There are currently five old coal ash ponds at Dominion Resources Possum Point Power Station near Quantico, Virginia which is in the 36th District. Coal ash or fly ash is the end product of burning coal to create electricity. Decades ago, it was common practice to mix it with water and store it in ponds into a “slurry.”
If ponds are not properly lined with impermeable barriers, then they can leach toxic metals into ground water and surface water. According to some sources, depending on the coal used, they can leach toxic elements such as arsenic, beryllium, boron, cadmium, chromium, hexavalent chromium, cobalt, lead, manganese, mercury, molybdenum, selenium, strontium, thallium, and vanadium, along with dioxins and PAH compounds. Metals like this store in the fatty tissues of fish and can aggregate in fish consumers such as birds or humans. Modern practice is to store ash in dry landfills.
