Stream biomonitoring assesses the impact of large-scale livestock production

Article Abstract:

Arguments over the long-run impact of large-scale livestock farm operations on streams have led to the development of biomonitoring processes that evaluate variations in macroinvertebrate populations. Such processes must cover years of exhaustive, systematic and consistent work to negate the possible impact of variations due to environmental factors. Sample collection and identification are the main factors that define biomonitoring procedures.

Alternatives for removal of microbial nutrients: control of water quality deterioration in water distribution systems, part 4

Article Abstract:

Evaluation of methods to remove microbial nutrients at a water treatment plant in Normal, IL, showed that tray-type aerators are effective for methane removal in the water distribution system. Seasonal application of breakpoint chlorination has also been established as a cost-effective maintenance technique to minimize chlorine quantity for ammonium ion oxidation.
