4. State and Federal Regulation Currently No Federal Or Pennsylvania State Regulations Related to Private Water Well Construction. Currently No Federal Or Pennsylvania State Regulations Related to Private Water Well Construction. Pennsylvania has over 1 million households on Private Wells. Pennsylvania has over 1 million households on Private Wells.  Pennsylvania one of 4 states that has no private water well construction standards, via regulation.  PA does not really have a comprehensive certification program for drilling contractors and operators.

5. State Regulations (Existing/ Proposed) Pennsylvania Has Drillers Licensing Program http://www.dcnr.state.pa.us/topogeo/groundwater/act610.htm http://www.dcnr.state.pa.us/topogeo/groundwater/act610.htm Act 537: Chapter 73: Minimum Isolation Distance On-lot Septic System and Components and Private Well House Bill 1591 Proposed Legislation: Private Well Construction Regulations http://www.legis.state.pa.us/WU01/LI/BI/BT/2001/0/HB1591P2920.HTM http://www.legis.state.pa.us/WU01/LI/BI/BT/2001/0/HB1591P2920.HTM

11. Too Close to the Road Potential Problems 1) Damaged Casing 2) Chemical Spills 3) Road Salting Agents 4) Chemical Sprays 5) Vandalism

12. Well Cap Not Secure

13. Standard Well CapSanitary Well Cap Allow entry for insects, small animals Sealed to prevent contamination Well Construction Options for Private Wells

14. Poor construction can affect drinking water quality Poor construction can affect drinking water quality Poor construction can contribute, promote, and facilitate pollution and contamination of the groundwater aquifer Poor construction can contribute, promote, and facilitate pollution and contamination of the groundwater aquifer Proper construction can prolong the life and yield of the well Proper construction can prolong the life and yield of the well Why Care About Well Construction ?

15. A Properly Constructed (Sanitary) Residential Water Well Has: casing that extends at least 15 feet into firm bedrock or 40 feet below ground, whichever is greater casing that extends at least 15 feet into firm bedrock or 40 feet below ground, whichever is greater casing of adequate wall thickness (meet PADEP Requirements Community Water Supplies) casing of adequate wall thickness (meet PADEP Requirements Community Water Supplies) a drive shoe on the bottom of the casing a drive shoe on the bottom of the casing

16. Well Construction Open Hole Bedrock Well

17. Standard Well Cap “The Unsanitary Well Cap” Insects, Larvae and Nests / Egg Masses Mouse Colonies Snakes Beehives Mud - when casing to close to ground Types of Contamination - Bacteria, Subject to Vandalism, Salts

28. Why an Ordinance? Primary reasons for the ordinances included: Improper Well Construction Improper Well Construction Incidents of Well Contamination Incidents of Well Contamination  Improper Siting  Interconnection with Contaminated Site  Induce Contamination – Lack of Grouting  No Testing Requirements to ensure potability Overuse of the Groundwater Aquifer. Overuse of the Groundwater Aquifer. Online Directory of State Water Well Ordinances http://www.epa.gov/R5water/ordcom/ http://www.epa.gov/R5water/ordcom/

29. Before You Drill Get a Well Construction Contract Written contract with well driller prior to construction Assurance of compliance with regulations Liability insurance information for driller Casing specifications (6" minimum to bedrock) Sanitary cap, grout seal? Well development to maximize yield Disinfection after drilling and pump installation Timeline for completion Guarantee on materials and workmanship Itemized estimate - check before exceeding costs 8-12 hour pump test (sustained yield) and basic water test Delivery of well log and pump test results to owner
