Worried About Contaminants in Your Drinking Water? Here’s What You Need to Know

Oct 25, 2024

Clean drinking water matters every day. It affects what your family drinks, cooks with, makes coffee with, fills bottles with and uses around the kitchen.

Most Brisbane and Gold Coast homes connected to town water receive treated drinking water, but that does not mean every household is happy with the taste, smell or level of filtration at the tap. Some customers want to reduce chlorine taste and odour. Others are concerned about sediment, older pipework, tank water, bore water, microbes, heavy metals or PFAS.

The right solution depends on your water source and what you want to reduce. JR Gas & Water can help compare suitable water filters, including under-sink drinking water systems, carbon filtration, reverse osmosis, UV treatment and whole-home filtration options for Brisbane, the Gold Coast and nearby South East Queensland homes.

Quick Answer

Common drinking water concerns include chlorine taste and odour, sediment, heavy metals from older plumbing, microbial contamination in untreated water sources, and PFAS in some higher-risk locations.

For most town water homes, an under-sink carbon filter is a practical starting point for better taste and odour. For higher-level drinking water filtration, reverse osmosis may be worth comparing. For rainwater, tank water or bore water, sediment filtration and UV treatment may be required depending on testing and household use.

The best filter is not the most expensive one. It is the one matched to your water source, contaminant concern, flow rate, maintenance expectations and installation setup.

What Can Be in Drinking Water?

Drinking water quality depends on the source, treatment process, pipework and property setup.

Common concerns can include:

Chlorine taste and odour
Sediment, sand, rust or grit
Disinfection by-products
Heavy metals from older plumbing or site contamination
Microbial contamination in untreated water sources
PFAS in some affected areas
Pesticide or chemical residues in certain water sources
Hardness minerals
Organic matter from tanks or catchments
Unpleasant taste, smell or colour

Not every home has all of these issues. A house on treated mains water usually has different risks to an acreage property using rainwater tanks, bore water or pump-fed supplies.

Chlorine Taste and Odour

Chlorine is commonly used to disinfect drinking water because it helps manage harmful microorganisms as water moves through the supply network.

For many households, the issue is not safety but taste and smell. Some people notice a swimming-pool-like odour, especially in drinking water, tea, coffee and ice.

Best Filter Options for Chlorine Taste

Carbon filtration is usually the best starting point for chlorine taste and odour.

Good options may include:

Under-sink carbon filters
Carbon block filters
Whole-home carbon filtration
Filtered water taps
Premium drinking water systems with carbon stages

A quality carbon filter can make drinking water taste cleaner and more pleasant without needing a complex system.

Sediment, Rust and Grit

Sediment can appear as small particles, cloudy water or grit around taps and appliances. It may come from older pipework, plumbing work in the street, rainwater tanks, bore water or internal property plumbing.

Sediment is more common in:

Older homes
Tank water systems
Bore water setups
Acreage properties
Homes with ageing internal pipework
Properties after nearby mains works
Pump-fed water systems

Best Filter Options for Sediment

Sediment filtration is usually the first stage.

Suitable options may include:

Sediment pre-filters
Whole-home sediment filters
Multi-stage filtration systems
Tank water filtration
Pump-compatible filtration setups

For tank, bore or acreage homes, sediment filtration is often used before carbon, UV or reverse osmosis systems.

Heavy Metals in Drinking Water

Heavy metals such as lead can be a concern where older plumbing, fittings or site conditions affect water quality. This is usually more relevant in older homes, properties with ageing pipework or sites with known contamination concerns.

Heavy metals are not usually solved by a basic taste filter unless the cartridge is specifically rated for that contaminant.

Best Filter Options for Heavy Metals

Depending on the contaminant and water source, suitable options may include:

Reverse osmosis
Specialist carbon block cartridges
Ion exchange media
Multi-stage drinking water filters
Point-of-use under-sink filtration

If heavy metals are a specific concern, water testing is the best starting point. That helps avoid choosing a filter that improves taste but does not target the actual issue.

Microbial Contaminants

Microbial contamination can include bacteria, parasites or other microorganisms. This is usually a bigger concern for untreated or privately managed water sources rather than properly treated town water.

Higher-risk water sources can include:

Rainwater tanks
Bore water
Creek or dam-fed systems
Untreated private supplies
Poorly maintained tank water systems
Properties with animal or roof runoff exposure
Water sources affected by flooding or contamination

Best Filter Options for Microbes

The right setup depends on the water source and testing results.

Common treatment stages may include:

Sediment filtration
Carbon filtration
UV water treatment
Whole-home tank water filtration
Specialist treatment for private supplies

UV treatment can be useful for microbial control, but it needs pre-filtration. If water is cloudy or full of sediment, particles can interfere with UV performance.

PFAS and Forever Chemicals

PFAS, often called forever chemicals, are persistent manufactured chemicals that can enter the environment through industrial use, firefighting foam, contaminated land, landfill leachate and some water sources.

