Turbidity. This is a qualitative assessment of whether the water clear or clouded from suspended particulate matter. pH, DISSOLVED OXYGEN, CONDUCTIVITY, HARDNESS, TOTAL and PHTH ALKALINITY: Record available measurements from these field tests in the specified units of measure (e.g., hardness is recorded in parts per million or ppm.)
Turbidity. 1) When sampling turbidity in the Receiving Water shows a 5 NTU increase in turbidity downstream of the discharge over the Background Level when that level in the Receiving Water is 50 NTU or less.
Turbidity. Not to exceed 1 NTU. Government verification may be determined by means of the finished product manufacturer’s Certificate of Analysis.
Turbidity. The turbidity was measured with a spectrophotometers’ (DR 28000, Xxxx Xxxxx) predetermined turbidity program, which had a detection range of 40-400 FAU. Samples above the detection range were diluted. A sample of Milli-Q water was used as a baseline.
Turbidity. Turbidity is a measurement of the water clarity. Turbidity is caused by sediment entering the water column and in some cases is caused but excessive nutrients causing algal growth. The threshold for turbidity is based on the EPA reference criteria identified in the document titled: Ambient Water Quality Criteria Recommendations Information Supporting the Development of State and Tribal Nutrient Criteria, Rivers and Streams in Nutrient Ecoregion VII. 2000. US Environmental Protection Agency. The values listed are specific to the appropriate sub- ecoregion identified in the document. Specific Conductance Specific conductance is a measure of the drop in voltage caused by the resistance of the water. Each stream tends to have a relatively constant range of conductivity. Significant changes in conductivity can be an indicator that a discharge or some other source of pollution has entered a stream. Nutrients Nutrients are essential for growth. Streams often contain excessive levels of nutrients, which results in additional algae and other plant growth. The main nutrients of concern are phosphorus and nitrogen, and both elements can be found in several forms. Phosphorus can be measured as total phosphorus (TP) or soluble reactive phosphorus (SRP). SRP typically represents the bioavailable form of phosphorus. SRP is also called orthophosphate. Nitrogen can be measured as total nitrogen (TN), Kjeldahl nitrogen (TKN), nitrate+nitrite and ammonia nitrogen. TKN represents the fraction of TN that is unavailable for growth or bound up in organic form, it also includes ammonium. The remaining fractions, nitrate-nitrite and ammonia represent bioavailable forms of nitrogen. Phosphorus and nitrogen in excess amounts can accelerate eutrophication, causing dramatic increases in aquatic plant growth and changes in the types of plants and animals that live in the stream. This, in turn, affects dissolved oxygen, temperature and other indicators. Excess nitrates can cause hypoxia (low levels of dissolved oxygen) and can become toxic to warm-blooded animals at higher concentrations. The threshold values listed for nutrients are based on the EPA reference criteria identified in the document titled: Ambient Water Quality Criteria Recommendations Information Supporting the Development of State and Tribal Nutrient Criteria, Rivers and Streams in Nutrient Ecoregion VII. 2000.

Turbidity. Section 7. BWS shall at any time, allow full access to MCWD in order for the latter to gather water samples at the sampling point located at the meter vault.
Turbidity. The turbidity measurements were considered reliable through most of the experiment, except for the major spike measurement on 16. Mar. and one measurement at 21.21 h on the 4. May during the nychthemeron measurements. The spike measurements were likely caused by some bigger and smaller particles sticking to the turbidity measuring device. During the latter measurement error, all turbidity values in the dataset showed 12.45
Turbidity. It is assumed that turbidity is important as it affects the interaction between introduced fishes and the endemic Colorado River fishes. Because these endemic fishes have evolved under natural conditions of high turbidity, it is concluded that the retention of these highly turbid conditions is an important factor for these endangered fishes. Reduction of turbidity may enable introduced species to gain a competitive edge which could further contribute to the decline of the endangered Colorado River fishes. (p5-6, BO MWCD, March 1998) It is expected that there will be no changes in turbidity, since these non-project water usages are historic.
