RFP-BM-Larkspur-Pilot Study - Larkspur Pilot Study Services

Summary of Specifications:
The Town of Larkspur has recently completed the drilling of a new water supply well into the Arapahoe Aquifer to serve potable water to the Town. Water quality testing has shown levels of radium (226 & 228) that are above the primary drinking water standard. In addition, there is iron and manganese in concentrations that exceed the secondary drinking water standards. The Town must develop an approach to either 1 - remove the radium in soluble form so that the soluble form of radium can be disposed of in the sanitary sewer or retain the radium by using an ion exchange media with media disposal on a periodic basis or 2 - re-solubilize the radium associated with particulates in the washwater by adjusting the PH of the washwater. The goals of the pilot study services are to demonstrate the removal of radium, iron, and manganese by addressing the approaches above with the result of providing the specific treatment process approach and design criteria for full scale treatment.
