Fall is Ideal for Soil Amendment
By Sarah Browning, UNL Extension Horticulture Educator
Soil amendments can help with many common landscape problems by improving soil's water-holding capacity, increasing soil drainage, increasing nutrient levels and modifying pH level. A soil amendment is any material mixed into the soil to change one of these characteristics- compared to mulch that is applied on top of the soil. Mulches are used to moderate the soil temperature, prevent weed growth and reduce soil moisture evaporation.Continued...
Lead in Drinking Water Part I: Sources, Health Effects, and Testing
By Sharon Skipton, UNL Extension Water Quality Educator
Lead rarely occurs naturally in drinking water. Most lead contamination takes place at some point in the water delivery system. This occurs as a result of corrosion, the reaction between the drinking water and lead that was used in the water delivery system.
The characteristics of water vary greatly depending on the source of the water. Some water is naturally more corrosive. Several factors cause water to be corrosive, including low pH (pH less than 8.0), high temperature, low total dissolved solids (TDS) content, and high amounts of dissolved oxygen or carbon dioxide. Generally, naturally soft water is more corrosive than hard water because it is more acidic and has low TDS. Treating naturally hard water with an ion exchange water softening unit, reverse osmosis unit, or distillation unit may change the water chemistry enough to have an effect on the water's ability to dissolve lead.
Lead in drinking water from plumbing or a fixture is most often a problem in either very old or very new homes and buildings. However, any home or building may be susceptible.
Through the early 1900s it was common to use lead pipes for interior plumbing. Lead piping is most likely found in homes built before 1930. Copper piping replaced lead piping, but lead-based solder was used to join copper piping. Lead-based solder probably was used in any home built before 1988. The U.S. Environmental Protection Agency (EPA) published a public drinking water rule in 1991 that emphasized eliminating lead from components of the water delivery system.
This publication provides information on the value of trees; how to choose the best tree species for various parts of the landscape; and how to properly install and care for them in a water-conserving and drought-conscious manner.
