Carnes Crossroads was built on a specific idea: sustainable agriculture, local food, intentional green space, and a community that cares about what goes into their bodies.
If you chose Carnes Crossroads because you value transparency about food, this report applies the same transparency to your water. Every number is cited. Nothing is invented.
Your Water Source
Carnes Crossroads is in Berkeley County, within Goose Creek city limits, and is served by Summerville Commissioners of Public Works (CPW). CPW sources surface water from Lake Moultrie via the Santee Cooper Regional Water System.
You share the same utility as Nexton, Cane Bay Plantation, Foxbank, and Summerville proper. The water entering your Lennar or Eastwood Homes build is the same water entering a Nexton home.
Hardness: 7.2 Grains Per Gallon
CPW water measures about 7.2 grains per gallon (gpg), moderately hard per the USGS hardness scale. For comparison, Charleston Water System (serving peninsular Charleston, James Island, and West Ashley) runs about 3.4 gpg.
If you moved from the Northeast, California, or coastal Florida, you were likely on softer water. That's why your showerhead is scaling, your dishes are spotting, and your soap isn't lathering the way it used to.
What 7.2 gpg Looks Like
- White scale buildup on showerheads and faucets within 30-60 days
- Film on glassware from the dishwasher
- Soap and shampoo residue on skin and hair
- Stiffer laundry and faster towel degradation
- Gradual water heater element scaling
None of this is a health issue. Calcium and magnesium are safe to consume. This is an aesthetic and maintenance concern.
Chlorine Disinfection
CPW uses chlorine (not chloramine) as its primary disinfectant. The pool smell some residents notice in the morning or from hot water taps is normal at regulated levels.
Why does this matter? Chlorine and chloramine are different chemicals with different filter requirements. Most countertop or fridge filters are designed for free chlorine. They work fine on CPW water. But if your friend in Mount Pleasant or West Ashley is on Charleston Water System (which uses chloramine), their Brita isn't doing the same thing yours is. Chloramine needs catalytic carbon or a blended media with longer contact time.
In Carnes Crossroads, you're on chlorine. A standard carbon filter handles the taste at the kitchen tap.
EWG Flags: 11 Contaminants Above Health Guidelines
The EWG Tap Water Database tested Summerville CPW water from 2014 to 2023 and flagged 11 contaminants above EWG's own health guidelines. The headline numbers:
| Contaminant | EWG Multiple | Measured Level |
|---|---|---|
| PFUnA (PFAS compound) | 1,183x guideline | 7.1 ppt |
| HAA9 (disinfection byproduct) | 368x guideline | 22.1 ppb |
| TTHMs | 168x guideline | 25.2 ppb |
| Bromodichloromethane | 137x guideline | 8.25 ppb |
| HAA5 | 113x guideline | 11.3 ppb |
| PFDoA (PFAS compound) | 75x guideline | 4.50 ppt |
All readings are within EPA legal limits. EWG uses stricter benchmarks based on their assessment of newer health research. The data is public and verifiable at the link above.
Important context: "above EWG guideline" does not mean "illegal." Every reading is below the EPA Maximum Contaminant Level. EWG's guidelines represent a different risk threshold. Both positions are published.
Zero Lead Service Lines
CPW's completed inventory found zero lead pipes in the system. Your service line from the street to your Carnes Crossroads home is not lead per the published data. This stands in contrast to Charleston Water System, which identified about 6,000 lead service lines in older neighborhoods.
The March 2026 Advisory
On March 17-18, 2026, about 70,000 CPW customers were placed under a boil-water advisory after a contractor punctured the Santee Cooper main line. Carnes Crossroads was in the affected zone. The advisory was lifted 24 hours after repair.
The Growth Context
Carnes Crossroads sits within a Berkeley County growth cluster that has added roughly 27,000 residents since 2015. The community is still building out toward a projected additional 7,000 residents. A Roper St. Francis 66-acre healthcare facility is planned for the commercial frontage.
New homes, new pipes, same utility. Your plumbing is new. Your water is the same 7.2 gpg CPW has always delivered.
The Carnes Crossroads Community Ethos
Carnes Crossroads was developed by Daniel Island Company on 2,300 acres with a community ethos built around sustainable agriculture, local food, and intentional green space. The community has two pools, playgrounds, tennis and pickleball courts, and hundreds of acres of parks. A 66-acre Roper St. Francis healthcare facility is planned for the commercial frontage.
The community attracts residents who do their homework. Families who read ingredient labels, who buy local at the farmer's market, who care about what enters their household.
Water is part of that equation. It touches your food, your skin, your dishes, your laundry. If you care enough to buy organic produce and plant-based soap, the water those products interact with deserves the same scrutiny.
FAQ: Carnes Crossroads Water
Is Carnes Crossroads water the same as Nexton?
Yes. Both communities are served by Summerville CPW. Same source, same hardness, same disinfection method, same EWG profile.
Does Carnes Crossroads have lead pipes?
No. CPW's completed inventory found zero lead service lines. Your Carnes Crossroads home connects to the street through non-lead piping per the published data.
Why does my showerhead have white crust?
That's calcium and magnesium scale from 7.2 gpg hard water. It starts building within 30-60 days of install and accelerates over time. It's not harmful, but it clogs nozzle holes and reduces flow.
The Transparency You're Used To
You chose a community that labels its food sourcing. This report labels your water sourcing. Every number above has a citation. If you want to go deeper than the CCR, the EWG profile for Summerville CPW is public, and Summerville CPW publishes their own annual report.
If you want to see what your specific tap is putting out, beyond the utility-level averages, a free in-home water test is the most direct path. I'll bring the kit, test your tap, and walk through the numbers on your counter. No obligation.
If your water's fine, I'll say so.
