Our range of water, waste water, irrigation and effluent testing services are designed to assist the agricultural, horticultural and food industries by helping our clients meet regulatory and environmental monitoring requirements and to identify potential problems and solve existing ones.
The following testing suites have been put together to meet the needs of the most common test enquiries that we receive, however there is a full range of extra tests that can be selected to meet any additional requirements you may have.
Drinking poor quality water can be the cause of illness.
An effective water sampling programme can prevent this, as chemical contaminants of drinking water often cause adverse health effects after prolonged periods of exposure. Reticulated water supplies from City and District Councils provide surety to the property gate through regular testing programmes but not at the kitchen tap.
ARL’s domestic and drinking water suite is suitable for analysing the quality of water from reticulated water supplies, wells, bores, streams, springs, reservoirs and collected rain water.
Why sample for domestic and drinking water?
The quality of irrigation water can have a profound influence on crop production, maturity and quality. To maximise your investment in plant and property, irrigation water quality should be evaluated before using a new water supply or purchasing a property.
Eurogap protocols recommend that irrigation water should be tested annually.
Why sample for irrigation?
Hard water is water that contains high levels of dissolved minerals. The most common hardness causing minerals are calcium and magnesium. Consequences of hard water include the formation of a hardness scale in the hot water heater (and other appliances), soap scum and unwanted taste in cooked foods. The hardness scale in hot water heaters can build up, blocking plumbing, leading to increased electric or gas bills and the early failure of the appliance.
Why sample for water softener?
FDE applied in the correct manner can save on the fertiliser bill to the tune of $290/ha/year. The nutrient value of effluent varies greatly from farm to farm and even with a farm over the season. Therefore sampling in Spring, Summer and Autumn, in conjuction with Overseer nutrient budget modelling is recommended to estimate long term nutrients applied to effluent block.

Which FDE analysis?
ARL offers two main analytical suites for FDE:

Nutrient enrichment (eutrophication) is due to the response in water to over-enrichment by nutrients from natural and "man-made" sources. This over-enrichment leads to the growth of rooted aquatic plants at the exclusion of other plants, algal mats, and deoxygenation which in turn can lead to stress of aquatic life. The main nutrients implicated in eutrophication are phosphorus and nitrogen. Nutrient sources that can contribute to eutrophication include municipal, industrial wastewater, agricultural runoffs, and urban runoffs.
Why sample for environmental impact?
Salinity is the measure of the total amount of salt in water and is measured by the conductivity of the water. Both sodium and chloride can cause potential for plant injury if in high enough concentrations in irrigation water.
Excess salinity in irrigation water can also cause excessive soil sodium levels which will lead to deterioration in soil structure.
Exploratory water wells should also be analysed for salinity to determine if water is fit to drink.
