Benthic macroinvertebrates definition

Benthic macroinvertebrates means animals which are large enough to be seen by the unaided eye and which can be retained by a U.S. standard No. 30 sieve (28 meshes per inch, 0.595 mm openings), and which live at least part of their life cycle within or upon submerged substrates in a body of water. These animals usually consist of the aquatic life stages of various insects and arthropods, mollusks, leeches and worms.
Benthic macroinvertebrates means bottom dwelling animals without backbones that live at least part of their life cycles within or upon available substrates within a body of water.
Benthic macroinvertebrates means invertebrate animals that are large enough to be seen by the unaided eye, can be retained by a U. S. Standard No. 30 sieve, and live at least part of their life cycles within or upon available substrate in a body of water or water transport system.

  • Diatomaceous earth filtration means a process resulting in substantial particulate removal in which (1) a precoat cake of diatomaceous earth filter media is deposited on a support membrane (septum), and (2) while the water is filtered by passing through the cake on the septum, additional filter media known as body feed is continuously added to the feed water to maintain the permeability of the filter cake.

  • Reference evapotranspiration or “ETo” means a standard measurement of environmental parameters which affect the water use of plants. ETo is given expressed in inches per day, month, or year as represented in Appendix C of these Guidelines, and is an estimate of the evapotranspiration of a large field of four to seven-inch tall, cool-season grass that is well watered. Reference evapotranspiration is used as the basis of determining the Maximum Applied Water Allowances.
