Community context
Why Ladera Ranch families are asking questions right now
Recent reports of rare pediatric cancers and community questions about potential environmental exposures have increased the demand for transparency and careful investigation. No public-health investigation has established that Ladera Ranch drinking water caused these illnesses. ADG Water Solutions does not make that claim.
Reported Cases
Families have reported six Ewing sarcoma diagnoses, prompting calls for an expedited review.
Officials have stated that the cause of the reported cancers is not known.

Environmental Questions
Residents have raised questions regarding potential environmental exposures, including landscape-product use.
LARMAC implemented a temporary 60-day pause on certain routine landscape products while reviewing its program. This pause does not establish that the products caused the illnesses, and it does not establish that drinking water was contaminated.

What you can control
You cannot control a regional investigation. You can control the water inside your home.
Four steps, in order. Each one is a decision you own.
- 01
Understand
Review what the current utility report says about the water delivered to your neighborhood, and what it does not address.
- 02
Test
Use a basic in-home screening for characteristics it can measure, and accredited laboratory testing for anything it cannot.
- 03
Treat
Select equipment certified for the specific objective you identified — not equipment chosen before the question was asked.
- 04
Maintain
Keep documented replacement intervals so the system continues performing the way it was specified.
Local water facts
What the current Santa Margarita Water District report actually says
Figures below come from the 2026 Water Quality Report (covering 2025 testing). They describe the water delivered to the district's service area, not the plumbing inside any individual home.
Standards
Met or surpassed
SMWD reports that water delivered during 2025 met or surpassed applicable federal and state requirements.
Meeting applicable standards is a regulatory finding about the delivered supply. It is not a statement about any individual home's plumbing, fixtures or preferences.

Water Source
Imported surface water
Ladera Ranch primarily receives imported, treated surface water.
Source water influences mineral content, taste and the disinfection approach used in the distribution system.
Source: Santa Margarita Water District · View source (opens in a new tab)
Hardness
≈ 15 gpg average
Approximately 15 grains per gallon average, with a reported range of approximately 12.3 to 17.5 grains per gallon.
Hard water can contribute to scale, spotting and reduced efficiency of water-using equipment.

Total Dissolved Solids
≈ 614 ppm average
Approximately 614 ppm average, with a reported range of approximately 510 to 680 ppm.
TDS is a broad measure of dissolved material and is not, by itself, a health-risk determination.

Disinfection
Chloramines
Chloramines are used to help control microorganisms in the distribution system.
Treatment selection for taste, odor or chloramine reduction must match a product's verified performance claims.

