Well testing and clean water

Why Should I Test my Well Water?

The EPA recommends well testing for bacteria and nitrates, as well as total dissolved solids and pH levels. High levels of bacteria and/or nitrates in your water can lead to health issues. While the total dissolved solids and pH levels do not put your health at risk, they can affect the overall function of the well and connected water filtration systems. Testing regularly is not only an insurance for your personal health; it can save you money over time with a system that runs smoothly.

How Often do I Need to Test my Well Water?

The EPA recommends annual testing of well water. If you notice changes in odor, taste or other qualities, then conduct a well water test as soon as possible.

How Much Does a Water Test Cost?

The cost of a test varies by location and the type of test needed. Contact Hague Quality Water of Maryland for advice on the recommended test(s) for your area. Once you determine your well testing needs, our certified water testing professionals can provide a more accurate cost.

What Should I Test For?

Well water testing services may include testing for the following contaminants – Bacteria, Total Coliform, E.coli, pH, Turbidity, Iron, Lead, Nitrate, Radium, Arsenic, Cadmium and salt-water intrusion. The type of test may vary within a small radius. A water treatment specialist can advise you on the test(s) needed for your area.

Do I Need to Become an Expert on Water Contaminants?

Well water testing may sound overwhelming. You do not need to be an expert when it comes to well maintenance and water testing. Leave it to the experts. Select a water test provider certified to work in your state. Many times, the installer of your filtration system maintains partnerships with testing labs and assists with annual tests.

If you REALLY want to learn a little more, here is a breakdown of the most common contaminants:

Coliform bacteria

A type of bacteria found in feces. By themselves, they are not always harmful but they are associated with other disease-causing bacteria. In some cases, more specific tests for fecal contamination, such as E.coli, may be used.


Nitrogen-oxygen compounds commonly found in fertilizers. When ingested or absorbed into the bloodstream, they can interfere with the blood’s ability to carry oxygen, especially in children. Common sources of nitrate to well water are fertilizers, septic systems, animal manure, and leaking sewer lines. Nitrate also occurs naturally from the breakdown of nitrogen compounds in soil and rocks.

Naturally occurring contaminants

Your state may recommend or require testing for certain contaminants specific to your locality. Arsenic and radium are two examples of water-quality concerns in certain areas.

Is There a Testing Requirement for Buying/Selling a Home?


The housing industry and banking community require water testing as part of a real estate transaction. Water testing is required for buying/selling and refinancing. The type of home loan typically dictates the required water test(s).

Conventional Loan – Bacteria and a Chemical Analysis*
VA Loan – Lead, Bacteria and a Chemical Analysis*
FHA Loan – Lead, Bacteria and a Chemical Analysis*

*A Chemical Analysis provides information on pH, clarity, turbidity, iron, nitrate, nitrite, and sand.

Who Should Test my Well?

Home test kits are available and provide specific instructions for water sampling and testing. It is important to handle samples carefully to achieve the best results.

Your results will indicate areas above and/or below the national standards for water outlined by the EPA. The EPA maintains a resource for the national health standards. This list provides specific information about drinking water contaminants. A water treatment expert will be able to explain your results with you and help you determine your next step.

While home test kits may provide an indication of contaminants, we recommend follow up with a professional water test provider. A state certified testing provider will give you the most accurate results. To comply with real estate transaction requirements, use a state certified testing provider, like Hague Quality Water of Maryland.
