Which of the following is caused by pollutants from farm runoff, feedlots, or septic tanks? . increased fecal coliform . low dissolved oxygen . temperatures greater than 45°c . ph below 6.5 .

 Increased fecal coliform

Explanation:

The fecal coliform is a strain of bacteria which can be found in colonies in the digestive tract of humans and animals. It comes out along with the fecal discharge from the body.

If the solid and liquid matter from any of these discharges enters into a fresh water body will likely to cause pollution because of the presence of fecal colliform. It results in appearance of foul smell in water and likely to deteriorate the quality.