Not every home has a PFAS issue, but some households want additional drinking water protection, especially if they use private bores or live near known investigation areas.

Best Filter Options for PFAS

For PFAS reduction, look for systems specifically designed and rated for that purpose.

Common options include:

Reverse osmosis
Activated carbon systems rated for PFAS
Ion exchange resin systems
Multi-stage under-sink drinking water systems

Boiling water does not remove PFAS. A basic taste filter should not be assumed to remove PFAS unless it has suitable performance information.

For customers concerned about PFAS, JR Gas & Water can help compare suitable water filters and drinking water filtration options.

Whole-Home Filtration

A whole-home water filter is installed on the main water line before water reaches taps, showers, bathrooms, laundries and appliances.

This type of system can be useful when the issue affects more than one tap or when the property has sediment, taste or tank water concerns.

Best Suited To

Whole-home filtration may suit:

Families wanting filtered water throughout the house
Homes with sediment issues
Tank water properties
Acreage homes
Homes with taste and odour concerns across multiple taps
Properties wanting filtration before fixtures and appliances

What It Can Help With

Depending on the system, whole-home filtration may reduce:

Sediment
Rust particles
Dirt and grit
Chlorine taste and odour
Some organic compounds
Tank water particles
General water clarity issues

Whole-home filtration needs to be sized properly so it does not restrict water flow or become difficult to maintain.

Under-Sink Drinking Water Filters

Under-sink filters are one of the most practical options for households that mainly want better drinking water.

They are usually installed under the kitchen sink and connected to a dedicated filtered tap or 3-way mixer.

Best Suited To

Under-sink filters may suit:

Families wanting better-tasting drinking water
Homes connected to treated town water
Customers wanting filtered water for cooking
Kitchens with enough under-sink space
Households reducing bottled water use
Tea, coffee and ice use
Apartments and townhouses

Main Benefits

Under-sink systems are popular because they are targeted and convenient.

Benefits include:

Filtered water where you drink it most
Less need for bottled water
Cleaner kitchen bench than filter jugs
Good taste and odour improvement
Practical maintenance access
Lower complexity than whole-home systems

For many Brisbane and Gold Coast homes, this is the best starting point.

Reverse Osmosis Drinking Water Systems

Reverse osmosis, often called RO, is a higher-level drinking water filtration method. It pushes water through a fine membrane to reduce dissolved solids and many smaller contaminants.

Best Suited To

Reverse osmosis may suit:

Homes wanting high-level drinking water filtration
Households concerned about dissolved contaminants
Customers comparing fluoride, heavy metal or PFAS reduction
Properties with specific water quality concerns
Families wanting a dedicated drinking water tap
Customers wanting very clean-tasting water

Things to Consider

RO is effective, but it needs more maintenance than a basic filter.

Check:

Under-sink space
Filter replacement schedule
RO membrane replacement
Water pressure
Drain connection
Flow rate
Whether remineralisation is preferred
Ongoing cartridge cost

RO can reduce minerals as well as contaminants, so some customers prefer systems with remineralisation for taste.

UV Water Purification

UV treatment uses ultraviolet light to help inactivate microorganisms in water.

It is most useful where microbial contamination is a concern, especially for rainwater tanks, bore water and untreated private supplies.

Best Suited To

UV systems may suit:

Rainwater tank homes
Acreage properties
Bore water supplies
Rural homes
Untreated private water sources
Properties with microbial testing concerns

Important Limitation

UV does not remove sediment, chlorine, heavy metals, PFAS or dissolved solids. It is usually part of a multi-stage system, not a standalone solution for every contaminant.

For UV to work properly, water should usually be filtered first to reduce sediment and cloudiness.

Carbon Block Filters

Carbon block filters are one of the most common and practical water filtration options for homes connected to town water.

They are especially useful for improving taste and reducing chlorine odour.

Best Suited To

Carbon block filters may suit:

Town water homes
Families wanting better-tasting drinking water
Under-sink filter taps
Coffee and tea drinkers
Households wanting a simple filtration setup
Customers reducing bottled water use

What They Can Help With

Depending on the cartridge, carbon block filters may reduce:

Chlorine taste and odour
Some chemicals affecting taste
Fine sediment
Some organic compounds
Selected contaminants where rated

Always check the cartridge rating if you are targeting a specific contaminant.

Tap Filters and Filter Jugs

Tap filters and filter jugs can be useful for short-term or low-cost taste improvement, but they are limited compared with installed systems.

Best Suited To

Filter jugs may suit:

Renters
Temporary use
Low-volume drinking water
Budget-conscious customers
People wanting basic taste improvement

Limitations

They may have:

Small capacity
Slow filtration
Frequent cartridge changes
Limited contaminant reduction
No whole-home benefit
No protection for showers, appliances or other taps

For daily family use, an under-sink system is usually more convenient.

