Residual chlorine: The available chlorine which remains in solution after the demand has been satisfied. Compare chlorine demand.
Residue: The dry solids remaining after the evaporation of a sample of water or sludge.
Residual Risk: The extent of health risk from air pollutants remaining after application of the Maximum Achievable Control Technology (MACT).
Residual Saturation: Saturation level below which fluid drainage will not occur.
residual chlorine The amount of free and/or available chlorine remaining after a given contact time under specified conditions.
residual disinfectant concentration ["C" in CT calculations] The concentration of disinfectant measured in mg/L in a representative sample of water.
Residuals generated by the treatment of sewage, petroleum refining waste and industrial chemical manufacturing wastewater with activated sludge. See Activated Sludge.
The animal and plant life of a particular region.
The residual north polar cap of Mars is roughly 1,100 kilometers (680 miles) across. In this photograph taken in March 1999 by the Mars Global Surveyor, the light-toned surfaces are residual water ice that remains through the Martian northern summer.

The residual concentration of a hazardous substance in a medium that is determined to be protective of human health and the environment under specified exposure conditions.
A technology that is the whole or part of a treatment train to cleanup hazardous waste sites.
is the amount of total chlorine maintained in treated drinking water as it travels through a distribution system. It can be free chlorine, combined chlorine (chloramines), or a combination of both.
residual chlorine chlorine remaining in water or wastewater at the end of specified contact period as combined or free chlorine. resistance the opposition which a device or material offers to the flow of current; measured in ohms.
Residual reproductive value (RRV) The expected relative contribution of an individual to its population, by reproduction, for all stages of its life cycle subsequent to the present. Resilience The speed with which a community returns to its former state after it has been disturbed.
all gaseous hydrocarbons produced from wells, including wet gas and residual gas remaining after the extraction of condensate from wet gas,
any liquid hydrocarbons other than condensate extracted from wet gas and sold as natural gas liquids for example liquid petroleum gas, and
coal seam gas.
At these high altitudes, the residual atmospheric gases sort into strata according to molecular mass. Thermospheric temperatures increase with altitude due to absorption of highly energetic solar radiation by the small amount of residual oxygen still present.
Many water systems intentionally leave residual disinfection agents in the water after exiting the plant so it travels throughout the distribution system. The most common disinfection method is some form of chlorine such as chlorine gas, sodium hypochlorite, chloramine or chlorine dioxide.
Disinfectant Time: The time it takes water to move from the point of disinfectant application (or the previous point of residual disinfectant measurement) to a point before or at the point where the residual disinfectant is measured.
Fly Ash- Non-combustible residual particles expelled by flue gas.
Fogging- Applying a pesticide by rapidly heating the liquid chemical so that it forms very fine droplets that resemble smoke or fog. Used to destroy mosquitoes, black flies, and similar pests.
Poultry and livestock manure, and residual materials in liquid or solid form generated from the production and marketing of poultry, livestock, furbearing animals, and their products. Also includes grain, vegetable, and fruit harvest residue.
TDS: Total dissolved solids. A quantitative measure of the residual minerals dissolved in water that remain after evaporation of a solution. Usually expressed in milligrams per liter.
TERTIARY TREATMENT: Treatment of wastewater to a level beyond Secondary Treatment but below Potable.
Ultimate disposal The process of returning residuals back to the environment in a form which will have the minimal or reduced negative environmental impacts.
Virion A virus particle. Viral DNA or RNA enclosed in an organic capsule. See virus.

Municipal Solid Waste
Garbage or refuse that is generated by households, commercial establishments, industrial offices or lunchrooms and sludges not regulated as a residual or hazardous waste. This does not include source-separated recyclables.
LCC includes the cost of land acquisition, construction costs, energy costs, the cost to maintain, service and repair the building and its systems, costs of system replacement, financing costs, and residual or salvage value at the end of the building's useful life.
Pollution Residual discharges of emissions to the air or water following application of emission control devices (EPA 1993b). See also environmental release and environmental intervention.
