Water Quality Monitoring
At the Maru we believe it is important to monitor the quality of Lake Malawi's water and that of the river's entering into it. The more information available, the greater the potential for human interactions with the lake that are sustainable. Read below about some of the abiotic and biotic indicators we collect. To take a look at the data we click on the links to the left to explore each sampling area.
Ph - Ph is a is a numeric scale used to specify the acidity or basicity of an aqueous solution. The cichlid fish species living in Lake Malawi are particularly sensitive to changes in Ph so monitoring it is important.
TDS - TDS (total dissolved solids) is a measurement of the total amount of mobile charged ions, including minerals, salts or metals dissolved in a given volume of water, expressed in units of mg per unit volume of water (mg/L), also referred to as parts per million (ppm). Monitoring TDS is relatively easy and changes in it may indicate the presence of new pollutants in the sampled water which can then be investigated further.
Water Temperature - Monitoring water temperature, measured in degrees celsius, is important because cichlid fish species are very sensitive to temperature flucuations.
MiniSASS - MiniSass (stream assessment scoring system) is a biotic water quality monitoring system developed specifically to be used in remote areas such as Lake Malawi. By monitoring the presence or absence of various water-dwelling vertebrates and invertebrates we can gain a better understanding of a river's water quality.
