I am on a well and both of the wells, as well as all the neighbors wells have ~30ppm nitrates and .25 ammonia in "fresh" water. The pH is also coming in at 6.2. This started this spring and I have to assume it is from the large corn field 150ft from one well and maybe 400ft to another. All last summer and winter the tests were recording 6.8pH and no ammonia or nitrates.

Should I be worried that I have to use this water? I can treat the pH but certainly not the nitrates.

Any ideas would be appreciated

Where do you live? A big change might be something to think about. If you are in Fairfax, Fairfax Water might be able to test your water for contaminants.

Farms should not affect peoples wells, but home owners probably lose to farmers.

Ammonia removers will probably take out the nitrates.

I agree that farms should not, but nitrates in well water can only get there 2 ways one being septic and the other fertilizer. Septic is 150ft to one well, but there is nothing even close to the other. My guess is it has to be the farm, the timing matches.

In any case, is ~30ppm something to be concerned with? Granted its low, but it is also my baseline. pH can be corrected but I have yet see plans out there to remove nitrates on a large scale.

Growing plants and it would be fine. I think if are raising fry and it would not. There are a lot of products that reduce or neutralize nitrate. Check them out.

I agree with Rick. Even 10ppm of Nitrates would be harmful to fry. Large scale treatment is possible but depends on the Budget.

What then would the solutions be for say 2000 gallons on central system? I am planning on using a Walmart MARS system I have for the adults, it is 3 racks of 3 shelves consisting of a 40gallon tank divided 3 ways. Also I have 3 100g acrylics that can be divided 4 or 8 ways, really nice tank but a shame I can't find more. The fry/sub adults will start off in 2qt containers and move into 2.5 to 4g as they grow.

As long as you had a holding tank or changed water slowly enough that the biofilter broke down the nitrates.

Large sump with biofilter and nitrate removers could handle it.
