Drinking Water Surveillance/Monitoring: Drinking water supplies (regardless of whether purchased or produced) must meet the minimum requirements set forth in the country-specific Final Governing Standards (FGS). PHCR-Europe can monitor drinking water systems for most parameters and frequencies cited in the FGS. In addition, should you have a requirement for quarterly monitoring, PHCR-Europe can incorporate that requirement into the annual surveillance program. This ensures that your water systems maintain compliance with the FGS and provides historical information showing trends in water quality over time. For your lead and copper monitoring program (sampling at the tap), we can accomplish the task of sample container distribution and collection among your tenants, along with transporting samples back to our laboratory for analysis, easing the manpower burden on your staff.

Water System Sanitary Surveys: We conduct a comprehensive on-site inspection of your water sources, facilities, equipment, system management and related plans, and operation and maintenance procedures and activities to determine their adequacy for producing and distributing potable water to your consumers, and to determine compliance with regulatory and operational requirements. Conducting sanitary surveys on a regular basis is the best way to identify potential problems and possible reasons for trends in water quality and demand that may need to be addressed. The surveys provide an impartial look at water systems. Added benefits include operator education, validation/improvement of operations & maintenance practices, and improvements in system compliance to name a few.

Security-Based Water System Vulnerability Assessments: This vulnerability assessment is accomplished in accordance with the latest guidance from the Department of Defense. We will bring a team on site for 7-10 days and assess the hazard vulnerability for all intentional/non-intentional threats to your potable water systems, regardless of supplier/system owner/operator. We will assess risk to the water systems based on the effectiveness of existing and planned measures to counteract adversarial actions, identify corrective actions to eliminate or reduce risk to acceptable levels, and provide managers and commanders the means to prioritize corrective actions and allocate limited resources to best protect the public's health and your mission-critical assets.

Cross Connection and Backflow Prevention Program: We will evaluate various service and point-of-use connections where conditions exist that may result in potable water contamination by wastewater and wastewater connections. We will identify cross-connections and assign appropriate hazard classes; determine proper devices for specific applications and whether those already installed are appropriate; visually inspect, tag, and inventory all testable devices; and establish a database and populate it with site-specific data.

Water System Emergency Response Plans: We will prepare your plan to meet the Department of Defense requirements, establishing specific response actions for water contamination or disruption events while incorporating threat scenarios and the potential hazards identified in the completed security-based Water System Vulnerability Assessment.

Watershed/Wellhead Protection Surveys: Required every 5 years by the Final Governing Standards, this environmental vulnerability assessment determines whether identified contaminants of concern have been used in a watershed area, or if used, evaluates the susceptibility of your drinking water source(s) to contamination. Susceptibility is based on prior occurrence, vulnerability assessment results, environmental persistence and transport of contaminants, and any wellhead protection program results.

Unidirectional Flushing Plans: The Final Governing Standards requires an effective annual water main flushing plan/program. Many installations flush their water distribution systems employing conventional or improper ad-hoc methods, and end up creating water quality problems instead of improving water quality as intended. The industry's best management practice since 1999 is unidirectional flushing. Unidirectional flushing is a significant improvement over the conventional flushing method in that it cleanses the water distribution lines through a network of independent flushing sequences. Utilizing specialized software, we will model your systems, incorporating actual data (demand, flow rates, etc.) to develop the a valve and hydrant manipulation sequence: this procedure will be designed to obtain unidirectional flushing, maximize velocity in the mains for effective scouring, and minimize the amount of work required by those personnel charged with implementing the plan on the system. Additionally, approximately 40% less water is used compared to conventional system flushing. This procedure is effective as either a regular operations and maintenance practice or a mitigating procedure for contamination of the water system; a key component for emergency response to potential accidental or willful contamination of the potable water system.

Water System Corrosion Control Studies: We study various water quality parameters over time to determine the corrosivity of your water and recommend options for corrosion control in order to improve water quality and extend the life of water distribution system components.

Plumbing Profiles: Did your lead and copper monitoring at the tap reveal an exceedance? We will find those potential sources of lead and/or copper leaching into your water distribution or a facility's plumbing system, and recommend appropriate methods to remedy the problem.
