Streams, Lakes and Reservoirs Sample Clauses

Streams, Lakes and Reservoirs. The quality of surface water in rivers and streams, lakes, ponds and wetlands is determined by the chemistry of precipitation and by interactions of runoff (surface water) with soil and rock, transported solids (organics, sediments), groundwater, and the atmosphere. Records of key parameters in surface waters are of value in detecting trends in environmental quality. Changes in surface water quality may be quite rapid (e.g. in response to weather variations and flooding). Water samples taken from streams are usually collected at specified intervals of time. Continuous, real-time monitoring systems provide the most complete information, but are restricted to those parameters for which reliable sensors exist. Comprehensive analysis for water- quality monitoring is, however, expensive, and for most diagnostic purposes sample collection and analysis 4-6 times yearly may suffice, with sampling twice yearly for radionuclides and organic chemicals.
