Highland Park’s water is already membrane-filtered, carbon-filtered and partially softened at the municipal plant. Residential treatment is refinement beyond that strong baseline—not a claim that the utility failed.

Local Insight: Highland Park is supplied by the Dallas County Park Cities MUD, which utilizes advanced membrane filtration and lime softening (resulting in a low average of 1.6-5.4 GPG hardness).
Hardness Level
Impact: Reduces appliance life, etches glass, and leaves soap scum on skin.
Recommended Fix: Water Softener →Disinfectant
Impact: Can cause chemical taste/odor and dry out hair & skin.
Recommended Fix: Carbon Filter →We maintain active residential routes throughout Highland Park and surrounding neighborhoods, directly addressing the impact of local water infrastructure. Because municipal water here often contains slightly hard to moderately hard levels of dissolved minerals combined with chloramines treatments, standard pitcher filters and uncalibrated softeners typically degrade quickly.
To ensure lasting results for our Highland Park, TX clients, we install commercial-grade high-capacity ion exchange softeners paired with dedicated Water Fixers Carbonyx Elite™. This specific combination guarantees zero-scale buildup on fixtures and completely removes chemical odors right at the main water line before it enters your home. All installations are performed directly by a licensed Texas water treatment specialist.
Generating Water Report...
Regulatory Standard: Municipal water in Highland Park and surrounding municipal systems fully complies with the U.S. Environmental Protection Agency (EPA) Safe Drinking Water Act (SDWA) and local state regulations, making it legally safe and approved for consumption.
EWG Thresholds: The Environmental Working Group (EWG) is an independent non-profit research and advocacy organization. EWG "Health Guidelines" are not legally mandated federal standards. While federal standards (MCLs Set by the EPA) must balance economic feasibility, treatment costs, and technological limits faced by municipalities, EWG guidelines are based on pure academic health guidelines and research, independent of municipal feasibility or infrastructure costs.
Safe vs. Ideal: While municipal water passes all legal safety standards, "safe" is not the same as "ideal." Aesthetic contaminants, mineral hardness (hard water), residual chlorine, and chloramines can negatively impact skin, hair, high-end appliances, and drinking water taste. Our systems act as personal aesthetic and purification barriers to bridge the gap between regulatory guidelines and the highest standard of clean, pure water for your home.
Highland Park purchases its regular supply from the Dallas County Park Cities Municipal Utility District.
The Park Cities MUD draws surface water associated with Grapevine Reservoir and the Elm Fork of the Trinity River. Its treatment plant serves both Highland Park and University Park.
Highland Park also maintains two Dallas Water Utilities interconnections for emergency and maintenance use, but Dallas is not the town’s normal primary supplier.
That distinction gives Highland Park a genuinely separate water story from the surrounding City of Dallas.
The shared Park Cities treatment process is more advanced than the generic phrase “city water” suggests.
Official Park Cities materials describe:
The lime stage reduces hardness before the water reaches Highland Park, and the GAC plus membrane process provides a sophisticated municipal barrier.
The current Highland Park report confirms the effect: average tap-water hardness was approximately 42 mg/L as calcium carbonate, with a range of 28–93 mg/L—about 1.6–5.4 grains per gallon.
That is distinctly softer than many other DFW municipal supplies.
A generic city page claiming Highland Park receives 7–11 grains per gallon would be wrong according to the current report.
Highland Park’s 2025 report states that the town met or exceeded applicable state and federal water-quality requirements and retains TCEQ’s Superior Public Water System designation.
This is not a page about rescuing dangerously untreated water. It is about defining the difference between excellent public treatment and one household’s preferred final water.
The finished water still carries a chloramine residual. Highland Park reported a 2025 average of approximately 2.99 mg/L, with results from 1.20–3.60 mg/L.
The report also listed:
Municipal treatment has reduced many constituents substantially. It has not made the water chemically blank.
EWG’s Highland Park profile reports:
Highland Park’s current municipal report separately lists PFHxS at an average of 0.0033 micrograms per liter in its 2023 UCMR5 data, equivalent to 3.3 ppt. It also reports PFBA, PFBS, PFHxA and PFPeA detections under the federal unregulated monitoring program.
The EWG profile and the current CCR use different averaging windows, so their PFHxS values should not be presented as though one is a correction of the other.
