Our Testing Parameters

Discover the key parameters we use in our water testing and understand how they impact our results. These essential tests provide us with valuable insights into the quality and safety of our water.

Air Temperature

Refers to the temperature of the air above the water. We test this because it affects water temperature and ecosystem health

< 21°C

Optimal

> 21°C

Suboptimal

Water Temperature

Refers to the temperature of the water. We test this because it affects aquatic life and chemical processes.

< 21°C

Optimal

> 21°C

Suboptimal

Water Clarity

Is the transparency of water. We test this because it Indicates the presence of suspended particles.

> 30cm

Optimal

< 30cm

Suboptimal

Turbidity

Is the cloudiness or haziness of water. We test this because it measures the concentration of suspended particles.

< 10 NTU

Optimal

> 10 NTU

Suboptimal

pH

Is a measure of the acidity or alkalinity of water. We test this because extreme pH levels can be harmful or lethal to wildlife.

7 pH

Optimal

< 5 pH or > 9pH

Suboptimal

Dissolved Oxygen

I the amount of oxygen dissolved in water. We test this because it is essential for aquatic life survival.

6-9 mg/L

Optimal

<2 mg/L

Suboptimal

Nitrite

Is a form of nitrogen in water. We test this because it is an indicator of pollution and water quality.

< 0.1 mg/L

Optimal

> 0.2 mg/L

Suboptimal

Nitrate

Is another form of nitrogen in water. We test this because it indicates nutrient levels and potential eutrophication.

< 1 mg/L

Optimal

> 5 mg/L

Suboptimal

Phosphorus

We test nutrient levels to assess pollution and the risk of eutrophication. Eutrophication occurs when excessive nutrients in a river lead to algae blooms, which can harm aquatic life.

< 0.02 mg/L

Optimal

> 0.8 mg/L

Suboptimal

Phosphate

Is a form of phosphorus in water. We test this because it assesses nutrient levels and potential eutrophication.

< 0.02 mg/L

Optimal

> 0.05 mg/L

Suboptimal

Pollution

Discover the latest pollution events data on our pollution dashboard.
