Clay barriers around the mound serve to reduce the seepage of wastewater to the surrounding ground.
 

Septic tank sand filter   Used in area where soils are unsuitable for conventional drain fields. The wastewater filters from the septic tank to a second tank, which periodically releases the water through a sand filter. The filter is lined with clay or plastic to prevent wastewater leakage, and the filtrate is collected and piped to a disinfection unit.

Terraces   Earth embankments, channels or a combination ridge and channel constructed across the slope of a field to control runoff. They are generally applied where contouring, strip cropping and reduced tillage operations do not offer adequate protection from soil erosion and are most practical on deep soils. By breaking the length of slope into smaller segments and intercepting the flow of runoff, terraces effectively reduce soil erosion and the transport of sediment off-site. In reducing the volume and velocity of runoff, water is retained on the land for moisture conservation.

This area is under the guidance of the Tug Hill Commission. The entire Oneida Lake watershed situated north of the Lake (except the City of Rome) is part of the Tug Hill Region.
 

Turbidity   A water chemistry parameter, caused by suspended materials such as clay, silt, algae, and other materials that cause light to be scattered and absorbed, not transmitted in straight lines through water. It has a major influence on Secchi disk transparency and therefore the clarity of the lake.
 

Turn over   The upper layer cools down in the fall, until the lake reaches uniform temperature. The thermal barrier to mixing is gone and the lake will mix, or turn over, from top to bottom. This process is called fall overturn. In the spring, the ice melts and the lake again becomes one uniform temperature and mixes, called spring overturn.

Unconfined aquifer   An aquifer that contains both an unsaturated and a saturated zone (i.e., an aquifer that is not full of water) and does not have a confining layer at its top.
 

Underground Storage Tank   A tank with at least 10 percent of its volume beneath the ground, including attached pipes.
 

Unsaturated   When referring to soil, any sample that still has the capability to hold more water without experiencing runoff.
 

Upland (geology)   Land at a higher elevation, in general, than the alluvial plain or stream terrace; land above the lowlands along streams.
 

Use impairment   When referring to a lake, a "problem" in the complete functioning of the lake ecosystem.
 

USGS   U.S. Geological Service

Valley fill   In glaciated regions, material deposited in stream valleys by glacial melt water. In nonglaciated regions, alluvium deposited by heavily loaded streams emerging from hills or mountains and spreading sediments onto the lowland as a series of adjacent alluvial fans.
 

VCP   Voluntary Cleanup Program
 

Vegetative cover   A management technique that involves growing grasses, trees or shrubs in areas where slope and soils are particularly vulnerable to erosion and runoff damage. Because permanent protection is provided, it is an effective control for most pollutants, especially sediments.
 

Very poorly drained soil   Soil from which water is removed so slowly that free water remains at or on the surface during the growing season. Unless the soil is artificially drained, most mesophytic crops cannot be grown. Very poorly drained soils are commonly level or depressed and are frequently ponded. Yet, where rainfall is high and nearly continuous, they can have moderate or high slope gradients, as for example is "hillpeats" or "climatic moors."
 

VOC   Volatile Organic Compound
 

Volatile Organic Compounds (VOCs)   A category of volatile organic compounds with relatively high vapor pressures.

Waste   Material that has no original value or no value for the ordinary or main purpose of manufacture or use; damaged or defective articles of manufacture; or superfluous or rejected matter or refuse.
 

Water table   The upper limit of the soil or underlying rock material that is wholly saturated with water.
 

Water table, apparent   A thick zone of free water in the soil. An apparent water table is indicated by the level at which water stands in an uncased borehole after adequate time is allowed for adjustment in the surrounding soil.
 

Water table, artesian   A water table under hydrostatic head, generally beneath an impermeable layer. When this layer is penetrated, the water level rises in an uncased borehole.
 

Water table, perched   A water table standing above an unsaturated zone. In places an upper, or perched, water table is separated from a lower one by a dry zone.
 

Watershed   The area that consists of all the land, streams, rivers, lakes, and other water bodies that contributes water to the lower end of that watershed at its point of discharge.
 

Weathering   All physical and chemical changes produced in rocks or other deposits at or near the earth's surface by atmospheric agents. These changes result in disintegration and decomposition of the material.
 

Weir   A device for measuring or regulating the flow of water.
 

Well drained soil   Soil from which water is removed readily, but not rapidly. It is available to plants throughout most of the growing season, and wetness does not inhibit growth of roots for significant periods during most growing seasons. Well drained soils are commonly medium textured. They are mainly free of mottling
 

Well graded   Refers to a soil or soil material consisting of particles well distributed over a wide range in size or diameter. Such a soil normally can be easily increased in density and bearing properties by compaction. Contrasts with poorly graded soil.
 

Wetland   An area with some open water and much shoreline and emergent vegetation. The water in a wetland may be only a few inches deep.

Zone of aeration   Also called the unsaturated zone. The portion of the subsurface between the water table and the ground surface.
 

Zoning   A method by which local governments can protect natural resources by using regulations to control land use activities. Through zoning, an area is divided into districts. The local government can then establish laws that govern the use of land with these districts.
 

Zoning variances   A method that can be developed in some areas to facilitate unusual landscape features, such as steep hillsides, scenic vista, erosive sites, and natural drainage that may restrict development.
 

Zooplankton   The primary consumers of the lake food web. Small, microscopic animals that drift with the movement of the water.

µg/l   micrograms per liter
