Question:
Is there a risk of the sampler contaminating the samples?

There is a risk of transferring eDNA on your boots, equipment etc. as you move from pond to pond. You should make sure that you never go in the water when sampling a pond. When possible take your eDNA samples before you do other surveys. Exceptionally muddy/wet conditions may also increase the chances of contamination due to splashing of GCN containing water or mud onto clothing/boots or equipment.
