Transcript of Water Quality Parameters

Water Quality History Of Water Pollution After WW2 -> Technology Revolution Dissolved Oxygen, Biochemical Oxygen Demand, Nitrates, and Phosphates Coliform, pH, Clarity/TSS/
Turbidity & Heat -----> Agriculture caused an adoption of chemical fertilizers ----> Population increase = Sewage increase Coliform pH Clarity/TSS/
Turbidity Heat Dissolved Oxygen (D.O) What: A test that is done to determine if there is a contamination in a water source. Ex-Waterborne diseases
Sources: Sewage,poop in water
Effects:No Environmental Impacts, Coliform found in humans can be deadly. Leads to diseases like.. What: it's the power of hydrogen
7 is neutral
> 7 is acidic
<7 is basic
extremes (either too acidic or too basic) is harmful to sensitive organisms Water Quality Act- 1965 ---> Biological Oxygen Demand Nitrates Clean Water Act- 1972 Sources:
Rocks, minerals & CO2: dissolve in water
Many influential factors Effects:
Environmental: loss of biodiversity due to extremes in pH (harmful to sensitive organisms)
Human: none ---> Better water quality! :) Sources: Fertilizers The O2 gas in between H20 molecules Manure,pelets, and dead plants Increase D.O What:
Clarity: how clear the water is
TSS: Total Suspended Solids
Turbidity: how cloudy the water is Aeration
Photosynthesis
Low Temperature Decrease D.O Sources:
soil erosion
living organism:
algae bloom
nutrients
stagnation
eutrophication Stagnant Water
Aerobic Respiration
High Temperature Decomposing Organic Matter If too low D.O = fish suffocate If too high D.O = gas bubble disease (rare) Effects:
Environmental: increased turbidity leads to less photosynthesis; more absorption of sun rays which leads to higher temperature which then leads to a decrease in DO for organisms
Human Health: diseases and heavy metals attach to water particles which then lead to people drinking turbid water THINK COMPOST! Septic Tank Waste aka poop What:
Warmer water, heat, is discharged into waterways Effects Sources:
Point Source: electricity generation plants, manufacturers
Nonpoint Source: more pavement around waterways the more warmer surface runoff, which causes shifts in the water temperature
more turbid water = warmer waters Effects:
Environmental: hold less DO
warmer waters encourage photosynthesis
more decomposition by bacteria
fish kill
Human Health: none
potential harm is if waters with huge amounts of bacteria are not treated before human consumption Sources: Environmental Impacts:
-Causes an algae bloom, too much algae and not
enough photosynthesis so causes fish kill
-limit of reactants which cause a dead zone Any food added to water = increase in BOD
Untreated sewage Human Impacts:
-Blue Baby Syndrome; when its over 10 ppm
-Problem for infants and pregnant women
-Nitrite interferes with oxygen flow of red blood cells Low oxygen conditions may kill fish When oxygen is removed from water when organic matter is consumed by bacteria Phosphates -Limited reactants for water
-Algae bloom which is connected to DO which ends up with kill fish. DYSENTRY Chloera TYPHOID Hepatitis A EVEN DEATH What is it? -Compound that contains nitrogen and water
-Living things need nitrate, can be received by plants and animals
-Breaks down dead things into the nitrate cycle What is it?
-An inorganic chemical, a salt of a phosphoric acid.
-All living things need phosphorus to survive Sources: -Fertilizers
-Decomposing Organic Matter
-Waste
-Detergent Effects: NO HUMAN EFFECTS!! When waste with high BOD is discharged =aerobic bacteria "eat" the food doing aerobic respiration Can mean there is a high amount of sewage in
the water – waterborne diseases

• Natural inputs‐‐ bogs, swamps
• Human inputs‐‐ paper mills, meat‐packing plants
• Nonpoint inputs‐‐ runoff from urban areas Sources of Organic Matter
