Cane Bay Plantation
Cane Bay Plantation is the largest master-planned community on the Summerville CPW system, so what is true here is true for thousands of nearly identical homes. Cane Bay Plantation 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
Cane Bay Plantation 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.

UCMR5 testing by Santee Cooper at the Lake Moultrie plant that supplies this system measured PFOS at 7.3 ng/L (range 7.2-7.4) and PFOA at 6.65 ng/L (range 5.9-7.4). The EPA maximum contaminant level for each is 4.0 parts per trillion, so both sit above the federal limit. Utilities on this system have until 2031 to comply, and a $96 million treatment upgrade is underway.

Cane Bay Plantation covers more than 4,500 acres in Berkeley County and is built out in separate villages rather than as one tract. Lennar builds Lindera Preserve, Dan Ryan builds Magnolia, and Del Webb operates a gated 360-acre section for residents aged 55 and over. Each village was delivered in a different year by a different builder, so plumbing layouts vary more across Cane Bay than in a single-builder community.
Lakes of Cane Bay is built around a 300-acre lake used for kayaking and paddleboarding, and the Magnolia village has six ponds. None of that surface water is what comes out of a Cane Bay tap. Household water arrives from Lake Moultrie through the Santee Cooper plant, and the neighbourhood ponds are stormwater and amenity features. A water test measures what is at your kitchen sink, not what is in the lake.

What Cane Bay Plantation is asking
Not by the published number, but often at the tap. The utility reports Cane Bay Plantation 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 Cane Bay Plantation 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.
Cane Bay Plantation is served by Summerville CPW, 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. Cane Bay Plantation 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.
