Chemists for Clean Water

At reservoirs in Bangladesh, chemists arehard at work purifying local water

supplies. These experts use filters toremove arsenic from the reservoirs,

creating a potable water supply for nearbyresidents. Many of these experts are

affiliated with 1 ChemistsWithout Borders (CWB). CWB is an organization that

provides assistancefor crucial human health issues such as clean water.

Operating not only in Bangladeshbut also in the United States and other nations,

CWB relies on the efforts oftrained, professional chemists, as well as those of

2 volunteers’ interestedin entering the field.

Professional chemists at CWB seek outprojects that can provide help directly

to populations in need. Their workin 3 Bangladeshinvolves removing toxins, from

the drinking water, primarily throughwater purification. CWB staff members

create and give arsenic testing kits toBangladeshi locals and work with

interpreters to 4 dissipate informationand instructions. 5 CWB also provides

education about medicine,vaccines, and environmental sustainability.

6 CWB also works with volunteers who arerigorously trained chemists. While

some volunteers are concernedcitizens who want to assist with public education 7

campaigns. Others hold actualchemistry training. The education background for

water chemists is varied butincludes many disciplines, including microbiology

and geology. Students explorethese related fields to develop a more

comprehensive view of the variables thataffect water quality. 8 They might

study, for example, the microorganismsliving in water, or the effects of

particular rocks and soil on water supplies. Volunteerswith a rich background in

chemistry also help the CWB professionals with watertesting and supply kit

creation. This practical experience is an excellentopportunity for prospective

water chemists to gain insights into what the jobentails.

9 A career in water chemistry leading toexciting travel and teaching

opportunities, and working to de-contaminate watersupplies around the world is a

rewarding experience for those who undertake it.Also worth noting is the fact

that demand for skilled water chemists 10 are onthe rise. According to the US

Bureau of Labor Statistics, the number of jobs inthis field is expected to grow

8 percent by 2022. 11 Looking beyond that, theneed for water chemists will

likely continue to grow to meet the increasingwater demands of our burgeoning

global population.

5 At this point, the writer wants toelaborate on the information in the

preceding sentence by providing additional,relevant details. Which choice best

accomplishes this goal?

These kits include a hand-helddevice that allows users to identify arsenic

concentrations in the water;arsenic is then removed using a filtration

system.

Arsenic is a metalloid that isoften used for strengthening metal alloys that

include copper and lead.

Another important area ofeducation is vaccines; people living in Bangladesh

have access to vaccines butoften do not receive them.

Some of the CWB representativesare fluent in Bengali, the official language

of Bangladesh.

writer make this deletion?

Yes, because it blurs theparagraph’s focus on the education of water

chemists.

Yes, because it is redundantwith information provided earlier in the

passage.

No, because it providesinformation that supports a claim made in the

introductory paragraph.

No, because it providesexamples that elaborate on the previous sentence.

The need for water chemistswill likely continue to grow as individuals take

advantage of the travelopportunities that this field provides.
