WATER QUALITY
Water quality describes the condition of the water, including chemical, physical, and biological characteristics, usually with respect to its suitability for a particular purpose such as drinking or other uses.
Water quality is measured by several factors, such as the concentration of dissolved oxygen, bacteria levels, the amount of salt (or salinity), or the amount of material suspended in the water (turbidity). In some bodies of water, the concentration of microscopic algae and quantities of pesticides, herbicides, heavy metals, and other contaminants may also be measured to determine water quality.
Although scientific measurements are used to define water quality, it is not a simple thing to say that water is good or that water is bad. So, the determination is typically made relative to the purpose of the water - is it for drinking, irrigation, or to wash a car with or for some other purpose?
Poor water quality can pose a health risk for people as well as properties. Poor water quality can also pose a health risk for ecosystems.

Majority of Dar es Salaam residents depend mostly on ground water for their domestic use because, they are not connected to the city water supply system, or the supply system is not reliable. Due to widespread use of groundwater (shallow and deep wells), the scientific determination of quality of this mass consumed product is essential. In this study the water quality parameters: physical, chemical and biological contaminants on the shallow wells were investigated around Dar es Salaam City. Except for Total Dissolved Solids (TDS) and Total Hardness, other physical parameters tested were within the WHO acceptable range. Levels of phosphate in samples from Temeke district ranges from 0.42 - 1.20 ppm, while samples from Ilala ranges from 0.16 - 0.36. Meanwhile chloride levels in samples from Temeke ranges between 158.40 - 624.14 ppm and Ilala ranges between 142.34 - 359.52ppm. This could be due to human activities such as small industries and unplanned waste dumping sites close to water source. All water samples were contaminated with both Total Coliform (TC) and Fecal Coliform (FC). The highest TC and FC levels were detected in the sample from Vikunai Village in Temeke municipality (2160/100ml and 67/100ml respectively).This was due to proximity of pit latrines and runoff during rainfall because shallow wells are neither covered nor built up above ground level to create barriers against storm water inflow.Generally, water from shallow wells in Dar es Salaam City is bacteriologically and chemically contaminated. The source of contamination is on-site waste disposal and poor hygiene education. It is recommended that water from wells must be treated prior to consumption in order to prevent potential infections. Residents ought to be provided with water quality management education so that they could know how to treat, store and maintain the quality of drinking water.
