Lead In Your Drinking Water, Joseph L. Taraba

Agricultural Engineering Extension Updates

The U.S. Environmental Protection Agency (USEPA) recently imposed a regulation requiring public water suppliers to notify all their customers of the potential health effects of lead from household plumbing. The USEPA regulates public water supplies (with at least 15 service connections or servicing 25 individuals) but does not regulate private water supplies. The potential health hazard of lead is also present from household plumbing which is supplied water from a private water source.

Bottled Water, Joseph L. Taraba

Agricultural Engineering Extension Updates

Bottled water is an option for families who have a water problem, whether their water is unsafe or has an "off" taste or odor. It is best used as a temporary measure or in small quantities for drinking water. At a cost of 65 cents to $1.15 per gallon (Lexington, KY; July 1988) bottled water could become an expensive item for a large family using it for drinking and cooking.

An Aeration Duct Design Model For Flat Grain Storage, Thomas C. Bridges, Douglas G. Overhults, Samuel G. Mcneill, G. M. White

Biosystems and Agricultural Engineering Faculty Publications

Traditionally most grain is stored in circular type bins which provide a convenient means for handling and management. With the excess grain production and government loan programs of the past few years, some producers have used rectangular structures and covered piles to complement their round storages. The recommended management practices used with round bins are still required in those alternative storages and may be more critical in obtaining a quality end product.

One such recommended practice used with round bins is aeration. This practice is used to maintain a uniform temperature in the grain mass, preventing condensation and "hot" spots …

Rapid Method For Determining Fertilizer Nutrients In Liquid Dairy And Swine Manures, Joseph L. Taraba

Agricultural Engineering Extension Updates

A rapid on-farm determination is needed to assess the fertilizer contents of liquid manure as it is taken from storage. Rapid determination of a tank load for liquid manure will indicate nutrient changes that occur as manure is removed from a storage which cannot be or is not effectively agitated before manure removal. Effective utilization of animal manures as a fertilizer resource requires a farmer to have a knowledge of the amount of nutrients that he is putting onto the soil. If the producer then reduces the commercial fertilizer, he can realize the fertilizer economic value of the manure. Laboratory …

Vegetable Oil As An Emergency Fuel, E. Holmes, Joseph L. Taraba, George M. Turner

Agricultural Engineering Energy Series

The unstable world political situation combined with the fact that a large amount of the world's oil reserves is located in the Middle East means we must continue to search for an alternate fuel source for our agricultural machinery. It is well-known that there is a limited amount of fossil fuels and even with no world political problems the demand will exceed supply in the not-too-distant future. The United States currently imports fossil fuels because we use more than we produce. Vegetable oils are a renewable resource. They offer a means of keeping our agricultural equipment operating in an oil …

Home Water Testing, Joseph L. Taraba, Tom Ilvento, Linda Heaton, Bob Herbst, Grant Thomas, Dwight Crum

Agricultural Engineering Extension Updates

Routine testing for a few of the most common contaminants is highly recommended. Even if you currently have a safe, pure water supply, regular testing can be valuable because it establishes a record of water quality. This record can be helpful in solving any future problems and in obtaining compensation if someone damages your water supply. Testing needs to be performed by certified testing laboratory using USEPA methods of collection, storage and testing. Unbiased testing needs to be established and has more validity in court proceedings to establish responsibility.
