我想尝试在林地地区建造一个井型结构。这片林地主要生长着白桦树和梧桐树，在距离水井理想位置约80英尺的沼泽地上有一条浅溪流，但它可能会移动。

我的想法是，由于水的普遍存在，很可能通过自然的渗透过程在地下形成一个水体。

所以我的问题如下:

1)如果我挖这口井，我可能会遇到水吗?

2)我要挖多深才能到达水或不透水的地面?< / p >

The point I am getting to, is that all gas stations in Colorado have to be measured every three months and the results sent to the State. I would suggest that you check for a gas station near where you live and get a recent published water report that you can study. One of the maps is a water table depth map. The map will have a contour map with the depth below surface contours and arrows perpendicular to contour lines that show the direction of groundwater flow.

I would suggest for you to see if your State or Provence has a similar contamination monitoring program. This would give you an idea how the water table behaves in your area. If you go to your nearest gas station and look for circular steel plates about 6 inches in diameter placed flush on the ground around the tanks, gas pumps, and parking lot, then you will know if the station is monitored. The top of the plate has a filled in triangle with the triangle points touching the circle circumference. Sometimes the plate has a warning that says "DO NOT FILL". The the steel plate and map symbol looks like Unicode symbol U1F7D5.

If the groundwater is discharging to the stream you may be looking at relatively shallow depth to water when you are in the valley that close. It depends a lot on the amount of rainfall that recharges the groundwater and the topography, as well as the soil and rock type. It is impossible to say from the information you have given on what the depth to bedrock will be.

That being said, these shallow flow systems can have poor quality water and can even be affected by contaminants from the stream (e.g. when it floods).
