NGWA Press announces the publication of Operational Stage of the Well, authored by groundwater experts, Thomas M. Hanna, PG, Michael J. Schnieders, PG, PH-GW and John H. Schnieders, PhD, CPC. It explains various factors of well deterioration and how they impact well operation and maintenance. Through research, field and laboratory work, the authors have developed a method for assessing this information and assigning a value to the well in regard to its health. The information is able to extend the operational lifespan of existing wells, while providing valuable information into the design and operation of new well systems. Member and non-member pricing available.
