Question

2 which of the following correctly describes ways water is being polluted? multiple choice factories releasing calcium into surrounding water contributes to water pollution. industrial, agricultural, and untreated residential waste all contribute to water pollution. run - off of carbon from agricultural fields is a major source of water pollution. well oxygenated water released from a waste water treatment plants results in water contamination.

Explanation:

• Calcium is a natural element and its release alone (without being in a harmful form like certain calcium - based pollutants) is not a typical water - pollution cause.
• Industrial waste (contains heavy metals, chemicals), agricultural waste (pesticides, fertilizers), and untreated residential waste (sewage, detergents) are well - known sources of water pollution.
• Run - off from agricultural fields is more likely to contain nutrients (like nitrogen and phosphorus from fertilizers) rather than carbon as a major pollutant.
• Well - oxygenated water from wastewater treatment plants is a sign of proper treatment and not a cause of water contamination.

Answer:

Industrial, agricultural, and untreated residential waste all contribute to water pollution.
