Moultrie Water Hardness & Quality Report (2026)

Moultrie, Georgia, in Colquitt County — the Colquitt County seat adjacent to Thomasville and Valdosta in southwest Georgia — receives its water from the Moultrie Water Division, drawing from the Floridan Aquifer (Colquitt County) through the southwest Georgia water treatment system.

The hard 160 mg/L hardness and TDS of 429.5 mg/L reflect the southwest Georgia Floridan Aquifer's hard calcareous character — harder than the northwest Florida Escambia Floridan communities (Warrington: 128 mg/L) due to the deep southwest Georgia Floridan Aquifer's more concentrated calcareous limestone dissolution at the interior Colquitt County position. The Floridan Aquifer at Colquitt County is developed in Eocene Avon Park Formation (calcareous — primary hardness contributor), Oligocene Suwannee Limestone (calcareous — secondary contributor), and Eocene Ocala Limestone (calcareous). The deep southwest Georgia Floridan Aquifer calcareous dissolution produces the hard supply.

At 160 mg/L, Moultrie's water is hard — scale builds steadily in kettles and appliances, dishwashers benefit from rinse aid, and water heaters should be descaled annually. Monthly descaling is recommended. The PFAS level of 9.4 ppt warrants a certified reverse osmosis drinking water filter — Moody Air Force Base (Lowndes County — AFFF) and the southwest Georgia military corridor contribute to Moultrie's elevated readings.
