BLOCK 9: ENVIRONMENTAL HEALTH - Unit 13: Water Surveys (complete) Flashcards
An on-site review of a public water system’s water source, facilities, equipment, operation, and maintenance.
SANITARY SURVEY
What are the 8 areas evaluated during a sanitary survey?
- water sources
- treatment
- distribution systems
- finished water storage
- pumps, pump facilities and controls
- monitoring, reporting and data verification
- water system management and operations
- and operator compliance with State requirements
What is the purpose of performing a sanitary survey?
TO COMPLY WITH REGULATORY REQUIREMENTS
It also determines if the system has the capability to produce and distribute an adequate supply of water to meet the peak demand for water, ensures the treated water quality meets all drinking water standards, and identifies deficiencies so they can be corrected.
A sanitary survey for a non-community water system should be performed every _____ years.
EVERY 5 YEARS
A detailed review of the water system’s file to prepare for the survey which pays particular attention to past sanitary survey reports and previously identified problems and their solutions.
PRE SURVEY
Involves interviewing those in charge of the system, as well as the operators and technical personnel.
ON SITE SURVEY
Each sanitary survey should be documented by having the inspector prepare a final written _______________ report of the findings.
POST SURVEY REPORT
___________________ personnel, with the assistance of BE personnel, and/or qualified contractors, are required to survey all facilities and water-using equipment and systems at least every five years.
CIVIL ENGINEERING (CE)
All backflow prevention/cross-connection surveys are accomplished under the supervision of the base ____________________.
BACKFLOW PROGRAM MANAGER (BPM)
Is depicted as “contamination.” In this sense, a contaminant is a substance that will cause an impairment of the quality of the potable water that creates a serious or actual health hazard to public health through poisoning or through the spread of disease by sewage, industrial fluids, chemicals, or wastewaters.
HIGH HAZARD
Is depicted as “pollution”, referring to a pollutant that enters a public water system (PWS). The pollutant will degrade the quality or usefulness of water not creating an actual hazard to the public health; but does adversely and unreasonably affect the domestic use of that water.
LOW HAZARD
BE will sample aircraft watering points _______________ for bacteriological analysis.
MONTHLY
Evaluates the ability of the installation to prevent contamination and service disruptions, as well as the ability to mitigate or moderate the effects and quickly return the system to normal operations when these contingencies are unavoidable. Vulnerabilities are identified, solutions are proposed, and a risk assessment process is used to assist decision-makers in prioritizing corrective actions and allocating limited resources to best protect people and critical assets.
WATER VULNERABILITY ASSESSMENTS (WVA)
What WVA phase is identified by these actions:
- Perform site surveys
- Determine critical control points (CCPs)
PHASE 2
What WVA phase is identifies by these actions:
- Plan, organize, coordinate, and review available data
- Interview subject matter experts (SMEs)
- Collect and review data elements
PHASE 1
