Water Pollution

1. Living and growing in or on and generally requiring water, (see freshwater, marine, brackish).
3. the condition of a liquid when it has taken into solution the maximum possible quantity of a given substance at a given temperature and pressure
4. the uptake of water, other fluids, or dissolved chemicals by a cell or an organism (as tree roots absorb dissolved nutrients in soil).
6. a chemical used to kill nuisance plants. Herbicides can contain pollutants found in runoff.
8. uptake and retention of substances by an organism from its surrounding medium (usually water) and from food.
12. an overflow or inundation that comes from a river or other body of water and causes or threatens damage
13. a natural stream of water of considerable volume

2. the introduction into water of sewage or other foreign matter that will render the water unfit for its intended use.
5. the change by which any substance is converted from a liquid state and carried of in vapor. Compare condensation, sublimation.
7. the process by which solid particles mix molecule by molecule with a liquid and appear to become part of the liquid.
8. the component of a flow regime that represents normal flow conditions between precipitation events. Base flows provide a range of suitable habitat conditions
9. the current beneath the surface that sets seaward or along the beach when waves are breaking on the shore.
10. the condition of water or soil that contains a sufficient amount of acid substances to lower the pH below 7.0.
11. entry of rainwater into a sewer system from sources other than infiltration, such as basement drains, manholes, storm drains, and street washing.