Two different jobs
Municipal treatment and home treatment are not competing claims
One protects an entire distribution system. The other addresses what happens at your fixtures, on your glassware and in your appliances.
Public water treatment addresses
- Regulatory compliance
- Disinfection
- Distribution-system safety
- Source-water treatment
- Community-wide reliability
Home treatment may address
- Taste and odor preferences
- Chlorine or chloramine reduction when certified
- Hardness and scale
- Drinking-water treatment at a specific faucet
- Specific tested contaminants within a system's certified claims
- Plumbing and appliance protection
- Household convenience
Start where you are
What made you look into your water?
Select anything that applies. We will show what it usually indicates and the responsible next step — not a product.
Nothing selected yet. Choosing a concern does not commit you to anything.
Selecting a concern does not mean a particular system is required. It identifies the next responsible step.
Honest limits
What an in-home screening can measure — and what it cannot
An in-home screening is not a certified laboratory analysis.
In-home screening can review
- Hardness
- Total dissolved solids or conductivity
- pH
- Chlorine or chloramine indicators where appropriate
- Visible scale and fixture conditions
- Current treatment equipment
- Household water objectives
Requires an accredited laboratory
- PFAS
- Specific pesticides or herbicides
- Volatile organic compounds
- Metals
- Microbiological concerns
- Other specifically identified substances
Treatment options
Five categories, each with a defined job
Equipment is matched to an identified objective. Every category below includes what it does not do.
Whole-Home Carbon Filtration
Treats water as it enters the home, most often selected for aesthetic objectives such as taste and odor.
Treatment objectives
- Taste and odor improvement
- Chlorine reduction
- Chloramine reduction only when supported by the exact product's certification and capacity
- Reduction of specifically listed compounds
- Maintenance
- Media replacement or scheduled media service
- Best suited to
- Homes seeking whole-house aesthetic improvement in taste, odor and chlorine character.
What it does not do: Not every carbon system reduces PFAS. Any PFAS statement must match the specific model's certified reduction claim.
Water Softening
A cation-exchange system that addresses hardness minerals, the primary driver of scale and spotting in South Orange County.
Treatment objectives
- Hardness reduction
- Scale control
- Reduced mineral spotting
- Protection of water-using appliances
- Improved soap and detergent performance
- Maintenance
- Salt monitoring, periodic inspection and resin review
- Best suited to
- Homes with visible scale, spotting or appliance and fixture wear from hard water.
What it does not do: A softener addresses hardness. It is not a substitute for filtration intended to address taste, odor or specific contaminants.
Reverse Osmosis
A point-of-use system that treats water at a specific fixture for drinking and cooking.
Treatment objectives
- Drinking and cooking water
- Reduction of dissolved substances within verified claims
- PFAS reduction only with a product carrying the applicable certification and performance claim
- Maintenance
- Prefilter, postfilter and membrane replacement on schedule
- Best suited to
- Households focused on drinking and cooking water quality or reducing bottled-water use.
What it does not do: PFAS or other health-effect claims apply only to the specific certified model and only within its stated capacity.
Combination System
A coordinated design pairing whole-home treatment with dedicated drinking-water treatment.
Treatment objectives
- Whole-home filtration
- Hardness treatment
- Dedicated drinking-water treatment
- Coordinated maintenance
- Maintenance
- Coordinated schedule across each component
- Best suited to
- Homes addressing hardness, aesthetic objectives and drinking water in a single plan.
What it does not do: A combination design is only appropriate when each objective is identified. Component claims remain product specific.
Specialized Treatment
Equipment selected for a specific condition that has been identified through appropriate testing.
Treatment objectives
- Sediment
- Iron
- Manganese
- Nitrate
- Specific VOCs
- Specific PFAS
- Specific pesticides or herbicides
- Other identified substances
- Maintenance
- Determined by the technology and the measured condition
- Best suited to
- Homes with a documented test result for a specific substance or condition.
What it does not do: Treatment is selected only after the concern and treatment objective are identified.
Side by side
Comparing what each category can be responsible for
“Depends on product” is a real answer. It means the claim must be verified on the specific certified model.
| Question | Whole-home carbon | Softener | Reverse osmosis | Combination | Specialized |
|---|---|---|---|---|---|
| Treats all water entering home | Yes | Yes | No | Yes | Depends on product |
| Treats drinking water at one fixture | No | No | Yes | Yes | Depends on product |
| Addresses hardness | No | Yes | Depends on product | Yes | Depends on product |
| Addresses taste and odor | Yes | No | Yes | Yes | Depends on product |
| May address PFAS when specifically certified | Depends on product | No | Depends on product | Depends on product | Depends on product |
| Requires drain connection | Depends on product | Yes | Yes | Yes | Depends on product |
| Requires salt | No | Yes | No | Depends on product | Depends on product |
Certification literacy
A standard number is not a performance claim
Knowing how to read a certification is the difference between buying equipment and buying an outcome.
NSF/ANSI 42
Generally addresses aesthetic effects such as chlorine, taste and odor.
NSF/ANSI 44
Applies to residential cation-exchange water softeners.
NSF/ANSI 53
Addresses specified contaminants with health effects.
NSF/ANSI 58
Applies to reverse-osmosis systems.
The ADG process

Where we work
South Orange County communities we serve
Every neighborhood has its own plumbing reality. These notes reflect what we actually encounter.
Ladera Ranch
Master-planned neighborhoods on Santa Margarita Water District service, where imported treated surface water arrives hard enough to leave visible spotting on glass and shower enclosures. Homes here often pair a hardness strategy with a dedicated drinking-water fixture.
Rancho Mission Viejo
Newer construction with modern manifold plumbing and mechanical closets that usually make a clean whole-home installation straightforward. Many owners here start with an equipment review before adding anything.
Las Flores
Compact lots and shared walls mean placement and drain access drive much of the design conversation. Point-of-use drinking water is a common first step.
Coto de Caza
Larger estates with high simultaneous demand, where sizing for flow matters as much as media selection. Multi-zone irrigation and equipment rooms are typical considerations.
Mission Viejo
Established homes where original galvanized or aging copper runs can influence taste and fixture condition independent of the delivered supply. Inspections often start at the water heater.
Rancho Santa Margarita
Hillside communities with variable static pressure, which affects both softener sizing and reverse-osmosis production rates. Pressure review is part of the assessment.
San Juan Capistrano
A mix of historic and newer homes, with some properties on different supply arrangements than surrounding tracts. We confirm the serving utility before discussing data.
Also serving
- Laguna Niguel — Hillside tracts with mature plumbing and frequent appliance-protection questions.
- Laguna Hills — Established neighborhoods where fixture scale is often the first noticed symptom.
- Aliso Viejo — Dense planned communities where equipment placement and drain routing shape the design.
- Lake Forest — Wide construction-era range, so equipment inspections vary considerably home to home.
- Irvine — Different serving utility than Ladera Ranch, so local data is confirmed before any recommendation.
- Dana Point — Coastal exposure adds fixture and appliance longevity to the conversation.
- San Clemente — Varied supply arrangements and older coastal housing stock.
- Trabuco Canyon — Semi-rural properties where some homes have private-source considerations.
- Foothill Ranch — Consistent tract construction that makes whole-home installations predictable.
- Talega — Newer master-planned homes with modern equipment closets and pre-plumb loops.
