How can we control the SPM levels around a construction site?

With this one can take actions immediately on the construction site where there is more SPM, and can take action against the contractor or the builder if they are not following the rules and regulations. and it is seen that on a daily basis the SPM levels in most of the cities it is raising and it is a concern for the authorities to control the SPM levels, so to make sure that the SPM levels are kept in check one should give the environmental department more power to take strict actions.

Use of latest plants and equipments along with latest technology can reduce the overall air pollution around construction site............i.e. use of pollution free Hot mix plant and concrete batching plant, use of water sprinkling system in dust prone areas, plantation at construction site, use of environment friendly construction material and mixes.......etc. etc.........and of course Environmental agency has to work hard to make it implemented...

On construction sits, SPM increases due to following main reasons:

1. Actual digging of earth work.

2. Movement of transport vehicles on earthen tracks.

3. Presence of crushers very near to construction sites.

As for point 1, the dust generated can be greatly reduced by employing heavy machinery. It minimizes the dust, as well as reduces digging time.

Regarding point 2, it is worth while to make these tracks semi permanent by laying broken brick ballast or other such other cheap or discarded material. For those tracks which are not worth laying these, regular sprinkling of water helps. Sprinkling should be resorted to for alleartehn areas.

For point 3, Now crushers at the construction site help save transportation costs, but to make the SPM content to permissible levels, it is worth to locate them some diatance away.

some new rules must be created to control the air pollution and brown cloud formation near construction areas like barrication of site, sprinklers at dumpyards of aggregates and sand, plantation of trees, checking of puc of vehicles at the site,providing chimneys for generators or dg sets and also acoustic enclosing.

The impact to the enviroment caused by the construction industry is very high.  Right from the commencement activity, all activities are directly or indirectly deplete our natural resources.  

SPM is a measure of one of such impact to the ambient air. Just by controllig the symptom one can not get rid of the problem. The root cause for the problem is to be analysed and corrective and preventive action to be taken.

When we conduct Enivronment Impact Assesment on the constuction site the high intensity impacts can be identified and response strategy can be planned. 

Any such environment protection should start with "Creating Awareness" among the entire community If the organizations &  Individuals are not aware of the impact they are causing to the environment, "Policing" agencies like environment bodies will not have control over the acts.

To save our world the prime requiremetn is - All organizations and We Individuals should have definite commitment to prevent the nature by minimysing the impact to the environment. Then only any other measures  to save mother nature will be effective.