Best Filter Type by Concern

Concern Best Filter Types to Compare
Chlorine taste and odour Carbon block or under-sink carbon filter
Sediment, rust or grit Sediment filter or whole-home pre-filter
Heavy metals Reverse osmosis or specialist-rated cartridge
PFAS Reverse osmosis, PFAS-rated carbon or ion exchange
Microbes in tank water Sediment filtration plus UV treatment
Better drinking water taste Under-sink carbon filter
Whole-home water quality Whole-home sediment and carbon filtration
Tank, bore or acreage water Custom filtration based on testing

Why Water Source Matters

The best filtration system depends on where your water comes from.

Town Water

Most Brisbane and Gold Coast homes use treated town water. Common goals for these homes include:

Better taste
Less chlorine smell
Filtered water for drinking
Reduced sediment from internal pipework
Less bottled water use
Improved water for cooking and coffee

For town water homes, an under-sink carbon filter is often the most practical first step.

Rainwater Tanks

Rainwater can collect debris from roofs, gutters and tanks. It may also be affected by animals, leaves, dust and organic matter.

Tank water may need:

Sediment filtration
Carbon filtration
UV treatment
Pump-compatible filtration
Regular tank and gutter maintenance
Water testing if used for drinking

Bore Water

Bore water can vary significantly by location. It may contain minerals, sediment, iron, hardness, odour, salts or other contaminants.

Bore water should be tested before selecting a filtration system.

Acreage and Pump-Fed Systems

Acreage homes may use tanks, pumps, bores or mixed supplies. These setups often need a more tailored approach.

JR Gas & Water can help compare filtration options alongside water pumps for properties where water supply and pressure are part of the same issue.

Professional Installation Matters

Water filters work best when they are selected and installed properly.

Professional installation can help avoid:

Leaks under the sink
Poor water flow
Incorrect cartridge setup
Wrong filter for the water source
Poor UV performance
Bypassed filtration
Difficult filter replacement access
Pressure issues
Non-compliant plumbing connections
Damage to cabinetry or fixtures

For whole-home filters, UV systems, reverse osmosis and permanent under-sink systems, plumbing support is usually the safer option.

JR Gas & Water can help through the Brisbane plumber service or by reviewing photos and details through the quote request page.

Maintenance: The Step People Forget

A filter is only effective if it is maintained.

Filter maintenance may include:

Changing cartridges on schedule
Replacing UV lamps annually where required
Changing RO membranes as recommended
Checking for leaks
Cleaning pre-filters
Checking flow rate
Recording replacement dates
Using genuine or suitable replacement cartridges
Testing private water sources when needed

A filter left too long can lose performance, reduce flow and give a false sense of protection.

Signs You May Need a Water Filter

You may benefit from a water filter if you notice:

Chlorine smell or taste
Cloudy water
Sediment in taps or appliances
Rust-coloured water
Poor-tasting tea or coffee
Frequent bottled water use
Tank water concerns
Bore water use
Family members avoiding tap water
Known local contamination concerns
Water used for baby bottles or cooking
Desire for better daily drinking water

If the concern is health-related or source-specific, water testing may help choose the right system.

FAQs About Drinking Water Contaminants

What are the most common drinking water concerns in Australian homes?

Common concerns include chlorine taste and odour, sediment, disinfection by-products, heavy metals from older plumbing, microbial contamination in untreated water sources, and PFAS in some affected areas.

What is the best filter for chlorine taste?

A carbon block or under-sink carbon filter is usually the best starting point for reducing chlorine taste and odour in treated town water.

Does boiling water remove chemicals?

Boiling water can help kill many microorganisms, but it does not remove chemical contaminants such as lead, PFAS, chlorine by-products or dissolved solids. Some contaminants may become more concentrated as water evaporates.

Do I need reverse osmosis?

Reverse osmosis may be worth considering if you want higher-level drinking water filtration or are concerned about dissolved contaminants, PFAS, fluoride or heavy metals. For basic taste and odour improvement, a carbon filter may be enough.

Do UV filters remove chemicals?

No. UV treatment targets microorganisms. It does not remove chemicals, sediment, PFAS, heavy metals or chlorine. UV is usually paired with sediment filtration and other treatment stages.

Are water filter jugs enough?

Filter jugs can improve taste for small amounts of drinking water, but they are limited. For regular family use, an under-sink filter or whole-home system is usually more practical.

How often should water filters be replaced?

Replacement timing depends on the system, cartridge size, water quality and household use. Many cartridges are replaced every 6 to 12 months, while RO membranes and UV lamps follow their own schedules.

Can JR Gas & Water help choose the right filter?

Yes. JR Gas & Water can help compare water filters based on your water source, kitchen layout, household size and filtration goals.

Final Thoughts

Drinking water concerns can range from simple taste and odour issues to more serious contamination risks in private or affected water sources. The right response is to understand your water source, identify your main concern, and choose a filtration system designed for that job.

For most town water homes, an under-sink carbon filter is a practical first step. For higher-level drinking water filtration, reverse osmosis may be worth comparing. For tank, bore or acreage water, sediment filtration, UV treatment and water testing may be needed.
