Alkaline (synonym basic, caustic)
Having the properties of a base, a pH greater than 7. Usually used as an adjective, i.e. "alkaline soil". See Acid, Base, pH

alkaline soil
Any soil that has a pH greater than 7.0. See also - alkalization - saline-alkali soil - sodic soil - soil alkalinity - soil reaction

alkaline (Al-ka-LINE). The condition of water or soil which
contains a sufficient amount of alkali substances to raise the
pH above 7.0.
alkaline phosphatase A group of enzymes that belong to the class known as hydrolases. They are thought to play an important role in the transport of sugars and phosphates in the intestine, bone, kidney and placenta.
An alkaline substance that has a pH that exceeds 7,5.
Bed Load
Sediment particles resting on or near the channel bottom that are pushed or rolled along by the flow of water.
Hard Water- Alkaline water containing dissolved salts that interfere with some industrial processes and prevent soap from sudsing.
Hauler- Garbage collection company that offers complete refuse removal service; many will also collect recyclables.
Some soils are alkaline, when acid rain falls on them the acid becomes neutral. Plants and trees living on these soils are not in any big danger..

0 is the most acidic and 14 is the most alkaline (opposite of acidic). Activated Carbon Activated carbon is a material used for water filtration particularly effective in removing organic contaminants.
numeric value that describes the intensity of the acid or basic (alkaline) conditions of a solution. The pH scale is from 0 to 14, with the neutral point at 7.0. Values lower than 7 indicate the presence of acids and greater than 7.
The water being purified must be alkaline for the aluminium hydroxide reaction to occur. If the water is not buffred to resist acids, lime or soda ash is added to raise the pH.
Chemicals with high pH are alkaline in nature and are refers as alkalis. They form soluble soaps with fatty acids and are used to neutralize acidic solutions.
Alluvial soils
Highly fertile soils washed down by run off from rivers and streams.
The area is characterized by an environment of alkaline soils, low rainfall and humidity, high wind movement, intense sunlight and high evapotranspiration rates.
A device that sprays alkaline water into a chamber where acid gases are present to aid in neutralizing the gas.

Although the oceans will remain alkaline, marine biologists predict that a shift toward greater acidity could threaten the survival of coral reefs and plankton"an essential and fundamental link in the marine food chain.
pH: Measure of acidity. Stands for Òthe negative logarithm of free hydrogen ionsÓ in water. Water of low pH is acidic; high pH is basic, or alkaline.
Point Source: A pipe that discharges effluent into a stream or other body of water.
pH
a logarithmic scale (0-14) that reflects acidity or alkalinity; pH 7 indicates neutrality; acidic solutions have lower pH values; alkaline solutions have higher values ...
pH
The measure of acidity or alkalinity of a chemical solution, from 014. Anything neutral, for example, has a pH of 7. Acids have a pH less than 7, bases (alkaline) greater than 7.
pH: numerical measure of acidity, with a scale of 0 to 14. Neutral is pH 7, values below 7 are acidic, and values above 7 are alkaline.
It is the quantitative expression of the acidity and alkalinity of a solution and has a scale that generally ranges from about 0 to 14. pH 7 is neutral; <7 is acidic; and >7 is alkaline. [Journal of Physical Chemistry B; v102; 1002-4; 1998.
