Rainfall made sufficiently acidic by atmospheric pollution that causes environmental harm, typically to forests and lakes
Refuse is deposited and then covered with soil.
Daily application of the soil cover prevents
spreading of flies, rats, fire, and paper.
A site for depositing garbage
Wastewater effluent is the final product of all earlier treatment processes, and it can be discharged to a stream, river, bay, lagoon or wetland
Sludge that has been treated to ensure that it can be safely applied to land as a fertilizer or soil amendment
the use of microorganisms for the decontamination of soil or groundwater. usually involves injecting organisms or oxygen into contaminated zones
commonly used bacterialindicator of sanitary quality of foods and water. They are defined as rod-shaped Gram-negativenon-spore forming bacteria which can ferment lactose with the production of acid and gas when incubated at 35-37°C. Coliforms can be found in the aquatic environment, in soil and on vegetation; they are universally present in large numbers in the feces of warm-blooded animals
Field crops are best
Effluent can not be sprayed on fresh produce
The weather phenomenon in which a layer of warm air overlies cooler air near the ground and prevents the rising and dispersion of air pollutants
The distinctive heating effect on the Earth’s surface due to the gases and carbon dioxide in the atmosphere that trap solar radiation and emit infrared radiation
A standard for measuring the amount of solid or liquid matter suspended in the atmosphere, i.e. the amount of particulate matter over 10 micrometers in diameter
matter 2.5 is small stuff that gets deep into lungs.
(Biochemical Oxygen Demand) – ;The amount of dissolved oxygen needed by aerobic biological organisms in a body of water to break down organic material present in a given water sample at certain temperature over a specific time period
its a problem in lakes if oxygen level gets too low.

Deals with point source pollution regulation
Deals with non-point source pollution regulation
Deals with wetland regulation
Non-point water pollution sources
Nonpoint source pollution generally results from land runoff, precipitation, atmospheric deposition, drainage, seepage or hydrologic modification. The term “nonpoint source” is defined to mean any source of water pollution that does not meet the legal definition of “point source” in section 502(14) of the Clean Water Act.
Non-point water pollutants: sources are… city streets, rural homes, cropland, animal feedlot.
Point source water pollution
: Comes from point sources that are specific, large, identifiable discharge outlets –wastewater treatment plants, industrial or factory drains. Confined animal feeding operations (CAFO’s) of more than 1000 animal units.
Point sources water pollutants
1. Infectious agents
a. Bacterial diseases
Typhoid, Cholera, Salmonellosis
b. Viral disease – hepatitis
c. Protozoa – amoebic dysentery
d. Parasites – giardia
2. Inorganic chemicals
b. Nutrients – N and P
c. Heavy metals – Pb, Hg, Zn, Cu, Cd.
3. Organic chemicals
a. Petroleum wastes and spills
c. Carcinogens and mutagens
4. BOD – “Biochemical oxygen demand”
Decomposable organic residues
5. Grit – Sand, silt, and clay
A. Agricultural BMPs

D. Urban area BMPs
Road salt disposal, street sweeping,
pet waste disposal
E. Mining BMPs
Drainage retentions basins
Indicator organism in water
used to measure such things as potential fecal contamination of environmental samples. The presence of coliform bacteria, such as E. coli, in surface water is a common indicator of fecal contamination.
