MWRA Boil-Water Order

admin — Mon, 03 May 2010 01:51:48 +0000

As you’ve likely heard, a massive water main break has resulted in communities east of Weston having to boil any water that will be ingested. That includes many of our customers in the Boston area. If you need assistance, Practical Applications can help determine if you can use your water, provide you with bacteriological testing as needed, and help with high purity water system flushes and filter changes once the order has been lifted.

Testing inquiries can be directed to compliance@pai-online.com.

O&M requests should be sent to sbertrand@pai-online.com.

Is There Mercury In Your Industrial Wastewater Discharge?

Is There Mercury In Your Industrial Wastewater Discharge?

This article was written by Practical Applications’ biologist Kimberly Baxter and originally appeared in the December 2005 issue of Plumbing Engineer magazine. A PDF of the article is available HERE.

Abstract

An assessment of sampling locations for three industrial wastewater effluent piping systems is presented. The assessments provided demonstrate that by installing sampling ports at the appropriate location along an effluent stream’s piping system, truly representative samples can be collected. These real and accurate results scientifically prove that a specific industrial wastewater discharge does not contain mercury levels that will trigger regulatory enforcement action.

MA DEP Mercury Regulations

Practical Applications — Tue, 25 Aug 2009 21:52:49 +0000

Name & Citation of Regulation(s)

Collection, Recycling, Labeling and Sales Ban of Mercury-added Products; and Disposal Prohibition of Mercury-added Products in Solid Waste–310 CMR 19.00 (amended), 74.00 (amended), 75.00 (amended), 76.00 (added).

Brief Explanation and Rationale for Changes

Signed into law in July 2006, the “Massachusetts Mercury Management Act” is designed to keep mercury out of our trash and wastewater, where it is released into the environment. MassDEP is implementing this law in two phases. The Phase 1 regulations (promulgated on December 28, 2007) banned the sale of mercury-added products in Massachusetts unless the manufacturer registers the product with an interstate clearinghouse and establishes a collection program for the end-of-life products, banned schools from buying mercury-containing products, required auto manufacturers to collect and recycle mercury switches from “end of life” vehicles, required manufacturers of mercury containing lamps to educate consumers about mercury hazards and the requirement to recycle discarded lamps and to report on lamp recycling to MassDEP.

The Phase 2 regulations (promulgated on August 21, 2009) ban the sale in Massachusetts of specific mercury-added products, establish a procedure for manufacturers to apply for an exemption from the sales ban, and establish labeling requirements for mercury-added products that are sold in Massachusetts. The regulations also prohibit disposal of any mercury-added product in solid waste.
