Vedenlaatuarvot, or water quality values, refer to a set of parameters used to assess the suitability of water for various purposes, such as drinking, agriculture, industry, and supporting aquatic ecosystems. These values represent measurements of physical, chemical, and biological characteristics of water.

Key physical parameters include temperature, turbidity, and color. Temperature affects the solubility of gases and the rate of biological and chemical reactions. Turbidity, a measure of water's cloudiness, can indicate the presence of suspended particles, which may affect light penetration and the aesthetic quality of water. Color can be caused by dissolved organic matter or other substances.

Chemical parameters encompass a wide range, including pH, dissolved oxygen, nutrient levels (like nitrogen and phosphorus), and the concentration of various ions and minerals. pH indicates the acidity or alkalinity of water. Dissolved oxygen is crucial for aquatic life. Elevated nutrient levels can lead to eutrophication, causing algal blooms and oxygen depletion. Heavy metals and other contaminants are also monitored for their potential toxicity.

Biological parameters include the presence and abundance of bacteria, algae, and other microorganisms. For drinking water, the absence of pathogenic bacteria is of paramount importance. The overall biological community can also serve as an indicator of ecosystem health.

Water quality values are determined through regular monitoring and testing. These values are often compared against established standards and guidelines set by regulatory bodies to ensure water safety and environmental protection. Deviations from these values can signal pollution, ecological imbalance, or potential health risks.
