Acres, from square miles

Lime from lead mine tailings containing 0.5% lead was applied at a rate of 10 metric tons per acre of soil and worked in to a depth of 20 cm. The soil density was 2.0 g/cm. To what extent did this add to the burden of lead in the soil There are 640 acres per square mile and 1,609 meters per mile. 

The Palo Verde nuclear power station near Phoenix, Arizona, was originally intended to have 10 nuclear reactors with a generating capacity of 1,243 megawatts each. As a result of public pressure, construction at Palo Verde was stopped after three operating reactors were completed. This installation is on 4,000 acres and is cooled by waste water from the city of Phoenix, which is nearby. An area of 4,000 acres is 6.25 square miles or 2.5 miles square. The power generating facilities occupy a small part of this area. 

Coal is Interspersed as individual beds within other types of sedimentary rock beds, including sandstones, limestones, clays, shales, and mixtures of these materials. The plant material that ultimately became coal deposits was accumulated in upland bogs, coastal or near-coastal swamps, or della plains. It is envisioned that the conditions were somewhat similar to the conditions existing today in the Okefenokce Swamp in Georgia or the Everglades of Florida. These areas may have varied from a few acres in several hundreds of square miles (hectares/square kilometers). Hence, the variation in ihe occurrence of coal as we find it today. 

But reduced energy use is only part of the story. Synthetic N, P, K are very soluble in water. This makes it easy for plants to use them, but synthetic fertilizer that is not taken up by the plants readily runs off or leaches out of the field into streams or into groundwater. The consequences have been serious. Excess nutrients in lakes and rivers cause algae to multiply and use up all the oxygen, resulting in death of fish and shellfish. Each summer, a 6,000-square-mile dead zone forms at the mouth of Mississippi River due to high levels of nitrogen and phosphorus drained from thousands of acres... 

The wood for the above mentioned Brazilian plant can be grown on a regenerable basis from about 90 square miles of forest (57,600 acres). Figure 7 is a block flow diagram showing the many process steps involved in Davy s wood gasification process. 

The Amazonian rain forest planet earth s foremost ecological disaster area, where thousands of acres and entire species are sacrificed forever on an around-the-clock basis to short-term slash-and-burn agriculture a two million square mile monument to human arrogance and stupidity. Most of us nave never seen it, most of us never will. From this the user. Users also seem to see the experience as real, not a "hallucination" in the usual sense of the word, and a portal to other worlds which exist alongside our own. ... 

The area of the Fayetteville Shale play is nearly double that of the Barnett Shale at 9000 square miles, with well spacing ranging from 80 to 160 acres per well and play zone thickness averaging between 20 and 2(X) feet. The gas content of the Fayetteville Shale has been measured at 60 to 220 scf/ton, which is less than the 300 to 350 scf/ton gas content of the Barnett Shale. The lower gas content of the Fayetteville has resulted in lower estimates of the original gas-in-place and technically recoverable resources 52 Tcf and 41.6 Tcf, respectively. 

To divide the public domain, surveyors created a series of principal meridians and baselines from which to measure (Fig. 117.1). Thirty-six square mile townships (93.3 sq km) were then surveyed from these fixed lines. A township s location could be easily defined in less than a sentence. For example, the shaded township in Fig. 117.2 is the second township north from the baseline, and the first east from the principal meridian, or Township 2 North, Range 1 East. Included in each township were 36 sections, each being one-square mile (2.6 km ), or 640 acres (259 ha)... 

Libby also estimated contamination resulting from release of 1 percent of one hundred days accumulated fission products at full power in a ten-thousand-thermal-kilowatt reactor "In an area of 1 to 5 square miles, crops would probably be unfit for use, within this same area perhaps one-half square mile would have to be temporarily evacuated, perhaps 50 to 100 acres would be unusable for about 2 years without thorough decontamination and in addition, of course, there might be a few acres near the site which would be more heavily contaminated." He reiterated that the damage would be influenced greatly by terrain and wind pat-... 

The interpretation of the effects of such drift, particularly its potential for adverse effects on human health, is dependent on some of the parameters of environmental behavior shown on Table VIII. The dose is given at 2 lbs/acre and translated into a deposit level of 20 mg/square foot, which is more useful in the interpretation of exposure data. The figures given for the deposit amount from spray drift at 100 yards and 1/2 mile are the figures for drift from a coarse spray on flat land for small target areas and are average drift amounts. The figure of 20 mg/kg is the NOEL for 2,4-D.
