Richard P. McCulloh reports that a sidewalk fracture in a residential neighborhood not far north of the Baton Rouge fault in southern East Baton Rouge Parish exhibits what may be transcurrent or strike-slip displacement of approximately 10 cm or 3.9 in, with a left-lateral sense of separation. The fracture, which strikes approximately N 72 degrees E, is subparallel to the sidewalk and transects portions of 6 sidewalk panels. The average strike of the Baton Rouge fault in the area to the south is approximately N 79 degrees W, making the angle between the fracture and the fault approximately 29 ... More →

On 18 September 2013, the Ministers in charge of water resources in the four States of the Nubian Sandstone Aquifer System (NSAS) (Chad, Egypt, Libya & Sudan), and the Chair of the Joint Authority for the Study and Development of the Nubian Aquifer, signed an important document, the Regional Strategic Action Plan (SAP). The NSAS is one of the largest aquifer systems in the world, composed of non-renewable groundwater. It extends over 2,000,000 km2 and contains about 540,000 km3 of water, out of which 15,340 km3 is believed to be exploitable. Cooperation over the NSAS dates back at least to... More →

This thesis analyzes the progression of average water use, water revenue, and the average cost of water supply for a moderately-sized municipality, the City of Santa Barbara, California, during an extreme drought event from 1987 to 1992.

The 1987- 1992 drought was one of the most severe to strike the State of California this century. The study area was struck particularly hard. Prior to the drought, the City of Santa Barbara was solely dependent on local water sources to supply its water users. This made it particularly vulnerable to the recurrent droughts which are part of the reg... More →

The Upper Coastal Plains region of Texas is located directly to the north and west of the Gulf Coast region of the state. The region stretches northeast from Texas, border with Mexico, extending into Arkansas and Louisiana. The Carrizo-Wilcox Aquifer, one of the state major aquifers, is the principal aquifer and the primary source of groundwater throughout the region. In addition, the Queen City, Sparta, Yegua-Jackson, and Brazos River Alluvium aquifers are important sources of ground water for this region.

Uses of ground water vary throughout the region, with irrigation in the fer... More →

Arsenic (As)is a metalloid element (atomic number 33) with one naturally occurring isotope of atomic mass 75, and four oxidation states (-3, 0, +3, and +5). In the aqueous environment, the +3 and +5 oxidation states are most prevalent, as the oxyanions arsenite (H3AsO3 or H2AsO3 - at pH ~9-11) and arsenate (H2AsO4 - and HAsO4 2 - at pH ~4-10). In soils, arsine gases (containing As3-) may be generated by fungi and other organisms.
The different forms of As have different toxicities, with arsine gas being the most toxic form. Of the inorganic oxyanions, arsenite is considered more toxic tha... More →

According to Jeff Falk of Rice University, research brief from the Baker Institute for Public Policy concluded that an understanding and utilization of unconventional water resources can serve to increase water security and assist economic growth, effectively closing the gap between water supply and demand. One unconventional water source is brackish groundwater (water with high TDS between 1,000 and 10,000 ppm). For example, in Texas, oil and gas producers are using brackish groundwater as an alternative source of water for hydraulic fracking operations, especially in the Eagle Ford, Permian,... More →
