Nitrogen-fixing bacteria in soil can convert excess nitrogen into which can contaminate groundwater. a/an forms around a well when the water table begins to slope toward the well. the water in an artesian well comes from a/an aquifer. a well not only has to reach the but also has to go deeper. in most aquifers, the materials that make up the aquifer are relatively which means they aren’t chemically reactive aquifers are most prone to pollution. the two primary components of a septic system are a septic tank a/an groundwater that comes to the surface naturally is known as a/an (there are no options. its just putting the word that goes in the sentence)

1. nitrogen fixing bacteria soil converts excess "nitrates"

Explanation:

usually caused by low h2o, water movement and lack of minerals to filter water and kill bacteria..

2 primary components of septic system are tank and a septic pump to regulate waste and store it in a tank underground. when full, a service has to engage in emptying the tank or it will contaminate water supply...

the answer is a) cell division.

hope this !
