QUALITY ASSURANCE
The goal of the Greater Lawrence Sanitary District (GLSD) Laboratory is to generate the most precise, accurate and reproducible data possible in a timely and cost-efficient manner. The reliability and integrity of the sampling and analysis reflects directly on an excellent Quality Assurance/Quality Control (QA/QC) Program.


	In any given day, water at the Greater Lawrence Sanitary District starts out as filled with impurities, as shown in the first jar in the photograph above. After filtration and sanitation, the water is purified to a pollutant-free state, and then returned to the Merrimack River.

GLSD recognizes the need to provide data that is representative of the conditions in question and is suitable for making decisions that involve compliance with environmental standards, public health, safety and legal obligations.

, in which GLSD details its comprehensive program of QA/QC.

ONGOING PROGRAMS
All analyses are conducted in strict accordance with approved, up-to-date methodologies and performed by highly trained, skilled technicians. GLSD recognizes that the establishment of a QA/QC program represents a considerable investment of both personnel and capital. GLSD feels this is a worthy investment as it officially documents the continual monitoring of the quality of generated data.

GOVERNMENT REGULATIONS
In addition, government regulatory agencies have specific requirements pertaining to laboratory QA/QC to insure the data they receive is an adequate and fair assessment of environmental conditions present. GLSD maintains its QA/QC program in accordance with guidelines set forth by E.P.A., NELAC and state certification authorities.
