How do you test for radon in water?

Testing Radon in Water The concentration of radon in water can be determined using one of three analysis methods: liquid scintillation, gas extraction, or direct gamma counting. Of these, liquid scintillation is considered to be the most accurate method, with detection limits close to 1 Bq/L for a sample size of 40 mL.

Can radon come from well water?

Radon can build up in water from underground sources (groundwater). Radon is not a concern in water from lakes, rivers, and reservoirs (called surface water). Groundwater is the source used in private wells and in some public water supplies.

How do you filter radon out of well water?

Aeration – Because radon is a gas, it is possible to remove it from the water by simply blowing air through the water and pushing the resulting vapor out away from the home – typically through a pipe on the roof. Usually, these aeration systems work by having an air source at the bottom of a water storage tank.

Where is the best place to put a radon test?

Place a radon detector in the breathing zone, 2-6 feet above the floor, and away from drafts, exterior walls, sumps, drains, windows or doors. Radon may enter a building through cracks in the foundation or through sumps or drains and will usually be higher near these entry points.

How common is radon in water?

The average concentration of radon in public water supplies derived from ground water sources is about 20 becquerel per liter (540 pCi). Some wells have been identified with high concentrations, up to 400 times the average.

What is a high radon level in water?

EPA and various states have recommended drinking water standards for radon in water ranging from 300 to 10,000 pCi/L but no standard currently exists. One study of radon in over 900 Pennsylvania water wells found that 78% exceeded 300 pCi/L, 52% exceeded 1,000 pCi/L and 10% exceeded 5,000 pCi/L.

Does a water softener remove radon?

The diffused bubble aerator with water softener provided the most successful mitigation with 99.9% radon removal efficiency, while the spray and diffused aerator tank with charcoal filter tank produced the least successful radon removal efficiency at 77.7%.
