Who discovered that contaminated water from a public pump caused a cholera outbreak in London in 1854?
Florence Nightingale
John Snow
Robert Koch
Louis Pasteur
John Snow traced cases of cholera in London to the contaminated Broad Street pump. His investigation demonstrated that cholera was waterborne, marking a key event in epidemiology.
Which microbe was identified as the cause of cholera in the 19th century?
Vibrio cholerae
Salmonella typhi
Escherichia coli
Bacillus anthracis
Vibrio cholerae was first cultured and identified by Robert Koch as the causative agent of cholera. Recognizing this bacterium clarified how cholera spread through contaminated water sources.
What simple method did people use before modern treatment to make drinking water safer?
Reverse osmosis
Boiling water
UV light treatment
Chlorination
Before chemical disinfection, boiling was a widely used method to kill pathogens in drinking water. People knew reducing microbial load by heat made water safer to consume.
Which contaminant was responsible for the Flint water crisis in 2014?
Lead
Arsenic
Mercury
Chlorine
In Flint, corrosion of aging lead service lines released lead into the drinking water. Elevated lead levels caused severe health issues and prompted widespread water safety measures.
Which chemical was first widely used to disinfect water supplies in the early 20th century?
Fluoride
Chlorine
Iodine
Copper sulfate
Chlorine was first used extensively for disinfection in the early 20th century to eliminate pathogens. Its introduction marked a major advancement in safe drinking water treatment worldwide.
What was the primary contaminant causing Minamata disease in the mid-20th century?
Cadmium
Arsenic
Lead
Methylmercury
Industrial effluent from a chemical factory in Minamata Bay contained methylmercury, which bioaccumulated in fish and shellfish. Consuming contaminated seafood led to severe neurological symptoms known as Minamata disease.
The US Clean Water Act, which set wastewater standards and protected water bodies, was enacted in which year?
1956
1972
1964
1986
The Clean Water Act of 1972 established federal standards for wastewater discharge and water quality in the United States. It represented a major policy response to growing concerns over water pollution.
Biological Oxygen Demand (BOD) is used to measure what aspect of water quality?
The level of radioactive isotopes
The amount of oxygen consumed by microorganisms to decompose organic matter
The concentration of dissolved metals
The amount of sediment in water
Biological oxygen demand measures how much dissolved oxygen microorganisms consume to decompose organic matter. High BOD indicates elevated levels of biodegradable pollution in water.
The "Great Stink" of London in 1858 was caused by high levels of what in the River Thames?
Industrial chemical discharge
Natural algae blooms
Agricultural runoff
Sewage and untreated wastewater
During the Great Stink of 1858, raw sewage was dumped directly into the Thames River, producing a powerful odor. This public health crisis prompted parliamentary action on sewage treatment.
Which engineer designed the London sewer system after the Great Stink?
Edmund Cartwright
Joseph Bazalgette
Thomas Telford
Isambard Kingdom Brunel
Joseph Bazalgette designed and oversaw the construction of an extensive sewer network in Victorian London. His work effectively redirected sewage away from the Thames, alleviating pollution and public health risks.
Eutrophication in lakes often results from excess nutrients. Which nutrient is most commonly responsible?
Phosphate
Lead
Mercury
Sodium
Phosphates from agricultural runoff and detergents fuel excessive algae growth in water bodies. When algae decompose, they deplete dissolved oxygen, causing harm to aquatic life.
Which modern test is commonly used to detect microbial contamination in water samples?
pH measurement
Coliform bacteria test
Conductivity test
Turbidity test
Testing for coliform bacteria, such as E. coli, provides an indicator of fecal contamination and potential pathogens. It remains a standard and rapid test for assessing microbial water quality.
In Flint, Michigan, corrosion control was lacking because which protective treatment was not applied?
Reverse osmosis
Orthophosphate addition
UV sterilization
Chlorination
Orthophosphate coatings inside pipes form a protective barrier that prevents lead leaching into drinking water. In Flint, absence of this corrosion control led to elevated lead exposure.
Which disinfectant alternative to chlorine is increasingly used to reduce harmful byproducts?
Bromine
Silver ions
Ozone
Chloramine
Chloramine, formed by combining chlorine and ammonia, is used as a secondary disinfectant to reduce the formation of harmful trihalomethanes. It offers longer-lasting residual protection with fewer disinfection byproducts.
The phenomenon where heavy metals accumulate in the food chain is known as?
Eutrophication
Sedimentation
Fluoridation
Bioaccumulation
Bioaccumulation refers to the gradual buildup of toxic substances, like heavy metals, in organisms over time. This process magnifies pollutant concentrations at higher levels of the food chain, posing ecological and human health risks.
A watershed study shows nitrate levels spiking in spring following fertilizer application. Which process primarily explains this pattern?
Increased evaporation of water
Mineral precipitation
Runoff carrying nitrate into waterways
Urban sewage discharge
After fertilizer application, rainfall washes soluble nitrates into rivers and streams as agricultural runoff. This seasonal pattern causes nitrate concentrations to peak in water bodies following spring planting.
Compare 19th-century sand filtration and modern activated carbon filtration: which advantage does activated carbon offer?
Raises the pH dramatically
Increases water hardness
Removes organic chemicals and improves taste
Encourages bacterial biofilm growth
Activated carbon filtration adsorbs a wide range of organic chemicals and improves taste and odor, which sand filtration cannot effectively remove. This advancement expanded water treatment capabilities beyond particle removal.
Why were slow sand filters limited for large urban centers despite effective pathogen removal?
They produce harmful chemical byproducts
They cannot remove visible particles
They require large land areas and frequent maintenance
They operate only at high temperatures
Slow sand filters remove pathogens effectively but require large filtration areas and regular scraping to maintain flow. Such land and maintenance demands limited their feasibility in densely populated cities.
Persistent organic pollutants like PCBs resist degradation in water. Which property primarily contributes to this persistence?
Low solubility and chemical stability
High volatility
Radioactivity
Strong acidity
Persistent organic pollutants like PCBs have chemically stable structures and low water solubility, preventing rapid degradation and dispersal. Their lipophilic nature leads to long-term environmental persistence and bioaccumulation.
In analyzing John Snow's cholera map, which critical step demonstrated the link between water source and disease cases?
Testing water pH near residences
Interviewing factory managers
Measuring sewage levels in the Thames
Geographic clustering of deaths around a contaminated pump
John Snow's hand-drawn map revealed that cholera cases clustered around the Broad Street pump location. This spatial evidence directly linked the water source to disease incidence, supporting the waterborne transmission hypothesis.
