Year round, concentrations of base cations (Ca, Mg, Na, and K) and Cl − in surface and groundwater decline exponentially away from Interstate 95, a four-lane asphalt highway which bisects Alton Bog, a poor fen in Penobscot County, Maine, USA. The i

High Radon-222 (222Rn) concentrations exist in ground water from most granitic rocks in Maine. Some values exceed the suggested limit of 500 pCi/1 (E.P.A., 1976) by more than 100 times. Although high values (x= 22,100 pCi/1) are conclusively linked w

Confined aquifers may develop water table conditions near the well bore and under prolonged pumping stresses this condition may spread to the recharge area. This situation is defined as the transition problem. The physics of the transition problem is

The applicability of the Monte Carlo simulation technique to water quality modeling is demonstrated with the aid of a simple Streeter-Phelps model. The model accounts for the stochasticity of the input parameters. Triangular probability density funct

This study is part of an interdisciplinary analysis of the economic evaluation of the water resources of the Rio Grande region of New Mexico. It was elemental in obtaining dynamic water availabilities in time and space. The relationship of dynamic gr

Marine clays of Maine may be more resistant to physico-chemical alteration when permeated with solvents than are other more mineral-rich clays used in previous studies. This conclusion is preliminary. Long duration permeameter testing and chemical an

Two processes were investigated in the laboratory to determine their efficiency for removing radon from household water supplies. Granular activated carbon (GAC) adsorption was found to be extremely effective as a result of an adsorption-decay steady

In the solution of nonlinear parabolic partial differential equations, such as the Richards equation, classical implicit schemes often oscillate and fail to converge. A fully implicit scheme has been developed along with a functional iteration method

The unsteady spatially varied flow equations (De Saint-Venant equations) are being solved by implicit finite differences with explicit description at the boundaries. Imposition of improper boundary conditions which violate the physics of the problem
