Measuring Turbidity

Turbidity suspended and colloidal matter Caused by such as clay, silt, organic and inorganic matter, and microscopic organisms.

Turbidity should not be confused with color since darkly colored water can still be clear and not turbid. Turbid water may be the result of soil erosion, urban runoff, algal blooms and bottom sediment disturbances, which can be caused by boat traffic and abundant bottom feeding fi sh.

Temperature Aquatic animals (e. g. stream insects, trout and salmon) are sensitive to changes in water temperature and require a certain temperature range to survive and thrive. If water temperature is outside that range for a long time, organisms can be stressed and die.

Temperature also affects the amount of oxygen Cold water holds more oxygen than warm water, and all can hold. animals need oxygen to survive. water

Dissolved oxygen Dissolved Oxygen (DO) is important to the health aquatic ecosystems. All aquatic animals need oxygen to survive. Natural waters with consistently high dissolved oxygen levels are most likely healthy and stable environments, and are capable of supporting a diversity of aquatic organisms.

Dissolved oxygen Cold or hot water contains more dissolved oxygen?

Dissolved oxygen Ans: Cold water For example, water at 28°C will be 100% saturated with 8 ppm dissolved oxygen. However, water at 8°C can hold up to 12 ppm of oxygen before it is 100% saturated. High levels of bacteria or large amounts of rotting plants can cause the % saturation to decrease. This can cause large fluctuations in dissolved oxygen levels throughout the day, which can affect the ability of plants and animals to thrive.

p. H is a measurement of the acidic or basic quality of water. The p. H scale ranges from a value of 0 (very acidic) to 14 (very basic), with 7 being neutral. Most aquatic animals prefer a range of 6. 5 to 8. 0.

p. H They are adapted to a specific p. H level and may die, stop reproducing or move away if the p. H of the water varies beyond this range. Low p. H can also allow toxic compounds to become more available to aquatic plants and animals. This can produce conditions that hurt aquatic life. p. H can be affected by acid rain, wastewater discharges, drainage from mines and the type of rock naturally found in the area.
