Goose Creek
Goose Creek runs its own distribution system but buys the same Santee Cooper water as Summerville CPW and BCWS. Goose Creek water has a published hardness of about 1.4 grains per gallon (23 to 25 ppm total hardness), but our in-home field tests regularly read 3 to 6 grains per gallon at the tap.
Your utility
Goose Creek water has a published hardness of about 1.4 grains per gallon (23 to 25 ppm total hardness), though our in-home field tests regularly read 3 to 6 grains per gallon at the tap. It is disinfected with chloramine at about 3.27 ppm. UCMR5 testing by Santee Cooper at the Lake Moultrie plant measured PFOS at 7.3 ng/L and PFOA at 6.65 ng/L. The EPA limit for each is 4.0 parts per trillion, so both are above the federal limit. Utilities on this plant have until 2031 to comply and a $96 million upgrade is underway.

Municipality
Goose Creek (Berkeley County)
Goose Creek runs the City of Goose Creek water system, serving roughly 38,000 residents through its own distribution network. The treated water itself is bought from the Santee Cooper Regional Water System and drawn from Lake Moultrie, the same plant that supplies Summerville CPW and Berkeley County Water and Sanitation. Separate pipes, one source, which is why the published hardness and PFAS figures match across all three.
Goose Creek water is published at about 1.4 grains per gallon, but our in-home tests here regularly read 3 to 6 at the tap, so we set up any system from your own reading. The chloramine residual runs near 3.27 ppm and does not dissipate from a pitcher left on the counter. PFOS and PFOA both test above the EPA limit of 4.0 parts per trillion. Those are filtration questions. Hardness is a question for your own tap.

What Goose Creek is asking
Not by the published number, but often at the tap. The utility reports Goose Creek water at about 1.4 grains per gallon (23 to 25 ppm total hardness), which is soft by the USGS scale. That is a system average, though. Our in-home field tests regularly read 3 to 6 grains per gallon at the tap, slightly hard to moderately hard, which is enough to show up as spotting and scale. That is why we test your own tap before recommending anything.
Yes. UCMR5 testing by Santee Cooper at the Lake Moultrie plant measured PFOS at 7.3 ng/L and PFOA at 6.65 ng/L. The EPA limit for each is 4.0 parts per trillion, so both are above the federal limit. Utilities on this plant have until 2031 to comply and a $96 million upgrade is underway. Along with the hardness we measure at the tap, it is a main reason to consider treatment here.
It depends on your tap. The published figure for Goose Creek water is about 1.4 grains per gallon, but our in-home tests here regularly read 3 to 6 grains per gallon, enough to leave spotting and scale over time. The water also carries PFOS and PFOA above the EPA limit, plus chloramine at about 3.27 ppm. Those call for filtration. We test at your tap first and set up any system from that live reading, not the utility average.
Goose Creek is served by the City of Goose Creek water system, which buys treated surface water from the Santee Cooper Regional Water System. The source is Lake Moultrie. Santee Cooper adds chloramine as the secondary disinfectant to limit the formation of TTHMs and HAA5s.
Chloramine. Goose Creek water is disinfected with chloramine rather than free chlorine, averaging about 3.27 ppm. Chloramine holds its residual all the way to the tap instead of off-gassing, which is good for microbial safety and is also why the taste does not disappear if you leave a pitcher on the counter. Removing it takes catalytic carbon.
