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 |
heavy metals | item found in large scale fish deaths to anailze for possible toficants. |
Dissolved Oxygen | the amount of elemental oxygen in solutions under exsisting at most atmopheric pressure and tempeture |
Eflunent | Water discharged from a rearing, facility treatment plant or industury |
Turbitty | presence of suspender or colloidal matter or planktonic organisms that reduces light penetration of water |
colormetric | determining the quantity of a substance by the mesaurment of a lign |
conductane | the ability og a substance to allow the passage of electircal current |
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 |

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. |
