What is the objective of pit method ground water test When the soil type not recommended
The objective of the pit method groundwater test is to determine the water table depth and the quality of groundwater in the area where a proposed construction project is planned. This information can help engineers and builders determine whether there is a risk of flooding, whether the soil can support the weight of a structure, and whether the groundwater is safe to use for construction and other purposes. If the soil type is not recommended for construction, the pit method groundwater test can also help identify alternative areas where construction may be feasible.
The objective of the pit method groundwater test is to determine the suitability of the soil for on-site wastewater treatment and disposal when the soil type is not recommended. This test helps in assessing the ability of the soil to absorb and treat wastewater effectively.
Here are the step-by-step instructions for conducting a pit method groundwater test:
1. Dig a hole in the ground that is about 2 feet wide and 2 feet deep. Ensure that the hole is located in an area where the soil type is not recommended for wastewater treatment.
2. Allow the hole to fill with water naturally by natural precipitation or by adding water manually until it is completely filled.
3. Measure the time it takes for the water to drain into the soil. This can be done by observing the water level drop at regular intervals and recording the time.
4. Measure the depth of the water remaining in the hole after 24 hours. This will indicate the groundwater level.
5. If the water in the hole drains too slowly or the groundwater level is too high, it suggests that the soil is not suitable for wastewater treatment and disposal.
It is important to note that the pit method groundwater test is a basic preliminary assessment. For a more accurate evaluation of the soil suitability, it is recommended to consult with a professional soil scientist or engineer.
