Natural levels of nitrate in Minnesota groundwater are usually quite low (less than 1 milligram per liter [mg/L] of nitrate-nitrogen). However, where sources of nitrate such as fertilizers, animal wastes, or human sewage are concentrated near the ground surface, nitrate may seep down and contaminate the groundwater. Elevated nitrate levels in groundwater are often caused by run-off from barnyards or feedlots, excessive use of fertilizers, or septic systems.
Wells most vulnerable to nitrate contamination include shallow wells, dug wells with casing which is not watertight, and wells with damaged, leaking casing or fittings.
Nitrate contamination of a well is often regarded as a first sign of deteriorating groundwater quality.
Settlements because it all depended on the people who affected them with the religious activities
Yes, because each of the four nucleotide bases present in DNA have a corresponding base: adenine bases always pair with thymine bases, and cytosine bases always pair with guanine bases. For example, if one strand of a DNA molecule was CTAGGT, the sequence of the second strand would be, from left to right, GATCCA.
