A fluid flow device for determining fluid flow rates in soils includes a conduit for receiving a fluid. The conduit has a reduced channel portion to form a reduced channel portion which amplifies the fluid flow rate of the fluid. A sensor device is coupled in sensing relation relative to the conduit and configured for measuring the amplified fluid flow rate as the fluid flows through the reduced channel portion.

Fluid flow measuring devices and methods for determining fluid flow rates in soils

The present invention is a method of preventing water from leaching solid waste sites by preventing atmospheric precipitation from contacting waste as the water flows through a solid waste site. The method comprises placing at least one drain hole through the solid waste site. The drain hole is seated to prevent waste material from entering the drain hole, and the solid waste site cover material is layered and graded to direct water to flow toward the drain hole and to soil beneath the waste site.

The present invention relates to improvements in tensiometers for measuring soil water tension comprising a rod shaped wick. the rod shaped wick is shoestring, rolled paper towel, rolled glass microfiber filter, or solid ceramic. The rod shaped wick is secured to the tensiometer by a cone washer and a threaded fitting.

Oil is detected in the presence of water by placing a translucent, porous body of hydrophobic material in contact with the oil and water and detecting the amount by which light incident on the body is attenuated on propagation through the body.
