Runoff samples needed from houses in Port Townsend, Wash., with roofs made with composite material

A storm water runoff study is being sought by the Port Townsend Marine Science Center. The center is working alongside University of Washington Center for Urban Waters (UW) scientists who want to study the toxic chemicals that run from roofs.

Center personnel have been seeking roofs from houses that have been built or otherwise reroofed with composite roofing material. The houses should have been roofed in the last three years and ought possess metal rain gutters to keep the study consistent.

Emerging Chemical Concerns

Many adverse ecological effects have been attributed to pharmaceutical and personal care products (PPCPs) and endocrine-disrupting compounds (EDCs), but it is not clear what risk they pose to human health. In the past, water was known to contain these chemicals, but the exact amount was difficult to quantify. Recently, these chemicals have gained much more attention.

The new D14–14 GPM series of chemical injectors are powered by water flow, reducing energy costs. They accurately and continuously inject chemicals at the point of application. Variations in water flow or pressure do not affect operation, offering consistent, repeatable results. Their precise ratio adjuster allows for minute adjustments, enabling the user to control chemical costs.

Activated Carbon

Activated carbon is an excellent adsorbent due to its large surface area and the fact that the diverse surfaces can take on many different types of contaminants.

Preserving Pipelines

Well-maintained and functional sewer systems are a major asset in any community, but they require regular cleaning, inspection and maintenance. Chemical grouting too often is viewed as a stopgap measure to reduce groundwater infiltration. In reality, grouting does much more to maintain sewer line integrity. It also is a soil-sealing process that stabilizes the sewer bedding soil, preventing washout of bedding fines and resulting pipe misalignment and joint failure.
