How can our drinking water system be positively affected by smart city planning? North Carolina’s population density is increasing, and therefore more water is needed for our citizens. The way urban areas are developed can greatly affect the water supply. Finding ways to reduce storm water run-off into waterways, reconnecting tributaries to rivers, and utilizing bioremediation are all ways to help maintain the resilience of our drinking water system.

Adhesion = When water clings to another surface due to the surface tension of the molecules. In the water cycle, rain clings to the surface of leaves, branches, and grass.y
Biome = A large naturally occurring community of flora and fauna occupying a major habitat
Bioremediation = The use of living organisms, such as bacteria, fungi, or green plant to break down or remove pollutants from a contaminated site.
Biosphere = The regions of the surface, atmosphere, and hydrosphere of the earth occupied by living organisms.
Community = A group of organisms living in the same place or having a particular characteristic in common.
Condensation = The process when water vapor as a gas cools and changes to the liquid state.
Consumer - Single-celled organisms obtain energy by eating the producers, tiny particles of leaves, or even each other.
Culverts = A tunnel carrying a stream or open drain under a road, sidewalk, or other paved surface.
Detritus = Waste or debris of any kind such as gravel, sand, silt, or other material produced by erosion or organic matter produced by the decomposition of organisms.
Ecosystem = A group of interacting organisms and their physical environment.
Estuaries = The wide lower course of a river where it flows into the ocean. The water in estuaries is a mixture of fresh water and salt water.
Evaporation = The process when liquid water warms and changes to the gaseous state
Filterers = Benthic macroinvertebrates that strain very small food particles suspended in the water.
Food web = a system of interlocking and interdependent food chains where a hierarchical series of organisms each dependent on the next as a source of food.
Gatherers = Benthic macroinvertebrates that use mouths or forelegs to pick up organic matter off the bottom of a river or stream.
Headwaters = A tributary stream of a river that is narrow and shallow located the furthest from the mouth of the river.
Ions = Atoms or molecules with a net electric charge due to the loss or gain of one or more electrons.
Microscopic Organisms = Tiny life forms, often consisting of a single cell, that can only be seen using a microscopic and very sensitive to change.

Population = All of the inhabitants of an area.
Precipitation = Any form of water (rain, snow, sleet, or hail) that falls to the ground.

Resilience = The capacity of a system to absorb distress or disturbance and recover quickly.
Retention Pond = A low lying area that is designed to temporarily hold a set amount of water while slowly draining to another location.
River = A large natural stream of water flowing in a channel to the sea, a lake, or another such stream.
