* 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.

* Tests should be performed within 48 hours of a rain event, when the soil is already near or at field capacity.

* Make a minimum of seven (7) measurements for each test location (i.e., each test pit or borehole).

* Test locations should be spaced equidistant from one another.

* To calculate the median infiltration rate of the native soil, discard the highest and lowest values obtained from each test location (i.e. test pit or borehole) and calculate the median from the remaining measurements.

Additional tests should be conducted at 1.5 metres depth below the proposed bottom elevation of the practice if there is significant variability in soil texture, geology, water table elevation, top of bedrock elevation or bedrock type compared to conditions at the proposed bottom elevation. Excessive testing and disturbance of the site prior to construction is not recommended.<ref>Christopher B. Burke Engineering LLC. (2009).
