* 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.

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

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

* To calculate the median value for each test location, 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.  

* 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 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. Excessive testing and disturbance of the site prior to construction is not recommended.<ref>Christopher B. Burke Engineering LLC. (2009).

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).
