The quality of drinking water from wells may be compromised during a flood. Flooding around the well increases the risk of drinking water becoming contaminated with bacteria or any other contaminants, rendering it unsafe to drink and for washing food items. This publication describes the steps to take when you suspect that your well has been affected by flooding. Steps include well inspection, calculation of the depth of water and storage capacity of the well, shock chlorination, and laboratory bacteria testing. The circular also discusses tips on how to know whether the water is safe to drink again.

Cation exchange capacity (CEC) is a measure of the total negative charges within the soil that adsorb plant nutrient cations such as calcium (Ca2+), magnesium (Mg2+) and potassium (K+). As such, the CEC is a property of a soil that describes its capacity to supply nutrient cations to the soil solution for plant uptake.

A regular fertilization program is important to maintain healthy, attractive turf and should include applying the correct analysis of fertilizer, using the correct amount, and fertilizing at the proper time. Turfgrasses require a number of nutrients for growth. Three of these—carbon, hydrogen, and oxygen—are rarely lacking because grasses get these elements from carbon dioxide in the atmosphere and water from the soil. Understanding fertilizer terminology and the different types of nitrogen sources is important when establishing a lawn management plant. Nontraditional or “organic” fertilizers are also an option.
