What is one of the key components of a site sampling plan?

A site sampling plan is essential for ensuring that water quality is maintained and meets regulatory standards. A key component of this plan involves collecting samples that can provide insights into potential contaminants in the water supply. Disinfection by-products (DBPs) are a significant concern in water treatment processes, particularly where chlorine and other disinfectants are used. These compounds can pose health risks if they exceed certain levels.

Including samples for disinfection by-products in the sampling plan ensures that the water is routinely tested for these potentially harmful chemicals, allowing for proactive management and remediation strategies if necessary. This component is crucial for protecting public health and ensuring compliance with environmental regulations.

In contrast, focusing solely on lead and copper or only on microbiological samples would provide an incomplete picture of the water quality, as these do not encompass all categories of potential contaminants that might be present. Therefore, considering disinfection by-products as part of a comprehensive monitoring strategy is essential for effective water quality management.
