VikaD [51]

Answer and Explanation:

To determine the overall health of the alligator pond, Mr. Ortiz should carry out the following tests:

  • <u>pH level test</u>

pH is extremely important in this type of research as a reduction of pH could lead to a higher availability of toxic metals that may be absorbed by aquatic organisms such as alligators and fish species.

<em>pH is acceptable in a range of 6.5 to 8.2.</em>

  • <u>Nitrates and Ammonia (NH3) levels</u>

Oversaturation of nitrates and ammonia could lead to the death of organisms that are crucial for the maintainance of a healthy pond and for the balance of the food chain.

Moreover, it could lead to algal blooms that result in a lower concentration of oxygen available for other organisms.

<em>Over 0.2 per L could be lethal</em> to some fish species that are also important for the health of the alligator pond.

<em>Less than 0.1 </em>indicates a healthy alligator pond.

  • <u>Bacterial coliform test</u>

This test determines the amount of bacteria that comes from waste (animal or human), which could lead to mild to serious bacterial infections and diseases.

If it is a healthy pond, the results should indicate <em>less than 10 fecal coliform bacteria/100 mL.</em>
