Arsenic in Water Solutions

REMOVING ARSENIC IN WELL WATER

Approximately 20 percent of private wells in Massachusetts produce water that exhibit unhealthy levels of naturally occurring arsenic in water. Well inspection and testing well water is the best way to make sure that your water is clean and safe to drink.

This contaminant may occur naturally and is tasteless, odorless and colorless. Some activities that could also have left residuals include apple orchard spraying, coal ash disposal, and use of some pressure treated wood. Oxford homeowners can be very surprised when they get their laboratory water test results back and see they have arsenic in their water. While there are serious health threats associated with ingestion, there are effective methods for removal. For detail on potential health affects, see the link at: who/mediacentre/facts.

Many removal media have a low capacity for removing AS III from the water, therefore, converting it to AS V for removal is a common approach. Determining the ratio of the two in the water is critical for designing and implementing a water treatment system that will effectively remove it from your drinking water. There are methods to oxidize the AS III and convert it to AS V for ease of removal.

WATER TESTING & ANALYSIS

Having a complete laboratory water test and analysis, including parameters that can negatively impact arsenic removal media, is critical to a well designed, safe water treatment system. pH can significantly affect media performance along with other competing ions such as Iron, Manganese, Hardness, Vanadium, Sulfate, Phosphate, Silica, Total Dissolved Solids, Suspended Solids and Hydrogen Sulfide.

WATER USAGE MONITORING

Determining water usage is also critical to designing an effective arsenic in water removal system that will have the proper capacity. Key information would include well pump size, well pump flow rate, size of the incoming water line, number of residents in the home, the number of bathrooms, space availability for equipment installation, electrical availability and water discharge location or restrictions, among others.

TRACKING WATER USAGE, POST INSTALLATION IS IMPORTANT

A couple of key components for consideration when designing this type of system include:

  1.  Utilizing a meter to track flow rate and total gallons processed is critical to determine the home’s water demand.
  2.  Gallons used readings also assist in uncovering any potential leaks in the home such as running toilets, which will unnecessarily prematurely deplete the arsenic media’s capacity.

LEAD/LAG TANK SET-UP CREATES BACK-UP AND INCREASES SAFETY

Because Arsenic in well water is a tasteless, colorless and odorless contaminant, it is particularly important to have two tanks in series in case the first tank is depleted  prior to scheduled service with your water treatment company. Service should be scheduled at intervals determined by the water use tracking data accumulated. This combined with appropriate water testing intervals are added safeguards to prevent Arsenic from getting into the treated water entering the home.
