Question

Which of the following is an action a Florida farm could take to reduce fecal coliform in nearby water supplies? Decrease the amounts of pesticides sprayed on its crops Decrease the amount of animal waste that reaches the water supply Increase the amount of fertilizers used on its crop fields Get a water filter that traps algae before the water is recycled

Answer 1

Answer:  Decrease the amount of animal waste that reaches the water supply.

A fecal coliform is an anaerobic, rod shaped and gram-negative bacteria. It originates in the intestines of warm blooded organisms. It is released in the fecal matter of humans and animals. This bacterial strain is a chief contaminant of water body. The waterborne diseases associated in humans because of this bacterial strain includes infection of ears, bacterial and viral gastroenteritis, typhoid fever and hepatitis A. The bacterial strain is added to water body by discharge of human sewage, pet animal feces runoff and  agricultural wastes including animal fecal based manure runoff.

Therefore, by decreasing the amount of animal waste that reaches the water supply is an appropriate action that Florida farm could take to reduce fecal caliform in nearby water supplies.

Answer 2

Answer:

Option B,  Decrease the amount of animal waste that reaches the water supply

Explanation:

Fecal coliform are the microorganism that are facultatively anaerobic ( can survive in anaerobic condition) and  originate, grow  and survive in fecal  waste of all warm-blooded animals.

Fecal coliform basically originate from the  intestines of warm-blooded animals and hence found in their excreta.

Thus, all animal waste is a form of fecal and therefore its flow to the water supplies can cause the infection in water. Therefore it must be controlled.

Hence, option B is correct
