Arsenic and Old Media…
In the last water Blog we discussed Arsenic Adsorption systems using a Lead/Lag design. Currently the NHDES is not controlling the disposal of Arsenic saturated media for Residential applications. You can take the used media to the town land fill and dispose of it there, unless your town has rules about the disposal of special waste.
For Public Water Systems (PWS) the NHDES is taking a more active role in enforcing the rules for the disposal of special waste. Currently when a PWS hires us to rebed their Arsenic Media we will sample the media and have a T-CLP test performed before having it incinerated. The T-CLP test proves that the Arsenic will not leach back off of the media during transportation or if it is buried in a land fill. Our preference is incineration because it is a final solution that will not come back to haunt anyone later if the rules change. The end customer is supplied with copies of the bill of lading, invoice for incineration and the T-CLP test for their records. It’s really a lot simpler than it sounds. In time this type of service may become necessary residentially, but not anytime soon.
So far we have discussed the removal of Arsenic from water using a Whole House approach through Adsorption. Next time I will cover the different types of point of use Drinking Water Systems for the removal of Arsenic from water.
