Hach's water quality test strips are ideal for performing semi-quantitative spot-checks or field tests. They are manufactured with a unique reagent pad at the tip, using proven chemistries based on standard reference methods. Simply dip a strip into the sample, wait for color to develop, and compare color on the reagent pad to the color chart on the bottle. Test strips are available for a wide selection of parameters, with new strips being added regularly.
Questions & Answers
what are the reagents MTK, TMK, and TMB and how do they differ from DPD?
MTK and TMK both stand for Thio-Michler's ketone (Michler's thioketone) and react with certain metals, including gold, silver, mercury and palladium. This reagent can be used for residual chlorine studies. TMB is tetramethylbenzidine and changes color when it comes into contact with ethyl acetate (turns blue/green) or chlorine (turns yellow). DPD is used to determine chlorine concentration by the vividness of the color produced. Depending on the specific reagent model, it can measure free and total chlorine concentrations from 0.02 -10 mg/L. Manganese can interfere with DPD reagents, but not with TMK/MTK reagents.
Can the Hach Chlorine test strips measure chlorine in PPM?
The free & total chlorine test strips mg/L unless otherwise noted. Note: ppb = µg/L; ppm = mg/L.; gpg = grains per gallon; 1 gpg = 17.1 mg/L or 17.1 ppm.

Monitoring Mariculture in the Gulf of Alaska

The mariculture industry in the Gulf of Alaska has been steadily growing in recent years, guided by ongoing research to help refine farm location and cultivation practices. A subset of aquaculture, mariculture focuses on rearing organisms in the open ocean. In Alaska, finfish farming is illegal, so most farms cultivate kelp, oysters, or a combination of the two. These small, locally operated farms started popping up in the Gulf of Alaska in the early 1990s, when shellfish farming first became legal. Kelp farming did not begin to catch on in the state until 2016. Many of the coastal areas that have grown interested in mariculture are historically commercial fishing communities.

Supplying Seattle’s Drinking Water: Using Data Buoys to Monitor the Cedar River Municipal Watershed

Providing clean, safe, and reliable drinking water for the 1.6 million people in the greater Seattle area is a top priority for Seattle Public Utilities (SPU). With limited water supplies, SPU dedicates considerable resources to maintain its watersheds and mountain reservoirs. About 70 percent of Seattle Water comes from the Cedar River Municipal Watershed , and the other 30 percent comes from the South Fork Tolt River Watershed .

Data-Driven Advocacy on the Lower Deschutes River

Like many freshwater environments, the Deschutes River in Oregon is under pressure from development, pollution, and climate change. Many rivers, streams and lakes in the Deschutes Basin do not meet Oregon water quality standards –where state water quality monitoring assesses levels of bacteria, pH, dissolved oxygen, temperature, and fine sediment. Hannah Camel is the Water Quality Coordinator for the Deschutes River Alliance (DRA), a non-profit organization that focuses on the health of the lower 100 miles of the Deschutes River–the area most affected by human intervention. As a data-driven organization, the DRA has benefited from the installation of two NexSens X2 data loggers.
