Examples of Nephelometric in a sentence

  • During the 9 November 2021 inspection, Board staff observed that large portions of the Project had erosion control BMPs installed; however, road cuts and other disturbed soil areas did not have erosion control BMPs. Also, sediment controls that were installed were overwhelmed and a storm water discharge with a turbidity of 724 Nephelometric Turbidity Units (NTU) into Olympia Creek was observed.

  • If an increase in turbidity, as a result from contractors operations, exceeds 10 Nephelometric Turbidimeter Units (NTU’s) for a period exceeding 30 minutes, the contractor shall cease operations.

  • CDFW surveys measured specific conductance (μS/cm), temperature (˚C), and turbidity (Nephelometric Turbidity Units; NTU) of surface water at each station, and specific conductance data were converted to salinity.

  • If there continues to be circulation of sand, silt, mud, or water with a turbidity in excess of 25 Nephelometric Turbidity Units (NTU) to the surface from the section of screen being cleaned, additional swabbing and pumping shall be performed until the section is cleaned of such material.

  • SLT and its contractors shall ensure to the extent practicable that the turbidity (as measured in Nephelometric Turbidity Units [NTUs]) shall not exceed background levels by more than the 10 percent outside the Project Boundary when background levels are greater than or equal to 50 NTU, to the extent practicable.

  • All compensation under this Agreement shall be subject to customary income tax withholding and withholding of such other employment taxes as are imposed by law.

  • These objectives require that project discharge cannot exceed 1 Nephelometric Turbidity Unit (NTU) when natural turbidity is between 0 and 5 NTUs, 20 percent of natural turbidity levels when natural turbidity is between 5 and 50 NTUs, 10 NTUs when natural turbidity is between 50 and 100 NTUs, or 10 percent when natural turbidity is greater than 100 NTUs. A biological Construction contractor (implementation) During the construction period.

  • Nephelometric turbidity analyses were also conducted (EPA 1983b) for all subsamples during the treatability tests.

  • If turbidity levels immediately downstream of the project rise to more than 20 NTUs (Nephelometric Turbidity Units) above the upstream (baseline) turbidity levels, all construction shall be halted and all erosion and sediment control devices shall be thoroughly inspected for proper function, or shall be replaced with new devices to prevent additional sediment discharge into streams.

  • Turbidity is a measure of water transparency and is expressed in Nephelometric Turbidity Units (NTUs).
