Overview of Nitrate Measurements in Ingham County Aquifer

Median and range in local sampling

The U.S. Geological Survey conducted groundwater sampling from 45 wells in the Ingham County aquifer between October 2015 and July 2017. Inorganic nitrogen (nitrate and nitrite) was detected in 6 of 51 results, with a median concentration of 0.335 mg/L and a range from 0.04 to 4.54 mg/L. Most results, 45 out of 51, were below the reporting limit.

Depth of sampled wells

Sampled wells ranged in depth from 7 to 221 feet, covering typical residential well depths in the area, providing a broad overview of nitrate presence in the local aquifer.

Comparison with federal thresholds

No nitrate concentration in the sampling set exceeded federal health-based limits, indicating the regional groundwater nitrate levels are generally within recognized safety margins.

Distinguishing Nitrate from Commonly Confused Water Issues

Nitrate versus iron and manganese issues

Nitrate is an inorganic nitrogen compound that differs significantly from iron or manganese, which primarily cause staining and taste issues but are not nitrogen-based.

Nitrate versus microbial contamination

Nitrate presence is unrelated to microbial pathogens; it does not indicate bacteria or viruses and is measured separately through chemical analysis rather than microbiological tests.

Nitrate compared to aesthetic factors

Nitrate levels affect water quality differently than substances linked to aesthetic secondary standards, such as chloride or total dissolved solids, which influence taste and corrosiveness but are unrelated to nitrate chemistry.

Long-Term Effects If Nitrate Remains Untreated

Potential health concerns

While the area's nitrate levels are below federal limits, individual well owners should be aware that elevated nitrate, if present, can pose health concerns over time, especially for infants and pregnant women.

Water appliance impacts

Unlike minerals causing scaling, nitrate does not typically harm plumbing or appliances but can impact water quality from a health perspective.

Importance of regular testing

Chronic nitrate presence can develop gradually, emphasizing the need for regular water testing to monitor changes and evaluate treatment needs.

The Role of Plumbing Material and Age in Nitrate Issues

No direct impact of plumbing materials

Nitrate originates in groundwater and is not introduced or removed by plumbing materials or pipe age.

Corrosivity and nitrate levels

Corrosivity is influenced by other factors like chloride and pH; nitrate does not contribute to pipe corrosion or leaching in household water systems.

Separating source water quality from plumbing influences

Understanding that nitrate concerns come from source water helps clarify the need to test water before considering plumbing-related causes.

Additional Questions for Commercial or Industrial Water Users Compared to Households

Volume and flow rate demands

Commercial users often require treatment systems that handle higher throughput, making equipment selection more complex than typical household needs.

Regulatory compliance considerations

Businesses may face more stringent monitoring and reporting rules compared to residential users regarding nitrate levels.

Process water quality impact

Industrial processes may be sensitive to even low nitrate concentrations, necessitating specialized treatment beyond residential requirements.

Closing: The Key Test to Clarify Your Home's Nitrate Condition

Ordering a laboratory nitrate test for your well water

The definitive way to know your household nitrate level is to collect a water sample from your own well and have it analyzed by a certified laboratory. This test will confirm whether treatment is needed where you live.

Choosing appropriate treatment equipment

If nitrate is detected at levels that warrant treatment, the Pentair Nitrate & Nitrite (Well) Filter ships ready to configure and is designed specifically for residential applications addressing nitrate and nitrite removal.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2017-07-18. These figures describe groundwater sampled in this area. They are not a test of any individual private well - only a test of that well can establish its own water.
