3 Ways of Improving Water Quality at your home & office
Risks in Urban Areas
- Poorly treated sewage can be low in dissolved oxygen and high in pollutants like fecal coliform bacteria, nitrates, phosphorus, chemicals etc.
- Runoff from streets carries oil, rubber, heavy metals, and other contaminants.
- Phosphate-rich sewage effluent from the growing human population enters the waterways and thus contaminates drinking water.
- Groundwater can be contaminated from garbage dumps, toxic and chemical waste. Also from areas like leaking fuel storage tanks, and intentional dumping of hazardous substances.
- Air pollution can lead to acid rain, nitrate deposition, and ammonia deposition, which alters the water chemistry of lakes.
- Treated sewage can be high in nitrates.