The proper conclusion is narrower and stronger: even a highly treated municipal supply can contain detectable chloramine, treatment byproducts and PFAS compounds that a homeowner may prefer to reduce further at home.
Water Fixers DFW has completed residential water-treatment work in Highland Park.
The town’s lower hardness changes the softener conversation. It does not eliminate it.
A home testing near the low end of the reported range may require relatively modest softening capacity. A property receiving water near the higher end, or one whose owner strongly dislikes any spotting or hardness feel, may still gain clear value from ion exchange.
The mistake would be installing and programming Highland Park equipment as though the water were identical to a 10- or 14-grain North Texas supply.
Private plumbing, water heaters, recirculation, existing treatment and household flow still shape the final design. Those considerations are legitimate without resorting to assumptions about home value, fixture materials or lifestyle.
Clarion Elite addresses the remaining calcium and magnesium hardness.
Because the municipal plant already performs lime softening and current hardness is relatively low, Clarion Elite should be sized and programmed with precision. The goal is polished soft-water performance without unnecessary resin volume or excessive regeneration.
Carbonyx Elite provides the whole-home catalytic carbon stage for the residual chloramine and for appropriate taste, odor, organic-compound or disinfection-byproduct goals.
The fact that the Park Cities plant already uses granular activated carbon does not make residential carbon redundant. Municipal carbon is one stage within the treatment plant. Highland Park then intentionally maintains chloramine for distribution after treatment.
Carbonyx Elite is the final household barrier that treats the residual entering the property, provided its media volume and contact time match the home’s flow.
ClaRO provides point-of-use reverse osmosis for drinking and cooking water.
This is the more relevant stage for homeowners seeking a more selective barrier for nitrate, PFAS and other dissolved constituents reported through the CCR or EWG profile, subject to membrane certification and operating conditions.
Official Water Quality & Licensing Disclaimer:
Water quality metrics and municipal report data listed on this page are gathered in good faith from public records, including the Highland Park, TX Annual Water Quality Consumer Confidence Reports, water-provider maps, and third-party databases such as the Environmental Working Group (EWG) Tap Water Database. While we make every effort to verify information regularly, public water conditions, source water reservoir blends, and municipal disinfection practices fluctuate over time.
Any specific on-site measurements, system recommendations, or custom hydraulic configurations represent professional field diagnostics performed by our licensed specialists. This site-specific data should not be used as a substitute for an active physical site water analysis. All professional treatment proposals, including system sizing and chemical reduction metrics, are customized according to physical conditions at the property.

Not during normal operation. The town purchases from the Dallas County Park Cities MUD and keeps Dallas interconnections for emergency or maintenance use.
It is substantially softer than many DFW supplies. The 2025 report lists an average of about 42 mg/L, or roughly 2.5 grains per gallon, with a range of about 1.6–5.4 grains.
The plant’s GAC is part of municipal treatment. Chloramine is added for distribution afterward. Carbonyx Elite addresses the residual and additional household treatment goals at the property.
No. The CCR identifies the values as UCMR5 occurrence data. EWG provides a separate independent benchmark. The data can support a homeowner’s decision to add ClaRO without being misrepresented as a municipal violation.
No. The reported hardness is relatively low and variable. Clarion Elite is most compelling for homeowners who want near-zero hardness performance or whose property tests toward the upper end of the range.
Hard water and city chloramines quietly destroy appliances, ruin plumbing seals, and force you to buy twice as much soap. Here is the realistic math on what untreated water is costing you.
Soaps & Chemicals ($432/yr): With 3 people, you use ~50% more soap just to lather ($8/mo per person waste). Plus ~$12/mo on heavy-duty shower cleaners like CLR to scrub off scale.
Gas/Electric Energy ($75/yr): Scale insulates water heater elements. For a household of 3, this drops heating efficiency significantly, costing ~$25/yr per person in wasted gas or electricity.
Appliance Lifespan ($88/yr): Hard water scale cuts the 12-year lifespan of standard water heaters, washers, and dishwashers by nearly 30%.
Plumbing Leaks ($96/yr): Municipal chloramines dissolve rubber toilet flappers and plumbing seals, averaging nearly $100/yr in phantom water leaks and frequent plumber visits.
