, the United States Environmental Protection Agency, and Kasco Marine. Results indicated that all three water bodies fell within healthy ranges, supported by evidence of abundant wildlife and stable environmental conditions. No significant pollution or stress-related changes were observed, suggesting that these ecosystems maintain good health over time. This study provides baseline data for local water quality and highlights the stability of these ecosystems under current conditions.
