ST. MARY’S COUNTY METROPOLITAN COMMISSION PUBLIC HEARING FOR THE PROPOSED PROJECT TO ADDRESS ARSENIC LEVELS IN PUBLIC WATER SYSTEMS
ST. MARY’S COUNTY METROPOLITAN COMMISSION The EPA has determined that all public water supplies must meet the new 10 ppb (old 50 ppb) limit for Arsenic by January 23, 2006.
ST. MARY’S COUNTY METROPOLITAN COMMISSION It is important to note that the LIMIT is changing not the WATER QUALITY.
Arsenic OccurrenceWhere does it come from? ST. MARY’S COUNTY METROPOLITAN COMMISSION
ST. MARY’S COUNTY METROPOLITAN COMMISSION • Naturally occurring element • Found throughout the United States • Weathers from rocks and soils
ST. MARY’S COUNTY METROPOLITAN COMMISSION • Primarily found in ground waters • Also associated with wood preserving, mining, agriculture, pulp and paper production, burning of fossil fuels
ST. MARY’S COUNTY METROPOLITAN COMMISSION In St. Mary’s County certain areas of the Piney Point & Aquia Aquifers have Arsenic Levels of 10-20 ppb. The source is believed to be from ancient marine sediment.
ST. MARY’S COUNTY METROPOLITAN COMMISSION Compliance Alternatives Treatment to remove Arsenic Mixing with Arsenic Free water Find New Arsenic Free source
ST. MARY’S COUNTY METROPOLITAN COMMISSION MetCom decided in 2000 that the least expensive solution was to abandon the water sources that exceeded the proposed limit and replace the supply with water that was Arsenic free.
ST. MARY’S COUNTY METROPOLITAN COMMISSION Maryland Geological Survey (MGS) was studying the Patapsco aquifer to see if it could meet the needs of Southern Maryland.
ST. MARY’S COUNTY METROPOLITAN COMMISSION Test wells drilled by MGS determined that areas where the Aquia aquifer had elevated levels of Arsenic, the Patapsco did not have any Arsenic.
ST. MARY’S COUNTY METROPOLITAN COMMISSION MetCom was hesitant to commit until the study was completed. Completion was scheduled for 2003 but the project was delayed until July 0f 2005.
ST. MARY’S COUNTY METROPOLITAN COMMISSION The Metropolitan Commission will not meet the January 23, 2006 deadline for compliance with the Arsenic Rule
ST. MARY’S COUNTY METROPOLITAN COMMISSION MetCom has requested 1 year extensions for Breton Bay, Mulberry South, St. Mary’s Industrial Park and Holland Forrest systems to drill new wells.
ST. MARY’S COUNTY METROPOLITAN COMMISSION MetCom has requested 2 year extensions for Hollywood and Fenwick Manor to extend water service from another supply.
Systems Are Eligible for an Exemption If They Can’t Comply by January 23, 2006:
Due to “compelling factors” • Exemption will not result in an unreasonable risk to health
System is unable to make management and/or restructuring changes • System began operating by February 22, 2002
ST. MARY’S COUNTY METROPOLITAN COMMISSION Exemptions Are Not a Way to Avoid Compliance
Potential tool to help States address systems with greatest challenges • Systems are put on a schedule to compliance by end of exemption period
Public information is required Consumer Confidence Report (CCR) Public Hearings
