|
What is pH |
The intensity of acids or bases |
|
|
|
How is pH balance measured? |
On a scale of 0 to 14. 0 is strong acid, 14 is strong base... Seven is neutral |
|
|
|
What is turbidity? |
The amount of particles in water... That is correlated with disease |
|
|
|
What is federal NTU standard? |
The Federal standard for water quality is 3 NTU. |
|
|
|
How does temperature affect the sustainability of fish? |
Warmer water equals less oxygen... Less oxygen for fish is too consumed |
|
|
|
How are organic chemicals measured? |
Inaugurate (all at once) |
|
|
|
What does the BOD test measure? |
The amount of organic pollution. |
|
|
|
What is dissolved oxygen? |
Oxygen in the water that is available to be used for other things. |
Ice cube. |
|
|
At what level is water saturated with oxygen? |
12 to 13 mg per liter |
|
|
|
What amount of milligrams per liter do most fish need of dissolved oxygen? |
7 to 8 mg per liter |
|
|
|
What happens to an aerated wastewater? |
Unaerited waste water depletes oxygen |
|
|
|
What's the average oxygen that we want are drinking water to be? |
2 to 3 mg per liter |
|
|
|
What are suspended solid examples? |
Silk, clay, bacteria |
|
|
|
How many milligrams per liter for drinking water do you want a suspended solids? |
0 mg per liter |
|
|
|
What are dissolved solids? |
100 to 150 mg per liter substances small enough to pass through a filter |
|
|
|
Can dissolve solids be good for water quality? |
Yes. Water without minerals is generally speaking flat |
|
|
|
What are some good dissolved solids that you can get in water? |
Calcium, sugars, mainly dissolved minerals. |
|
|
|
How many milligrams per liter of suspended solids do you want in treated wastewater? |
10 mg per liter |
|
|
|
What is water hardness? |
Water's ability to consume soap. |
|
|
|
What happens when you have low water hardness? |
low water hardness results in corrosion because the minerals in water are small enough that there's enough oxygen to increase the rate of corrosive |
|
|
|
Why is it bad for drains to have too much water hardness? |
Excessive scaling means clogged shower heads from all the extra minerals |
|
|
|
What does fluoride do? |
Prevents up to 65% of cavities and you generally want 7 to 1 mg per liter of fluoride. |
|
|
|
What does chlorine residual do? |
Cleans water, kills germs. Protects against chemicals |
|
|
|
What's the worst case scenario of chlorine? |
Not having problem chlorine in your water drastically increases the amount of deaths to disease. |
|
|
|
How many milligrams per liter of chlorine residual do you want in your drinking water? |
0.2 to 1 mg per liter |
|
|
|
How much chlorine residual do you want in your swimming pools? |
2 mg per liter |
|
|
|
Trichlorome is related to chlorine... True or false? |
False |
|

|
What are some side effects of sulfates? Is it a big concern? |
Temporary diarrhea, no it's not a big concern. |
|
|
|
