While in the field, running a stabilization survey at Wupatki National Monument, the writer and Phillip Van Cleave, an assistant, encountered a site which illustrates another method utilized by the prehistoric Indians in dealing with the problem of water supply in this arid region.

From the time early in the nineteenth century when the ruins now known as Gran Quivira National Monument were rediscovered, speculation as to the source of the water supply has been rife. Many are the theories to account for the presence of this pueblo ruin in the midst of an expansive waterless region. These theories range from an assumption of the former existence of springs, now long dried up, to tales of marvelous aqueducts which brought water from a spring in the Gallinas Mountains to the east, a distance of fifteen miles. Recently, researches have brought to light new data in explanation of this apparent condition. It is, therefore, the purpose of this paper to assemble all of the available evidence, to evaluate and present it.

Approximately 60,000 tons per day of waste from taconite mining, tailing, are added to the west arm of Lake Superior at Silver Bay. Tailings contain nearly the same amount of quartz and amphibole asbestos, cummingtonite and actinolite in fibrous form. Cummingtonite fibres from 0.01μm in length have been found in the water supply for Minnesota municipalities.The purpose of the research work was to develop a method for asbestos fibre counts and identification in water and apply it for the enumeration of fibres in water samples collected(a) at various stations in Lake Superior at two depth: lm and at the bottom.(b) from various rivers in Lake Superior Drainage Basin.

Studies of bacterial behavior in many environments have shown that most organisms attach to surfaces, forming communities of microcolonies called biofilms. In contaminated medical devices, biofilms may serve both as reservoirs and as inocula for the initiation of infections. Recently, there has been much concern about the potential of dental units to transmit infections. Because the mechanisms of biofilm formation are ill-defined, we investigated the behavior and formation of a biofilm associated with tubing leading to the water syringe of a dental unit over a period of 1 month.
