pH one of the most common water tests - is a measure of hydrogen ions in the water
Organic matter consists of living, its excretions, and decomposing material.
tiremetric added to a known or specific vloume of a sample in the presence of an indicator. The indicator producse a color change indicating that the titartion is complete.
heat capicity the water is very high making it resistent to changes in tempeture.
fertilization addition of nutrients to a pond to stimulate natural food production
water hardness measure of the total concentration of primarly calcium and magnesium expressed in milligrams per liter of equivalent calcium carbonate
salinity the measure of he total concentration of all dissolved ions in water
salts substances hat dissolve readily in water to form simple ions.
saturation in solutions the maximum amount of a substance that can be dissolved in a liquid without it being percipitated or released into air.
Beer's law the light passing through a colored liquid decreases as the concentration of the substance dissolved in the liquid increases
Anions negitive ions

saturatrin the maximum amount of a substance that can be dissolved.
Alkaline basic, pH greater than 7
Anaerobic reffering to a process or organism not requiring oxygen
aeraton the mixing of air and water by wind
ions elemetal forms or groups that carry an electrical charge in solution.
cations possitive ions
Liming water with a stable and low pH.
Thermal stress a shock that can occur when tempeture changes more than 2 degrees to 3 degrees Fahrenheit in 24 hours.
Solubility the degree to which a substance can be dissolved in a liquid
Buffers Any substance in a solution that tends to resist pH change by neutralizing any added acid or alkali.
Aeration the mixing of air and water by wind action or by air forced water.
Titrant The reagent or standered solution used in titraition.
Settling pond area where the solids settle to the bottom and the top water is released into the environment or a stream.
Hydroponics the growing of land (field) crops with their roots dangling in nutrified water.
