[[File:Test_pit.jpg|thumb|Infiltration testing should be carried out at relevant stages down through the profile of a test pit.]]
The number of test pits or soil borings varies depending on site conditions and the proposed development plan. General guidelines are as follows:
The number of test pits or soil borings varies depending on site conditions and the proposed development plan. General guidelines are as follows:
* Tests must be conducted within 10 m of the infiltration practice footprint area.
* Tests must be conducted within 10 m of the infiltration practice footprint area.
* Where multiple test are carried out, they should be planned equidistant and mapped accordingly.
* Where multiple test are carried out, they should be planned equidistant and mapped accordingly.
'''The recommendations above are guidelines'''
Additional tests should be conducted if local conditions indicate significant variability in soil types, geology, water table levels, depth and type of bedrock, topography, etc. Similarly, uniform site conditions may indicate that fewer test pits are required.
