| 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 |

| 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. |
