3 Bureau of Water Supply Protection - Overview

4 Bureau of Water Supply Protection (BWSP) Mission To protect the health, safety and welfare of the residents and visitors of New York State through regulatory oversight and implementation, technical support, and response activities for: 1) public water systems (about 9,100) 2) bulk and bottled water facilities (70 bulk haulers, 151 bottlers) 3) private/non-public water supplies (about 800,000) 4) on-site waste treatment systems 5) realty subdivisions 6) recreational water (i.e. engineering plan review of pools and spray parks) 7) nursing home and hospital potable water for protection against Legionella (over 800) 8) cooling tower registration and proper operation for protection against Legionella (over 10,000) 9) emerging water supply issues, including unregulated contaminants

5 Bureau of Water Supply Protection (BWSP) Regulatory Responsibilities (under 10 NYCRR)  New York State's Public Drinking Water Supplies - Subpart 5-1 (municipal water supplies, schools, businesses, etc.)  Certification of Drinking Water Treatment Operators - 10 NYCRR Subpart 5-4  Certification of Bottled and Bulk Water Supplies - Subpart 5-6  Private/Non-public Wells and On-site Waste Treatment System - Appendix 5-B, Part 75, Appendix 75-A & 75C:  Realty Subdivisions - Part 74  Recreational Waters - Part 6 (engineering review of pools, spray parks, etc.)  Cooling Towers – Subpart 4-1 (Protection Against Legionella)  Health Care Facilities - Subpart 4-2 (Protection Against Legionella)

6 Bureau of Water Supply Protection (BWSP) Organization and Staffing BWSP is comprised of about 50 staff including engineers, scientists, data managers, public health specialists, mapping specialists, and administrative professionals. Special Projects Director Assistant Directors Administration Compliance Water Systems New York Residential and Professional Control City Operations Design Sanitation Certification Information and Watershed Systems Analysis BWSP staff implement programs through the regional and field structure in collaboration with local, state and federal partners/stakeholders .

7 NYSDOH – Regional & Field Structure The water supply program is implemented and overseen through a regional structure Core roles and services provided by: 37 - Full service City & County Health Departments 9 - State District Offices Local Health Departments (LHDs)

8 NYSDOH – Field Structure Field Coordinators • Liaisons between the State and County DOH County DOH • Daily regulatory oversight of water systems • Update SDWIS – input data, violations, etc.

10 Where Does Your Drinking Water Come From?

11 Facts & Figures 9,100 public water systems (PWSs) 8,130 PWSs use groundwater (serving pop. ≈ 5 Million) 960 PWSs use surface water supplies (serving pop. ≈ 16.4 Million) More than 7,600 freshwater lakes, ponds and reservoirs that are used for recreation and water supply.

12 Threats to Drinking Water

13 Threats to Drinking Water Pathogenic Organisms Bacteria Typhoid - salmonella typhi Cholera - vibrio cholera E. coli 0157 Viruses Human enteric viruses hepatitis A & polio Protozoans & Parasites Giardia & cryptosporidium

14 Threats to Drinking Water Chemicals Naturally Occurring Chemicals Arsenic, radionuclides, metals ... Biologicals (algae, decomposition) Industrial Chemicals Metals - Pb, Hg, Se ... Organics - benzene, MTBE, TCE, PCBs... Agricultural Chemicals Pesticides, fertilizers ... Emerging Contaminants 1,4-Dioxane, PFAS, Harmful Algal Blooms (HABs)

15 Threats to Drinking Water Quality & Aesthetics Turbidity Suspended Solids Taste, Odor and Color agents Quantity Drought Source Characteristics Use and Replenishment Leaks and Breaks

16 Threats to Drinking Water Mitigation Through Multi-Barrier Protection  Regulation  Source Protection  Treatment (Filtration, Disinfection....)  Design, construction, and maintenance of infrastructure  Operator certification and training  Monitoring  Inspection / Sanitary Survey

17 Public Water Systems

18 Public Water Systems What is a Public Water System? A water system which provides piped water to the public for human consumption, if such system has at least five service connections or regularly serves an average of at least 25 individuals daily at least 60 days out of the year > 9,000 PWS in NY State

19 Public Water Systems Federal vs. Non-Federal Water Systems  Federal PWS - 15 or more service connections or 25 or more people  State PWS - 5 or more service connections or 25 or more people (examples: small mobile home parks and apartment buildings)  Other PWS - PWSs that receive a permit from the health department (i.e., food services, hotels, campgrounds, children’s camps, etc.)

20 Types of Public Water Systems - Community (CWS) – residential A public water system which serves at least five service connections used by year-round residents or regularly serves at least 25 year- round residents - Non-Community (NC) – non-residential - Non-transient non-community (NTNC) Regularly serves at least 25 of the same persons , four hours or more per day, for four or more days per week, for 26 or more weeks per year - Transient non-community (TNC) A noncommunity water system that does not regularly serve at least 25 of the same people over six months per year

21 Types of Public Water Systems Examples: - Community (CWS) – Municipalities, private water companies, apartment complexes, mobile home parks (≈ 2,840 CWS in NYS) - Non-transient non-community (NTNC) – Schools, hospitals, office buildings (≈ 725 NTNCWS in NYS) - Transient non-community (TNC) – Restaurants, Convenience Stores (≈ 5,520 TNCWS in NYS)

22 Regulation of Public Water Systems

23 Regulation of Public Water Systems • EPA role – Sets national standards/regulations – States act as primary regulators • NYS role – Primacy (state must adopt national regs and show EPA how it will carry them out and enforce). – NYS can develop regs in addition to EPA’s • Field Structure – Regions, Counties, District Offices

24 Regulation of Public Water Systems EPA Drinking Water Regulations • • Contaminant Candidates List 1998 Safe Drinking Water Act (SDWA) 1974 • • Unregulated Contaminant Interim Primary Drinking Water Monitoring Requirements 1998 Standards 1977 • Public Notification Rule 2000 • SDWA Amendments 1986 • Radionuclides Rule 2000 • Surface Water Treatment Rule • Long Term 1 Enhanced and (SWTR) 1989 Long Term 2 ESWTR 2002/2006 • Total Coliform Rule 1989 • Arsenic Rule 2002 • Information Collection Rule 1990 • Stage 2 DDBP Rule 2006 • Lead and Copper Rule 1991 • Groundwater Rule 2006 Disinfection & Disinfection Byproduct (DDBP) /Stage 2 1993/2006 • Revised Total Coliform Rule 2013 • Interim Enhanced SWTR 1996 http://water.epa.gov/lawsregs/rulesregs/sdwa/currentregulations.cfm

25 Regulation of Public Water Systems How Does NYS Regulate Drinking Water Systems?

26 Regulation of Public Water Systems Part 5 Appendices  Recommended Standards for Water Works, a.k.a.10 States Standards (Appendix 5-A)  Standards for Water Wells (Appendix 5-B and 5-D)  Operator Certification (Subpart 5-4) (standards for drinking water infrastructure design and construction that are incorporated into the code)

27 Approval of Plans for Public Water Systems

28 Approval of Plans for Public Water Systems NYS Sanitary Code – Section 5-1.22(a): No supplier of water shall make, install or construct, or allow to be made, installed or constructed, a public water system or any addition or deletion to or modification of a public water system until the plans and specifications have been submitted to and approved by the State.
