Well Water Supply and Treatment System – Clark-Shawnee Local School District (CSLSD) – Springfield, Ohio
STONE was retained to prepare the permit application for a Non-transient Non-community (NTNC) water treatment system for a former school building. The building was served by an existing water supply well and an on-site treatment facility, but the Ohio EPA Division of Drinking and Ground Waters had no records for a Well Site Application or Plan Approval for this system.
STONE calculated the average daily water demand for the site and arranged a 10-hour pumping test to determine the well supply capacity. Based on the results of the pump test, STONE determined an appropriate well pump, flow meter, and pressure tank for the site.
A groundwater sample was collected and analyzed for inorganic chemicals, volatile organic chemicals, and bacteria. Analytical results revealed levels of various metals above the Ohio EPA’s drinking water standard that required treatment. STONE designed a chlorine oxidation system to address the metals and a softening system on the end of the proposed chlorine injection and greensand filter system to address water hardness.
