In most countries, nitrate levels in drinking-water derived from surface water do not exceed 10 mg/l.
What is a safe level of nitrate in drinking water?
The U.S. Environmental Protection Agency (EPA) standard for nitrate in drinking water is 10 milligrams of nitrate (measured as nitrogen) per liter of drinking water (mg/L). * Drinking water with levels of nitrate at or below 10 mg/L is considered safe for everyone.
What is the maximum permissible limit of nitrate for drinking use?
The Environmental Protection Agency (EPA) has since adopted the 10 mg/L standard as the maximum contaminant level (MCL) for nitrate-nitrogen and 1 mg/L for nitrite-nitrogen for regulated public water systems.
What is the nitrate level in tap water?
The federal standard for nitrate in drinking water is 10 milligrams per liter (10 mg/l) nitrate-N, or 45 mg/l nitrate-NO3. when the oxygen is measured as well as the nitrogen. Unless otherwise specified, nitrate levels usually refer only to the amount of nitrogen present, and the usual standard, therefore, is 10 mg/l.
How do you get nitrate levels down?
Water changes: Performing regular water changes with water that has little or no nitrate will lower the overall nitrate level in the aquarium. If your local tap or well water is high in nitrate, using deionized water (DI) or reverse osmosis water (RO) can help keep nitrate levels low when doing a water change.
Do water filters remove nitrates?
The only way to remove nitrates from drinking water is through a water filtration system. Many water treatment companies promote Reverse Osmosis (RO) systems as an immediate solution to provide nitrate and nitrite reduction.
What is permissible limit?
Permissible exposure limit (PEL) is a regulatory limit on the amount or concentration of a substance in the air. This is usually based on an eight-hour time weighted average (TWA), although some are based on short-term exposure limits (STEL). Workplace environmental exposure limit (WEEL) may be expressed as TWA.
Is there a limit for drinking water?

How do you remove nitrates from tap water?
Nitrates can be removed from water by reverse osmosis, distillation, or through ion exchange resin. Nitrates are difficult contaminants to eliminate from water. Nitrates will not be removed by sediment filters, carbon filters, or by the hollow fiber membrane of an ultrafiltration system.
How high is too high for nitrates?
Although many aquarists run their tanks with extreme nitrate levels, the ideal is a maximum of 5 to 10 ppm. Levels of 20 to 50 ppm are too high.
