Hi Everyone! Wondering if anyone can help?
We are looking at new sand media vendors for our BSF and iSSF sand. We found a vendor, and had the sand tested for arsenic, nitrites, nitrates and manganese; however, the sand was found to have high arsenic levels at 18ppb.
Questions
Do you know if the arsenic leaching from the sand media into the water will decrease over time?
Do you know roughly how long it could take, until arsenic levels from 18ppb decrease to 10ppb or lower, after installing the sand media?
