the first project i tackled was to excavate my future home’s basement. the photos show before, during and after on my wooded property. the excavation was 56’ x 36’ x 6’ deep, or about 12,000 cubic feet of earth moved with the tractor! as you can see, the ground is a combination of sand, gravel and rock.
this is a flushable spin down sediment filter for well water that filters out sand, particles, and sediments without the need to replace filter cartridges. with 100 mesh high-impact molded polyester mesh filter screen to effectively block out sediments with size larger than 149 microns. ideal for household well water application.
the only materials you will need to begin removing rocks from the yard will be a shovel, a bucket, and a screen or net that will be used for separating rocks from dirt. to remove rocks from the soil by hand, you will want to follow these steps: 1. build a separator screen using expanded metal or a chain link fence.

in the unsaturated zone, the voids—that is, the spaces between grains of gravel, sand, silt, clay, and cracks within rocks—contain both air and water. although a lot of water can be present in the unsaturated zone, this water cannot be pumped by wells because it is held too tightly by capillary forces .
softening, filtration and chlorination have been found ineffective for reducing concentrations of tce to non-hazardous levels (robeck and love, 1983). other methods are required for remediation of water contaminated with tce if such water is to be used for human consumption. the purpose of this paper is to: 1) present a synopsis of physico-

resource depletion is the consumption of a resource faster than it can be replenished. natural resources are commonly divided between renewable resources and non-renewable resources. use of either of these forms of resources beyond their rate of replacement is considered to be resource depletion. the value of a resource is a direct result of its availability in nature and the cost of extracting the resource, the more

filling an in-ground swimming pool can lead to all sorts of unexpected problems. once the pool is empty, it may become buoyant while sitting in the ground. if the soil conditions are right, the pool can actually begin to 'float' up out of...
4. iron filings are attracted by a magnet. this is a physical property of iron but not of most other materials, including sand. how could you use this difference in physical properties to separate a mixture of iron filings and sand?
the use of a sand embedment is advised on pressurized lines to minimize damage caused by moving soil that has a higher clay content. pressurized lines can also move when pumps kick on and off. sand bedding 4 inches (10.2 cm) on all sides of the lines will prevent any sharp rocks from the ground or the backfill from wearing holes in the pipe

the drilling and transport of brine solutions can disrupt existing ecosystems and well casings, pipelines, and storage tanks are subject to corrosion due to the high salinity content of the solutions that they are exposed to, which can lead to leaks and contamination of adjacent bodies of water (new york state division of mineral resources, 1988) currently, there is no economically plausible plan to clean up
