Monitoring nitrogen in rivers
Nitrogen in water is an essential nutrient for the growth of plants and algae. Whilst nitrogen is naturally present at low levels in rivers, excessive…
Guidance
Monitoring total nitrogen in lakes
Nitrogen is an essential nutrient for the growth of plants and algae. Whilst nitrogen is present naturally in lakes, concentrations may be elevated due to…

Monitoring periphyton in rivers
Periphyton is the brown or green slime that grows on stones, wood or any other stable surfaces in streams and rivers. In some situations, it…
Guidance
Monitoring phosphorus in rivers
Phosphorus is an essential nutrient for the growth and development of plants and animals. It occurs naturally as phosphate bound to rocks and soil, and…
Guidance
Monitoring total phosphorus in lakes
Phosphorus is an essential nutrient for the growth and development of plants and animals. However, elevated phosphorus concentrations in a lake can lead to eutrophication,…
