D.T.H. has a full range of sampling and testing services for Potable, Municipal Sewage, Industrial Wastewater, Surface and Ground water testing solutions as per I.S., A.P.H.A. and B.I.S. specifications.

When toxic substances enter lakes, streams, rivers, oceans, and other water bodies, they get dissolved or lie suspended in water or get deposited on the bed. This results in the pollution of water whereby the quality of the water deteriorates, affecting aquatic ecosystems. Pollutants can also seep down and affect the groundwater deposits.

Stack is the major point source of air pollution. It includes large process stacks, Boiler stacks, Industrial stacks and Generator stacks. As it disperse the potential pollutants to the atmosphere on the basis of dilution but transboundry treaties compel the users to control the emission up to a certain level.

D.T.H. has the all the facility and experience for stack monitoring and analysis including portable toxic gas analyzers and stack kits

DTH has been doing indoor air monitoring and analysis for last three years and serving the clients in embassies, call centers, hospitals and pharma manufacturing industries. We are equipped with most modern instruments like the latest indoor air samplers and also the laser based air particle counter. We can offer complete clean room validation studies with this one CFM particle counter.

When most people think of air pollution, they think about ambient or outdoor air pollution only. Smoke stacks spouting dark gray clouds of toxic smoke into the atmosphere or choking exhaust from auto rickshaws, scooters and buses. These sources of air pollution are most visible to people in cities.

Indoor air poses many challenges to the health of the people not only in urban, industrial and rural but in office environment too. Indoor air pollutants slowly creeps but bring into significant health hazard and damaging the environment at par with outdoor air pollutants.

DTH’s concern lies with the requirement of monitoring and generation of data regarding noise and it provide full range including Leq, Lmin., Lmax., L10, L90, L50, Lday, Lnight, Ldn. Noise is among the most pervasive pollutants today. Noise from road traffic, jet planes, jet skis, garbage trucks, construction equipment, manufacturing processes, lawn mowers, leaf blowers, and boom boxes, to name a few, are among the audible litter that are routinely broadcast into the air.

DTH not only monitor the noise level at different work places with the latest data logging type sound level meters but can also take up consultancy in devising solutions for minimizing this.
