4. According to the EPA Lead and Copper Rule (LCR), the action level for Pb in drinking water (the level at which threat to human health requires public notification and action towards mitigation) is 15 ppb. If you were to add enough phosphate to the system saturated with respect to Pb3(PO4)2(s), would the [Pb2+] be below the action limit? Show your work in converting Pb2+ from molarity to ppb. 5. Given what you know now, do you recommend the addition of phosphate to the water supply (why)?
