RAMIRAN <strong>Glossary</strong> <strong>of</strong> <strong>terms</strong> on manure management 2003 50 Water GROUND WATER SURFACE WATER CATCHMENT WATERSHED GROUND WATER TABLE NITRATE LEACHING DISCHARGE STANDARD EFFLUENT VULNERABLE ZONE Water that flows or seeps downward and saturates soil or rock, supplying springs and wells. The upper surface <strong>of</strong> the saturate zone is called the water table. Water that flows in streams and rivers and in natural lakes, in wetlands, and in reservoirs constructed by humans. The area that drains the rainwater falling on it, via streams and rivers, eventually to the sea or into a lake. Separated from the adjacent catchment area by a ridge <strong>of</strong> high land or WATERSHED. The ridge <strong>of</strong> high ground or imaginary border line separating the CATCHMENT areas <strong>of</strong> two distinct river systems. Water level <strong>of</strong> an unconfined aquifer, below which the pore spaces are generally saturated Transport <strong>of</strong> NITRATES (NO 3 ) from soil in soil drainage water to the aqueous environment. Legal limit to be met when introducing an EFFLUENT into water. Liquid e.g. from MANURE or SEWAGE TREATMENT or industrial processes. Often used to describe a liquid discharged into the environment, usually water, with permission and to appropriate standards or conditions. See also SILAGE EFFLUENT. Generally used for "nitrate vulnerable zones" according to the EU nitrate directive 1991, in which nitrate pollution (from agricultural sources) exceeds, or is likely to exceed, the legal limit <strong>of</strong> 50 mgNO 3 /litre. Atmosphere AMMONIA GREENHOUSE GASES (GHG) NITROUS OXIDE NH 3 . A gas derived from urea (uric acid) excreted by LIVESTOCK ( POULTRY) and implicated in ACIDIFICATION and nitrogen enrichment <strong>of</strong> sensitive ecosystems. Gases that contribute to the “green house effect” and global warming. Include carbon dioxide, METHANE and NITROUS OXIDE. N 2 O. A GREENHOUSE GAS derived mainly from the DENITRIFICATION process.

A GREENHOUSE GAS produced during ANAEROBIC FERMENTATION <strong>of</strong> ORGANIC MATTER, especially from enteric FERMENTATION in RUMINANTS and storage <strong>of</strong> LIQUID MANURE. A constituent <strong>of</strong> BIOGAS. Pleasant or unpleasant smell. A chemical or gas that causes ODOUR. Pertaining to ODOUR Apparatus for measuring ODOUR Minimum concentration <strong>of</strong> an ODOUR that 50% <strong>of</strong> a panel <strong>of</strong> people can smell. Any airborne, finely divided solid or liquid matter with an aerodynamic diameter less than or equal to 100 micrometers. PM10: Diameter
