Why real-time testing matters

Changing freshwater conditions may contribute to issues including skin irritation, stomach upset and exposure to pollutants or toxins associated with blue-green algae.

Heavy rainfall, agricultural runoff, warmer temperatures and environmental conditions can all impact water quality within a short period of time.

Designed for swimmers, families, paddleboarders and dog owners, the SwimSense Field Test Kit provides additional real-time insight at the water’s edge to help support more informed outdoor adventures.

In Collaboration With AWE Environmental Services

Developed in collaboration with AWE Environmental Services — specialists in freshwater monitoring, algae management and environmental water solutions — the SwimSense Field Test Kit combines real-time water insights with freshwater toxin awareness associated with blue-green algae conditions.

Designed for swimmers, families and outdoor water users, the kit helps provide additional insight into changing freshwater conditions before entering the water.

What the results can indicate

SwimSense is designed to give a quick snapshot of changing water conditions at the time of testing. While these strips are not a laboratory analysis or a direct bacteria test, unusual readings can sometimes indicate conditions that may be less suitable for swimming, paddling, children playing near the water, or dogs entering the water.

Natural waters are constantly changing due to rainfall, runoff, temperature, wildlife activity, tides, agricultural pollution, sewage overflows, algae growth, and reduced water flow. Your results can help provide extra awareness before entering the water.

Elevated readings may indicate:

  • Increased organic pollution or runoff after heavy rain
  • Poorer water quality conditions in slower-moving or stagnant water
  • Potential irritation risks for skin, eyes, ears, or cuts
  • Conditions that may contribute to stomach upsets if water is swallowed
  • Environmental changes that can support algae growth in some conditions
  • Water that may be less suitable for children or pets, who can be more sensitive to pollutants

Blue-Green Algae Awareness

Some environmental conditions — such as warm temperatures, nutrient pollution, stagnant water, and elevated ammonia or nitrate levels — can increase the likelihood of blue-green algae (cyanobacteria) growth.

Blue-green algae can be harmful to humans and especially dangerous for dogs, who may ingest toxins while swimming or drinking water. Symptoms can range from mild irritation to more serious illness.

SwimSense does not directly test for blue-green algae toxins unless used alongside dedicated algae testing products, but your results may help indicate conditions where extra caution and visual checks are sensible.

A Helpful Indicator — Not A Definitive Safety Guarantee

SwimSense is intended to support informed decisions and encourage awareness of changing water conditions. Results should always be considered alongside:

  • Local guidance and warning signs
  • Visible water conditions
  • Weather and rainfall
  • Water smell, colour, or surface scum
  • Personal judgement

Many open water swimmers use SwimSense as an added layer of confidence and awareness — especially after storms, near discharge points, during warmer weather, or when swimming somewhere unfamiliar.

*Results should always be considered alongside local guidance, weather conditions and your own judgement before entering the water.* (See our terms and conditions)

FAQ's

How long do the tests take?

Most SwimSense results develop within minutes, allowing users to quickly assess changing conditions before entering the water.

Who is SwimSense Field Kit designed for?

SwimSense was created for:

  • Wild swimmers
  • Open water swimmers
  • Paddleboarders
  • Surfers
  • Triathletes
  • Families enjoying natural water
  • Dog walkers near lakes and rivers

Anyone wanting greater awareness of changing water conditions may find it useful.

What can elevated ammonia or nitrate readings indicate?

Higher readings may suggest increased organic pollution or runoff entering the water. This can happen after heavy rain, flooding, agricultural runoff or wastewater discharge events.

These readings do not confirm harmful contamination, but they may indicate conditions where extra caution is appropriate.

Does SwimSense detect blue-green algae?

SwimSense Field Test Kits include dedicated blue-green algae toxin tests designed to help detect toxins associated with harmful algal blooms (cyanobacteria).

In addition, some environmental indicators within the wider SwimSense testing system — such as elevated nutrients, ammonia levels, warmer stagnant water conditions, and reduced water movement — may help highlight conditions where algae growth is more likely.

While no field test can guarantee complete water safety, these tools can provide valuable real-time awareness to support informed decisions before entering the water.

Always avoid water with visible surface scum, unusual colouring, strong odours, or official algae warnings, and take extra care with children and dogs around suspected algae blooms.

Is blue-green algae dangerous for dogs?

Yes. Blue-green algae toxins can be especially dangerous for dogs if ingested while swimming or drinking water.

If you suspect algae is present:

  • Keep dogs out of the water
  • Prevent them licking wet fur
  • Follow local guidance and warning signs

How accurate is SwimSense?

SwimSense is designed to provide fast, accessible indicator results for outdoor water users. It is not intended to replace laboratory analysis or official monitoring.

Results should be viewed as a helpful snapshot of conditions at the time of testing.

What does SwimSense test for?

SwimSense tests a range of water quality indicators that can help provide a quick snapshot of changing water conditions at the time of testing. Parameters may include pH, nitrates, nitrites, chlorine, metals, hardness, alkalinity, ammonia and other environmental indicators depending on the strip type.

Does SwimSense test for E. coli or bacteria?

No. SwimSense is not a bacteria or laboratory test and does not directly measure E. coli, enterococci, viruses or all contaminants.

However, certain elevated indicators — particularly ammonia, nitrates and nitrites — may sometimes suggest increased organic pollution, runoff, wastewater contamination or environmental conditions that can be associated with poorer water quality.

These readings do not confirm the presence of harmful bacteria, but they may indicate conditions where extra caution could be sensible, especially after heavy rainfall, sewage overflow events, flooding, or in stagnant water conditions.

Results should always be considered alongside local guidance, visible water conditions and personal judgement.

Can SwimSense tell me if water is completely safe?

No natural water can ever be guaranteed completely safe. SwimSense is designed as an awareness and decision-support tool to help users better understand changing water conditions.

Results should always be considered alongside:


  • Local guidance

  • Weather and rainfall

  • Visible water conditions

  • Official warnings

  • Personal judgement

Why can water conditions change so quickly?

Open water conditions can change within hours due to:

  • Heavy rainfall
  • Agricultural runoff
  • Sewage overflows
  • Tides and currents
  • Warm temperatures
  • Wildlife activity
  • Low water flow

This is why real-time indicator testing can be useful, especially after storms or in unfamiliar locations.

Important Information

SwimSense provides rapid indicator results designed to support awareness of changing water conditions. It is not a laboratory-certified analysis and does not directly test for bacteria such as E. coli or all possible contaminants.

Water conditions can change quickly due to weather, runoff, tides, wildlife activity, and other environmental factors. Results should always be considered alongside local guidance, visible conditions, and personal judgement before entering the water.

SwimSense is intended as an informational tool only and should not be relied upon as a guarantee of water safety. By using this product, users accept responsibility for their own decisions and water activities.
