Dr. Marie Archbold:

There are different frequencies for monitoring nationally. Some of the monitoring points are monitored every month. Some are monitored once every three months. Ecological monitoring takes place around the country once every three years.

If there is a problem, it comes down to the characterisation risk assessment approach involving all the monitoring data and information. That is all pulled together and the EPA then assesses where water bodies are at risk of impact from agriculture. That is put into maps and LAWPRO is tasked with going out in those priority areas for action, getting boots on the ground and seeing what exactly is the problem in the river. That involves more monitoring. If there is a problem, a referral goes out to ASSAP.
