Nitrates can enter a freshwater source through runoff from agricultural fields where fertilizers are used, as well as from leaking septic tanks, livestock waste, or wastewater treatment plants. Once in the water, nitrates can lead to eutrophication, which can harm aquatic life and degrade water quality.
Chlorine substances can enter a freshwater source through the discharge of treated wastewater from industrial facilities or wastewater treatment plants. Runoff from agricultural fields where chlorine-containing fertilizers or pesticides have been used can also introduce chlorine into freshwater sources. Improper disposal of cleaning products or chlorine bleach near rivers or streams is another potential source of contamination.
Nitrates can enter urine through dietary ingestion of nitrates from foods such as leafy green vegetables, root vegetables, and processed meats. The body metabolizes dietary nitrates into nitrites, which are then excreted in the urine.
Acid can enter a freshwater source through sources such as acid rain, runoff from mining or industrial activities, and discharge from wastewater treatment plants or other facilities that release acidic substances into water bodies. These inputs can lower the pH of the water, making it more acidic and potentially harmful to aquatic life.
Nitrates are compounds often found in fertilizers and can also be naturally occurring in soil and groundwater. Excessive levels of nitrates in drinking water can be harmful to human health, particularly to infants and pregnant women.
Nitrates are a major part offertilizers, so when we use fertilizers they get in the soil and from there to the underground water supply.The reason they usually get past the purification at the water plant is that nitrates are very soluble in water and very hard to separate

Nitrates enter the cell through the process of active transport. Nitrates are essential for development of leaves of a plant and are absorbed through root hair cells.

The main source of freshwater is from the clouds... And the refrigerator
The most abundant source would be in glacial form as frozen water, although the most abundant and accessible source is groundwater.
If the questions is what is the waste product of freshwater fish, then that would be ammonia. Freshwater fish product ammonia which is excreted through their gills and into their water, to keep this poisen to a minimum you need to a filter which has bacterial build up in the media which lives on ammonia and converts it into nitrite, then another group of bacteria absorb nitrite and product nitrates. Nitrates are much less dangerous to fish and some of them are used up by plants so planted tanks are much healthier for fish nitrates however do need to be kept low and weekly water changes should do that effectively.
PH,ammonia,DH,nitrites and nitrates. look for "tetra easy strips" is pet stores
