Excessive oxygen

Preliminary (WW treatment)

• Screening: Bars catch large items like rags, sticks, and plastic. 

• Grit Removal: Sand, gravel, and other heavy inorganic materials settle out. 

Primary (WW treatment)

Wastewater sits in tanks, allowing heavy solids (sludge) to sink and lighter materials (scum, grease) to rise, which are then removed. 

Secondary (WW treatment)

• Aeration: Air is added to encourage aerobic bacteria to consume organic matter. 

• Clarification: Sludge (bacteria and solids) settles out from the water. 

Tertiary (WW treatment)

• Filtration: Removes remaining suspended particles. 

• Disinfection: Chlorine, UV light, or ozone kills harmful bacteria and viruses. 

• Nutrient Removal: Further treatment for nitrogen/phosphorus if needed. 

After (WW treatment)

• Sludge undergoes digestion (often anaerobic) and dewatering before disposal or reuse (e.g., fertilizer).

Lethal dose

Teratogens

chemicals, ionizing radiation, and viruses that cause or promote birth defects

Malaria

Percholates health effect

Thyroid gland

Safe drinking water act

Sets national standards for safe drinking water

Cadmium, lead, and mercury

Toxic e-waste metals

Resource conservation and recovery act

set federal standards for the treatment, storage and disposal of hazardous waste in the United States.

Polychlorinated biphenyls (PCBs)

carcinogenic synthetic organic compounds that were manufactured in plastics and insulating electrical transformers until 1979, and even though they are no longer manufactured in the United States, they are still present in the environment

Eutrophication

excess nitrates

Acid rain

Sulfuric & Nitric Acids; damages ecosystems (leaches minerals, harms aquatic life).

Bioaccumulation

A substance accumulates in an organism faster than it's lost, increasing its concentration in that individual's tissues over time.

Biomagnification

The concentration of a toxin increases as it moves up trophic levels in a food web.

Anthropocentric

Human focused

Ecocentric

Nature focused

Sick-building syndrome

Headaches/fatigue from indoor air

Carcinogens

agents (physical, chemical, or biological) that can damage DNA and increase cancer risk

Clean water act

requires wetlands to be constructed to mitigate the effect of newly drained wetlands.
