  • GRACast Web Seminar - Water Well Rehabilitation: Reviewing the Process and Evaluating Methods Utilized
    include the necessary testing before during and after treatment as well as how this information guides the choices use and disposal of the chemicals used The second half of the webinar will examine the chemicals used in well rehabilitation development and disinfection Traditionally chlorine and acid have been the products of choice when combating fouled well systems In addition to these chemicals acid enhancers biodispersants chlorine enhancers surfactants chelating agents emulsifiers and inhibitors are being used in cleaning procedures Understanding what role each of these plays in each step is important Misapplication can result in damage to the well and environment as well as pose a health and safety challenge to those working around the well This section is designed to explain the differences in each of the chemicals where they are applied and common uses variations A very limited overview of preventative monitoring and maintenance following treatment will also be presented Register Today Early Registration by April 8 is 75 for Members and 100 for Non Members Registration after April 8 is 100 for Members and 125 for Non Members SPEAKER BIO Mike Schnieders is the principle hydrogeologist and President of Water Systems Engineering Inc in Ottawa Kansas Mike s primary work involves well characterization and consulting on the operation and maintenance of potable water systems Mike s work crosses numerous disciplines and fields involving geology chemistry microbiology water resource and watershed management corrosion control and water treatment Mike has served on numerous state regional and national training programs focusing on rehabilitation and maintenance of water wells and groundwater systems In addition to authoring numerous articles on well maintenance well field analysis and well construction Mike is the co author of the forthcoming book Operational Stages of the Well Evaluating the Forms of Water Well Deterioration and Developing Corrective
