Certification exams administered by the National Ground Water Association in June, with 8 of those passing. Also administered were 43 licensing exams, with 24 passing. Newly certified professionals in June, including three Certified Well Drillers (CWDs), one Certified Vertical Closed Loop Driller, one Certified Pump Installer (CPI), and one CWD/PI. New members NGWA registered in June. The total con- sisted of 43 scientists and engineers, 39 contractors, 12 government/academic professionals, 5 associates, 4 stu- dents, 3 manufacturer representatives, 3 public groundwater systems professionals, 2 manufacturers, and 1 supplier. NGWA's latest BSP—"Reducing Problematic Concentra- tions of Lead in Residential Water Well Systems"—is avail- able on NGWA's website. The Association's 19th best suggested practice has background on health and safety ef- fects, construction methodologies related to minimizing the chance of encountering lead, and treatment options. but fun way that keeps those watching alert to the important details. Suitable to the drilling of both domestic water supply and environmental wells because many of the same haz- ards apply, the video isn't just for new drill crew employ- ees, but also seasoned workers who may need a refresher on safe practices. The video covers the most common causes of drill site accidents: slips, trips, and falls; materials handling; chem- icals; machine guarding; and electrocution. In addition to the video, the DVD includes printable documents—a job safety analysis form, lighting guidelines, pre-trip inspec- tion form, and safety assessment plan. A version produced in Spanish is also available. • Detailed discussions on safety are now easy to conduct with Safety Meetings for the Groundwater Industry. A set of 52 sheets printed on two-part carbon- less paper, the safety sheets are designed to enable com- panies to have weekly safety meetings on a different industry-specific subject each week of the year. Each sheet contains talking points, areas to write down related topics and employee recommendations, and employee and manager signatures. Among the topics covered are heat-related illnesses, eye protection, excavation safety, slips and falls, confined spaces, and safe footwear. Diversify Your Professional Experience, Become a CVCLD NGWA is proud to offer the Certified Vertical Closed Loop Driller designation. Advances in ground source heat pump technology have emphasized the need for a voluntary certification designation for ground source heat pump drillers. This CVCLD designation reflects an individual who has proven knowledge, skills, and experience in the construction of a closed loop well system for ground source heat pump applications. By becoming a CVCLD, you will increase your company's marketability over your competition. Exams for the CVCLD designation can be scheduled by calling PSI Laser Grade at (800) 211-2754. If outside the United States, call (360) 896-9111. The 75 questions on the exam cover the skills and competencies reflected on the Geothermal Vertical Closed Loop Drilling Operations DACUM.

This particular document outlines the best suggested practices for reducing the possibility of lead concentrations in residential water well systems. Because of varying geologic conditions and other factors, it is not practical to develop a totally prescriptive guideline. There are references throughout this document to public health standards in the United States; other nations may have different standards, and standards may change. Sometimes the concentrations of select constituents will prove to be unacceptably high even after careful site selection and well construction, or after cleaning an existing well. The water well system professional (WWSP) can recommend cost-effective water-treatment options to mitigate such problems. For instance, it may be less expensive for the consumer to install an appropriate water-treatment technology to remove or lower concentrations of a contaminant than to replace or deepen an existing well. On the other hand, if a water-intake area in an existing well has to be replaced or an aquifer lined off, economics will probably favor construction of a new well. Such decisions are site-specific and, thus, based on careful analysis by the WWSP. • Section 1 offers background on the health effects from excessive levels of lead and the related regulatory responses. • Section 2 includes information on sources of lead in water systems. • Section 3 provides a description of well location and construction methodologies related to minimizing the presence of lead. Generally, all construction and maintenance practices must comply with local and state requirements. • Section 4 summarizes groundwater analyses and treatment methodologies. 6/15/2016 Reducing Problematic Concentrations of Lead in Residential Water Well Systems NGWA Best Suggested Practice Approved by NGWA Board of Directors: national ground water association CERTIFIED ABILITY EXPERIENCE KNOWLEDGE CVCLD-2016
