Seite 52 - ... the well. 5. A suitable exposure of the edge of the porous stratum, so that it may take in a sufficient supply of water. 6. An adequate rainfall to furnish this supply. 7. An absence of any escape for the water at a lower level than the surface of the well.
Seite 52 - A like impervious bed above, to prevent escape upward, for the water, being under pressure from the fountain head, would otherwise find relief in that direction.
Seite 28 - The greatest annual average- — from 62 to 63 inches — is in the southwestern counties, bordering on the Gulf of Mexico. Another region of heavy precipitation is found over the mountainous (north-central and north-eastern) portions, where it ranges from 47 to 54 inches per annum. The region of least precipitation is near the center of the State, where the annual average is about 46 inches. The precipitation is practically all rain. ' Snow occurs on an average twice each winter in the northern...
Seite 216 - WJ McLendon's well, near Chattahoochee River; depth 465 feet. Record: Sand and clay, 20 feet; marl with shell, 65 feet; beds of sand and marl, 15 to 25 feet thick, alternating, to 380 feet; hard rock, 2 feet; sand to 445 feet. Water at this point flowed 12 gallons per minute, but has decreased to 4 gallons.
Seite 310 - ... constituents, or those which have an alkaline reaction and (2) contain sulphuric, muriatic, or nitric acid ions along with boric or silicic acid ions, both classes being present as predominating constituents, where it can be proved that the alkalinity is largely due to the presence of borates or silicates. Acid waters are those which have an acid reaction, and contain either sulphuric or muriatic acid ions in predominating quantities.
Seite 42 - There is no doubt but that the rate of flow of water through the superficial layers of rocks is increased by the existence of cracks and fissures due to the contraction and expansion from changes of temperature, to frost, crustal movements, etc., but it must be borne in mind on the other hand that at considerable depths below the surface these cracks and fissures are likely to be closed by the creep of the rock, and by the deposition of mineral matters from the circulating waters, so that after all...
Seite 292 - Silica (SiO3) 6.08 41.92 The analyses show these two waters to differ very materially. In the first the salts are chlorides only, with the exception of a small amount of sulphate of iron ; in the second the salts are chlorides, sulphates, and carbonates. In both, on the other hand, the salts of magnesium and iron and common salt predominate. 'Expressed by analyst in grains per gallon and hypothetical combinations : recomputed to ionic form and parts per million at U. S.
Seite 310 - Alkaline waters are defined as those giving an alkaline reaction* and containing carbonic or bicarbonic acid ions in predominating quantities, and those giving an alkaline reaction and containing boric or silicic acid ions in predominating quantities, where it can be proved that the alkalinity is due to the presence of berates or silicates.
Seite 310 - ... or nitrated for the alkaline-saline and saline classes; and as sulphated or muriated for the acid class. If any basic element is prominent in the water this fact may be indicated by prefixing its name, (sodic, lithic, potassic, calcic, magnesic, ferruginous, or aluminic) to the regular class name. If any basic or acid constituent is prominent therapeutically but not chemically, this fact may be indicated by adding or affixing its name (arsenic, bromic, iodic, boric, siliceous, ferruginous, etc.)...
